Getting the right bike size is crucial, there’s no doubt about that.
When you are lucky enough to test ride a bike, then the process is quite straightforward – it feels good or it doesn’t. It’s as simple as that.
But what can you do when you’re shopping online (bike shops, marketplace, Craigslist and so on)?
The answer is simple – use bike size charts!
We have various methods on how to find the right bike size based on your height and/or inseam, so let’s take a closer look at these below.
Method One: Bike Height Chart – The Easiest
This method requires your height and provides you with the proper frame size measured in inches. If you need the results in centimeters, then jump to step 2.
Mountain Bike Size Chart
Your height / Frame Size / Marker
- 4’11″ – 5’3″ = 13 – 15 inches = X-Small
- 5’3″ – 5’7″ = 15 – 16 inches = Small
- 5’7″ – 5’11″ = 16 – 17 inches = Medium
- 6’0″ – 6’2″ = 17 – 19 inches = Large
- 6’2″ – 6’4″ = 19 – 21 inches = X-Large
- 6’4″ and taller = 21+ inches = XX-Large
Road Bike Size Chart
Height / Frame Size (seat tube height) / Marker
4’10”- 5’2” = 47”- 48” = XX-Small
5’2”- 5’6” = 49”- 50” = X-Small
5’3”- 5’6” = 51”- 53” = Small
5’6”- 5’9” = 54”- 55” = Medium
5’9”- 6’0” = 56”- 58” = Large
6’0”- 6’3” = 58”- 60” = X-Large
6’3”- 6’6” = 61”- 63” = XX-Large
Voilà!
These two are very generic charts, so we recommend always seeking more information from brands that you’re interested in.
Method Two: Calculating the bike size
- Take off your shoes and stand with your legs about 6″ – 8″ (15 – 20 cm) apart. Measure the height from the ground to your crotch.
- Be sure of the type of bicycle you want: Mountain bike, city bike or road bike. You can read about the different bike types from here.
- Now you can take your calculator and calculate the right size:
City bike – Leg inseam (cm) x 0,685 = Your frame size
Mountain bike – Leg inseam (cm) x 0,66 = Your frame size
Road bike – Leg inseam (cm) x 0,70 = Your frame size
(If your leg inseam is 76cm, then your right mountain bike size is 50 cm (20”), road bike 53cm and city bike 52cm)

The right saddle height has a very important role. If it’s too low, you won’t have enough power in your feet. In mountain bike racing, I have experienced that when the saddle falls one inch down from normal, I lose about 25-50% of my force. I better stop and let the group go, then fix it and lose 15 seconds but I do catch the group and can even get the next group ahead. So the right saddle height plays a big role!

The easiest way is to
- Lean to the wall with your elbow sitting on the bike (or let someone help you as shown on the picture)
- Put your leg to lowest point but parallel to the ground.
- Move your saddle up or down until you have a nice bend behind your knee. It should be something around 30 ° but don’t waste too much energy finding that exact angle.
Go out and ride. Does it feel good? If not, then adjust. Also, you can adjust the seat to front and rear.
But… which brand to buy? See our Best Bike Brands
TIP: If you got the right height, mark it down with some sharp object. That’s the best size chart ever 🙂 Some bikes have centimeters marked there, then keep this in mind.
What If I Got My Bike Size Wrong?
Then ask your merchant, if you can send your bike back to get the right one. If you don’t want to do that, then you can do the following things:
- Move your saddle to the front or rear
- Buy a longer or shorter stem. It changes your body position
- Buy a longer seat post
Give it time to get the feeling right. I remember when I got my first 29er mountain bike. It felt like a ship and seemed difficult to ride in narrow trails of the forest. Now I start laughing when I sit on a 26″ mountain bike because it looks so tiny.
Hi I am Tarun my height is 157 cms and inseam is 75 cm I would like to buy a Cradiac gunner pro cycle which has 18.5 inches frame and 700x35c tyre will it be suitable please suggest.
Hi Tarun,
The Cradiac gunner is a good hybrid bike. For your height and inseam, I would suggest a small frame, and unfortunately, 18.5 is too large for you. Remember that the wrong frame size can cause discomfort in the lower back and arm. You choose s small frame. For example, in our bike size chart, you fall under this: 5`1″-5`5″ 158-168 cm 25-30” 63-76 cm 15” / 16″ S
Hi Jeff.
What do you think is more important for choosing a road bike: inseam length or rider height? I’m 1.8m tall with an inseam of 80cm. So my height suggests I get a L but my inseam suggests I get a M. What would be better regarding comfort vs performance?
Thanks in advance
Hi Tom,
Both are important; however, the rider height is more popular because you can always base the measurement on frame length and make minor adjustments (stem length, saddle fore & aft, etc.).
Hi my name is Marie ,please can you help me out I’m only 4ft and 7inchs please can you let me know what bike size would I need to get
Hi Marie,
You need to get the smallest frame possible such as the XS size. Then, you also make sure to get a bike fit to ensure you are comfortable.
Hi Jeff,
awesome subject, thank you for great info.
I am in a bit of problem, I am 205cm and inseam is 102cm, it looks impossible to find proper Gravel bike.
Best I can find is Canyon Grail 7 XXL with 63cm.
I need another 7 cm of the bar, could I compensate that with longer seat post and stem?
How serious problem too small gravel bike poses?
Thanks
Hi Nikola,
Yes that is a general problem because proper frame size does not answer other issues like the length of your torso or inseam. You can get a proper bike fit with those suggestions in place.
Google tall gravel bikes for men and click on the link from cyclingabout. He made an awesome database of bikes for us tall folks. Canyon is great I am 201cm 6’7″ and bought the endurace as my road bike. Love it. Next bike is prolly going to be a huge size 71 dutch bike since I am getting older.
Hi Adam,
Yes, our bikes can evolve depending on our riding preference. The important thing is that we continue to ride.
I’m 6’7″ and my inseam is 35.5 inches (90 cm). I found a deal on a 2016 Felt F85X that I’m interested in buying. It is a 60 cm bike. Will it fit right with fine adjustments, or is it just too small?
Hi Mark,
I checked the suggested measurement for you. It says 73-86 cm or 19″ under XXL. So it looks like 60 is too small for you.
My height is 178cms please suggest me the frame height size of the cycle.
Hi Shaikh,
You fall under the medium range, with frame sizes between 16” / 17″. However, I suggest you still need to get a proper bike fit after getting the right bike frame to insure everything feels comfortable.
I am 5’5″ and looking to buy a road bike. Is the 48″ or 53″ frame a proper fit for me?
Hi Mike,
I’d say 48 or 50. But that’s not the end of the story. You still need proper bike fit to determine the length of your stem in relation to your reach.
I’m looking at a bike online I’m 5’8 and the bike a fahrrod tx400 speed hub the manufacturer says the 52cm frame is for 5’9” to 6’1” is this too big for me? Even though a medium sized frame is 52cm?
Hi Tony,
Did you check the Road Bike size chart? It says the range is between 5`6″-5`9″ (your height range) or 168-175 cm, and the suggested frames are 54-55 cm under Medium. There are overlaps and when this happens there are minor adjustments that you can do with the stem length, saddle fore and aft as well as other factors. These factors can only come into view when you get a proper bike fit because suggested frame sizes don’t cover other factors like body shape/geometry. There are people with longer legs vs longer torsos. According to the chart, a 52 frame is a bit smaller for you.
Hi, My son is 11 years old , 5’3 tall. Should we choose 26 inch or 27.50 inch trail bike for him?
Thank you!
Hi Xin,
26-inch-nimble and easy to manoeuvre.
27.5- Very popular in today’s MTB size and bigger wheels allow for a smoother ride.
However, the wheel size has nothing to do with comfort. Pay attention to the frame size in relation to his height.
Hi I’m 4.11 feet, inseem 29 inch. Is a 24 inch women’s bike (without crossbar) a good idea?
Hi Salma,
I assume you are talking about the wheel size. It is ok. However, you need to pay attention to the frame size. The 14” XS is your recommended frame size. You can do the bike fitting on top of that to make an adjustment to the proper seat height, stem length etc.
Hi….
I’m planning to buy a bike for ride and got a good deal for a road bicycle. But frame size is 52 and my height is 5’10.
Please let me know is it the correct size and worth of buying?
Thanks.
Hi Thanushka,
You need to get a frame size around 56-57-58 cm. This range falls under Large. Then get a proper bike fit to ensure comfort on longer rides.
What if you are in-between sizes? If you’re 176 cm? I guess what I’m really asking is, what if you choose a bike that is smaller or larger? Should I go for the larger?
Hi Jack,
It doesn’t matter. Find the nearest frame size; then, you can make micro-adjustments with your stem length, etc. We need a proper bike fit because our body shapes are different. The frame size is just the general indicator of what you should have. The rest is up to proper bike fit. For example, people who have a longer stem length will have lower back pain due to overextending. Looking into this can make a big difference.
No, you should go smaller if anything. There is lots of room to fine-tune up from the ideal. Precious little to fine-tune down. IMO, the most important indicator is when you are seated firmly on the saddle do you bottom out the stroke with your heel on the pedal? If so, you will be delivering max force when your toe is clipped in. I’m speaking from road-bike experience only, if you’re mountain biking, ignore!
I am having issues trying to find a trike bike for my husband. He has BIG feet, size 14 that hits the front tire! Another issue is his right foot has been cut into half. He wears a shoe with an insert. What is your recommendation?
Hi Sandy,
This is common with bikes that are bigger than the recommended size. What’s his height? What type of riding does he prefer?
I’m 6″2 which would be a 61cm or XL, but I have a 34″ inseam and long arms, I have two Specialized road bikes 61cm fit like a glove after adding carbon rims and profile bars plus a longer stem for long fast rides, just bought a Canyon Ultimate SL CL DB ei2 power meter Crank, Renolds Carbon AR41, bike at first it felt like riding a real light school bus? Was thinking of sending it back, then I figured it’s a different style of riding, not comfortable, get low and forward bent down and it will get up fast, still don’t know if I should of got a XL, or it’s just slower than all the hype?
Hi Katie,
I suggest you stick with the recommended frame size and make adjustments on the stem length, handlebar sweep, fore & aft of the saddle etc. These are things that influence your quality of riding.
Hi,
My problem is that I am 4’11” and am having a hard time finding a true gravel bike to fit my size. A local bike dealer recommended a Trek Domane AL 4 but it does not have the 40CM tires. I believe they were only 35 or 37. I have a mountain bike and we ride some pretty rocky/rough gravel and do a lot of climbing. I feel like they are just selling me a road bike (which I have as well) with a little larger tires. Do you have any suggestions?
Hi Tracy,
I believe you fall into this category: 4’11” – 5’3″ = 13 – 15 inches. Now if you can find a frame like that then we will move to the tires. Even if the original bike has a 35 or 37c tires, do check if the tire clearance is wide enough to fit up to 40mm tires. If you want a gravel bike that can accommodate a mountain bike size tire then you probably need to check out muster cross bikes. Gravel bikes are still road bikes after all..There are gravel tires that go up to 40mm. Look for brands like Continental, Maxxis, Kenda etc…
Great Guide! thanks
My only problem is the mixture of Imperial and Metric measurements – is sooo confusing. I am constantly converting.
Hi , I am looking to purchase a road bike . I am 5′ 6.5″ , inseam measurement is 75cm . Would I be looking for a medium frame ? Thank you , Owen
Hi Owen,
Generally yes, that’s your recommended frame size. However, don’t forget other things to take into consideration: stem length, saddle angel, saddle fore & aft etc. A change in a basic adjustment can also affect the overall ride experience. It’s like the spiderweb principle where moving a saddle fore or aft can impact your handlebar reach etc
I have a Stance 1 29er small and I’m planning to change my wheels to 27.5. What are the other parts to change.BTW Im 5’4″
Hi Mike,
Note that a 27.5” wheel will fit on a 29” frame and fork (provided the bike is designed for disc brakes). Since 27.5” wheels are smaller than the 29, it’s going to affect the geometry of the bicycle.
A few millimeters can make a difference. So you need to watch out for:
The reach, handlebar height, setback, saddle angle, and handlebar angle, stem length and saddle fore & aft.
If I’m trying to determine the right frame size for a hybrid bike using method #2 above, in which category of bike of the three you list does a hybrid fit?
1. City bike – Leg inseam (cm) x 0,685 = Your frame size
2. Mountain bike – Leg inseam (cm) x 0,66 = Your frame size
3. Road bike – Leg inseam (cm) x 0,70 = Your frame size
My inseam is about 34.6″ or 87.884 cm
If a hybrid is considered a city bike as it is using method 3, then my ideal frame size is 61.5 cm
But if a hybrid is considered a road bike, then my ideal frame size is 61.51 cm
Please let me know which is correct using that method.
Thank you,
Lee
Hi Lee,
Either one will work. Remember that the frame size is not the end of the story. There are incremental changes that you still need to do such as the stem length, the saddle fore and aft etc. That is why bike fitting prevents pain and discomfort. If you ask me, I’d go with choosing the frame that is standard to my height, then then make changes from there. The inseam measurement is crucial for the standover fit and it is good you ask about this.
Nice, I loved that guide about bike sizing. Thanks!
I tried to leave a message or reply but it said I was a spammer could you please get in touch with me this is concerning my my six-year-old son he is disabled but he had his bike still on it was a special kind of bike wonder if you can help me figure out how to what kind to get him now or how to go about it thank you very much I’m going to leave all my info on this is not a spam
Hi Ruth,
It is ok, comments are always moderated first to prevent spam. Another type of bike that you might need to look into is the trike type. I didn’t know he is 6 years old and not 36, which I am sure is a type. Below is a link to that type of bike. Check if you can find a version for children.
Trike bike.
General Kids bikes
My 36 year old son had his bike stolen . It was a special bike I’m not sure what kind to get him now because it he shattered his pelvic bone shattered his tailbone and dislocated his femur bone and barely able to walk and now he can ride a bike . He was 63 now he is 6 ft 2 I don’t know what kind of bike to get him and I don’t know if I’m trying to collect money to help figure out what to do cuz that’s his only type of transportation he can’t walk very good but he can ride his bike is there anyway you can give me some suggestions where to go or how I can get some help and guiding to get him a bike and maybe help getting funded to help him get a bike thank you very much
Hi Ruth,
Sorry to hear about your son. Judging from his condition, he needs a bike that is not too aggressive, and also provide comfort in riding. We will be removing all sporty bikes from the equation in this scenario. I would suggest a city bike or Dutch bike type. These bikes are built for comfort and also for riding that is more laid back and upright. I will be posting links below so you can choose which ones you think suit him. Do let me know if you have more questions.
City bike/ Dutch bike type
Cruisers
This is a very helpful blog post. I really appreciate the efforts you’ve done for the information.
For me buying a bike is always so confusing and it takes longer than average. All I ask for a comfortable bike that fits just right and is within my budget but there is always some issues with right fit. I am 5ft 11 and this whole thing about calculating bike size is confusing. Then there are doubts about the right bicycle weight for my need. I hope you will continue to educate us more approaching things in a most basic manner.
Hi Amit,
It’s pretty simple actually. Just look at the frame closest to your size recommended in the chart. Then you can make incremental changes from there, like stem length, saddle height etc. We all have different body shapes. These numbers are just guidelines but the bike fit is still up to you.
Why are bike sizes in CM when posting in US ? Ive never used the Metric system except for choosing a socket while working on a Japanese Car ?
Hi Bryon,
We have contributors around the globe so sometimes they use their systems. Google can always covert that for you 🙂
Such a good job and love the article! Thank you
If you are always on off-road travels, you need a bike more durable and heavy. So, how much does a bike weigh? The average weight of a typical road bike would be 18lbs. The road bike-style hybrid bikes weigh 26lbs while cruiser-style hybrid bikes come in 32lbs. Mountain bikes are one of the heaviest kinds. They can weigh up to 28lbs because of the extra gears that come with them. I think you can be more confident on highways when riding heavy bikes.
Hi Dalton,
It all boils down to preference. I know people who love to ride highways using the hardtail bikes. They love the stability and comfort. Bikes with thicker tires can stand potholes and road imperfections. Weight is a secondary concern for many people. But a lighter bike feels nimble.
If you prefer better acceleration and need to transport your bike from one place to another, lighter ones are your best choice.
I am a stubby guy with short legs and about 5’6′ and I like this bike a lot (21 speed Shimano) (pasted from Ebay into the website slot). Do you think it will be comfortable for me? It’s 700C. Thank you very much in advance.
PS Any thoughts on the quality of the Shimano brand?
Hi John,
Shimano: reliable Japanese technology. I can say that from experience. As for bikes on websites you need to check for the sizes. You belong to the medium category 54-55 cm. However, this is not the end of the story. You still need to get a proper bike fit to ensure that the stem length, crank length, saddle fore & aft etc all work for your comfort.
My height is 5 feets which is best&cheapest bycle
Hi Kalavathi,
An xs frame would suit your height. Do get a bike fit because having the right frame size is not the end of the story. Check out our entry level bikes.
Hi, I am 5’8 and a half. Recently bought a 16 inch frame bike with 27.5 wheels. My question is should I have bought a 17 inch frame instead?
Hi Marvin,
No it is ok. It is still in the medium range. Do make small adjustments to ensure you get a proper bike fit.
I am a 4ft 10 inches tall lady having a rather hard time finding a correct sized bicycle (heritage styled, low step through) which can have a child seat fixed to the rear of the bike. My main purpose will be school drops for a 4 year old. Any recommendations regarding the frame size? Thank you.
Hi Anu,
This is under 14” or XS frame size. You start with that and make other adjustments with seat and stem.
I am 6ft 2 and this whole thing about size calculator is confusing. How do I approach it in the most basic manner that even an uneducated person will get down to working the numbers and size easily
Hi Ronnie,
No need to exhaust your mind about these things. The size recommendation is just a guideline to find a suitable size of frame based on your height. The real sizing happens when you do the bike fit. For example, you are 6’2, so your recommended frame size is between 18″ / 19″ under the XL category. However this does not take into account the kind of stem length or saddle fore and aft that you should have.
A bicycle with insufficient reach is usually uncomfortable as it causes cramping. That’s the reason why you must measure your bike stem for optimum performance and comfort throughout the road. The first thing to do is to place your road bike against something firm. Know the length by measuring from the middle bolt of the bike’s headset top to the center of the handlebar. A bike stem length usually runs in 10 mm increments and starts from 70 mm to 140 mm. The measurements you get are possibly off by a few millimeters, you must adjust the measurement to the closest 10 mm increment.
Hi Dalton,
Thanks for the added input. Yes the frame size recommendation is not the end of the story.
Stem length is an essential aspect of bikes that can affect your body comfort and performance on the road. It is vital to know the present length of your bike stem before you can change it.
Hi Dalton,
That is right. We always go with the frame size as the primary step. The we move to incremental adjustments with the stem, handlebar angle, saddle fore & aft etc.
Hi, I’ve found a bike with what seems to be an uncommon frame size/wheel size combo and have having a hard time figuring out the height range. It is a mountain bike with a 16″ frame and 29″ wheels, what would be the ideal height range for a bike of this size? Thanks!
Hi Sam,
Yes, the tire size can have an influence on the standover. However, if there is an issue, it’s insignificant. 16″ is for medium height riders and I have seen riders in this height that use 29″ wheels without issues. It’s a matter of preference. So I would say it is under medium: 5`5″-5`9″
I have a long torso and feel all bunched up on my bike. The seat is at the right height but when I put my hands on the handle bars and pedal my knees are feeling strained when in full flexion. I wish I could move the wheel base apart. Is that an option?
Hi Dora,
The problem is not the wheel base. It is a matter of stem length and saddle fore & aft. Why not try to experiment on moving the saddle further back, and getting a longer stem. I suggest you get a bike fit that way you wont get into trouble of buying bike parts that will not solve the problem.
I don’t understand the chart. I usually decide by Wheel Size not frame when buying a Road Bike. 27.5 inch is my preferred WHEEL SIZE but sometimes I see Bikes specified as 700. What does that mean? How come all the different ways of measuring the size of a bike?
Hi Wendell,
Let me help you with this one. No, don’t ever decide buying a bike by wheel sizes. When you see a 700, it stands for 700c which is a road bike designated wheel size. 27.5 is a mountain bike wheel size. 26 used to be the common size. Now we have 27.5 and 29. The chard is the standard base for measuring a bike frame size that is right for you. But it is not the perfect way. You still need to consider little adjustments like saddle angle, stem length etc because we all have different body shapes. For example if you stand around 5`6″-5`9″ and you want to buy a road bike, then you need a frame size around 54-55 cm which falls under medium. Then you need to follow that up with a bike fit.
Hi Guys.
I want to buy 2 MTB for some children in Thailand. age is 8 and 11 years. Height and inner leg in Cm is 137/67 and 120/60. Since i will buy this through internet i thought its best to ask here.
Regards Sead
Hi Sead,
They fall under the xs category frame size. Check if you can find an mtb for kids size. They still need fitting when they receive the bikes.
Hi,
I’m 5ft 7 inches Male
What size bike would suit me
Hi Indrajeet,
It depends on what bike you want. For MTB that’s medium and you need to get a frame size between 16” / 17″. For a road bike that’s still medium. You need a frame size of 54-55 cm. Don’t forget to get a bike fit.
I am 5’ 3” tall female 66 years old. What size Ebike for me? 26 or 24 inch?
24 or 24 are ok. You need a small category bike frame.
Hi I’m 5,2 lady what would be the right frame size for me oh and I’m 13st I’m working on that bit ….😆
Hi Donna,
Your size falls under the small category. For MTB that’s 15” / 16″ For hybrid a 15” is perfect. For road bike it crosses to xs with 49-50 cm. You still need a proper bike fit though.
Hello I’m 6’1 and have no idea what I’m looking at, I’m looking for a bike to exercise with also commute in future.. what size should I be looking for and what type of bicycle should I be looking at?
Hi Richard,
Let me help you with that. Are you into city and road riding. Perhaps you need a city bike or road bike. 6’1 falls under 58-59-60 cm frame and these numbers belong to the XL category. This is equal to an 18″ frame for city bike/hybrid. If you are not into speed, and simply want a decent commute then a city bike/hybrid suits you better with its relaxed geometry.
Hi Jeff! I would like to ask about 28 inch bike and for what size of person it’s appropriate to use. Thanks!
Hi GlY,
Are you sure that is the right frame size you are looking for? Please consult the charts carefully to get the right frame size for you.
Hi
I’m 5 ft female
What size bike would suit me
Hi Lorraine,
For MTB that’s xs. It’s the same for road bike. You still need a proper bike fit to ensure you are comfortable in the bike.
Hello, I am 4’11” the chart is saying I need to purchase a 14″ frame, which seems so kid-size small. I’m only riding for exercise purposes, nothing extensive or professional. If I purchased a 24″ frame would I be at a huge riding disadvantage?
Hi Mickie,
Indeed. Although let me assure you that this is not the end of the process. You still need a proper bike fit because having the recommended frame size does not equate to comfort.
Hi,
I’m looking for a best suited bike. I’m not an enthusiast. Just starting to ride primarily for fitness. I wanted to know the type of bike that’ll be the best for me along with the sizes.
I’m 25 yo with height of 5’9.
Any help would be highly appreciated.
Hi Nishchey,
If you want a bike that offers a relaxing and comfortable ride, then a city/commuter bike is the right one for you. These bikes offer you the best of both worlds: commute and exercise without feeling like you are competing for a Tour de France.
Hello!
I am 5’11 but my inseam is 34/35″ so I am not sure which measurement is more important as they fall on wildly different frame sizes? I think possibly the inseam is more important, but I’m not too sure.
Hi Sarah,
Both are important. However, we generally start with the height and the right frame size. The rest will follow: saddle fore & aft, saddle height, standover height, stem length etc. Having the right frame size makes it easy to make small adjustments afterwards.
Hi, I’m 5’11. I wonder if I can go for medium size mountain bike frame?
Hi Vichet,
The height falls under the 17″ / 18″ Large category. That’s the recommended size however, consider getting a bike fit to ensure comfort.
I’m a single mom trying to figure this out. My son is 13 and his height is 5’6”. He says his 26” bike is too small. Will the 29” be too big? Thanks!
Hi Minnie,
Your son falls under the 16” / 17″ medium category frame sizes. 29″ are the trend these days anyway. 27.5″ or 29″ is ok for him. If he is riding on both trail and road then consider getting a tire width or 1.8 or 1.9 is ok.
Hi, Jeff! I am 14 and my height is 5’8 and my inseam is 2’8 inches. Which mountain bike frame size would you suggest?
Best regards,
Jacob.
Hi Jacob,
You still fall under the 16” / 17″ frame sizes under medium. Bike fit should include all adjustments in stem length, saddle fore & aft and even crank length.
Hi Jeff, Good day! I unconsciously bought a bike which’s frame size is larger than recommended (My height is 5’3 the frame size that I bought is 19) (I don’t have problems reaching the ground when I stop) my question is can I still use the frame size without problem?
Hi Justin,
Wow, your recommended frame size is 15″/16″ which is small. You bought an XL. I have my own question. Is it giving you aches and pains during long rides? Is it possible for you to have a bike fit appointment to see if adjustment to saddlebar angle, stem length and saddle fore&aft can make you more comfortable? That frame size is way too big for you.
HI Jeff,
Thanks for good information here.
I’m 5′ 10″. If I choose 29″ wheel, what bike frame size do you recommend?
Hi Hwan,
You can get a 17″ / 18″ under the large category.
Hi!
I am 6’1″ and weigh 100+ kg. I have cycled 29er MTB. Now Intend to buy a hybrid.
1. Which size 19″ or 21″ should I go with?
Thanks
Hi Ujjwal,
The ideal size for you is a 18″ which is an XL. A 19″ would be closest. Do make necessary bike fitting in terms of stem length, saddle fore & aft etc because they would help in your comfort.
Hi, Jeff! I really appreciated your article, it’s very informative. I have a doubt: my height is 1,67 cm (5’6”) and my inseam is 73,5 cm. Which road bike frame size would you suggest? A 50 cm or maybe a 52?
Best regards,
Aaron.
Hi Aaron,
You fall under the medium category so a 50 would be perfect. However that is not the end of a good bike fit. You do need to take into consideration other factors like stem length and seatpost fore and aft.
Hi, I’m 5″10 ½ and looking at Hybrid bikes. What size should I go for?
I can do a medium with the seat slightly raised according to the person in store but the handlebars don’t adjust. Is this a problem?
Thanks!
Hi Dom,
Yes the person in the store did make a valid suggestion for those frame sizes that are smaller than your recommended size. You fall under the large category and a 17″ frame is a good one for you.
Hi Jeff
I’m 5’5″ tall and weigh 173lb. What size frame should i get for a mountain bike or hybrid? Have a great night/day/afternoon (where ever you are.
Cheers
Tom
Hi Tom,
Greetings! A 16” / 17″ under medium is the one for you.
Hi.
I’m looking into getting hybrid/road bike with straight bar. I found a nice Cannondale Quick that is size 58 L/XL. I’m 5’10 and 185LB. Is this bike too big for me or would I be able to fit on there comfortably? If not, what size hybrid or road bike should i go for? Thanks
Hi Mensur,
That size is ok for you since it falls under the large category. Do get a bike fit if you can to ensure that you have the proper stem height, correct handle bar angle and saddle angle/fore and aft. These things are crucial other than getting the right frame size. You might have the right frame size but if the fit is incorrect then you will never enjoy the ride due to discomfort/pain issues.
I found a nice Felt Z85 road bike for $210. Do you think it’s a good brand and would you recommend? Thanks
hi Mensur,
Don’t underestimate this brand. It is a good brand and even earned a good review in Cycling Weekly. Yes I would recommend it 😉
I’m looking at adult tricycle’s. I see 20″, 24″, and 26″.
I’m 5’10” and 250 pounds. How do I know which size adult tricycle is right for me?
Hi Julie,
Get the 26″ because it fits your height. Is this an online purchase? Because it is best to try out the tricycle first before taking it home. This way the dealer can make necessary adjustments in terms of seat height and handlebar angle.
If I am 5 foot 3 inches, what is the best bike size for me?
Hi Mishera,
For MTB, it’s size small (15” / 16″)
for hybrid, 15”
for road bike, 51-52-53 cm, also size small.
I weigh at least 250 and I’m 5’5” how do I choose the right bike with the right tire size?
Hi Maria,
Is this your first time riding?
Consider the following:
1. If you do not like gravel and want to ride on a smooth pavement then get a road bike(tire size is 700c with either 25mm to 32mm width).
2. If you want something for the trails then get a mountain bike(26″ 27.5 or 29″ are options but I think you should have the 1st and the 2nd option).
3. If you are an urban and casual rider then you need a hybrid/beach cruiser/city bike type.
What’s a good beach cruiser for someone 6’4″,something very comfortable and possibly step through. It would be nice to have shocks. I haven’t seen a lot beach cursers with shocks
Hi Wes,
Beach cruiser for tall people is a good link to start. We do have available beach cruisers through this link. You need a 19″ or XXL frame size.
Hi,
I want to buy a gravel bike. my height is 169 cm and inseam is 77 cm. What size that fit for me?
Thanks
Hi Fidel,
Gravel bikes still use the same charts as the road bikes. You need a frame that’s around 54-55 cm, under the Medium category. You also need to have a proper bike fit to ensure you have the right stem length and seat height.
I am 50 yrs old and 5’3″ (159cm) looking for a hybrid one. Most of the bikes are 17″ frame size.
Hi Dominic,
Yes, 17″ too big for you. A 15” under the small category is the right one. Personally? I would prefer a smaller frame over a large if you want better control of the bike.
Hi.. I am about to get my first road bike. Looking forward to get the sl7 comp 2022 or sl7 tarmac expert 2021. I am 5’5 with 30 inseam. My LbS only have a size 49 cm and a 54 cm on the bike I want. I wonder if the 49cm will work on me? I’m not a racer and I only ride flat trail and some hills like bridge.
Hi Coseleng,
Although adjusting stem length and saddle fore & aft can help compensate for the frame length, I would still suggest a proper bike fit wit your LBS. This will ensure that you are comfortable with the necessary adjustments.
According to your chart my son looks to fit the 14″. He is 3ft 4 and 1/8 inch tall and 17 inch inseem. He will be 5 next month. Wanting to get a bike with training wheels. I’m anticipating a big growth spurt over the next year. He hasn’t grown much in the past year. Do you think he’d handle a 16″ training wheel bike? Thanks.
Hi Raymond,
16″ is a standard size for kid’s bike. However, keep in mind that the age is not really a true indicator as to the fitting. There are 5-year-old kids who may fit on a 16-inch bike while a 4-year-old may fit on a 20-inch bike!
Hello. I am 5 foot 5 1/2 inches. I just got a Cannondale Habit 2 in a medium frame. when I stand over, my crotch is touching the post. I wonder if I should’ve gotten the small frame?
Hi Franke,
How does the ride feel? The ride is more important than the standover height. The thing about your height/frame recommendation is that it borders between medium and small. Sometimes the front shock can also alter the bike’s geometry especially those with more than 120mm of travel. Try to test the ride first before deciding to get a different frame size.
hi i am 5.5 inch tall but my favourite cycle has ony 18 inch . should i take that?? plz reply..
Hi Jaber,
You are probably talking about an MTB frame size right? If you look at the MTB chart closely you’ll notice that 18″ is bigger than your recommended size. You can still make changes in terms of stem length and handle bar angle. You can also adjust the saddle fore and aft. It would be better to get a bike fit though.
What size would a 12.5 inch Giant mountain bike be for? will it work for 5 ft 1 inch woman
Hi Loki,
That would be under xxs small. That’s for kids.
I am 5’11”. I am having Ankelosying spondilytis. which size (tyre size and frame size) would be good for me.
Hi Santosh,
Sorry to hear that. A frame size of 17″ under the large category is good for you. As for the tire size, a 27.5 is perfect. You can also decide if you want an MTB or a hybrid/city bike style.
Hi Jeff. Thank you for this guide. Do this work for both 27.5″ and 29″ mountain bikes? Does the wheel size impact the frame size required?
Hi Makmudul,
Not necessarily, however it can impact your reach or standover. These things can be mitigated by shortening the stem length ot lowering the seat post.
Hello I am a woman who stands 4ft 6i inches tall and I’m 150 lbs in weight but I am looking for a three wheel adult tricycle hybrid that’s if I have the right name for the bike but I’m looking for assistant biking since I haven’t rode in about 10 years and I’m wanting to get into shape so could you please help me out with information and advice thank you
Hi Patricia,
Best Adult Tricycles looks like the best link to check to get you into adult tricycles. As for the sizing, this link seems to be the best answer for you.
My husband is 6′ tall and weighs 245 lbs. Can you tell me what size bike he should get for the bike path and a bit of off road biking? This is his Father’s Day gift.
Hi Chris,
Gravel bikes(58-59-60 cm size XL) are the rage today. He it’s mostly gravel path with casual road riding then this is for him. If he wants to get an MTB then choose a hardtail(18″ / 19″ size XL).
Good information.
Hi Jeff. Thank you for this guide. Does this work for both 27.5″ and 29″ mountain bikes? Does the wheel size impact the frame size required?
Hi Brett,
Personally I think not really. However tire size can impact handling. Bigger tires are not as nimble as smaller ones. You can make adjustments with the seatpost height.
Hi,
I’m thinking of buying a used Kona Jake gravel grinder. I’m 5 11 and the used bike is 54-55 (medium frame I think). I’ll use it for longer rides on rural roads and some gravel roads. It’s 2007 for $400 Canadian. Is this a good fit for a casual rider? Thanks.
Hi John,
The answer is yes. It usually gets a 4 out of 5 stars on the average based on many online reviews. So you can say it is a decent bike to have for your gravel rides.
We are looking for a mountain bike for my husband, he is 6’10”. I have a 26” bike but he says that’s way too small for him. While shopping, I get very confused because the bike will say “29inches wheel size”. Is this what we are looking for? I understand that the frame and wheel size are two different things. In most cases, I can’t find where it says “frame size”.
Hi Rocio,
A 19″ + XXL frame size and a 29” wheel size is recommended for him. Frame sizes have values like 17”, 18” or 19”.
How do.you measure for tricycles for seniors?
Hi Suzzane,
Although we don’t have a size chart for tricycles, I found this link for you. I hope this helps 🙂
This is VERY BAD ADVICE. You should 100% try your bike before you buy it. There are so many things to consider and buying the wrong one can be expensive to make fit you properly in the long run and cause you injuries.
Hi Nate,
My apologies for not expounding enough. The problem these days is that most of the time, bikes are available onlije. So there is no option to try it. However you do have an option to send it back if you have exhausted all possible means of resolving the issue: shortenint or lengthening stem lengh, the saddle fore and aft, saddle layback etc. We understand that the human body is unique and there is no “perfect”
Size.
Hi, my daughter started doing Mountain Bike, and she has a 24”. She is 9 1/2 yro and 1,30 mt heigth. I am a bit lost, cause for normal bike would be all right… but I think this Mountain bike is big…Which would be the Mountain Bike for her? Tnx
Hi Vera,
What’s your daughter’s current height? And what’s the frame size of the mtb?
Im 5’9 tall idk whats really the size of MTB frame for me..riding style is XC
Hi Projie,
You already fall under the 17″ / 18″ large category. In case you are planning to buy one, you can see it under the charts.
I am 6 foot 4 and have a 36 inch inseam and have a really hard time finding a big enough bike. I am looking for a hybrid, I do no want a too low handle, but it is still for exercise on the road, Any recommendations?
Hi Christian,
You need a frame size that’s 19″ XXL. Check this link: Best Hybrid Bikes
Hi,
I have gravel bike XL or 60 cm. I’m 187cm tall and my inseam is 89cm (barefoot), did I bought too big bike, because I turned the bike stem upwords for better position some taller then me ride L size, but at first was little to small for me so I chose for XL.
Hi Andrej,
XL is the right size for you.
Is a city cruiser with dimensions of 53″L x 8″W x 28″H the right size for a woman whose 5’8″ tall?
Hi Dea,
Your frame size overlaps between medium and large. So yes that will do. However, the ideal is a
16” medium.
I’m looking for a mountain bike for our 13 year old son who is around 5’4 right now and still growing. I’d like to get a ‘long-term’ bike for him if possible. He can just barely clear the top bar of my large size frame Norco mtb. There are some very good used ‘large’ frame bikes available right now, do you think it would be overly difficult for him to ride comfortably on a big bike while he continues to grow?
Hi Jeff,
I have seen kids riding adult bikes and doing it off the saddle. However, for safety purposes, you can get him a size undrr 15” / 16″ Small. This is good for a fee years.
Hi. Guess I will ask too, I’m 5’6″ with inseam 32″, what size would I need, would a 17″ work???? Thanks! The lady at the bike shop had a 14″, I think it was decent when I stood on the ground, she said it was wrong for me, they only had a 17″ in another bike, which I liked, but felt just a tad off in height of bike. Also, it was a Del Sol Flow 1 and 2. Are those good bikes? I want to be able to ride in a paved park, plus a few minor paved hills. Thanks so much!!
Hi Kim,
If you mean MTB frame then 16” / 17″ are both ok for you. You can make adjustments with the stem length…
I already purchased Giant Contend AR1 2021 Size Large. Not sure if it is right for me..
Hi there! Could you please help me out here? My height is 182 cm. Inseam – 86 cm. Which size would f”fit me best?
Thanks in advance!
Hi Shain,
As long as you don’t got above or below these frame sizes then you are ok:56-57-58 cm, and yes these are under the large category.
That’s a huge inseam!
I’m 183 and also have a giant contend in a large. It feels great
Hello, I am 5’8″ with an inseam length of 32″. Do you think a 53cm frame would be a good size for a hybrid bike?
Hi Kenny,
53 is too small. Get somewhere 66-78 cm or 16” under Medium.
Hello, this is a great place for information. Currently I’m on foldie (second hand) and looking to get a new roadie (but with straight bar). But I’m confused with sizes. From various manufacturers.
I’m 5’ 8”, with an inseam of 30.5” & I weigh 86kg.
Looking at Trek, Giant and perhaps an online Yoeleo(hope they sell ready build bikes).
Hope you can give me a hand to my query. Thank you. Victor.
Hi Victor,
I understand what you mean. You need to stick with frame sizes between 54-55 cm, the latter being your sweet spot.
Hello.
I am looking to buy a mountain bike bicycle. I am 6’2″ and 275 pounds and 32″ inseam. What size of frame/wheels do i need. Thanks
Hi Florian,
You should get a 19″ + XXL frame.
Hi, i’m 4’8 what size should i get? Please help.
Hi Jamaica,
You need a frame that’s < 14″ or XS
Hi,
My height is around 177/8 CM and inseam 32″ but have Releigh Gravity 15, do you think I can use it with some adjustment …?
Hi Atty,
Your height falls under the medium category 16” / 17″ but you have a small frame size. You can make adjustments with the stem length and saddle fore and aft. You can try a layback saddle too.
Hello! I’m looking for a Mountain Bike but i’m not sure what tire size is right for me. I’m 5’10 and have an 81 cm inseam. I know I have to look for a bike with a 17-18″ frame, but I was wondering whether I should choose a 27.5 or 29 inch wheel. Thanks!
Hi Chris,
It’s up to you. Some prefer the 29” because they are great for offroad and navigating through rock gardens. However, the 27.5” tires are more responsive. 2.0 is the standard tire size for mtb.
Hi I’m looking forward a beach cruiser and I’m 5’3” an about 200 lbs I’m thinking 24” tires please advise. Thank you
Hi Nancy,
You need a frame size that’s around 15” which is under Small. Did you check pir list of Best Beach Cruiser Bikes of 2021?
I am 6’3 and What size Mountain Bike do I need? (I find this article confusing)
Hi Austin,
I am glad to help. Your ideal frame is something that’s 19″ under XL.
Hello.im 5.10 and my weight is 125 kilo which size of rod bike?tnx
Hi Arnel,
You need 56-57-58 cm frame sizes under the Large category. 57 is your sweet spot.
Hello, I’m looking at an old fashion 1950s Raleigh road bicycle, Frame size is 22 inches. I’m 6’1″ 220 would this bike be to small for me ? Appreciate the response back.
Yes,
You need a frame that’s at least 58 to 59 cm or 23 inches.
what will be the right wheel size for me . I am 6 feet hight & 110KG heavy weight man
Hi Salim,
It depends on what kind of bike you have in mind: Road bike or Mountain bike? For MTB 27.5 and 29 are ok.
Hi. Maybe you can help I’m 5’0”. Inseam is 26 inches. What size bike. I know XS but in inches
Hi Joy,
Something 14″ and below is ok for you.
Hey! Im looking to buy a road bike. I am 5’6 and weigh about 188lbs. which size should i go for?
Hi Costa,
54-55 cm Medium is ok for you. Have you tried checking out our Best Road Bikes For 2021?
Hello! I am 162 cm for my height with a 81cm inseam. I am so lost on what size mountain bike to purchase. Can you point me in the right direction?
Hi Jen,
You fall under the 15” / 16″ Small category.
Hi there. On what wheel size are these charts based on? E.g. if I have a 27.5 or 26 inch wheel on a Small MTB frame, will it be ok for my daughter (1.5 m tall)? Or should I rather go for a XS frame? Thanks
Hi Andre,
This is pretty much standard across all bike websites. Your daughter’s recommended size: 13″ – 14″ with 26″ wheels. This is under XS.
Hi. I am looking to buy an adult tricycle. I don’t know if I need a 20 inch or a 24 inch tricycle. I am 5 ft 2 1/2 in tall and weigh 215 lbs.
Hi Cecilia,
Interesting question as it is rare for me to get this. To answer your question. we do have Best Adult Tricycles review which you might care to read! You need a small frame for comfort, preferably a 15″ frame. 🙂
im 5,10 and still growing I want a SANTA Cruz Bluz however I’ve raced the medium frame and it feels slightly short on the extended climbs but great for flowy extensive decents I’m not sure which frame size to go with but with xc racing I’m leaning toward large and comments?
Hi Lennox,
You already belong to the Large frame category. I suggest you look into that. There are also small changes that can be done during a proper bike fit.
hello , i am 170cm high , and my inseam is 78cm . I have good price for Giant Contend AR1 road bike in M size.. is it to Big for me ?
Hi Luka,
Medium is the perfect size for you 🙂
Does weight of rider effect the required size of bike? Iam 5’4 and 270 lbs
Hi S,
No. However, there are necessary adjustments needed to offer comfort. Like for instance, getting too aero on a road bike might be hard for those who are either new or trying to lose wight. In your case a 51-52-53 cm or 15” and 16” are the right sizes for you. They are under the small category.
I am 4’6” and weigh 130 lbs. can you suggest a bike for me? I’m not great with balance, but I like to ride.
Hi Cheryl,
You need an xs(extra small) frane size. I suggest you get this type of bike. Best Woman Cruiser Bike – Firmstrong Urban Lady Beach Review
Is there a bike that allows a double Thule stroller attached via trailer attachment, and then a child seat? (3 kids in total). We live in the Yukon Territory in Canada. So something for that weather and is good with all terrains. Fat bike would probably be better? I am 5’2 and 110-120 lbs!
Hi jt,
Is this what you are talking about?
Or maybe some other Review of Thule Chariot Lite Bike Trailer
Do let me know if you want something else. By the way, your size category is small so you need a frame size between 15” / 16″. Cheers!
Hello and thank you so much for this great resource as well as your time. I’m truly impressed at how many questions you personally answer. I am returning to biking after several decades and looking at classic, vintage-style Mixtes and Roadsters. The Bianchi Venezia Gent in their beautiful, original, milky Celeste has really caught my eye. I am female but prefer the seating position on the men’s frame as opposed to the Venezia Dama. I stand just at 5’5”. Plus we all shrink with age, and I want to enjoy this investment for many years to come. The Venezia Gent is offered in 49, 53, and 57. Should I opt for the 49 and just raise the seat, if needed? Or should I go for the 53? Thank you!
Hi Dawn,
49 is too small. Your frame size is under “small” so 51-52-53 cm are good for you. Yes you can take the 53 🙂 Oh and yes that’s a great brand!
Hi, I’m 178 cm with inseam of 83 cm. Please advise what should be the right size for mountain bike? Thank you.
M/L
Rider height: 165.5 – 179.0 cm
Inseam : 77.0 – 84.0 cm
L
Rider height: 177.0 – 188.0 cm
Inseam: 83.0 – 88.0 cm
Hi Terrence,
You overlap between M and L. Your sweet spot is 17”. I’d say between 17 and 18 🙂
Hi I am 169cm height with 76cm Inseam. I’m planning to buy a road bike endurance type Cannondale. What frame size will be suitable for em
Hi Jonathan,
Your size chart is:5`6″-5`9″ 168-175 cm 54-55 cm M.
Hi
What would be the appropriate frame size required for a boy with 139cm height and his inseam is 64cm.
Hi Subin,
Try this:4`10”-5`1” 147-155 cm 24-29” 61-73 cm 14” XS
Great article and thanks for sharing!
My height is 164cm and my inseam is 77cm. … I was looking at a Canyon Endurance road bike and it’s Women’s model – I would be 2XS but the 3XS and 2XS bikes have smaller 650b wheels.
I have shorter torso and longer legs, weight 55kg.
Do you recommend that I follow based on their calculation or should I get XS instead?
Thanks and appreciate it! 🙂
Hi Jessica,
You actually fall under small category. Your frame chart says: 152-160 cm 49-50 cm XS
5`3″-5`6″ 160-168 cm 51-52-53 cm S. Don’t forget to get a bike fit 🙂
I am 5’6″ with a 29″. I am male and am looking to get a road bike and start getting back into riding more regularly. I see quite a few used 56 cm frames for sale and it looks like that would be on the top end of what I should be looking at. Would this be ok or should I look at a smaller frame? Thanks.
Hi Tracy,
As long as it is within this range:5`6″-5`9″ 168-175 cm 54-55 cm M
Hello Sir,
Finally, got my bicycle today. It’s Raleigh Strada (18.5 frame, 29er). I got a best bike just because of your supporting suggestion. Enjoy biking now…..thanks a lot
Hi Sarmor,
Congratulations! I am sure you will have many great rides with that bike. Enjoy and thank you for the support 🙂
I’m 5’7 with an inseam of just shy of 34 inches. What size of womens road bike would i need?
Hi CP,
A medium frame size of 54-55 cm is best for you.
My husband is 6’5” and it’s been difficult to find a bike for him. At this point I’m planning to modify a 29” bike to better fit him vs finding the perfect one ready to go . I read on your page about moving/extending the seat and maybe the handles too. Do I buy a seat extender? What about for the handles? Thank you so much!! 🙂
Hi Tracy,
There are layback seat posts that you can check out via Google and YouTube. I suggest you check them out before buying one. You can also get a longer stem. However, before getting these, please research on the pros and cons. Not only that they affect bike geometry, they can also affect handling. That is why a proper bike fit is still the way to go.
I’m looking into Trek bikes in size L because XL availability is difficult because of COVID, will L be fine
Hi Zaid,
Bike frame sizes can overlap between L and XL. That is why bike fit is important. What’s your height?
Hi there,
I was lucky to come accross your web page, as I am in a bit of a dilemma trying to calculate the IDEAL road bike frame. My inseam is 76cm and total height is 168cm my “total arm span” is aprox7/8cm more thatn my total height. I am interested in buying a Bianchi Via Nirone 7 with the sloping frame desing. the bike frame i found is a 52cm on the seat tube and 53cm on the horizontal. My thoughts after reading your page and charts, is that a 52cm seat tube would be ideal.. is this correct ? many thanks, Martin
Hi Martin,
53 and 54 are ideal. You can make micro adjustments via stem length and saddle fore and aft.
Hello – I am looking at 2 different used Trex Navigator 200 comfort hybrid bikes and deciding on which one would be better size for me. I will mostly be riding on road, soft paths on dirt, grass and the lightest off road conditions. I am 5’9 and I weigh 200lbs. One is an 18.5″ frame and the other is 21″ frame. I think that according to the charts I should be fine with the 18.5″ but I am afraid I may not be comfortable on long trips. Your thoughts and suggestions?
Will
Hi Will,
Yes 18” is bigger for you. A 17” is a sweet spot for you.
Dear sir,
I am stuck in a dilemma to buy a MTB bicycle for my height (6 feet 2 inch) with inseam length of 37 inch. Since I visit my nearby decathlon store and they have XL ( ideal for 180-195cm rider height) size ROKRIDER ST 100 with 27.5 WHEELS. According to there cycling height chart, seems like it is the best buy for me but they suggest me to go for L SIZE 29er as per my height. The purpose of the ride is to go off as well on-road. Please enlighten me as I am still in confusion??
Hi Sarmor,
If you look at the bike chart you can see that your height can overlap between XL and L. It says your frame sizes are:18″ / 19″ XL, however, your sweet spot is 18”
which can also be classified under Large. SThey do have a point because wheel size can also affect bike geometry. I’d say go with their suggestion and also get a bike fit 😉
Hi – I am looking at cruisers and my measurements suggest a frame of 52 cm and I am about 5’5 and half inches. The city cruiser I am buying comes in a M (50 CM) or L (54 CM). What would you suggest I buy? The Merchant said the L frame but I am worried about the seat height flexibility I will lose in the larger frame. Not sure if its better to size down or up when you are in-between sizing.
Hi Kaleyo,
I suggest you take the medium one because it it your right size.
Im 6 foot 6 215 lbs looking to get a bike soon to put some muscle on my legs. Any suggestions?
Hi Jordan,
For your height, I suggest a 19″ + also categorized as XXL. You did not indicate if you are into MTB or Road Bike.
Hello! Can you please recommend a bike. I’m about 5’9” , 160 pounds and I’m looking for a new bike. I intend to do easy riding on regular bike trails and streets, trying to get in shape. Not sure what type of bike I should be looking for. Thank you!
Hi Teresa,
You might want to check our hybrid bike section because it seems to be the right one for you. Better get a 17″ under Large category.
Hi , I’m 6″2′ , inseam 36″, i’ve never owned an XL bike, nor have I spent more than $220 on a bike, – I’m looking into Trek bikes in size L because XL availability is difficult because of COVID, will L be fine? I’ve probably always ridden smaller M-L bikes but just ignored the fact that it wasn’t optimal size, but this is a much bigger investment.
Hi G,
Yes that falls under your size. Get something around 18” or 19”.
77.5cm * 0.70 = 54.25cm
Yet, in your chart you have 77cm listed as needing a 52cm road bike.
Why the discrepancy?
Hi M,
It is just an approximation. We understand that everyone has different body geometries. Sometimes they overlap. As long as you are still within the range in relation to your height then it is still ok. Always get a bike fit too. The frame size is just one aspect.
hi , im 5’4 , inseam 28.75 inches , just bought a Giant defy M , frame size 21 inch or 53 cm
looking the size chart on google 53 seams to be the max for y size , what do you suggest? , to get a Small size or keeep it , in long term , im gonna have a back problem ?
Thanks
Hi Juan,
You are ok with the 53cm. You can make little adjustments with the stem length. However that looks like a good size for you.
I am 5’1. Looking for a cycle. Suggest me frame size.
Hi Rashmi,
I suggest a frame size of 4’11” – 5’3″ = 13 – 15 inches; under xs category. Please get a bike fit too! 🙂
Hey Jeff — thanks so much for the article! I’m a male, 5’9″ falling right between the Trek M and L hybrid size; I can just stand over the bar of a L without much room; yet owner of the bike shop suggested a large, especially because I wanted a taller stem and slightly swept back handle bars so I could sit upright, which brings the handlebars closer to me. He said the M might not give me enough room to stand up on the pedals and still have it be stable —
Now that I got the bike, it fits pretty well as I ride it; yet wonder if a M would be better/faster/more nimble, with a bit more room over the bar, standing? Or might I be too far forward with the raised handlebars coming back toward me?
p.s. fyi, the Trek hybrid specific model I got is the FX Sport Carbon 4
thanks!
Hi Rik,
The thing is that your height overlaps between medium and large. Still, getting that frame size is ok. Yes you can make little adjustments with the handlebar and stem. Personally, a frame that is smaller is always easy to control. It feels nimble.
Hello i am 5 foot 2, and around 90-100 pounds i wanna get a mountain bike what size do i need?
Hi Izzie,
This is your chart:

hey if iim 5’4 what bike size should i get?
Hi Hiro,
You need a small frame for both Road bike and MTB.
5’3″ – 5’7″ = 15 – 16 inches
Hi

Hi GOPALAKRISHNAN,
If you are doing more road riding and light gravel then a gravel bike is for you. If you want comfort then go for a hybrid bike. If you like off raod, then go MTB.

Hey Jeff,
I am 40 years old male with height 177cm and have an inseam 81.5cm. I am looking to buy a new MTB, specifically Kona Lava Dome 29″.
I send the measurements too Kona site and they reply me to take the Medium size, but the store suggest me to buy the Large.
Which size frame should I get?
Thanks for any help
Hi Panos,
Here’s your chart:
5`5″-5`9″ 168-178 cm 26-31” 66-78 cm 16” / 17″ Medium.
I suggest you get the medium one and make little adjustments from there. You should also get a bike fit if you can.
Hi I’m 5ft 10 and I like a big bike and the bike I want only has 19” and 21” which should I go for ??
Hi Thomas,
Those are already categorized under the XL and XXL sizes. You need a large frome: 17″ / 18″ The closest is the 19″ but I suggest you better get a bike fit. And, getting a bike bigger than your recommended size can pose problems in terms of handling and comfort.
Hey Jeff,
Thanks for the detailed article about the bike fit and sizing. I am probably reading it late now since I have already bought my bike. I am 178cm tall, inseam length is 90cm. I bought orbea orca M20 with 55cm frame size and 110mm stem. I have lengthy arm span at 193cm. I would have gone for a bike fit service but no bike shop around my locality is doing bike fits now due to the pandemic. Can you please suggest what adjustments I can make to this frame to suit my body ? Thanks again
Hi Krishna,
Just a centimeter short from the range. You can make an adjustment with a longer stem length and saddle fore and aft. You can move the saddle further back.
Hi Jeff, I am 5ft tall with an inside leg seam of 68.2cm. Due to covid we are not allowed to test ride bikes and a retailer has assured me that the Gazelle CityGo C3 size D46 will be suitable but another salesperson from the same shop was not so sure. I would be most grateful for any advice.
Hi Suki,
Your sweet spot is a 14” frame. Below or beyond this would be uncomfortable.
Hi,sir.
My wife 4ft 10(148cm)
What size road bike should she get?
Hi Khai,
If you can get your wife a 47-48 cm frame then she would be ok.
I am 6 ft 2 inches and have an inseam of 33 inches not sure which size bike to get in a hybrid bike. Any thing you can suggest would help. Also what do you look for online if they don’t show measurements just says for men
Hi Scott,
Make sure you get a 18″ XL frame. This is your sweet spot.
Hello,
My 14 year old is looking at buying a used trek Gary fisher bike. He is 5’11. The bike has 29 inch tires and on the frame it reads 15.5. I have searched to get an answer to this but I think the frame may too small for him. He wants its to ride around town, neighborhood and metro park trails. But I don’t want him to buy the wrong thing. New bike owner here. Thanks for any help
Hi Andrea,
Yes the frame is smaller for him. He is going to continue to grow taller. Currently he should have 17″ / 18″ Large frame. Give him a bike thats of right size for him.
Hi Jeff, thanks so much for this post and your helpful answers to the many questions- to which I’m adding another!😉
I’m looking to get a Reise and Muller Homage ebike, but I’m unsure which frame size to get. I’m 179cm tall with an inseam of 74. There are two possible frame sizes, 49cm for body height 1.65- 1.80cm, or 54cm for 1.75- 1.90.
Any advice would be welcome, it’s an expensive bike for me and I want to get it right! Thankyou for your time.
Hi Matthew,
A large frame saize is ideal for you. 17″ is a perfect fit.
Hi Jeff-thanks for the great article! My son just bought a Trek FX 2. The bike shop put him in an XL frame (was the only one they had) My son is 16 years old, 5’11” with a 32″ inseam but only weighs 130lbs. The bike looks huge to me! The shop thinks he’ll probably grow making the L too small. What are your thoughts? My son loves the bike and says it feels good but he’s also moving up from a 1980’s era Schwinn Mt bike so any new bike would probably feel great! I just want to make sure he’s on the right bike.
Hi Honore,
Given his age, he will grow rapidly so I understand the concerns of the bike shop. His ideal frame size is 17″ which is already under the large category. If he says he feels ok with it then I think you can stop worrying.
Here’s his chart:
5`9`-6`0` 175-183 cm 27`-32` 68-81 cm 17″ L
Hey Jeff,
First of all, great article!
Secondly, I am 171 cm tall and based on the measurements on the 2nd option, I calculated my frame size as being 17” respectively. I bought a medium Giant Trance 29er MTB that has a 17” frame size but I noticed that my personal men’s “accessories” don’t have any clearance at all when I stand over the top tube. Should I downsize my bike or does the stand over not matter as much?
Thanks,
Martin
Hi Martin,
There are factors that can change the bike geometry(more common in mountain bikes) and one of them is the travel of the front suspension. For example, if the travel exceeds 100mm then it can alter the bike geometry affecting issues like top tube clearance. So far there are people with the same issue as yours and it doesn’t really affect their riding performance. Check if it gets in the way of your comfort.
Hi Jeff,
I am 6.7 and 225 pound and looking for preferable a city bike. I looked around, but it’s hard to find XL or XXL size bike which doesn’t cost $1000+. Do you might have an idea where to find these?
Hi George,
Yes you are not alone in this issue. There are issues like scarcity when you are either too short or too tall. Can you check out my post about Best Entry Level Hybrid Bikes – The TOP 10 and do let me know if this is helpful?
Hi
I am 6.3 ft tall and have 58 cm Cannondale synapse road bike.Earloer had MTB and didn’t face such issues.
Inseam 37 inches.
While riding sometimes I get right elbow pain and after resting it goes off but I am not getting it in left elbow.
Is the size correct for me or am I missing something.
Hi Vignesh,
Here’s your chart size: 6`0″-6`3″ 183-191 cm 58-59-60 cm XL
6`3″-6`6″ 191-198 cm 61-62-63 cm XXL
As you can see they can overlap but your bike is a little smaller than recommended. Your sweet spot is 61 cm. Check your saddle angle. If the angle is off, then it is pushing the weight of your body to one hand. It could also be handle bar adjustment. If it gets too much then you need to have a proper bike fit.
I am 164cm tall. and I weigh 72kg. I wish to buy a 29″ Mountain bike.
Hi Jack,
Get a 15” / 16″ which is under the small category. Get a bike fit too because when you get a 29″ it might do something to the geometry.
Hi Jeff,
I am a cycling beginner and desperately need help. I am looking to buy a women’s bike, Specialized Rockhopper 27.5, 2021. I am 164 cm tall, leg inseam 76 cm. I fall between S for body height 158 -165 cm and M for body height 162 – 178 cm. Which size would you recommend?
Thank you so much
Hi Elena,
That’s a great choice of MTB! I suggest you get the 15” / 16″ which is under the small size.
Dear Jeff
Thanks for the information. It was very kind of you. I wish you have a good day.
Hi Julia,
Always glad to help. Cheers!
Hai sir. My tall saiz 159cm…wat saiz road bike I cn buy
Hi Selvan,
A frame size around 15” / 16″ is fine for you. Those are under the small category.
Dear Jeff
What do you mean?? To choose the bike with frame size 43cm(extra small) or to choose the bike with frame size 46cm (small)?
Hi Julia,
Sorry for the confusion. I mean that you need to choose the small one and that is the 46cm.
Dear Jeff
I am 164 cm tall without shoes and 165 cm with shoes. My leg inseam is 76 cm. I would like to buy a women’s bike Trek KTM 28 Life Track. I fall between XS43 cm for body height 155 -164 cm and S46 cm for body height 165 – 169cm. Which size frame ( in cm ) should I get?
Thank you
Hi Yula,
You can choose the small frame category, somewhere between 51-52-53 cm.
My height is 5’9.what kind of bike to compatable or size for me.roadbike
Hi Sugar,
You already fall under the large category, so I suggest you get somewhere between 56-57-58 cm frame size.
Hi Jeff,
Could you please assist, i am 173.5cm tall and leg seam of 84cm – they give me different sized bikes, what is the best option for me?
Thank you!
Hi Helen,
173.5 is under the medium category.
Hi Jeff,
It would be great if you could help me. I am 65 years old female and 164cm tall. My leg inseam ia 76cm. I would like to buy one of the following bikes
1) Trekking KTM 28 Life Track with size frame 43cm ( XS )
2) Trekking KTM 28 Life One with size frame 46cm ( S )
I fall between XS and S but want to make the right choice. Which size frame ( in cm ) should I get?
Hi Julia,
Here’s your chart category:
5`1`-5`5` 155-165 cm 25-30” 63-76 cm 15” Small
Don’t get something smaller than this.
Hello Jeff,
I am 1.96 m tall with an inseam of 99 cm.
What bike size should I get?
Thanks.
Hi Guido,
For the size, check out the different charts below:
Road bike: 6`3″-6`6″ 191-198 cm 61-62-63 cm XXL
MTB: 6`1″-6`6″ 193-198 cm 29`-34` 73-86 cm 19″ + XXL
Hybrid: 6`1`-6`6` 191-198 cm 29`-34` 73-86 cm 19″ XXL
As for the kind of bike, it really depends on your riding style. Where do you want to ride?
Hi Jeff,
thanks for the information.
The plan is to get a road bike to ride during the summer months, doing some of the mountain climbs in the area where I live (British Columbia).
Finding a bike frame my size will be tricky, but I will look around.
Hi Guido,
You are welcome. Comfort should be a priority, not fashion 😉
Hi Jeff,
My length is 167cm, 45 years old and 65 kg weight. I purchased a mountain bike Scott aspect 770 small size and using it for a month. I feel a slight pain from my right lower back. Was my size selection wrong?
Hi Sijuraj,
Looking at your size chart: 5`1″-5`5″ 158-168 cm 25-30” 63-76 cm 15” / 16″ S
It looks like you are still within the right range. Try moving the saddle forward. Did you check the fork travel? You should have 100mm of travel. Beyond that will change the whole bike geometry which has an impact on comfort and position. Do let me know asap.
Hi Jeff I am 72 and I am 5′ 1 am wanting to get a bike I guess a road bike .what size should I get and how do I look on line for the right size thank you
Hi Mary,
Welcome to the world of cycling. Here is your size chart: 5`0″-5`3″ 152-160 cm 49-50 cm XS
i’m 4’11-5’0 with a 27-28 inch inseam, which size frame (in inches) should i get? Also i’m about 110 pounds.
Thank you.
Hi Lauren,
Road bike: 5`0″-5`3″ 152-160 cm 49-50 cm XS
MTB: 4`10”-5`1” 148-158 cm 24-29” 61-73 cm < 14″ XS
Hybrid: 4`10”-5`1” 147-155 cm 24-29” 61-73 cm 14” XS
Yo, considering buying Polygon Xtrada 5 sized M. Really want to get into the bigger wheels but my height is only 5’7” with 30” inseam. Worrying that it will be too up high for me. Too short for a 29er? Or it’s just a myth?
Btw, it seems to me polygon frames are on the smaller side. For example, silverback slade comp. It got somewhat similar trail geometry and numbers are close to M sized polygon.
What you can say?
Hi Daria,
Here’s your size chart: 5`5″-5`9″ 168-178 cm 26-31” 66-78 cm 16” / 17″ M
It really depends on the kind of riding you do. If you are doing light trail which is less rocky then you don’t need a bigger wheel. A bigger wheel size is also less nimble. But if you really like it then it is ok. Just don’t stray away from your recommended frame size. Other factors like saddle height and stem length can also play a big part in handling.
Hi I purchased a specialised allez road bike last year I got conflicting bike sizes from 2 different bike shops between a 56 and 54 frame.
I am 5ft 8.8 so went for the 54 frame in the end.. I am feeling a lot of pressure in my hands mainly left.. I’m now wondering if I should have gone for the 56frame but at the time 54 felt better… any ideas
Hi Lee,
You actually have the right frame size. Check your saddle tilt(this has nothing to do with the saddle height). Do some experiment by tilting the nose tip up. Do little changes until the pressure is removed from your hands.
Hey Jeff.
I am 5’10” but I have a 36″ inseam….. I keep seeing 17-18″ for taller women but my inseam is longer than the average 5’10” person… so what do you suggest
Hi Kimberli,
Yes those are the right sizes for you. You can make changes like adjusting the saddle fore and aft or saddle height. Do let me know once you have experimented with these changes.
Hi Jeff , thank for your time reading this post .
I am a 40 year old female and 158 cm tall.
What size frame in inches should I buy? I’m currently eyeing a hybrid or road bike. I am a bit confused with the size for me .
I am new in this bike 🚲 world 🌍 I think never is too late .
Hi Della,
This is your size chart:
5`0″-5`3″ 152-160 cm 49-50 cm XS. I would recommend you also get a bike fit.
I am 5’0” inseam is 29” what size of ebike do I need
Hi Teresa,
Welcome to Bicycle Guider! You did not indicate what type of ebike you like. However, I will list down these charts for you:
MTB: 14″ XS
Road ebike: 49-50 cm XS
City bike/Hybrid: 14” XS
Hi,
I’m 6feet 2 inches tall. My inseam is 33. I’m 65 with pretty bad knees.
I would like to buy one of those electric mountain bikes with very FAT tires. I will be riding mostly on uneven roads, gravel and sand filled roads, actual low incline mountains. I will ride for leisure only.
What would you recommend? Bike size, frame size? All the works. My first time to buy a bike. Really.
Hi Mr. Collins,
You’re on the taller end of your category so I would suggest a 19″ frame unless you intend to get one with front suspension you may consider going down to an 18″ frame.
I am 5′ 1″ tall with a 29″ inseam. Would a 44 cm Mercier Elle be too small for me?
Hi Eileen,
Yes that is too small. Look for 49-50 cm frame. Cheers!
Hi Jeff,
It’s amazing how many people you have responded to and helped with this confusing aspect of bike buying, especially during these times of online buying! It would be great if you could help me with this too!
So I’m 177cm tall, pretty flexible and my leg inseam is 83cm. I’m going for a pinnacle arkose 3 https://www.evanscycles.com/brand/pinnacle/arkose-3-2021-gravel-bike-915761. I fall between M and L but want to make the right choice. Any help would be very much appreciated!
Hi Eric,
Your bike frame falls under the large category. Your sweet spot falls somewhere here: 56-57-58 cm. Yes that’s a good gravel bike.
Jeff, this is a great resource. Thank you!
Do you have advice: I am a 5’10” female, with a 34.5″/87cm inseam, and longish arms with a shorter torso (yep, all limbs).
Your charts show a road bike for me is 61cm, or 56-58cm, or 58cm.
Do I get a 58cm, and extend the handlebars with a longer stem to make up for my shorter torso?
Thanks for your help!
Hi Leigh,
Yes that sounds like a good idea. After all, you are still within the size range.
Hi Jeff, thanks for the informative article. I am 5’3 (160cm), and am planning to buy a Polygon Cascade 3. Would a Small or Medium frame be a better buy /fit? Thanks!
Hi Cheryl,
One with 15” / 16″ under the small category is good enough for you. That’s a good brand. The 100mm front suspension is adequate for any off road/gravel experience.
Btw road bike
I am an interesting fit, i think. I am 5’8 inches tall, and have a 33″ inseam. The inseam seems like a liv large will do, but my height seems medium. https://www.sefiles.net/images/library/features/avail-3-sizing.PNG
Hi Judy,
Yes sometime they do overlap because we have different body geometries. I’d say that you stick with the medium frame and so incremental adjustments from there. These adjustments can be about saddle angle,fore & aft, saddle height and also stem length. And get a proper bike fit if you can 🙂
Hi Jeff, I am a little bit confused. I am a male 171cm in height with an inseam height of 77cm.
I want to buy a specific bike that has a size calculator. According to it I must have a 50cm Small bike.
However according to your charts it seems I have to buy a 54cm or Medium bike.
The problem is that there is no availability to the store to test drive it….
What should I do?
Here is the link of the bike where the size calculator is
https://www.cube.eu/uk/2021/e-bikes/city-tour/on-road/touring-hybrid/cube-touring-hybrid-one-400-bluengreen/
Am I doing something wrong? Which size do you think I should get on the specific bike?
Hi George,
There is really no “accurate” or “perfect’ chart for all due to our physical differences. However, as long as we fall within the range then we can make little changes in terms of stem length, saddle fore/aft, saddle angle and seatpost height.
For hybrid and touring bikes, here’s the chart:
5`5`-5`9` 165-175 cm 26-31” 66-78 cm 16” Medium
Hi Jeff! Thanks for your excellent inputs. I’m 184 cm, male, weighing 92 kg. I rode a mountain bike a few years ago (very little) and would like to get serious about it. Is it alright for me to get into a road bike directly or should I go through with a hybrid first? Also, your advanced chart tells me that I need to go for a 58 cm XL bike. Is that ok for a beginner like me too?
Hi Hector,
There are things that you need to note when switching from MTB to road bike:
1. Road bike demands more body flexibility as the position is not relaxed or upright compared to MTB. You need to take note of this as it’s been a while since you’ve been on a bike based on what you said.
2. You will feel every bumps and inconsistencies of the road when you ride a road bike.
3.I suggest to you try borrowing a road bike and then go for a spin. You will realize something along the way. Don’t buy one yet before you are sure that it’s the kind of route you want to go.
4. This goes for buying a hybrid. Test it first.
Yes the chart is right. That’s your size.
Hi, I’m 5.5 inch tall order a Polygon Cascade 4 Sport MTB and it’s size 18″” (Medium).
Please tell me, Is it good to go or should buy small version (16″”) ?
Hi Anand,
Ys medium is the way to go. That’s your size.
My son is 5’6 32.5 inseam and wants mountain bike. What would you suggest please?🙏
Hi Diana,
He is within the medium range. Here’s his size chart:
5`5″-5`9″ 168-178 cm 26-31” 66-78 cm 16” / 17″ Medium
Hey there, i got a road bike aero type size 48 (168-175) factory said it suit me bcz my heiht 168cm + 78.3cm inseam. The smaller one 46 (x – 168) so i decided to take the 48 size. But i feel somthing uncomfy with it my wrist kinda hurt especially right hand. I thought maybe my reach its too long for me 48 + 100mm stem within. But my calculator and ur table above result its frame recommendation for me is 51(ETT 56 +90mm stem). How explanation with this, my 48 make me think its too long, but how 51 will suit me up? Where do i find something unusual in this my current frame itself or my perspective. Thanks
Hi Giwan,
Did you really check our chart? Here’s our road bike chart. Our recommendations are pretty standard
:5`6″-5`9″ 168-175 cm 54-55 cm Medium
Now if your wrist is hurting it is something to do with your saddle angle. If the nose is facing down, it will push your body weight to the handlebars and it will cause pain. Make sure the saddle is level.
I am around 5’8, is it possible for me to ride a 50 size bike?
I want to buy a city e-bike, my height is around 5’8 and 75 kg.
will you kindly check the link below and will you recommend me if it is okay to buy the bike?
https://www.itek-webwinkel.be/elektrische-damesfietsen/11762-elektrische-fiets-constancy-36v-8719636003072.html
will you give me your suggestions too.
Thank you for your cooperation.
Hi Delelegne,
Here’s your chart: 5`5`-5`9` 165-175 cm 26-31” 66-78 cm 16” M
That’s one attractive bike. I also suggest you get a bike fit to insure that you are going to be comfortable all the way, riding it.
If you mean 50cm frame then no. That’s an xs and will feel uncomfortable.
Im a 5’10.5 male. My friend is selling his specialized hybrid. It has a 19” frame. Will that work for my height?
Hi Aaron,
Here’s your chart: 5`9″-6`0″ 178-185 cm 27`-32` 68-81 cm 17″ / 18″ L
That’s an XL. It might create issues in the future.
Ok, Thanks Jeff. May I know what type of issues I could run into? I don’t know a lot about bikes.
Well, one of the issues you might encounter with poor bike fit is lower back pain. I am saying this not just from people who have experienced similar problems; but also from personal experience. A more oversized frame will make you stretch your hands and body, making it strain. You might also have issues with control. A bike that fits you properly will feel handy and easy to maneuver. These are the few things that worry me when it comes to improper bike fit. There are certain adjustments: lowering the saddle, shortening the stem, and adjusting the handlebar angle. But this does not guarantee that you will feel comfortable. Although, I must say that no two people have the same body shape or geometry. Some bikes will not fit on a person of the same height(longer torso vs. shorter legs and vice versa) but will be ok with another.
Hi I am looking for a bike for myself and my husband. I’m 5 11 and have an inside leg of 33 and my hubby is 510 with an inside leg 29 can you advise what size of tire and frame we should get?
Hi Lorraine,
Here’s your chart: 5`9″-6`0″ 178-185 cm 27`-32` 68-81 cm 17″ / 18″ L
Are you getting a hybrid, a road bike or an MTB?
For MTB you can get a 27.5
for Hybrid, it’s 700c and the thickness should be 35mm is you are into commuting.
? I’m 5’9 and looking to buy a bike. What size do I need?
Hi Cat,
My question is, what kind of bike would you like? MTB, City Bike, Road BIke or Cruiser? Generally you will be ok with a 16 – 17″ frame size(medium).
I’m a 6’4” man; What TIRE size goes with a 24” mountain bike frame?
Hi Gatis
A 29″ is a perfect tire size, not just in terms of your capacity but also for aesthetic reasons 😉
Hi Jeff! Thanks for the article!
I have a unique problem in that one of my legs is shorter than the other by a centimeter or two. I’m 5’3″ otherwise but how would I determine what size I need?
And for some reason i’ve seen either 5’3″ need a bike that’s 18 or 26. Why is this? Is it because of my gender (female)?
Thanks so much!
p.s. I’m looking for more of a cruiser bike. It does need to do hills a bit but I favor more of the retro look and I’ll mostly be riding it around town.
Hi Robin,
Cruisers are the trend these days. With the explosion of local bike cafes, you are on the right track. Do check my article about Electra Townie Cruiser Review
Hi Robin,
A 15″ or 16″ frame size is good for you. I’d recommend the 15″ for allowance. You can also lower down the saddle a little bit. 26″ would refer to tire size I think, and not the frame size.
Hi. I’m buying my first new road bike. I’m looking at a Planet X Spitfire. I’m 5′ 6″ with a 29.5 inside leg. What size should I be looking at?
H Chris,
Get a 54-55 cm size:Medium
Hi Jeff ,
I haven’t rode a bicycle for years, but would like to get back into it, I am 5” 9” tall and have an inside leg measurement of 34” am looking at a Merax Finiss bike as it has suspension, but haven’t got a clue regarding the size i need, either frame or wheel.
It used to be just wheel size, but all changed from penny farthings now, would you be kind enough to advise please
Thanks
Hi Peter,
I’d recommend a frame of 17″ / 18″ which is under the large category. 17.5″ is not a bad size. If you want to go smoother on rocky surface then a 29″ is ideal. Yeah there are many wheel sizes nowadays it’s amazing.
Hi my name is alan.
My high 6. 3 190 cn.
What is right size bike thanks
Hi Alan. You better get a 18″ / 19″ under the XL category. Cheers!
Hi my names Jo, am female and looking at a womens 17.5 cm bike and I am 186cm tall. Should be comfortable?
Hi Jo,
Yes, a 17.5 cm bike should be within your size range.
Hi there,
I am a 40 year old female and 157cm tall. What size frame in inches should I buy? I’m currently eyeing a 26″ mountain bike 21 speed.
Hi Delia,
You should get a 15” / 16″ size MTB. This is under the “small” category. 26″ offers responsive navigation.
Hi Jeff, I’m 174cm weighing 198 pounds, inseam 81cm. Planning to buy Trek Marlin 7 “Medium” since size “M/L” is out of stock. Will Medium size be okay for me or do I wait for M/L.
Hi Sudipto,
Just my suggestion, it is better to wait and get the right size for you than venture into something that will cause you discomfort or even injury. Yes get a medium 16” / 17″.
I’m completely confused lol my daughter and I wish to purchase Mountain bikes – I am 5ft5 and she is 5ft 1 – what size frame should I be buying for us both… help !!
Hi Lynne,
You can both get a 15” / 16″ under ‘small’ category.
Hello… what size do you recommend for a 6’8” man?
Hi Seana,
For anyone taller than 6’4 that’s 21+ inches frame size.
Hi Jeff,
Great article. Ordered the Triban RC 120 as my first road bike in Size XL. I am 6’3, inseam 35 and weigh 220 pounds. Just checkin this is the right size for me, correct? Because i fall in the measurement from Decathlon a bit in between L (height 180-190 cm) and XL (height 190-200). In cm i am 191, and i read so much that they advice the smaller one. But i want a comfortable ride instead of agressive.
Thanks in advance!
Greetings, Job
Hi Job,
Sizes recommendations do overlap. Here’s your chart:
6`0″-6`3″ 183-191 cm 58-59-60 cm XL
6`3″-6`6″ 191-198 cm 61-62-63 cm XXL
So you still got the right size but not lower than 60 cm. You can do something with the length of the stem but that’s it.
I am 169cm tall. and I weigh 70kg. I wish to buy a 29″ Mountain bike. Please advise.
Hi Grant,
Yes a 29″ but with the frame size(s) of 16” / 17″ under the Medium category.
Hi Jeff I’m 6 foot 4 Inches in hight and my partner bought me a mountain bike but I think the fame is on a 26 inch.. What síze should I be using..
Hi Mark,
XXL will suite you best. That’s a 19+ frame size by the way.
5’11 M 31″ inseam
What size gravel bike would I need?
Already have a large xc bike and it seems a bit large.
Hi Jason,
Be sure to get a large one. That’s around 56-57-58 cm frame. Enjoy!
Hi, my height is 177cm and I’m planning on buying a 29er. Is that a good one or 27er would do? Thanks!
Hi Christian,
Based on your height, you need a frame size around 16” / 17″ under the medium category. It is really up to your riding preference. 29″ is bigger and will run smoother on gnarly paths like rock gardens etc. However, a 27″ would be easy to maneuver and is more responsive than the former.
Hi Jeff,
I am looking at getting a new hybrid, the one I like comes in a 15″ or 17″.
I am only 5’4″ but have an inseam of 76cm. I have had a 16″ in the past and it has always felt to on the small side. Do you think the 17″ will be too big?
I have used a larger bike before, I’m not sure what size exactly, which felt ok but I am looking to use this bike more often and want to insure I’m getting the right size. Unfortunately the stores around me are only open for click and collect so I cannot go in get any advise.
What do you suggest?
Thank you in advance for your help.
Hi Charlotte,
Based on your height, your old bike has your ideal size. I suggest you stick to that one, or a 15”. 17″ will be too big.
Hi I am 175cm and my leg inseam 81cm can I ride a 52 bike
Hi Med,
Are you talking about a road bike? If that’s so then this is your size category: 5`9″-6`0″ 175-183 cm 56-57-58 cm L so the answer is no.
I am 6 ft and have a 87 cm inseam
Would a 58 cm road bike best ?
I have a 59 cm now and am buying a second bike.
Hi Gary,
Here’s your chart: 6`0″-6`3″ 183-191 cm 58-59-60 cm XL
Although I would also suggest a bike fit.
I am going to buy Salsa Fargo. I am 185cm high and inseam 87cm. Will L be the right choice?
Hi Adam,
That’s a good brand! Their bikes are very popular now, with the bikepacking and bike touring fans. Here’s your chart: 6`0″-6`3″ 183-191 cm 58-59-60 cm = XL . You need a slightly bigger one for your size.
Hello. Can I get a decent mountain bike under 400 dollars ?
Family rides on the road but definitely want to hit the trails as well.
I’m 6ft1 .
Hi Lott,
Check out my article about Cheap Mountain Bikes Of 2020 You’ll find something there! Cheers!
I am 6’2″ and recently changed from a 58CM road bike to a 56cm bike. According to the chart I should probably be on a 56 but it feels too small. I had to extend the headset and move the seat back. It helped a little, but when i am stopped at a light my foot prevents the turning of the wheel cause my shoe sticks out past the rear of the Front wheel.
Is this common in the stopped position to be touching the front wheel with the up pedal foot?
Hi Darrell,
Yes this is a common thing among race bikes to have this issue. It is not something that you should be alarmed.
Hey,
I’m a bit confused. My height is 183cm and inseam 83cm. I’m going to buy Orbea ORCA and according to their sizing chart I need 53 frame size, however according to your chart I need 56. Orbea doesn’t have 56, there is either 53 or 55 frame size. Can you give me and advice what size should I choose?
Hi Roman,
Are you sure you are looking at the right chart? This is your category:
5`9″-6`0″ 175-183 cm 56-57-58 cm L
6`0″-6`3″ 183-191 cm 58-59-60 cm XL
Jeff, yes I am. Take a look yourself – https://www.orbea.com/ua-en/calculate-size/popup/road/ORCA_RAN18/
Choose Man – 183 – 83
Hi Roman,
This is a hybrid/city bike measurement and not for the standard road chart.
6`0`-6`3` 183-191 cm 28`-33` 71-83 cm 18″ XL
So yes their website is correct for that category 😉 Cheers!
Hi!
I purchased a men’s (I’m a woman) diamondback wildwood (city/hybrid/comfort) bike several years ago and have just decided to start riding it. I am 5’4 and the frame is 17”. I feel comfortable on it, but should I consider purchasing another bike in a small (15”) size frame? Thanks in advance!
Hi Tia,
A 17″ frame is bigger for your size(even though you feel comfortable on it). I think that if you can upgrade to a new bike, have a suitable on that suits your size. Yes a 15″ should be perfect.
hi sir jeff im 169cm but my inseam is 73cm
what size of top tube and seat tube do i get for my road bike
Hi Christian,
Here’s your size chart: 5`6″-5`9″ ft (168-175 cm) frame size between: 54-55 cm Medium
I am 5’2” what size wheel should i ride
Hi Rick,
In cycling, it’s frame size that really matters. For you, 13″ to 15″ should be comfortable. 26″ would be easy to navigate.
Hey Jeff, I’m 6’3 but only 14. I’m looking into a new downhill bike, most likely a YT tues pro. I would like to know if I should get a large frame or XL.
Thanks
Hi Parker,
You better get a 19″ + (XXL) because you will be uncomfortable on large and XL frame. Get a proper bike fit too. Cheers!
Hey Jeff, thank you very much for such an informative website! I can feel your passion by your frequent update to your articles. I also enjoy the very first picture of this article. 😀
A question here, though. This article mentions many methods, which sounds great, but then what is the single source of truth?
For example, my leg inseam is 29 inches (=74cm), the method 2 suggests that my city bike should have 0.685*inseam = 20 inches (=51cm) frame (which happens to be very close to the example you gave in method 2 already). But then, method 3 table 2 gave a “leg inseam 26~31 inches -> frame 16 inches” or “leg inseam 27~32 -> frame 17 inches”, those are noticeably smaller than the result of method 2. Which one should I trust?
All that being said, is it true that, based on the theory of maintaining that “nice bend on the knee”, one should aim to find a frame such that “lowest seat height – lowest pedal height = inseam – several inches”?
Hi Ray,
To answer your question Philosophically, the best source of truth is your own body. That means there is no ‘one size fits all’ even when we use the charts. All categorical sizes overlaps and a centimeter can make a difference in your comfort. If the bike is too big for you, then you can make adjustments in seatpost fore and aft or height. You can also make little adjustments on the stem length. So my method:
1. Look for the frame size closet to your body size
2. Do a bike fit and make incremental changes based on those things I have mentioned.
3. Listen to your body. If you are too particular in the math you might forget the fact that we all have different body structures(longer torso/shorter legs etc).
Hi Jeff regarding to my last comment I’m looking to buy a mountainbike frame but again the only size is XS and my height is 165cm and my best frame size is S should i buy the extra small?
Hi Alfonso,
No, get the small one. You are under small but you are also near the Medium category.
Hi Jeff, thank you for the revert as you suggested to go for a smallest one but on that one her knees are bending ..and as per her inseam size 20 size wheel is suggested .though I find it a little bigger for her age but she is able to peddle .m totally confused ! Can you help .
Hi Seema,
Ah ok thanks for adding that info. Indeed there are situations like that. How about this: you can get the 20 but also try to lower the seatpost. That would make it easier. Let me know about the update.
Hi Jeff , my girl is appx 110-112 cm of height age 6 yrs and inseam size is appx 22 inches .should I go for a 16t or 20t size for her as 18t doesn’t come in kids range ( this is what I have been told by the dealers ) An early revert would be highly appreciated !
Thanks
Seema
Hi Seema,
Go for the smallest as they are suited for her age.
Hi Jeff my height is around 165cm and im looking to buy a new bike frame but the only available is XS should i buy it or not? All of the outer sizes are not available anywhere
Hi Alfonso,
Below are the ranges that are suited for you(Small) supposing you are going for a different kind of bike:
City Bike/Hybrid:63-76 cm 15” S
Road Bike: 51-52-53 cm S
Mountain Bike: 63-76 cm 15” / 16″ S
Hi Jeff
I need a road bike for me. My height is 177cm and my inside leg is around 79cm-81cm. Right now i can buy FOCUS bike size L but I don’t know if I have to go with M or maybe witch frame size? 52? 54?
Thank you!
Hi Jaka,
I suggest you go with Large as it is your size range.
Here it is: 5`9″-6`0″ 175-183 cm 56-57-58 cm L
Your methods are really easy to choose a perfect size bicycle.
Hi Rakib,
Thanks. It is my intention to make a bicycle rider feel comfortable.
Hello Jeff, my height is 165cm and my inseam is 78cm. I want to buy a Trek Domane road bike. According to your website, my frame size will be 52cm, but at my nearest Trek store, the 54cm frame size is only available. If I need the 52cm one, I will have to wait till March 2021. I have checked the road bike at the store and I could easily stand over the bike with enough clearance from the top tube. Shall I purchase it?
Hi Tonmoy,
You are size Small and the only available bike is a Medium. Clearance while standing is not only the thing to consider. You have to think of the reach when you grip the handlebars. This can be adjusted by stem length, saddle fore & aft etc. It is up to you but you need to think of comfort especially during long rides.
Awesome article Jeff, and so cool to see your responses to questions! Hope you can help us too. My son has outgrown his old hardtail so we’re looking for a replacement. He is 161cm tall with 77cm inseam, which puts him in both the small and medium frame sizes. Given he’s growing fast, and has such long legs, would you recommend the medium size or go with the small? Thanks in advance for taking the time to help us!
Hi Vicki,
That is a tricky question. Is he going to use the same bike for quite a while? You can get the size that’s recommended for him and then perhaps have it replaces after a year or two. I am thinking along the lines of comfort and stability.
Hi,
Looking at your different options, for me to have a road favouring hybrid, I would need a 20″ frame by my height, 6’3, or 21″ by inside leg (31.5″). But, your later chart suggests 19″.
Is it therefore best to go for 19″ and raise the saddle (is that what is meant by lengthening the stem?)? If so, should I then raise handle bars with spacers as well, potentially?
Your time and patience in responding would be greatly appreciated.
Hi Simon,
Yes they do overlap and indeed sizing can be complicated. Yes to all your suggestions. Don’t forget stem length 😉
Hi,
Need a bicycle for fitness, my height is 5’10”, and weight is 90kg. Am looking fatty,can anyone suggest me which kind of bicycle is suitable for me.
Hi MD,
Fat bikes are exciting. You can check out my post about it. You can also see if a cruiser is something you would consider. I also suggest you get a 17″ frame size which is under the large category.
Hi, Jeff, thanks so much for this post! I am shopping for a new bike and keep coming back to this article for reference.
I’m torn between an S3 and an S4 (M and L, essentially) mountain bike. I rode my brother’s large a few weeks ago and it felt a bit unwieldy (big, hard to turn) in the tight single track turns but was felt comfortable otherwise. This weekend I bought an S3 2021 Stumpjumper and it feels a bit small (front to back), except in the tight turns. (My brother’s bike is a L 2019 Stumpjumper carbon, mine is new but alloy–they changed the size labels since he bought his.) I’m torn!
I only have about a half-inch left to move the seat back. Sunday’s ride (the only one on my new bike) was mostly sidewalks because the trails were too wet. I had a hard time getting comfortable and felt like I needed more “space” from my seat to my shoulders/hands. I also felt like the seat could have been a touch higher, though it was objectively fit to the right height before we started.
I have an unusually long torso for my height (5’8″) but can’t find any metrics on using torso height and arm length to determine size. All of the other charts are slotting me into an S3 (leg length, height, ankle height, lower leg length, etc.).
Any suggestions?? I’ve tried contacting the shop, and Specialized, but as I’m sure you know their phones are all busy and I only have until Saturday to return this one if it’s the wrong size. Also, the more opinions, the better right now! Thanks so much!!
Hi Elizabeth,
That’s not a problem. There are times when sizes overlap. I suggest you go for the stem length. If the bike feels too big, shorten the stem. If it feels too short, lengthen the step. But word of caution: make incremental changes in centimeters.
Hi this is Rohit and my height is 6 feet 3 inches, please suggest me proper size in hybrid bike.
Thank you
Hi Rohit,
That’s easy. You look for 18″ XL.
Hello,
My height is 179cm, leg inseam – 87cm.
Looking by height I should choose 17″ frame for mountain bike, by inseam – 21″
Which measurement is more accurate?
Or I should go for something between 17″ and 21″?
HI GV,
Go for the 17″. That is within your range. If anything feels to big or too short, make an adjustment on the stem length.
Hi Jeff, i am 5’6 (167cm) my inseem is 31 inch (79cm) which fixie bike i need? In my place only two frame sizes are available. M46cm and L53cm. These fixie bikes are said to be designed in England. should i purchase any of these or refrain from both and look for another brand/make?
Hi Prathima,
Fixies are still road bikes after all. You look for 54-55 cm or Medium frame size. These are way too small. I would prefer you look for something you can test or have a bike fit. If not, then go for something that has your frame size rance.
Hi, I’m getting a city bike my height is 176cm and 52-53kg and my legs are way longer than my torso what bike size is the best for me
Hi Lumantam,
Look for 17″ under the Large category.
Hi, I’m 5’2 should I get a 15.5-29er or a 17-27.5? Thanks!
Hi Xaris,
Get a 15.5 .It is under your range.
Hi Jeff ,
I am 1.65m height , 62.7kgs weight , 76cm leg inseam . May I know what mountain bike frame size suits me? Thanks in advance .
Hi Sunny,
Look for 15” / 16″ frame sizes. These are under the small category.
I just bought a bike xs. The guy in shop said its a good size yet I’m 5ft 4in . What should I do?
Hi Angela,
I think you should return it. You need a 15” frame size or small.
Thanks for the post! Shopping for my young teen. Currently 5’5” inseam 30.5” but growing fast! Looking for sizing and hybrid bike recos!
Hi JT,
A 16″ Medium is the right size. Cheers!
4 foot and 11 inch tall female and need to know the right size bike for me. Please help
Hi Daniel,
As long as you don’t go beyond the 13 – 15 inches frame size range you will be ok.
Hi im 6,2 with 88kg what bike size should i get?
Hi Herbert,
As long as you stay between the 19 – 21 inches frame range you will be ok.
What is the best MTB for me my height is 5’6ft and my weight is 147 lbs?
Hi Sergie,
As long as you stick within the 15 – 16 inches range you will be ok. That’s Small by the way.
I am 5’7, and 115 kg, what MTB fitted to me? L or M, and can 27.5er handle my weight? or should I go to 29er?
Hi Matt,
You belong to the “Medium” category. Yes a 27.5er can handle your weight. A 29er will run smoother on rock gardens.
I’m the luckiest one 🙂 15” frame for a mountain bike feels so uncomfortable for me, and 16” seems a bit big. How can it be? “D
Hi Lana,
A cm can make a difference and your situation is normal. Try to make adjustments with the stem length(get longer or shorter one) and I tell you the change is dramatic.
Hey! That’s such an exhaustive post. I’m 177 cms and weigh 116 kgs and have a large frame. I’ve booked the Btwin Rockrider ST100. 27.5cm tyres, XL size (suited for 180-195 cms) Should I cancel?
Hi Aseem,
Yes, centimeters can make a difference in comfort and handling. I suggest you get a frame size suited for your height.
Great article
Im 176cm tall
78.75 inseam
Going from a BMC roadmachine in a 54, to a Tarmac SL7. I think the bikes will be way different but while i want the more aggressive position i also would like to make sure im not too stretched. Ive ordered the tarmac frame in a 54, which comes with a 100mm stem. should i consider a 52? Or stick with 54 and adjust seat, stem as needed?
Hi Ryan,
You fall under the Large category and your size ranges are: 56-57-58 cm. 54cm is medium which is a little bit smaller for you.
Hi, I’m thinking of buying a Hybrid and not sure if I should get a XS or small. I’m 5’3.
Hi Kimberly,
A 15” is perfect for you. This is categorized under small. Do check out my post about the Best Entry Level Hybrid Bikes – The TOP 9
Hi. This article is awesome, has made things make more sense to me.
Any advice on what I should go for with an 86 cm inseam, 198 cm tall and about 130 kg weight? I know how to cycle, but never was into it. But now I am a daddy and my son is 4, loves his bikes rides and I don’t love the running after him no more. Need a bike for casual bike rides in the park with him. Maybe off road as well. Any suggestions please?
Hi James,
You are quite tall so I’s suggest you get a frame size that’s 19″ under the XXL category. If you love both road and offroad riding then getting a hybrid bike is a good choice.
Hi，I”m 5’8′ tall, going to take my new MTB.
Isn’t 17′ frame size I can make it?
And isn’t 27.5″ is too hard for me, or 26″ is better choice?
Hi Jack,
17″ is perfect and it still falls under the ‘medium’ category. 27.5″ is just right. 26″ is too small imho.
Hi, i’m 5’2 and 73kg not know how to ride a bike til now 🤣 planning to get my first bike. When i asked the sales man he showed me the kiddie size ☹️ For me. Im confused of bike sizing
Hi Sier,
A 13 – 15 inches frame is suitable for your height. These are under the small category.
So I’m not sure I did a good job of explaining my question. I want to buy a used women’s modelDiamondback AirÉn two, 50 cm. I’m a male, 5′ 8 3/8″ tall, with really short legs, 28″ to 28.5″. The formula inseam X .7 for a road bike gives me right around 50 cm for my size, whereas my height would tell me I needed a larger frame, 52 to 54 cm. What do you think? If necessary, I could get a lay back seat post. Thanks again. I’ve really enjoyed reading all this info.
Hi Bill, I understand what you mean. Your height belong to the medium category with recommended frame sizes of 16 – 17 inches. That still translate to the same category for road bike but we have unique body builds so your legs might also need a smaller frame size. A layback saddle and a longer stem would help this. Also please have a bike fit that way you can explain your situation and have these problems solved.
Hi Jeff,
I’m 5’8” with 29” inseam. Was able to obtain Cervello P3 triathlon bike that is 56 cm
Is it worthwhile to get a professional fitting? Or is the bike just too big. Very helpful article
Hi John,
56 is still within your range but a bike fit will improve comfort in terms of finding the right saddle angle and stem length. Do get one. Cheers!
Hi, I am 5’4.5” tall. I am considering buying a 21-speed bike from a friend. It’s 26”. Is that a good size? I am so confused 🤷🏼♀️… I want to enjoy my ride for exercise and movement.
Hi Sol,
16″ is ok for your height but please test the bike first. Also get the frame size. Your recommended frame sizes are 15 – 16 inches.
Hi Jeff – Many, many thanks for this great article! This is so helpful!
I am looking to get a secondhand road bike. It’s 16 in with 27.5″ tires and I’m only 4’11”.
If it’s too big, do you think a shorter stem will help to make it fit better?
Thanks in advance!
Hi Annabel,
For your height, the bike size should be 13 – 15 inches. That roughly translates between 47-48-49 cm range or XXS. You can shorten the stem but there will be an effect in handling. I suggest you get a proper bike fit.
Hi, this article is so helpful. I am a beginner. My height is 5’5. What size of MTB is suitable for me to buy?
Hi Norliza,
Welcome to the world of MTB! You will be ok with 16” or 17″ medium size frame.
Hello, I’ve found a “Road” bike I really like but it’s only available in a 55.5 cm frame. I’m 6ft 1 and a smidge, not quite 6.2. My inseem if I’ve measured it correctly is showing at roughly 83.7 cm.
Will this 55.5 cm frame bike be suitable for me?
Thanks
Hi Christopher,
The bike is medium size. You are bordering on the XL category. Although you can make some changes ike buying a layback seatpost and getting a longer stem, there will still be a noticeable odd feeling in terms of handling. You should be ok with frame sizes 58-59-60 cm.
Hi, Nice post. I’m 179cm tall (in between size M and L) so I don’t know if I have to go with M or L. I don’t have my inseam measure right now :/ What size you recommend?
Hi Davids,
Go with the large one.
Hi Jeff, this article is super helpful! I just need some final confirmation if you could help, that would be much appreciated!
I’m torn between a very good 53cm Wilier and a good 56cm Cervelo. I’m 183cm/6’0″ tall and my inseam is 83cm/32″ and a bit. The seller insists that with a few adjustments (stem, seat, spacers), the 53cm Wilier will fit perfectly, whereas my heart tells me that the Cervelo even if it’s a bit older could fit me well without adjustments. Do you think the adjusted 53cm could work for someone with my dimensions? Thanks!
Hi Laith,
You overlap between L and XL. 53 is already small so even if you make adjustments it will still affect your handling. I’d say go with the larger bike.
Hi Jeff, this article is so informative. I’m a 32 year old weighing 95KGs, could you help me out choosing the right frame size & tire size?
Thanks in advance.
Hi Nir,
I would be glad to. What’s your height/inseam? What type of bike do you want?
Hello. I have just hired a Swapfeit bike for a long time, it should be a city bike I believe. My question for you is: does the size of the wheels matter and/or does it have anything to do witht the frame size? I have always used a mountain bike in the past, with smaller wheels than this, and it was more comfortable, not sure it’s just because I have to get used. I have used this bike today and there is something uncomfortable in riding it, from a first look seems that the wheels are too huge for one of my height (160cm). Could you please tell me if wheels diameter needs to be no greater than a certain number, considered my height? Thanks
Hi Tiziana,
The most important thing to consider is frame size. The wheel is secondary. I would suggest you get a small frame. A 24″ cruiser tire will feel comfortable.
I’m 6’2 , 250 pounds and don’t know what bike size I need? Help?
Hi Robert,
Are you riding a road bike or a mountain bike? For road bikes you fall under the 8-59-60 cm XL category. For MTB, get a 18″ / 19″ XL frame size. Oh, and don’t forget to get a proper bike fit.
Hi Jeff,
I am so far riding with MTB and now want to change to a road bike, hoping to to long distance. my height is 5′ 4″, what is the best suitable road bike for me.
Hi Dimuth,
You fall under the “small” frame size category. A 52-53 cm is your sweet spot.
thanks for sharing the list of Bicycle it can very helpful for me to choose the best cycle for my kid.

What have you been up to? I am fascinated about covid19. Can you talk about it? If the same thread is opened please redirect my post :). Thanks :).
PS: I don’t know any people with covid and you? rambo 😀
Hi Rambo,
I posted a lengthy article about that in this link. There is another post about cycling in the time of coronavirus here.

Good day, I’m 5’10.5″ inseam of 33″, tried a 58 it felt like I was stretched a bit and the 56 felt more comfortable, guy says go with 58, initial thought was 56 more comfortable. I’m used to riding a hybrid type, more upright. What say you?
Hi Carl,
Your bike size belong to the Large category with sizes 56-57-58 cm. Choose what feels comfortable to you. A cm can make a difference.
for someone who is 5’3-5-4′, does wheel size matter? I am interested in getting the Schwinn hybrid bike but I’m concerned it’s a 16″ frame and a 28″ wheel? Here’s a link with an example: https://buyingatbest.com/products/schwinn-discover-womens-hybrid-bike-700c-wheelswhite28
hi WnC,
Yes, 16″ is your sweet spot. I think you will enjoy the riding experience. Go for it!
Hi Jeff,
Thank you for a great article. I’m looking at purchasing my first road bike (a Specialized Allez Elite) but I’m wondering on the size. I’m 171cm with a 30 inch inseam and they have both a 52 and 54 in store. I’m right in between the two sizes. I’m leaning toward the 52 so I can raise the saddle and/or handlebars to find a good fit rather than not having the ability to do that if the 54 proves to be too big.
What would you recommend?
Hi Adam,
You fall within the medium range with recommended sizes of 54-55 cm. Sometimes the body adapts to whatever size it is used to. If the 54 proves to be too big, maybe you can lower the saddle a bit? Let me know what you think.
Hello, I have a vintage mercier colombus 55ctc or 57 ctt. I am 1.83 cm and my instead is 83cm. I feel it a bit short. I increased the stem from 9.00 to 11.00 cm and I feel better but again something seems to go wrong.
Hi Alexander,
That’s a pretty looking bike! You belong to the 56-57-58 cm size range(Large).Your sweet spot is 58 cm. So yes it is a bit short. You will definitely feel it as it is a wrong size for you.
Hello, I have a vintage mercier colombus 55ctc or 57 ctt. I am 1.83 cm and my instead is 83cm. I feel it a bit short. I increased the stem from 9.00 to 11.00 cm and I feel better but again something seems to go wrong. Any recommendations? Thank you.
Can you try to raise the saddle height? Or maybe buy a layback saddle.
Hello,
I’m 6’5″ and someone is selling a 29″ road bike. Is it large enough for me?
Hi Jason
A category you should take note is the frame size. You belong to the XXL category with frames ranging from 61-62-63 cm.
Hi, very nice website, especially for me who am considering buying a gravel bike right now
I am 5.6″ (1.69cm) and thinking to buy a Jamis Renegade A1 51cm. Is this a good size or is it small?
Thanks for the content.
Hi Atila,
For 5’6″ you need a frame size between 54-55 cm. 51 is too small.
I am looking for a road bike for indoor use (i.e. zwift, etc). I am 5’2″, 125 pounds with 28.5″ inseam. Since it is strictly for indoor use, i am just looking for entry-level road bike types. I’ve seen Vilano bikes, are they any good? Any other bikes you want to suggest?
Hi Lou,
I posted about our best entry level bikes for 2020 recently. I think you can find something that will suit you. As for the size, you need something in the XS category. Somewhere around 49-50 cm.
I saw 17.5 inch road bike. What adjustments can i make other than buying a new frame to make it a 19-inch bike.
Hi LouB,
Normally I would not recommend a bike size that is bigger than what’s recommended for your body size. But, there are things you can do to make something like that work for you.
1. Lowering the saddle
2. Buying a layback seatpost
3. Getting a shorter stem
Do let me know about the outcome
Actually, the recommended size is 49-50 cm. The trek bike is 44.5 cm (17.5 inch). What adjustments can i make?
If that is the case the following can be lengthened and replaced:
1. Stem length should be longer
2. Layback seatpost(ask your LBS about it if unsure)
3. Saddle height
Hi Jeff,
Im getting a Vitus road bike from a friend, hes 6ft 4, im 6ft. Its my first proper bike, he used to race etc but the saddle looks super high, with that in mind would the frame likely be ok with for me with a lower saddle height?
I dont know what frame size he has right now. But some of the sizes over lap, i think the lower end of his actual frame size could work with the higher height range of my suggested frame size.
could it work?
Hi Richie,
That’s a good sportive bike for endurance ride. First what’s the frame size? He should be under the 61-62-63 cm XXL category. If that’s the case then you can lower the saddle. Also, check the saddle angle. Make sure it is level. Update me about the progress.
I’m 6ft female readg to buy a a mountain bike, what size ?
Hi Caroline,
You fall under the 18″ / 19″ XL category.
Hi Jeff
Really appreciate the guide, thank-you! I am not quite understanding the bicycle frame size to order for myself. Wanting to purchase my first cyclecross bicycle. My height is coming in at 184cm ( charts above state 58cm bicycle) whilst the inseam is coming in at 83cm ( charts above state 56cm bicycle).
Bicycle purchase options come in 56, 58 or 60cm frame sizes
Do you have a recommendation as to which way to go before ordering online?
Many thanks!,
Mark
Hi Mark,
58 should work fine with you.
Thank-you 🙂
Hi Jeff, I’m 5’8” with 29” inseam. Would I fit on a Small size for a BTWIN Riverside 100 or a Medium size? I’ve got an old bike that’s similar to the Medium size and I’ve been riding quiet comfortably on that. Also, when I put on shoes I have orthotics inside as I need it for my feet (which gives me another 0.8” in height). Thanks!
Hi Aaron,
Yes, you still fall under the medium size range. I suggest you still get the same size because you had a comfortable history with that.
Hi Jeff,
I’m 6′ 1″ tall with a 31.5″ inseam. I have a large frame 27.5″ Diamondback mountain bike and I’m looking to get a gravel/ road bike. This will be my first graveler, so I’m not sure about sizing. Any advice would be appreciated.
Thanks,
Josh
Hi Josh,
You need to get an XL(58-59-60 cm) frame for your gravel bike. Do read my post about the best gravel bikes to give you an idea. Cheers!
Hey Jeff I have a GT aggressor pro and I’m about 6-6’1 my bike is an XL is that ok for my size?
Hi Larry,
Yes, that frame size works for you.
Hi Jeff, loved the article and info you provided. In your expertise, what type of bike and measurements would you recommend for a 6’3” 220LB man that will be riding mostly on flat paved road and/or patches of rocky terrain?
Hi Carlos,
Thanks for the positive feedback. A 19″+ or XXL falls under your category. If you go for trail riding that’s not too hardcore, then get a hardtail.
66 year old male with 5’4″ body frame. What type of bike do I need to purchase for riding about in the city and paved bike trails?
Hi Larry,
If this is your first time getting a bike, then a should be a perfect bike for you. A 15” frame should be a comfortable choice.
Hi! I am looking for a bike for my 11 yo granddaughter for her birthday. She is about 5’2″-5’3″. Long legs. It’s all so confusing! What size would you recommend? She will just be riding around our neighborhood.
Hi Laurie,
Someone her size should be comfortable with a 15” frame size. You can choose between a hybrid bike or more specifically something like this.
Hi Jeff. Your article is a big help before I decide to buy my mountain bike. I am 5’5″ and inseam is 29.5″. I’m considering buying a 2021 Trek Marlin 7. S size is fine with me but tyre size is 27.5. I prefer a 29 tyre but its available starting from M size upwards. Looking at Trek size chart, it seems that the minimum inseam measurement for M is 29.9″. Do you think it will be difficult for me to ride the bike if I take the M size? Also, do you think a 29 tyre is too big for my height?
By the way, I will be using the bike for weekend biking mostly on flat roads and uphill climb. No serious mountain biking stuffs.
Thanks a lot!
Hi Melvin,
Not really. A 16” / 17″ frame under the Medium category works good on you. There other things that you need to consider to optimize comfort. These are saddle height, tilt and forward/aft position. I suggest you work on these when you get your bike and see which position feels comfortable.
Hello, I’m 5″3 and haven’t ridden a bike since young but am looking to try learning again. I am looking for a bike to ride in the suburbs. I was recommended to get a hybrid bike with a size small at a bike shop. so I was wondering what tire size I should be looking for?
Hi Sravya,
Have you seen this bike? A 24′ or 26″ should be ok.
Hi,
I am 5’8″. I measured with a 33 inch inseam. I will be purchasing a road bike. Both a 54 cm and 56 cm bike have been recommended to me. I don’t know which to purchase. I did test ride both. On the 54 inch bike the seat had to be raised to the max level. The 56 inch bike is usually recommended for people taller than I. How do I make a final decision? Thanks
Sorry for mixing up the cm and inches. should be 54 cm verses 56 cm as you know
Hi Shenee,
Yes they do overlap and can be confusing at times. You still fall under the medium category. You should be ok with 54-55 cm frame sizes. 56 is over your recommended size. If you can find a 55 cm then that’s good.
Hello. Perhaps I’ve misunderstood something but I’ve followed all of your steps and I got the following measurements.
First I measured from the crank to the seat clamp and my bike is 51cm/20″. I am 5’7″/170cm. According to your chart my bike should be 16″….so that means my bike is huge. It’s a hybrid/touring bike with 1.35″ road-ish tires for city use. I’ll put my thicker (1.75″) tires back on for more wild rides (summer touring).
Then I did the inseam, and my measurements were 76m which gives me the following”
City- 52cm
mtn- 50cm
road- 53
So the 51cm I measured (from crank to seat clamp) is just in the middle of the “inseam measurements.”
Now what?
Thanks!
Aviva
Hi Aviva,
Based on your height, the recommended frame size is a 16″. This falls under medium. For road 54-55 cm. For mountain 16” / 17″ M. Overall, find a bike under the medium category.
Hi, My height is 5.7. But i bought a cycle of 19 inches. Not sure what to do. Is it ok or shoukd i sell it off? Please advise
Hi Rakesh,
Is that a road bike or a mountain bike? XL is too big for your height which falls under Medium. Yes I think you need a bike that is suited for your size.
Hi , iam 6.2 feet in height and took 29 inch rim with 17 frame……is it ok to ride on .
Hi Shyam,
You are riding a frame smaller than your recommended size:19″ + XXL. I would not recommend it because it will cause discomfort in the long run. The wheel size is ok though.
Hey I’m a 62 yr old female my height is 5’10 I want to purchase a bike just to ride around the city r my hood can you recommend one for me please and thank you
Hi Wanda,
You need a 17″ frame size categorized under Large. Hybrid bikes will be the bike of your choice.
Hey! I’m looking for a bike for my sibling who is 5”9. My concern is she is overweight so I need to make sure the bike can support her. Thoughts?
Hi Em,
I suggest get her a Large 17″ hybrid bike. This will help her shed weight in the most comfortable way.
I bought my first road bike im 5’5 the owner of the bikeshop recommended me to get a medium size roadbike but i feel something is of is it just because im new to road bike or the road bike is small for me
Hi Arthur,
The road bike chart is different from MTB chart. You might be labelled as ‘medium’ on MTB but you already fall under the ‘small’ category on the road bike chart. Your ideal range(s) are: 51-52-53 cm. 53 is your sweet spot. I you get a proper bike fit for those incremental adjustments.
Hi I’m 6’2” and am looking at a bike with an 18” frame and 26” wheels. Does this sound ok?
Hi Walter,
Yes the frame size is ok. As for the wheels, it’s all about your riding style. 27.5 is the popular wheel choice these days, and they will look aesthetically pleasing for people of your height IMHO. Smaller wheels: manageable and light. Wider wheels: good for bumps and trails.
I’m 6’2” and was looking at a bike that has a 18” frame and 26” wheels.
Hi Walter,
Perhaps this link will help you? Let me know about your thoughts on these.
Hi Jeff,
Am 5.10′ height, can you suggest which bike size will fit me, am looking for road bike with gear. Suggest me a good brand to start wirh.
Hi Karunakar,
You need a large frame. Something around 56-57-58 cm. I suggest you take a look at these road bikes for a start. Cheers!
Hello, I am 5’3″ with 30″ inseam. I tried the hybrid style in size small, but I had to extend the bike post so high. Unfortunately, they didn’t have size medium in stock that I can try. Could you advise the bike size that might fit me better between size small and medium? Thank you.
Hi Olivia,
Looks to me that you have chosen the right size for your height. A 15” frame size should be ok for you. You can try with the saddle tilt to see if it can make a difference in the riding comfort. Try to tilt it back a bit and see if it solves the issue. Try to also check the saddle fore and aft. Move it a bit to see if it accommodates your issue. Let me know about it.

What’s my correct bike size inches/cm?
Hi Steve,
You should be ok with 21+ inches. You fall under the XXL category.
Hi, mu height is 5’9- 5’10 appx . I m looking for road cycle.Should I go for large size or medium size . Wheel size 26 or 27.5.
Hi Pankaj,
I assume you are talking about mountain bikes. Your frame size belongs to the large category. Choose 17″ / 18″. 27.5 is a good choice.
Hi,
Thanks for taking the time to respond to all comments.
I am 5′-11″ and have an inseam of 35″. I am looking at a road bike that is available in 54cm or 58cm. I believe I should go with the 58cm, but want to make sure this won’t be too big for me.
Thank you
Hi A,
Yes, and if you can find a 57cm frame, should be perfect.
I am a little confused, your table and formula calculations don’t match. For example using the mountain bike table for an inseam of 30″/76cm the recommended size is 16″/17″, but your formula suggests 30*0.66=19.8″ that is significantly off from the recommendation of the table. What am I missing here?
Hi ZahidN,
We are talking about inches as opposed to cm. No, you should not compare road bikes with MTBs because they are different. Remember, these are just size range that’s recommended and should not be taken with accuracy. We all have different body types. Little adjustments like stem length, seatpost height should accommodate the offset.
Hi
I’m 5.6″, nearly 100kgs. Need a suggestion of buying a bicycle for daily cycling 10kms. Awaiting your response. Thanks.
Hi Yogesh,
Are you riding mostly on the road? You can check our list of entry-level road bikes. Let me know if this is what you are looking for.
Hi, Jeff
Am 5 ft 9inch height, I ride MTB (mainly with in city) 27.5″ tyre size and 17.5″ frame. I feel a lot of pressure on my wrists while riding. What are the possible reasons and what is the solution to take care of it.
If it’s a problem with bike what possible remedy (other than buying a new correct size 😊)
Thanks..
Hi Rajaev,
Simple solution for that is to adjust your saddle tilt. Tilting the tip down will put all your weight on your wrists. Tilting the tip up will solve this issue. Make small changes though. Try it and let me know if it works.
Hi. Iam 157cms in height, approx 5.1.
I want to buy a bike for exercise purposes and is got roads and pavement for the same… Hence would prefer the road bikes, but all the road bikes seems to be big and I have no clue what to do… Any suggestions would be highly appreciated. I even thought to go for a mountain bike due to the height, and change the tire to road types… Could someone advise me which type and size of bike should I go for…
Hi Pradeep,
No bike is too large for anyone. You need to find the right frame size. According to our chars you need a frame size between 49-50 cm. This is under XS. Ask your bike dealer if they have this size. All road bikes have 700c tires. For beginners, a 28c or 32c is a good compromise.
XS size or 49-50cm frame size for a road bike
Hi Nevetz,
Yes, that’s what the chart suggests. May I know if this suits your height?
Hi l am 6.2, l am interested to buy a bicycle, which size suitable for me and also which is the best bicycle. Waiting for your references.
Hi Avinash,
A bicycle with a 19″ frame size is a perfect for you. As for the kind of bike you need, please provide me further information about your riding style. Do you like riding road or offroad? Do you like gears or single speed? For starter, you can browse our many categories:

I’m 5.4’ .. what’s my bike size ?
Hi Veronica,
You will be ok with 15 – 16 inches frame sizes. Your size overlaps between medium and small.
what’s my bike size?
Hi Molly,
In order to determine your bike size, I need to know your height.
Jeff,
From one of the post that you answered, I understand I need xs bike (4’11” & 150 lbs, 55 years old and have not ridden in years).
My question is, how does XS convert into actual bike size? 20”,22”, 24” etc.? Thanks for your help.
-Sam
Hi Kshama,
When we talk about sizing we refer to ideal frame size. For example on road bike that’s around 49-50 cm. On MTBs that’s a 14″ and below, while on city bikes/hybrid that’s also a 14″ and below.
Thanks for it but i need to know what inch frame e.g 16 inch frame . Also why is it so hard to find a bicycle thats like 16 inch frame ?
Hi Waleed,
Assuming you are looking for a Mountain Bike frame that’s size 16. A 16″ frame falls under Medium. This size is for someone who stands between 5’5 to 5’9. Do you fall under this range. As for your second question as to why it is hard to fine me medium size frame these days, the answer is simple. It’s due to the pandemic. I posted an article about that. Feel free to read and ask me any follow up question.
Hi Jeff,
I’m almost 6 ft tall and there are no hybrid bikes with large frames in my area. I’m testing a hybrid bike with an XL frame which I haven’t taken for a long ride yet. Should I be concerned if I’m right a the border line of the chart? Thank you for your help.
Hi Carlos,
Size categories can overlap. YOu said you’re almost 6 ft. Perhaps a frame size of 17″ should be ok. That’s under large. XL might be a little bigger for you.
Hi . I am 5 ‘6 . Looking for a road bike . Can you help me buy a road bike around 100-150 pounds
Also whats my frame size is it 16 inch if its . I cqn’t find bike that are 16 inch frame can you plz help me
Hi Waleed,
Your size fall under the medium category. Choose a road bike that’s around 54-55 cm. I posted an article about entry level road bikes. So far those are the only bikes you can have that will serve you well on your rides.
Hello Jef! Good day! I am planning to buy 2021 Trek Marlin 6. Can you help and recommend which frame size should I pick. I am 5’4″ in height with an inseam of 30-32″. Thanks!
Hi Ralph,
That’s a good brand. You better get yourself 15” / 16″ frame size. That’s under the Small category.
Hi Jeff,
I’m currently at 58cm bike which would be a large, would it be fine to get an 59cm bike frame as my bike is it’s the last in stock. Would this make a huge difference?
Hi Brandon,
Not really. After all, size category can overlam. A cm is not really a big deal.
Hi Jeff, so kind of you to answer all these questions so professionally.
I’m trying to buy my 9yr olds son’s next bike. He’s 4ft 8″ tall, inside leg 25″. Am I right in picking a 26″ wheel and I’m also a bit stuck on the right frame size?
Hi Natasha,
You are welcome and it’s always a pleasure to help. 26″ is too big for a kid’s bike. I wrote a cycling article about Hopefully this will answer your question. Feel free to post anytime 🙂

Hello, due to the bike shortage I had to order a size I didn’t have a chance to personally try. I am 5 ft 8 1/2. I still need to measure my inseam but I know my legs are longer than my torso.
I ordered the medium which is a 50 cm frame. Does this seem too small? Is it because the frame is lower?
Hi Patricia,
Actually, you are still within the recommended range. Try to make adjustments with the saddle height and angle and you should be good to go.
Hi there! My 15 year old, 6’4″ (tall and thin, 34″ inseam) son started mtb racing this fall, and we are having a hard time finding a bike that he can lean around corners, but also that gives him the best power per push for his leg length. Any thoughts? Thank you immensely!
Hi Amy,
A bike with 29″ wheels will indeed be hard to maneuver compared to a 27.5″. You also need to ensure that he has the right frame size of 19″ + which is under the XXL category.
Hi Jeff,
I’ve been looking everywhere for a bike that fits me with a 36″ inside leg at 6ft 7 tall. I’m looking for a road bike and have been looking everywhere. This will be my fist road bike and looking around for roughly £1000 give or take £200. Is there any bike brands you suggest looking at that I may not have seen yet? Its so hard to find one my size!
Hi Glen,
I agree it is challenging to find a bike for someone your height. Your range is within the 61-62-63 cm.These are under the XXL category. In terms of bikes under the range you are looking for, you might be in luck. Check out my article about Best Road Bikes Under $1,000. I am sure these are brands you already heard about 😉
Help! I’m confused 😕 I’m 5’7″ and inseam 30″, riding a hybrid Trek 20″ frame. According to the charts I should use a 16 or 17″ frame but according to method 2, 30×0.685= a 20.5 frame. What am I getting wrong? I keep wondering what I should do because I don’t feel the bike is too big when I pedal, the only moment I feel it’s a bit large is when I place my foot on the ground while riding and I’m trying to understand why at 3 inches above my size I do not feel discomfort riding. I have a positive ape index. Your insight would be very helpful. Thanks.
Hi Elisa,
We do have unique body measurements. What these charts do it to categorize you based on the general standard population, in terms of what are the recommended sizes that fits mostly people your height. But then again, these cannot address our body size differences. There are other factors that play here, including seat port height, stem length etc. Although 16-17″ are still your recommended sizes, it is better to have a proper bike fit. Feel free to send me a follow-up question. Cheers!
Hi Jeff can you please tell me what size bike should I get, I haven’t rode a bike in years. I found a bike cruiser 26 inch and I have fallen off several times, I’m 4’11 @156 pounds and I’m in my 50 I’m short Lol but I don’t want a child like bike, I bike ride with my husband through the city and on some trails, what size and kind would you recommend. . Thanks🚴
Hi Karen,
You don’t need a child bike. You only need to get a frame size around 14″ and that’s under XS. Good luck!
Hi Jeff. Please help me. I want to buy a bike. I didn’t have one since childhood so I want something simple and affordable now to get me started. I’m female 5”5 and 140lbs. What would you recommend? Thank you
Hi Sarah,
It depends on your preferred riding style. Do you want to ride in a more upright and relaxed position? If that’s so then you need a hybrid bike. If you are into road riding then a road bike is the best one for you. If going off road is what suits you best, then go for a mountain bike. Do let me know which one you like to do best. As for the frame size, choose something that’s around 5 – 16 inches.
Hi Jeff. Please help me. I want to buy a bike. I didn’t have one since childhood so I want something simple and affordable now to get me started. I’m female 5”5 and 140lbs. What would you recommend? Thank you so much
Hi Sarah,
Since this is your first bike, a more upright riding is the way to start. Here’s a bike that might interest you.You can start with a Medium size bike.
In my town there are so many uphills,slopes and turns. I am confused which cycle is suitable for these roads and iam 6 feet tall ,19 year old. Will 21 size cycle suits me?
Hi Nishanth,
Interesting question. I was thinking if I should recommend an MTB, a road bike or a hybrid bike. They are all great bikes for your type of riding. However, if you are not into off road, then I suggest you get a road bike . Road bikes are great for climbing because they weight less. I also suggest you get an XL frame size: somewhere between 58-59-cm.
Hi. Thanks for all the advice. I’m looking to get a gravel / multi bike. I am 5 foot 5 “ with inseam 29/30. So website indicate I should get a bike frame of 52 and then it’s S. But others says XS. There is a Specialized bike at a store with 52 and an online model with XS. Would both be ok? What would you recommend? I was looking at a Canyon bike – and the sales rep said I would be 2XS based on my height. So assume diff manufacturers have diff starting sizes? Now I’m more confused!!
Sam
Hi Sam,
The thing about labels like Medium, Large, XL etc is that they overlap. I suggest you go for actual measurement. The right bike for you falls under small, specifically a frame size between 51-52-53 cm. Ask for the actual measurement so you’ll get the right bike for you.
Hi Jeff, I just got a new bike. It’s 2021 Trek Emonda SL5. The recommended frame size is 50cm. I’m curious if it’s the right size for me. I’m 5’7” height and just under 29” of inseam height.
Hi Nazar,
You are 5’7, therefore your road bike should be under the Medium category. 54-55 cm are the recommended sizes for you. 50cm is small for you.
My height is around 5’7 1/2…I think my legs are shorter than usual lol 😂 What size road bike should I get? I was thinking 54 cm? Is that about right ? I’ve seen conflicting information, some going as low as 50 cm and some as 57cm.
What to do ?
Thanks
Drew
Hi Drew,
You should be good with 54-55 cm. 50 cm is way too small.
I have two bike and sometimes ride my partner bike to .
I have road bike xs which is to small and I have mountain bike that is small. My inside leg is 29 and half inches I have order a new bike size small with 25″ wheels will I be ok with small bike
Hi Franck,
Do you feel comfortable with the bike? Categories like XS and S do overlap. It is more accurate to base the measurements on your actual height like how tall your are in inches/cm then we can conclude if you are riding a bike that’ too small or too big for you.
My wife is 5’9″…what size roadbike should I get her?
Hi Ryan,
Give her a road bike that is from 55 to 57cm. That’s somewhere between medium to large.
This is really useful for helping people navigate the many bike options out there. So here’s my question – how does tire size factor into this? By the charts I would need a 16-17″ frame (I’m 5’8″) but does that call for a particular tire size too?
Thanks!
Hi Jean,
They do. For example smaller riders will feel more comfortable with 26″ tires compared to navigating using 29″ tires. Smaller: Nimble, fast acceleration and lightweight. Large: Slow acceleration, hard to control, but smoother on gnarly rides.
Hi Jeff!! I am 5’4” female with inseam of 29”. Would a medium size frame with 29” tires be way too big for me? And what size would you suggest? I’m looking for a mountain bike for paved and dirt trails. Also what are the long term risks when buying a bike that’s too big?
Hi Vera,
Although I would pay more attention to frame sizes that wheel sizes(your’s should be around 15” / 16″ frame sizes), Wheel size can have significant impact on riding. A 29″ might be considered big for your size but I have seen people your height riding them. You need to test the bike first in order to decide if these are the sizes you should go for. Bigger wheels can mean comfortable ride on rough trails. But they are heavier and they take a little longer to accelerate. A 27.5 is a better compromise. The risk of buying a bike that’s too big is getting lower back pain and other discomforts.
Hello Jeff. First time to own a Mountain Bike.
More of a tweener. 5’6-5’7. Shop has advised me i can do both S or M. But they only have stocks for S with the color I like. The M with the color I dont like. Can I really be S? What are the pros and cons? Thank you so much!
Hi JP,
Good question there! The thing about categories such as XS S M L XL etc is that they overlap. I suggest you base the measurement on inches. For example, your recommended frame sizes are : 16” / 17″. These fall under medium category on our chart.Would you mind asking if they have frame sizes such as the ones I posted? The pros and cons aren’t that great but they will impact the quality of your ride. That is why it is best to find the right frame size(s) that fits you best.
Hello Jeff, Thanks for the article. Great sizing tips!! When you say frame size is this the same measurement as in the graphic for method 1 from the crank to the seat post?
Hi Yusuf,
Yes they all follow the same standard method. The only variance is using the cm and inches. You will also notice that the standards vary(a bit) depending on the type of the bike. This has something to do with overall geometry.
Hi Jeff.
I’m 43 year of age 5’10.5” with an inseam of 34.5”.I want bicycle for comfortable ride poster because of back problem.
I have sorted out simple roadster bicycle(100 year old design) having tyre 28″*1.5″ in spite they are heavy wt . Now they have two frame size 22″ and 24″.
In 22″ it is possible to touch ground in sitting on saddle which is useful during sudden brake.
but in 24 inch give better riding quality .Can you suggest which one to choose. Thank you
Hi Vicky,
You need a frame size that’s 17″. This is under the large category. Smaller or bigger than this will give you back problems. I posted an article about chwinn Discover Women Hybrid Bike which is an example of a bike that is suited for your riding position. Let me know if you have a follow-up question. A 24 frame is way too bog!
Hi Jeff,
Thank for reply.
What should be height of saddle top from bottom bracket. I already have bike with 17″ frame
Hi Vicky,
The answer really depends on your level of comfort. There are people who prefer a saddle height with a bend or there are those who like full leg extension. I suggest you check out these helpful tips and see which one you should follow.
Hi Jeff. I am looking to purchase a Trek Marlin 5 MTB. I am on the cusp for height. I am 5’4, inseam 29, with a positive ape index. Do I go small which is 15.5 frame with 27.5 tyres, or medium with 17.5 frame and 29ers? Thanks in advance!
Hi Jennifer,
You fall under the Small category. You should be OK with frame sizes 15” / 16″. 27.5 is good enough for you.
Hi, I’m looking for a tricycle that would be a good fit, for a taller man (6’9inch). It has become really hard to find a bike that’s gonna work for me. I currently have a disability that limits me to ridding on a tricycle to help me with stability while riding.
Thanks for your help, Ed
Hi Ed,
I wrote about a Izip eTrike in my Types of Bikes. Let me know if this sounds like a good one for you.
Hi Jeff I’m new on bicycle parts and was planning to buy a MTB for urban riding but I’m not sure what frame size or wheel size to get that fits according to my height. I’m 5’6″ with leg inseam of 27.
And which is better steel or aluminum frames? . Thank you.
Hi Rey,
You need a frame in the Medium category, somewhere around 16” / 17″. Steel(chromoly) absorbs vibrations. Aluminum is light but stiff. Are you sure it’s MTB you want for urban riding? Check out my article aboutBest Entry Level Hybrid Bikes If you really love MTB for urban riding, then do read my post about Best Hardtail Mountain Bikes Cheers!
Hey Jeff,
I am 180cm tall, yet still ride a medium frame. Does that work/or what size frame should I purchase.
Cheers,
Myles
Hi Myles,
You should get a frame on the Large category (17″ / 18″). But be sure that you are doing it for comfort reasons. We do have different body structures so what works for another person might not work for you. The chart is meant to set the ‘acceptable’ standard based on body size but we understand there are rare exceptions.
Thank you very much for extremely useful information.
Hi Sujeewa,
Always happy to help. Cheers!
Hi!
I have a question. My height is 4’11, weighing 102 Ibs and im planning to buy a mountain bike but im not sure if the size of the wheel matters? Is 26” will be okay considering my height? And any recommendations in what bike to use? Thank you!
Hi Bea,
That’s is a good question. First of all, you need to address the frame size too. A 14″ is ideal for you. As for the wheel, 26″ is a good choice.
Hey Jeff.
I’m looking at getting a bike, leaning towards a hybrid. Does weight play a factor in choose bike size? I’m 5’7″, inseam of 30″ and I weigh 245lbs. What size frame should I get? Thanks
Hi Nicole,
Hybrid is all about comfort and practicality. You fall under the Medium category, so you need a size 16” bike frame.
Hi Jeff. I’m 5’9.5” with an inseam of 31”. I’m looking at a bike seller right now that recommends giving yourself an inch of space between inseam and standover height, however the bike then that would work for me would be their extra small frame, 43cm and recommended for riders 4’9” to 5’1” with a standover height of 30.5”. Something seems off about this—I don’t believe my legs are particularly short. Their 54cm frame has a standover height of 32.5”. What is your recommendation here? Thank you for your help!
Hi Sean,
That is strange considering that you should be ok with frame sizes 16 – 17 inches. There are factors that can affect these, like saddle height and stem length. I suggest you check the bike yourself first before you accept recommendation on paper.
Hi Jeff, You are doing a great job by giving professional advices.
My height is 168.5cm (inseem seems 82cm when I pulled book up against crotch as if i am sitting on seat) I have Btwin Triban 54cm road bike which was bought in Decathlon. I am a beginner and I ride 1hour daily and weekly one long group ride up to 60-100km. I have developed a 20 degree bend in left elbow after an accident which means I can’t straighten my elbow ( due toMyositis ossificans developed after radial head fracture) once I was about to fall while steering with left hand while showing right hand signal at road crossing. My average speed is 20km/hr. I wish to reach 25-30/hr
1) Do I need to get 52cm bike?
2) can I shoten stem from 90cm to 80cm? Does this effect bike handling?
Plz help!
Hi Dhananjey,
First of all the issue is never about the frame. If you’re comfortable with that size then keep that. I am sorry to hear about the elbow.
Shortening the stem can indeed impact bike handling and you need time to get used to the new ‘feel’ of riding. But safety is our primary concern. Shortening the stem or slipping the stem can also help. Be sure to ask assistance from a bike expert during the process because it really helps when all angles/issues are considered.
hey there,
i am planning to buy a geared bicycle but the website i am checking mentioning size as 27T, 29T etc .
what does it means and my height is 5ft 7inch so which size would be perfect for me.
Hi Pravar,
These refer to wheel sizes. For your height, you should choose 16 – 17 inches frame sizes. You can be OK with either of the tire sizes. They all depend on your riding style anyway.
I would like to buy a road bike for myself but Im confuse about choosing the right frame size for me my height is 5’10 and my inseam is 82cm.
Hi Charles,
Your options are: 56-57-58 cm under the Large category. When you do, I recommend a proper bike fit.
Hi Jeff,
I want to try out MTB, so I’m looking to buy a second hand bike. I’m 5’1″, 28″ inseam, right now I ride a XS Giant avail road bike which i love… I might be interested in a Gary Fishier Opie Small 15,5″ frame. Do you think it will fit me. I find it hard to find XS bike unfortunately.
Thank you
Hi Julie,
You can also try 15” / 16″ under Small. It looks like this frame is still OK for you.
Hi,
I am willing to purchase a bicycle with wheel size 27.5 and frame size 18.5 and my height is 174cm ,would it be comfortable for me ?
What do you think?should I buy this bicycle?
Hi Ombir,
18.5 is too big for you. You should get a frame size that’s 16” / 17″ under the Medium category.
Hi,
I am trying to buy a bike for my son for college— and I have to choose one without him available. He is 5’9 and about 190 and athletic. He will use the bike to get around campus and to bike to the archery range. Every bike I have seen goes by tire size. Any recommendations for him? I’d appreciate the help.
Hi Marcia,
It’s the frame size that’s more important than the tire size. Make sure you get him a 17 inches frame size. You also need to verify if he is more into road cycling or mountain bike .
What size bike frame do I need? I am 31 years old 6″ tall. I would not suggest getting the bike from Walmart. My Stepdad bought a mountain bike from Walmart. He didn’t even get it out of the parking lot and the pedals came off. The people who the bikes together for Walmart don’t know what they’re doing.
Hi Kristopher,
Your size falls under XL so you should get a bike that has a frame size of 18″ or 19″ XL. I think it is better to get from reputable stores. All the links that we provide here ensures quality. I would also suggest that before buying a bike, you should first get a bike fit to ensure you are taking home a bike that fits you well. Don’t second guess.
Hi Jeff,
Thanks for such an informative article.
I have an opportunity to buy a Specialized Sirrus (Hybrid) at a really good price.
Problem is, its a sixe XXS.
My wife is 5’3″ with a 29 inch inseam. Is that too small?
When I look at the major difference between XXS and S…(which I would buy without hesitation).
It’s Seat Tube, 360mm vs 440mm.
Some of the other measurements are 25-50mm (1-2inch) shorter.
Top tube is 531 vs 559mm
Head tube is 121 vs 147mm
Reach is 373 vs 393mm
Stack is 536 vs 562mm
Seat Post Length is 300 vs 350mm
What do you think. Should I buy this bike? Will it work?
Hi Al,
Thanks for the positive comment. XXS is too small for someone who is 5’3. A centimeter can really make a difference especially when it comes to road bikes. Her range should be 51-52-53 cm and they fall under the Small category. You should hesitate as it may cause her discomfort in the long run. I suggest a bike fit before getting any bike.
Hi Jeff, I currently have a 26” mountain bike and I’m about 6’0 tall. I’ve put the seat to its tallest height but my legs still can’t get a full extension. Would it be best to get a new/taller stem?
Hi Maya,
Fist of all how big is your frame size? For someone your heigh, you should have a frame size that’s around 18″ / 19″. That’s under XL. 26 is also too small. At least a 27.5 or a 29″ wheel size is best. Check out the frame size before buying anything because you might end up trading the whole bike for one of your size.
I have a Diamondback Edgweood bike which is great for 6ft and taller for sale. It’s way too big for me and still in almost new condition. Looking for an interested buyer.
Hello Jeff, wow what a helpful post! Keep doing the good work.
I am 36, 175 cms and have a lower back problem. I am looking for a used bicycle to commute to office (less than 8 mins ride) daily, and for some casual riding maybe 4 times a week (about 2-3 kms per day). Bikes with higher wheel sizes (27.5) appear more appealing to me, so thats what I am planning to go for. Is the Medium frame size (I dont know how many cms/inches!) ok for me? Also, is ride quality and speed better with these bigger tyres? Do consider the fact that I need to keep my torso upright to alleviate my lower backache.
Lastly, can you point me to a blog which explains the basics of gear shifting. Thanks a ton!
Hi Fahad,
What you need is an urban bike designed for daily commute. There are two types of bikes that might appeal to you. One is a hardtail MTB and the other one is a cruiser/city bike type. Both have the kind of riding position you describe. Make sure you choose a 17″ frame which is categorize under Large. Bigger tires create smoother rides especially when you live in an area with potholes and gravel. The 27.5 tire size is common these days. So that is a good choice.
Check out our post about Best Hardtail Mountain Bikes and also Best Commuter Bikes You Can Get
Thanks for the response Jeff. I managed to get a 17inch Mountain Bike (Upten River) with a 27.5 wheel size. Any recommendations of saddle height setting considering my backache? Also I am really not able to get the gears going, please guide me on it. Thanks a lot!
Fahad
Hi Fahad,
I am glad to hear that! I would suggest you get a proper bike fit to ensure long-term confort. You can also make minor adjustments on your own and ensure that the set up feels ‘right’. You can also use this link as a practical guid. Remember, back ache can be due to a saddle moved further back. Good luck!
Hi, I’m 6 feet and I’m thinking about a 26in wheel will work?
Hi Wence,
It all goes down to personal preferences. There is nothing wrong with getting a 26″ tire. People your height even ride in folding bikes with 16″ tires. It’s all about bike fit and adjustments. Try it first. IT it feels good then it is perfect.
Hi Jeff
I am 4 ft 10 inches tall, and I am looking for a new comfortable bike that would fit me right. I am not sure what size to get, do I go by my inseam measurement or bike frame or wheel size?My old bike is an Electra townie 7D and I think the print on the wheel says 24, is this the wheel size? But I find this bike to be too high for me, and hence not a very comfortable ride, and so I am looking to get a new bike that would fit better. Please help.
Thank you.
Hi Cory,
Yes the 24 refers to the wheel size which I think is a good fit for you. Look for a 14” frame size which I think will be a good fit for you. Check out our post about Best Commuter Bikes . Scroll below and I am sure you will find what you need. Look for something that says ‘low step’ on the description.
Hello, my wife is just about 5 feet tall maybe 5 1 .. I was gonna get her the Diamondback syncr 24… it has all the components I want for her (Sram nx Hydro brakes etc) but sold as a kids bike.. Killer bike under 1000 if that would work for her..
Hi Erik,
As long as the bike is under extra small category then it will fit her. Make sure to get her a bike with a 49-50 cm frame. Cheers!-Jeff
Hi I’m a little under 5’2” age 56 200lbs will a 26” beach cruiser from Walmart work for me
Hi SherAn,
That would be perfect. Be sure to choose a size 15″ frame size.
Hi…i am 41 and feel like i should start riding bikes again….your website is very helpful…..measured my inseam and its 82cm around 32 inches and my height is 183cm so as per ur chart a 17″ or 18″ bike frame size should suffice my needs. Here in Mumbai the specification is 26T….just wanted to clarify what that means and what should I go far ….preferably a city bike…
Hi Hermant,
The 26 refers to tire sizes. 26 used to be the standard for mountain bikes but now there are sizes like 27.5 and 29. If you choose the city bike types then an 18″ should be perfect for you. Please read my post about best bikes for commuting. Scroll all the way down, and you should be able to see the kind of bike you are looking for. Cheers!
what type of bike is comfortable for riding like 2 hrs . i have ridden on some rentals and 1 hr in they are sooo uncomfortable and butt hurts
Hi Jayne,
Try cruiser or city bike types types. They are made for commuting and long rides.
Dear sir,
I want a chart of bigger and smallest cycle .
I know three types of cycle
My son age 13.5 yr which cycle use increase height
I don’t know which cycle
.please guide
Thanks
Warm

Hi Vivek,
We do have a Kids Bike Sizes Chart. Tell me what you think. If you can also provide your child’s height, maybe I can also look for the best fit for him.
hi,
i am an adult,180 pounds,5’1” but never have ride a bike before,what bike you recommend?
Hi Ivonne,
A cruiser bike is the best entry bike for those who haven’t ridden bikes yet. These bikes are comfortable and great for commuting. Check out our post about best bikes for commuting and scroll all the way down to find the cruiser bikes that will fit you. If ever you have decided to get one, make sure you choose a frame size that’s 15” under the small category.
I’m 6 foot 300 lbs , what kind of bike should I get that fits good?
Hi Caesar,
Generally, you should be good with a bike that has a frame size of 17 – 19 inches. The kind of bike you should have depends on your preferred riding style.If you enjoy riding on paved surfaces and also off road, then a hardtail mountain bike with a 29″ wheels is something you will enjoy. If you prefer just easy cruising in the city then a hybrid or city bike is what you should get. Let me know what you prefer.
hi!
Could you help me with sizing for a city bike? I am around 5’5/5’6 with leg inseam of 29.5″.
thank you!
Hi Maddy,
Get a 16” frame. It is categorized under medium size. I would recommend a bike fit as well.
Does any one know where to buy a Comfort/Beach cruiser for someone that is 6’1″- 6’3″. I am not seeing any 21″ frame, they seem to have only a few or don’t sell XL frames. Anyone know some sites to find bikes like that for that size?
Hi Wes,
Were you able to visit the Cannondale Treadwell Website recently? You might be able to find the bike of your choice. Do let me know if this helps.
Do you know any with shocks or storage rack?
Hi Wes,
We have a post about that. Please have a look and then let me know if you have made up your mind. Best Touring Bikes.
Hi Jeff! I’m getting back into riding after a long time. I’m 6’6″ 220 with a 34″ inseam would love to hear your thoughts on frame size.
Thanks.
Hi John,
For a person your size, you need a frame size that’s 21+ inches. Congratulations for getting back into riding!
LOL, the first thing to be able to do is math! I just realized all my math was wrong. It helps to know the difference between cm and inches.
Hi George,
That is true. The simplest way if to just look at the first chart above. However, if you want a more specific recommendation especially for road bikes then better consult the chart for that.
I’ve got the problem of having a long torso. (6’2 with maybe a 33″ inseam). As a result, when I used the guides in the article I got as recommended sizes: 19-21″, 22″, 18″ and 17-18″. Basically, all they told me was that I’m tall. What may affect things is that I’m looking more at a city bike with a straight bar for exercise. If I’m getting the same workout, I don’t care how fast I’m going.
Hi George,
If you look at the city bike chart you’ll see that you need a 19″ frame. There is a specific chart for that because city bikes/ cruisers have different geometries compared to sports bikes.
Hi, I hope you don’t mind me troubling you with yet another personal enquiry!
I’m a 5’8″ female with inside leg 32.5″ and according to the standard charts I should ride a 54/55com frame. I already have two bikes this size; one ~20 year old steel frame and the other ~12 year old Specialized Allez but both are too long/big for me. Both are fitted with 6cm stems and I have the saddles as far forward as they will go (aiming for my knee over the pedal). Due to the slightly less vertical seat tube of the Allez I had to reverse the seatpost to achieve this. (Required a custom clamp to maintain the horizontal position)
I’m looking to upgrade and this time would like to get a bike that fits!
I had a very brief go on a 52cm frame; the saddle was about 0.75″ too low, I couldn’t check my knee position and would need a shorter stem than the 10/12cm standard.
Do you think a 52cm with reduced stem would be OK ….. or should I even look at a 50cm, perhaps with standard stem and longer seat post?
I’d very much appreciate your suggestions/thoughts on this. Thank you
Hi Lena,
Your ‘sweet spot’ is a 55cm frame. However we all have different physique so sometimes the recommended frame can be bigger or smaller for us. If the saddle is too low then you can try to raise it a bit. Try raising the saddle first before going with the reduced stem to see if it works. Try to work with the saddle angle as well. Let me know if raising the saddle has made a difference.
Hi Jeff,
Thank you for your reply – but I’m not sure I explained myself properly.
On both my current bikes the saddle is raised so that I have a ‘nice bend’ to my knee as indicated in your ‘How to fit a bike’ section.. This aspect of my set up is fine. My problem is that for the ‘correct’ frame size, the top tube is too long, necessitating the shortest stem I can get as well as moving the saddle as far forward as possible.
Rather than going bigger as you suggest, I feel I need a more compact frame, hence looking at a 52cm (maybe 50cm). The thought being that this will reduce the reach whilst a longer seat post would enable me to get the right height.
Maybe in these difficult days I need to make a ‘fitting appointment’ …
Hi Lena,
Yes I see how it makes you feel uncomfortable. I’ve observed this issue with fellow riders who seemed to have problems with reach especially on road bikes. Have you heard of afast forward seatpost? This will move you further forward making it easy for you to reach the handlebars and putting less strain on your lower back. A layback seat post can cause this issue. You certainly need to get a proper bike fit so that you can experiment with saddles, stems and also frame sizes that suits you. Who knows, maybe a 52 cm is indeed your sweet spot.
Hi Jeff, I am 6ft(183cm) and have inseam 79cm.
I want city hybrid bike but they sell in wheel size.
What wheel and bike size shall I get?
Also bonus question what is 700c or 650c?
Thank you
Ryan
Hi Ryan,
A bike with an 18″ frame is your ‘sweet spot’. The 700c is an ideal wheel size as it is the ‘standard’ wheel size for most road bikes. Remember, the bigger the wheel, the smoother the ride. But you also need to consider other factors such as tire sizes. Smaller tire sizes like the 25c is unforgiving on bad roads. A 32c is a good compromise.
I’m 5ft 2 inches, what size Adult trike would be best for me. 20 inch or 24 inch
Hi Barb,
First of all, your recommended frame size is 15″. 20″ or 24″ tires will do fine for you. Note that, the bigger the tires, the smoother the ride.
Hello sir first of all hope your staying safe in these days. Now my question is im looking into getting a beach cruiser and im 5’7 would a 26″ frame work for me?
Hi Jay,
Thank you for your positive wish. This is indeed the new normal, so we have to hang in there until this blows over 😉 Actually, you need a 16″ frame and that’s under the ‘medium’ category. As for the tires, you can choose a 24″ or a 26″ and it doesn’t really matter. However, the bigger the wheels, the smoother the ride. Hoping you get the bike of your choice.
Hi Jeff. I’m interested in buying a second hand bike that’s 51cm. I’m 5’8 so it is small for my height but it has adjustable handlebars and saddle. Will it be okay?
Hi Lauren,
Will you be able to try the bike out before buying it? I suggest you give it a test ride after making adjustments. It is smaller for your size. There are bikes that no matter how much adjustments you make, just don’t really feel comfortable.
Hi Jeff. Thanks for you advice!! I am 5’5.5″ in ht. My inseam is 30 ” and I have long arms. I am wanting an electric bike, like the looks of a mountain bike although would like a more upright position. Wondering too how tire size affects things? Also would like to have feet close to ground when stopped…..what thoughts have you??
Hi Lorraine,
A city bike type or beach cruiser is the kind of bike you are looking for. The upright sitting position or low bottom bracket enables you to have an easy way to mount or unmount from the bike. Tires do affect things. The bigger the tires, the slower they are to accelerate. But, they are good with bad road surfaces, as they can easily roll on them. Smaller tires can be too responsive that you have to be mindful with your stirring. Check out my post about Best Electric Bikes Today and I am sure you’ll find what you are looking for. Cheers!
Hi Jeff! You are godsend! I am about to buy a bike. I am 41 and around 220 pounds. I am 6 feet tall. Please recommend me one. The frame size etc. It will be mainly used for city commute. Thanks in advance.
Hi Murugan,
You have come to the right place! A wrong frame size will only give you pain and regret. For urban bikes, you need a frame size that’s 18″. This is under the XL category. For road bikes, your range fall under 58-59-60 cm, still under XL. For mountain bikes, choose 18″ / 19″under XL. Check out my post on the best road bikes of 2020 if this is something you think you want to get into.
Hi Jeff.
Thank you for your advice.
I am wanting to start riding a bicycle again, I am interested in the dutch style bicycles.
I am a female just under 5’8, my inseam measurement is 85cm. Most of the frame sizes I have seen are at 53cm or 57cm. I am leaning more to the larger frame of 57cm. However, have been told conflicting messages on which frame I should opt for. I would greatly appreciate your opinion on this.
Thank you again.
Hi Olivia,
Glad to hear that you are getting back to cycling! You are still within the medium range:54-55 cm when it comes to road bikes. For dutch bikes/beach cruisers/city bikes, you need to get a 16” frame. This is the type of city bike that you are probably thinking about.
Hi, Can u suggest a bike for an 5’3″ girl weighing around 55 kgs. The bike will be used on local plains and would be for starters. Just to get the feel of biking and exercise. Maybe 01 hour ride a day on tops.
What should be the size of frame and wheels and any specific recommendations that you would suggest. This will be in New delhi India.
Hi Prashant,
I assume you are looking for a road bike right? If so, you need to find a frame with any of these measurements 51-52-53 cm. The list of these bikes will give you an idea as to what suits you best and your style of riding, so please check it out.
Hi Jeff! Great article. Just wondering if a Medium size frame on a 27.5er wheels can accomodate my wife of 4’11” height with around 22″ seam? I’m planning to use her bike too. I’m 5’7″, so a Medium size is a fit for me. Thanks.
Hi Manuel,
She needs a frame size that’s extra small (XS). Your bike size will feel too big, uncomfortable and unstable for her.
Great article/website!
I’m 5ft6 and like the look of a mountain bike, but will only be riding it in the city on concrete.
Can i still get a mountain bike or should i opt for a hybrid or city bike? I just enjoy the sporty look of the bicycle.
Also should i get a bicycle size where my feet can touch the ground with my butt still seated on the saddle? Because i hate getting off every time i have to stop before a red light. But i’m not sure if you’re supposed to get off or not.
Thank you for this great knowledge!
Hi John,
There are many ‘standard’ ways of mounting and also unmounting from your saddle. You just have to choose what’s comfortable for you. There are people, especially urban riders who prefer that the tip of their feet do touch the ground when mounting and getting off the saddle. This feels safe. Urban bikes like city bikes and most hybrids(or even road bikes) have lower bottom brackets that will allow this flexibility. Mountain bikes are designed to have higher bottom brackets for trail and to avoid obstacles on gnarly situations. There are people who prefer to ride mountain bikes in the city because of what you said, it has a sporty look. You can choose tires that are good for paved riding(smaller with less tread) if that’s what you prefer. I suggest to do a lot of shopping around first and also watch YouTube videos so you can compare the pros and cons. Let me know if you have made up your mind.
Hi, Jeff. Thanks for all this information.
We’re looking to purchase a mountain bike for our 15-year-old who is 6′ tall with a 32.5″ inseam (athletic build), and my issue is that all the different size charts I’ve seen tell me different frame sizes (anywhere from 18″ – 21″). What would you recommend? Also, do we need to be concerned about tire size, too?
While I have your attention, do you recommend any brands that are good quality but not stupid expensive? My son isn’t an avid rider, but enjoys mountain biking with his Boy Scout Troop (and knows how to maintain & fix bikes). I appreciate your insight.
Hi Denise,
The sweet spot for his size is 18″. He can either get a 27.5″ or a 29″ tire size. If he is not really a hard core trail rider then you can get him a hardtail mountain bike. Check out the Cannondale Trail 5.
Thanks for sharing information with us. I have a question plz. What is the best way to know how long should I adjust my seat? Do you recommend this for me?? This theory?
https://youtu.be/sUNgZ_aRRL8
And how about the stem ?? Should I make seat and stem at the same level???
I have road bike
My height is 6.02”
Hi Marvin,
My rule of the thumb is that when it feels good then it is ok. There are many ‘standards’ that are shown in YouTube. There are even cases when bike fit does not really translate well in real-life situation. The stem and saddle level should always follow your comfort and not because they ‘look stylish.’ I suggest you play with the adjustments and make incremental changes (a centimeter at a time), and see if you feel you have achieved the sweet spot.
My height is 5’7” I want to purchase a mountain bike for on and off road.
Would the size tires make a difference for my bike size?
If so what size bike should I purchase?
Thank you for your time
Hi Sal,
First, it is best to get a medium size bike for your height. A 16” / 17″ frame would be fine. A 27.5 is an ideal tire size-not too small or too big.
so im 14 years old & i’m 5’3. what size wheel should i get for a mountain bike?
Hi Sam,
A 26″ would be a good wheel size to get.
Hello, Thanks for all your hard work on this. I recently ordered a Kona MTB bike from a local retailer–that seems to be the only brand available right now. I am 5’10” and an inseam of 31″ according to the Kona size chart I am at the top of the medium and bottom of the large. I opted for the medium, but have been agonizing over the decision. The Seat tube on the Medium is 16.5 and the Large is 18.5. The reach on the Med is 450 which matched my current bike (hence why I chose the medium). Do you have any thoughts on this. I plan to test before finalizing as they said I could always get the large, but I would have to wait a few weeks for the bike to come in.
Hi Adam,
The thing about bike sizing is that they always overlap. Your sweet spot is a 17″ frame. The 16.5 is the closest so I think that’s something you should consider.
Hi Jeff,
I just bought a Jamis Renegade thats 58cm. After reading your article I’m wondering if I bought the wrong size. I am 6’3 with a 36.5″ inseam. Is this bike to small for me? What size would you recommend? Thanks
Hi Chris,
Based on the chart, your sweet spot is somewhere between 60 to 61 cm. You are a few centimeters off.
Jeff,
Thanks for the help, I took that bike back and found one that fits me better.
Hi Chris,
Glad you found the right one! Enjoy your ride 🙂
Jeff, thanks for the feedback. Would you mind removing my last name from the posting. I didn’t mean to include it. Thanks!!
Hi Whit,
Not a problem 😉 Cheers!
Hi Jeff,
Very nice website. I’m 5-10″ and your recommendation for a commuter/comfort bike is a 17″ frame. In several other places I have seen 19″ as the recommendation for my height. Why the difference? Thanks!
Hi Whit,
It depends what kind of ‘comfort bike’ they are featuring. If you look at the road bike size, you can see that it has a different recommendation(when converted to inches) for people your height. Every type of bike has a different frame geometry that will also influence the size recommendation. Here, we only focus on the hybrid/city bikes that I have already reviewed in this site. That is why I recommend proper bike fit because you can really tell if the bike you are buying fits you well based on your level of comfort while riding it.
Hi Jeff, thank you for such a detailed and informative article. It’s just what I was looking for!
I’m sitting here with bruised knees because I just busted them riding my Dahon p8 folding bike with 16” wheels. Don’t get wrong. I think it’s a fantastic bike but I’ve had suspicions for years that it doesn’t work for my 5’-0” height. Maybe I was clued into that by the fact that I had to jump off the bike at every red light!
I’ve always struggled to find the correct saddle height. If the Saddle height is adjusted to allow my legs to extend when I peddle (which is how the bike shops always set it up for me), then whilst sitting on the saddle my shoes are more than 6” above ground and I have to jump off the saddle every time I stop! If I lowered the saddle (which is how I Just busted my knees) I can accommodate touching the ground but I would always have bent knees when riding.
Do you have a recommendation for how I can adjust the bike, or should I look into getting a new bike. If so, what do you recommend for a city bike for a vertically challenged 5’ footer like me?
Hi Joy,
Unfortunately, all folding bikes follow the ‘one size fits all’ principle when it comes to geometry. The problem is that all of us have unique body structures. Some have longer torso and shorter legs. Sometimes, it’s the other way around. It looks like you have a bike that’s too big for your body.Try to adjust the saddle fore and aft and also the saddle tilt. These factors can contribute to how you are positioned on the bike. If these things don’t work, then you better get a right bike for your size. There are city bikes that should give you comfort while riding. If ever you try to decide to get one, then get a city bike with 14” frame size. This is categorized under extra small.
Good information
Thank you! Be sure to check other links and tips!
Thanks for sharing information with us.
My height 5’6.5″ and inseam 30″. Suggest my frame size, wheel size and specify with detail category of bicycle for unpaved suburban commute of daily 40km in case my weight 68 kg.
Hi Bhanu,
If you are getting a mountain bike, then your measurements fall under: 16” / 17″ Medium
If you are choosing a road bike, then your size chart falls under: 54-55 cm Medium
If you are using a bike mostly for commute then a hybrid/city bike is good for you. You can get a 16” Medium.
So I’m 4’10” – the Cannondale Women’s Adventure bike says the Small (there’s no XS in this bike) is good for someone with a minimum height of 4’11”. I have the chance to get a used one – would I have an issue putting my feet down? I’m a new rider with a 27” inseam and 29” saddle height (I think)
Hi Marisa,
You can make adjustments with the saddle height, like lowering it down a bit to accommodate your height. I think that size still covers your height and you are good with frame sizes 47-48 cm.
If my height 163 cm what frame size you can suggest??
Hi Hanif,
For a road bike, you are good with frame sizes:51-52-53 cm which are all under the small category.
For a mountain bike, you are good with frame sizes: 15” / 16″, still under small. I hope this helps.
Thanks for sharing your knowledge with us. I want to get my wife her first bike, we are both new to biking, I already have a road bike. My wife has said she wants something more steady (she considers my road bike to be too light). Please can you give us an opinion on the bike in the link below? She is 5’4 and we will mainly be using the bike around our community.
https://www.canadiantire.ca/en/pdp/supercycle-surge-dual-suspension-mountain-bike-24-in-0711925p.html#srp
Hi Jay,
I think that is a good bike for her to start. The suspensions make it comfortable on bumps and also off road cycling. You can get her a frame size that’s ‘small’
around 15” / 16″. Send my regards to her and her journey into the world of cycling.
Very informative page. Thank you for the informations.
I have to commute total 36 km in Indian Semi urban road. My height 5’6.5″ and inseam 75cm weight 65kg. Suggest frame size , wheel size with other specifications and also type of bicycle to commute.
Give same information for my brother with height 5’10” and inseam 58cm weight 72 kg.
Hi AC,
Commuting by bicycle is the new normal! A medium size frame is good for your height. I suggest a 16” frame. You can get a 700c wheels. 650c also works. Check out this link about the best commuter bikes we recommend before making a decision. You brother needs a 17″ frame size.
Hi, thank you for this great page!
I’m looking for a comfortable/city bike but that can also ride on easy dirt trails. I’m 5’11” and want to make sure my feet can easily touch the ground when I stop. I thought a Large frame size would do the trick but I saw a 700C and got confused. Would you know if I’ll be able to put my feet on the ground when still? Many thanks!
HI Lua,
Yes, your can always make an adjustment on your bike to make your feet touch the ground easily. This is achieved by lowering the saddle. A 17″ frame is your recommended size. Now, a 700c wheel size applies to most road bike wheel size. Don’t let it bother you. And yes, you can still achieve that by making an adjustment that I have mentioned above. Check out my post about commuter bikes to give you an idea what’s best for you.
Hi there. I was wondering what size/type you would recommend for me in a ladies’ beach cruiser bike. I want something both easy & comfortable to ride. I am 5’4″ and weigh 190 lbs. , perhaps with a basket & cup holder, as I will solely be keeping it at our beach house and riding for exercise & quick grocery runs.
Hi Melissa,
A size 15” is ideal for you. It looks like our recommended urban lady beach cruiser is something that will suit you. You can also check out a list of commuter bikes to have more choices!
Hey Jeff, I am a 5’5″ woman looking to buy a Felt FR30W Women’s 105 Road Bike. Only the 43cm is left at my bike shop. Would it suit my height? Wanted your opinion before I buy. Thank you!
Hi Shami,
43cm is way too small. Below is your chart:
5`3″-5`6″ 51-52-53 cm “Small”
Anything above or below these will cause discomfort. Learn more about the best and comfortable road bikes in our road bike articles.
What would you suggest for an inexpensive bike for an 11 year old? He’s 5’3-1/2”. He suddenly wants to ride more, but he is an infrequent rider at best and he grows super quickly so I don’t want to make a huge investment that he will outgrow before he gets enough use out of it. Thank you so much.
Hi Michelle,
I understand your concern. I think your boy needs a bike that looks like thisone.
I’m wanting to get my daughter an adult tricycle with basket on the back for college. She’s 5’1″. Would a 20″ be ok?
Hi Jennifer,
A 20″ would be fine for her height. This video might be of good help to you. Cheers!
Hi Jeff,
Very informative page. Thanks for sharing all the info.
Need your advice in my search for a MTB. I’m 5’7”, 26” leg inseam (27” really but 26” to ensure comfort). I’m right in the middle of the Small and Medium size frames. What do you think will work best? Lastly, if I went for a Medium, will a 29” tire size work for me? This is what they have in stock right now.
Best,
HT
Hi HT,
That’s a challenging scenario regarding the only tire size they have available right now. There are pros and cons when getting a 29″:
Pros: smoother ride over bumps and rock gardens. Acceleration is also good during descends. Extra stability and traction. More resistance to pinch flats. Less tire wear.
Cons: They have heavier and weaker wheels. You accelerate slower compared to 26″. Braking requires more effort. Tight turns can be tricky. Feels awkward for shorter riders. I’d say go with the 27.5″ because it’s good for your size.
16” / 17″ frames are ideal for you. Enjoy!
I just got my 11 year old a 26 inch bike, he is 4’ 11” did i mess up?
Hi Hugo,
You mean a 26″ wheel size? It’s not really a huge issue as long as you have a frame size that’s 14″ or anything under small or extra small. Let me know if this helps. Oh, and have you tried bike fit?
Hello, I’m 5’10” and looking for a road bike. Would a 17” frame with 27” tires be a good size?
Hi Hailey,
Those are MTB measurements. Road bikes use 700c wheels. By the way those are the recommended MTB measurements for you(if ever you are looking for mountain bikes).
For road bikes:
Height: 5`9″-6`0″ Recommended frame sizes: 56-57-58 cm Category: Large
Hi, if my bike has a 17″ frame and has 26″ wheels then what is the total length of the bike please
Hi Andy,
Correct me if I am mistaken, but I think you are confusing bike sizing with gear inches. A 17″ frame falls under ‘medium size’ on mountain bikes and “large” under city bikes. a 26″ wheel size is just your regular ‘classic’ MTB wheel size.
Hi Jeff,
Your website is very helpful. I need your help. I am 20, 5’3″ and weigh about 48kg. I have never ride a bike but I want to learn. Is it too late? If not, what type of bike and frame size do you recommend for me. I am from an African country and some of our roads are quite rugged.
Hi Esther,
I’d suggest you get a bike with a frame under the ‘small’ category, specifically, a size 15″. For first timers, the best bikes are those with relaxed geometry, like our Best Entry Level Hybrid Bikes. Do let me know if you need more info.
Hey there. I’m a woman and want a somewhat upright ride, something approaching city bike geometry. I’d kind of rather have a hybrid that is faster and lighter but don’t want to stretch out too far for comfort for my 59 year old neck, shoulders and back. I’m only 5’9 but my inseam is 34”. I’m afraid that a larger bike will get longer along the top tube and stretch me out more. Any advice? Many thanks.
Hi Jacki,
Yes, anything with the city bike geometry provides comfort for casual riding around the city. Our lectra Townie Cruiser is a perfect bike for you.Another option is our Schwinn women’s bike.
Hello, so the article stated that you don’t need to test a bike out, find this wrong, different bikes have you sit different, lime the mountain bike, your back is hunch over, others you are seating straight up, others like the townie bike is just perfect, just saying, so if you don’t try them out how are you to know this, thanks
Hi Patricia,
The bike charts are there to give us the right bike size. But they are not the only way to solve issues like comfort and handling. Bike fit is essential because it eliminates future discomfort. While it is true that making small adjustments (on the saddle and stem length etc) can improve bike handling/comfort, bike fit is still very important. There are also people who are not very flexible, and are more comfortable with upright riding, compared to the aggressive position of road cycling. So, it is best to have an actual bike fit from your trusted LBS. Cheers!
Hello, I’m looking at a Trek Superfly 100 mountain bike that’s on an amazing deal, although the one available is a Large (19”) frame and I am 5’8” with around a 30 inseam I believe. Would this be too large? Would it be ideal to get a medium, 17” frame for me?
Hi Michael,
Fantastic brand as far as I am aware!Yes, that would be a little too big for you. 17″ is ideal. The bike size chart provides sizes that are considered as the ‘sweet spot’ for a rider’s height. Getting a frame beyond your recommended size will cause discomforts such as lower back pain.
Jeff,
Thanks for the article and all of the helpful comments. I am considering buying either a road bike or a gravel bike in the near future (online), but I feel like the charts I see are often conflicting when it comes to height versus inseam and frame size. I think I’ve narrowed my size down to a 54 for a road bike, however I’m worried because I once owned a size 51 gravel bike in the past and felt like it was too tall even with the seatpost all the way down, but maybe I just needed to get used to it as you mention. My height is 5’9″ and my inseam is 29.5″. I comfortably ride a size 19 MTB. I think maybe my inseam is shorter than most; let me know what you think.
Hi Jesse,
So glad you like the information posted here. Yes no two people have the same body measurements. These sizes are just ranges that are ideal for a particular rider size but then again we still need actual bike fit to be sure. You should be ok with a 56cm road bike. That’s under the large category. Riding a road bike after getting used to MTB is a new experience. The rider position is different because the geometry is more aggressive. It takes a while but you will get used to it.
I REALLY appreciate you for taking the time to make this article. My son is 5′ 11.5″. I haven’t road a bike in over 23 years. I definitely need a large seat for comfort I’m 4’9.5″ what size should I get us and brands? Thank you in advance for your time and response.
Hi Christine,
Welcome to the world of cycling! You should get your son a 17 inches frame. You need a 13″ or 14” frame to accomodate your size. For beginners, check out this link. Let me know if this helps or you need another option.
I am struggling to figure out a bike solution for my son. He’s a big boy and it seems impossible to find a bike that fits him and accommodates his weight.
He is only 6 years old, so he still needs training wheels. however, he is already 4’5” (53” tall) and weighs 110 pounds, and his inseam from ground to crotch is 21” I believe he has inherited my long torso and short legs.
I keep seeing various charts that say he should have anywhere from a 16-20” bike and i’m so confused.
I would be forever grateful if you could help me find something for him. every time I think i find a good fit, the weight limit of the bike is well below his weight. Or if it accommodates his weight, it doesn’t fit his inseam.
Hi Stacey,
According to the Kids Bike Sizes – Choose The Right One, he should be ok with an 18″ and 20″. You can go to a store and give them the measurement and they should be able to figure out what is the right size for him. Most of the time, the measurements overlap. As long as it falls within his range, then he should be ok. Below are his size charts:
6-8(age) 3’8″ – 4’0″(Height) 115-120cm 20″-24″ 50-60cm 18″
7-9 4’0″ – 4’5″ 120-135cm 22″-25″ 55-63cm 20″
Hi Jeff, Just found this site with lots of good information, so thank you. I am considering purchasing an adult tricycle for myself, but only see the sizes listed for 24 or 26 inches. How does one determine which is the best size?
Thanks so much.
Marilyn
Hi Marilyn,
Riding a tricycle is all about comfort. There is no such thing as ‘one size fits all’ but rather, your body size should fall within the range of sizes that a tricycle can accommodate. This might help you.
Hi Jeff
This is a great article, but i’m Still a little worried. I have a small 15”hybrid, and i’m Looking to get a electric road bike for commuting. Looking at the bike first is not an option. The smallest frame size they do is a small. Will this be ok, although I am smaller than the recommended 1.60 m? As long as I can stand without the crossbar digging into my crotch I will be happy
Thanks
Halina
Hi Halina,
15″ is under the small category so you should be OK.
My height is 5 feet 2 inch… What is the perfect cycle frame size and wheel size.
Hi Kieran,
First of all you did not indicate what type of bike you want. Generally, you should be ok with a frame size that’s between 14″ to 15″. For the wheel size, you can choose between a 24″ and a 26″.
Hi fiends,
I’m 5’10 what size bike I need to buy?
-Best
Hi Misha,
Get a frame that’s between 16 – 17 inches.
Hi i’m 5’1 will a 20 inch bike be okay? Tnx
Hi Marija,
No. get a frame size between 14-15 inches.
Hi Jeff,
I am 5 feet tall and my brother is 5.11 inches is there a common size which we both can use comfortably, if so what frame and tyre size would you recommend?
We both are new to cycling and we are looking for a MTB to ride on flat city roads.
Please suggest.
Thank you!!
Hi Anu,
Your size: 15” / 16″ S
Your brother: 17″ / 18″ L
There is no MTB that has a “one size fits all”.
Hi Jeff,
I am trying to look for MTB or road bike for a commute on mostly flat, but sometimes very steep terrain (all paved). I am 6 ft and about 260 lbs. With the research I have done so far, most places are saying tire size only. What range for both frame and tire size should I look for?
Hi Jon,
For frame size: 18″ / 19″ XL
For tire size, get a 27.5
I have a rad Easton 67 can you tell me what size it is?
Thx
Hi Ron,
You can measure the length of the seat tube and then you can compare that to the chart. Watch this video to give an idea on measuring.
I am only 4’10” with a 27″ inseam. I’m so confused. I ride basic city trails with a few small hills. What kind of bike and fit would work for me?
Hi Cathie,
Gravel bikes are hot these days because you can ride them both in the city and on trails. They are lighter than mountain bikes and are fun. Check out this link. Do let me know if you want other option.
Hi! I’m trying to buy a bike for my daughter. Thankfully, she’s the same size as me, 5’4 approximately 116 lbs. I want a cruiser. I’ve never ordered one before and all these measurements are confusing. Will a 15 or 16 inch be ok?
Hi Jennifer,
Both sizes will be ok 🙂
Hello I always ride on a 54cm frame and people used to tell me it was a little small for me. I started using a 56 cm and feels a big. I’m 5 11 and my inseam is 32. Small legs, large torso. Would it be better to ride 54cm with a long stem?
What do you recommend?
Hi Tony,
There are reasons why this is so:
1. Although the frame was initially too big for you, your body has already gotten used to it
2. Our body structures vary from person to person. Some have longer legs and shorter torso or the other way around and so that explains why bike charts don’t apply to us. Bike fit the the best way to know that.
If that size feels right for you then go for it.
Hi!
Thank you for your post! I am looking for a ride bike. My height is 165 cm and inseam is 70cm. The bike I am looking for has 49 and 52 sizes. It looks like I am between sizes, which one is better to choose bigger or smaller? Thank you!!
Hi Katy,
They still fall within your range. You can get the 52, it doesn’t matter.
Hi, Im 178 cms, 84 kgs and want to buy elife air (https://www.elifebikes.com/en/elife-air/) is this suitable for my height ?
Hi Sharath,
Folding bikes are made with a ‘one size fits all’ idea. That should be OK for you.
I’m 6’2 what bike would fit my size
Hi Curtis,
Most preferably a 19″
Hi Jeff
Really impressed with your work.
I am new to cycling. I am 6ft . 110 kgs
Want to start with a hybrid bike .
I would really appreciate your advise on the size of the bike I need to buy
Hi Moin,
As long as you don’t go above or below 17″ and 18″ then you are OK.
Hey hope all is well. I’m 5’11. I just bought a 58cm bike but I’m wondering would this be too big of a fit for me? I’m also 135 pounds. With a pant size of 30’
Hi Kadeem,
No, it is still within your range. So 58 cm is still ok.
Hello. I’m 5’6.5″ tall (inseam is 30-inches) and usually ride small to medium-sized MTB’s. Saying that, I’m interested in a 29’er and was wondering what size frame you would suggest for said 29er?
Hi John,
You will be ok with a medium-size frame, preferably between 16” / 17″.
Hello, im 5.11feet tall and, i weight around 105kgs , i need to buy a city bike, what frame size and wheel size would u suggest me for a comfortable ride sir
Hi Ruthvik,
You fall under the large frame category. A 17″ frame is good for you. Try getting 700c with 32 or 38c tires. These are comfortable tires to ride around.
Hi Jeff,
You have done excellent article. It really very useful for me. I have planned to buy new bike or daily use of 15 kilometers in city roads . My height 180 cm, weight : 81 Kg, Inseam 79 cm , As per your article, i have opted 17″ Frame (Large) size. but I do not know that how to set/select saddle height, wheel size and handle bar angle .
I am expecting your reply. Thanks in advance Jeff
Hi Kumar,
Good question. Getting a bike fit is important to ensure ride comfort. For saddle height, watch this. For wheel size, the most common and comfortable to ride is 27.5. For handle bar angle, watch this.
Hi Jeff,
I ordered the 2021 TCR ADVANCED PRO 1 DISC. My height is 5’5, one store recommended an XS and another store recommended Small. I ended ordering the Small. When I went to GIANT’s sizing guide my height is between XS and small. Please help me make the right choice. Here’s the link of their sizing chart . https://www.giant-bicycles.com/us/tcr-advanced-pro-1-disc-2021. Thank you in Advance for your expert advise.
Hi Ian,
I feel your worries. Size categories can overlap and that is why it is better to see numbers or ranges that will fit us. Look at the road bike chart below:
5`3″-5`6″ 160-168 cm 51-52-53 cm Small
As you can see, 5’5″ is categorized under small. As long as you get the frame sizes that are closer to your height then you should be ok.
Hi Jeff, first mountain bike, 5`11′, inseam 76cm. negative ape index, should I get a 16.5′ (42cm) or 18′ (46cm)?
Hi Henry,
I’d say get the 18″
Hello Jeff! (1) My son needs a bike with training wheels – he is 9.5 years old, and 4′ tall, about 55 lbs. He has been hesitant to learn, but I think now is a good time as any. What size bike can I get for him that still has training wheels? (2) I also need a bike for myself – I am 5′ and 125 lbs. I don’t mind getting a girl’s bike for myself so that it fits better. What size bike can I get for myself? Thank you so much!
Hi Joy,
It’s great to know you are getting your son early on cycling. Get him a bike with size 14″ wheel. For you, get a bike that’s under xs(extra small) with a frame size of 14″.
I’m 5’7”-5’8” with a 26-27” inseam, would I be better off with a 16 or a 17 inch frame?
Hi Joe,
You should be OK with a 17″ frame.
I have a 26-27 inch inseam and I’m 5’7”- 5’8”. Would a 17” bike work be best or 16”?
Hi Joe,
A 17″ is best.
Hello sir
What is the minimum height of a bicycle of 16 inch frame size and 26*1.95 Tyre size and will it be suitable for 170 cm height person
Thanks
Hi Asif,
That bike should be ok for you. That falls under medium.
Hi, I’m 6’3, what size hybrid bike should I purchase?
Frame & inches?
Hi RC,
Get something that’s labeled XXl with a frame size of 19″.
Hello Jeff, excellent article, very useful! But it has put me in a dillemma and I would value your opinion. I’m 175 cm tall (5’9), with an inseam of 78 cm (30 3/4”). I have an old bike (advertised as a city bike but today we’d call that a hybrid – triagular frame, relatively narrow tires, straight handlebar). The frame size is 57 cm (22.4”) – measured like in the picture under “Method one” in your article. Judging by all info in the article, I’d have to conclude this bike is too big for me. Since I haven’t ever used a different bike, can you please tell me, what I could expect if I bought a smaller framed bike? How does the frame size itself influence the ride? Thank you!
Hi Miha,
Not really if you look at the Road Bike Chart: 5`9″-6`0″/175-183 cm = 56-57-58 cm(frame) “Large”. As you can see, you are still within the range.Just be careful with the conversion. I think you are OK with that size. I think your body should also be the judge when it comes to bike sizes. That is why bike fit is important because no two people have the same fit. The range is just there to show you that you are ‘safe’ as long as you don’t go below or above the range. Various factors like saddle height, stem length or handlebar angle can also contribute to the comfort of riding.
Hi Jeff. 1st road bike. 64 years old. 230 lbs. 5-11.5 , 30.5 inseam. Do I purchase a 56 or 58 bike.
Thanking you in advance.

Hi Rick,
it doesn’t matter. They still fall within the range. Enjoy the ride!
My son is 9yo but is already 154cm. He’s a tall skinny kid, at only about 95lbs. Has already outgrown his bmx style bike, and I think we need to jump him up to more of a mountain bike style. With him growing so quickly, what do you suggest? We looked at a medium, but it seems so big for 9yo, but then looked at a small and thought he would outgrown that in a year.
Hi Rick,
I agree that he is in a situation where he needs a bike that fits his age group. I’d suggest that you need to get him the right size to avoid discomfort. You can always sell it once he outgrow the size. We are looking about 2 years, which isn’t really hard. Here’s the range for his size to give you an idea: 148-158 cm (which he falls under) 61-73 cm/ < 14″ (the range of sizes to fit him) XS.
What’s the best size bike for a 6’7” man, with long leg length
Hi Kim,

Hi,
I am close to 6.1feet, male 92k.g, and looking for bikes to ride. This is for riding in-roads with in the community. Can you suggest what type, frame size and wheel size should I buy?
Thank you very much.
Hi Rajeev,
Get frame sizes between 17 – 19 inches. How about checking my post about hybrid bikes? This category might be something that will appeal to you. Do let me know what you think. Cheers!
Hey, just bought a new M size trail mountain bike, but im seriously curious bout the sizing the bike shop recomend me L size but need to pre-order , couldnt wait much longer i just took the M size , im about 6 ” or around 183, so whats your opinion..?
Hi Shawn,
Some categories overlap so it is safer to pay attention to frame sizes. As long as your bike falls under the 56-57-58 cm measurements then you will ok.
Hi, my height is 187 and I saw a product which says 26’ size mountain bike is right on my size
Hi Ahmed,
Here’s your chart: 6`0″-6`3″ 185-193 cm 28`-33` 71-83 cm 18″ / 19″ XL
26″ can mean wheel size. Most mountain bike wheel sizes are: 26″ 27.5″ and 29″.
Please kindly advise me. I am 5feet 5inches tall. I am contemplating on buying a bicycle of model: 28 “inch city bike Shimano 21-speed. Please is it a good fit for me?
Hi Raphael,
16” frame is good for you.
Hi Jeff I’m trying to determine my road bike size. I’m 5’9 and ride a large size mountain bike (Giant Trance) although for my height I should fit a medium. I could not ride the medium it was too small. My inseam is 34” and I have a short torso we caused the problem of size. Can you help me to determine which size frame to try as I want to buy used.
Hi Sarah,
You can get a large one. 56-57-58 cm range of frame sizes are ok for your height.
Hi, I am 5’ 5” and my inseam is 30“. Am looking for a bike and I don’t see many options online. Among the limited options currently available, is 26” wheel and 17” frame a good size for me? Thank you!
Hi Sam,
Are you getting a road bike or a mountain bike? 17″ is too big for you. Get something around 15″ – 16″.
i want to buy a mountain bike which my self and son ride (same one). i am 5.6ft and my son 5.3ft (12yrs old). What frame size and wheels size suitable for us? can you please suggest?
Hi Suresh,
You two fall under different categories in frame sizes. You need a frame size between 15″ – 16″, while he needs 13″ – 15″. But, if he is 12, then he can ride the same bike as you have soon. For wheels you can get a 26″.
Hi
I’m 5’7″ with a large body frame (fat). I’m looking to move to Gravel Bikes from Hybrids. And not sure if I should go small or medium size frame. Please can you advise?
Hi Richard,
You can get a medium size frame that between 54-55 cm. Gravel bikes are fun!

Hi,
I am close to 5’3, female 140 lbs, and looking for bikes to ride. This is my first bike and unfortunately since not much bikes are available in stores, or online, am not able to check them before buying. This is for riding in-roads with in the community. Can you suggest what type, frame size and wheel size should I buy?
Thank you very much.
Vid
Hi Vidkar,
Since this is your first bike, I’d suggest you get a bike for comfort. You frame size is in the small side, so you should get a size 15″ frame. You can get a wheel size somewhere between 24″ to 26.” Here are the best bikes you can check. Let me know if this works for you.
Thank you very much, will check it and get back.
Hi Vidkar,
Thanks for dropping by. Cheers!
Hi, the product I just found only shows the bike size: “150x25x(59-70)cm/59×9.8x(23-27.5)in” on ebay. My height is about 169cm and I don’t know if the bike would fit me.
Hi Peter,
You fall in the medium side. You need a frame that’s between 16 – 17 inches. Beyond that will cause major discomfort.
Hello, I am 153cm in height. Looking to buy a city bike. While I understand that 14-15″ might be the size for me to go for, how do I really read the wheel size that’s given (20″, 24″, 26″ etc? Thanks for your help in advance!
Hi Garima,
Wheel sizes can contribute to the comfort of the ride. The bigger/wider, the more comfortable. The advantage of tires with smaller diameters (20″ or 16″) is that they are easy to store and they don’t weight a lot. It is up to you which do you favor most: portability or comfort.
Hey Jeff I’m trying to find out what frame size works best for me. I’m 5’10 (or very close to it). I used the inside seam measurement method x.66 for mountain bikes. The measurement I came up with was 52.xx. Curious what size you’d recommend
Hi Chance,
You need a frame sizes around 17″ / 18″. Any of these will work for you. They are under the large category.
I need a cheap bike that’s 16 inches
Hi Elizabeth,
How about reading my post about Best Entry Level Hybrid Bikes? You might find something of interest 🙂
I am 5′ 5″. I am thinking to buy James trail x expert. The store has only 15″ frame (small). From the chart, I can either use small or medium frame. Jamis has only frame size of small (15″) and medium (17″) and does not have 16″ frame. Is it ok to use small frame or medium frame in my case?
Hi Jehen,
You should be ok with 15″.
Hi Jeff,
My height is 176cm (5 feet and 9.3 inches) and I have an inseam of 86,5cm (2feet and 10inches).
Judging from the inseam, your tables tell me I need size 20 ” 21 ”. This is of course too big if you also take into account my height.
Can you please help on this?
kind reagards
Hi Koen,
No, according to your chart this is the range where you fall :5’7″ – 5’11” = 16 – 17 inches frame size.
I am 158 cm height with inseam 73, what is my MTB size ?
Hi Jafer,
According to our chart, you fall under the 15” / 16″ range which is categorize under small.

Hi Don,
You can get a 26′ tire because that’s common. You also need a frame size that between 15” / 16″ under the ‘small’ category. I would suggest you also need to get a proper bike fit to avoid future discomfort.
Help me buy my bike please
Juleshet
Hi Jf,
What type of bike do you like?
Hi. My height is 164cm and inseam is 78.75cm. Looking for road bike — racing style/aggressive with short wheelbase. What size frame would you say would be best for me. Also I am a female and have decently long arms. Sizing charts and methods always fit me in between sizes and it’s hard to tell since they’re geared towards males.
Hi Keara,
You should be ok with bike sizes suited for riders around 5’3″ to 5’6″. These are under the small category. Make sure to look for frames with 51-52-53 cm sizes. Read my review of the best road bikes of 2020 here.
I am 5′ 5″. I am thinking to buy Jamis trail x expert. The store has only 15″ frame (small). From the chart, I can either use small or medium frame. Jamis has only frame size of small (15″) and medium (17″) and does not have 16″ frame. Is it ok to use small frame or medium frame in my case?
Hi Jehen,
You can choose 15″ and it will fit you perfectly.
Looking to get new bike for my 13 year old. He’s already 5ft 6 and still growing. So wondering if a 17” is best option.
Hi Tricia,
Well, if he is still growing then it is safe to get that size. Cheers!
Im 5″7, -5″ 8 and i was looking at a large road bike stating 5″9+ , can i still buy this bike since its a good deal and nice bike?
Hi Shabam,
I don’t think that is a good idea. That is why we have bike sizing charts and bike fit. You need to stick with your recommended size.
Hi Shabam,
Just make sure it is categorized under “medium”. You should be ok with sizes of 16” / 17″.
hi sir,
looking for a 29er size, im 5’6” feet at 80 kls.
small,medium for a 29er mtb hardtail?
thank you
Hi Geraldo,
Go with medium. Cheers!
Hi Geraldo,
It should be medium.
Hello
I am 5’9″ tall and my inseam measurement is 31″. I got a Cannondale synapse road bike on sale from a 3rd party and did not see the measurement. After I started riding, I measured the frame and is 51 cm. I don’t feel uncomfortable riding it but should I increase the saddle height to make it most comfortable. What is the optimum size for me in a road bike / City bike
Please advice
Hi RX,
The optimum size for you is between 56-57-58 cm under the “Large” category. But then again, our bodies are built differently. You can try doing that to the saddle height to see if it works.
Hi RK,
It is too small for you. Get the one that’s right for your size, which is large: 56-57-58 cm.
Hi. I just sold a bike that was too big for my height. I’m 5’1 with an inseam 28. It looks like I need a small or extra small. I just want a hybrid. Looking at a Liv Flourish 4, but not sure on size. Any suggestions?
Hi Annette,
You need a frame sizes between 13″ to 14″. Yes that falls under extra small.
I’m 5’3 female looking for a mountain bike. What’s the best tire size and frame size for me?
Hi Ammu,
You need a small frame, between 15″ to 16″.
Hello,
I’m looking to buy my first road bike. I’m 5’10” with a 30” inseam. The two sizes I am deciding between are 54cm and 56cm. I currently ride a 53cm track bike which feels good. I’m just concerned that the 56 is too big but most size calculators suggest 56cm. Thanks in advance
Hi David,
Yes you should be ok with size 56. This size should help prevent discomfort during long rides.
Hello im looking to buy a new bike from amazon
My height is 5-10ft or 178cm and bike measurement is this

Frame size 22 inches
Material type Aluminium
Number of speeds 22
Suspension None
Wheel size 700 millimetres
Included components bike
This is a road Bike do you think that would good size for me
let me because i’m eager to buy it 🙂
Hi Aris,
As long as you don’t go beyond the 56-57-58 cm frame sizes and you should be ok. Beyond that is too big for you. This frame is too big for you.
Wow! You’ve really got a lot of great info here! I only wish I had read it before I bought my Journeyman. I’m 5’8, 5’9 with shoes😁, with a 30” inseam. I probably should’ve bought a 54”, but the store only had a 55.5” and with the bike shortage right now, I thought it would be fine. I replaced the handlebar stem with a shorter one and the seat is set pretty low. The bike feels good riding, but when I straddle it, the bar comes right up to the crotch flat footed. I can probably return it, but it would be a huge hassle (I drove about 3 hours away). Would you consider this bike fine as it is? Or worth trying to get a smaller size? Thanks!
Hi Rob,
If it feels good while riding then that should be ok. We all have different body measurements regardless of the similarities in height.55.5 is for someone who is already 5’9. It is worth trying to get a bike your size if you can. But, you can make other adjustments like the fore & aft or saddle angle. Get the feel of it and listen to what your instinct is telling you.
Thanks for the reply Jeff. Good advice. Still experimenting with the saddle.
Hi Rob,
You are welcome. Just remember, a millimeter can make a difference in comfort.
What does 700c stand for in bike size. I’m 5’7″ with 32 inseam and I’m looking at a 28 inch 700c.
Hi LaShon,
Let me quote from http://www.centurycycles.com
“700C tires
The modern standard for road, cyclocross, and many hybrid tires is 700C. You’ll also find 700C tires on some European-style cruiser bikes.
The “700” refers to the rough outer diameter of the tire, although the actual outer diameter will vary greatly, depending on the type of tire and tread pattern. The “C” means NOTHING; it does not stand for “centimeters.” Think about it–a 700-centimeter tire would be HUGE, over 21 feet tall! And don’t say “700CC” unless you want to look like a complete newbie. For the origin of the term 700C, see “A Brief History of 700C” below.
The BSD of 700C tires is 622mm.
Most high-performance road bike tires have a width of 23 or 25 millimeters, although some are as narrow as 18mm or as wide as 28mm. Cyclocross and touring tires range from 28mm to 38mm (although the maximum width for officially-sanctioned cyclocross events is 32mm), and hybrid bikes use tires 35mm to 45mm.
You’ll find the size printed on the side of most tires, e.g. 700Cx28. Sometimes, the manufacturers will put the “C” after the width number, e.g. 700x35C, leading some people to incorrectly read it as 700×350, which again, if correct, would be a HUGE tire!
To make matters even more confusing, sometimes the size is printed on the tire as the width followed by the BSD, e.g. 23-622.”
Better get a medium frame between 54-55 cm.
28c is good for gravel riding.
Hi I’m a 5ft 2 female looking for a road bike. Size small in the women’s bike I’m looking at ends at 5ft 3 but I just can’t get hold of any. A mens size small starts at 5ft 3, would this be too big for me?
Hi Sarah,
I don’t think so but you need to get a bike fit to ensure comfort. Recommended frames are based on your height.
Hi, where does a beach cruiser fall yo, category? I’m 5’ 5”, i want a bike without gears to mess with
Hi Dawn,
It falls under ‘comfort bikes’ due to its geometry. A single-speed beach cruiser is something you might probably want to check. Look for a 16” frame listed under ‘medium.” More on our commuter bikes here
Hi,
I’ve been looking for a new road bike. My bike shop is helping me but I’m a bit confused so thought I’d ask your advice. I’m looking at a second hand bike for not much money. My bike shop stated I’d need a 56 frame (I’m 5’10”). I saw him today and he had an old Montana road bike come in. He’ll do it up for me for 220 euros. However, on the frame it’s got 52 written on it. He showed me how he measures the frame and compared it to a 54 frame (on a trek road bike) to show how the bike for me is actually bigger. He seemed to dismiss the fact that 52 was written on it. I took it out for a spin and it seemed ok, but what do I know? This guy is well known here in the area of Flanders where I live and I’m a bit confused… whats your advice?
Thanks in advance,
Mike
Hi MIke,
While it is true everyone has differences in body structure, it is best to rely on standard charts that have been around for a long time. This is to avoid future discomfort. There are bikes who seem to be ok at first or second spin, but after a while you’ll notice a growing series of body aches and pains. The frame sizes that should be ok with you are: 56-57-58 cm. These fall under the large category. 54 is medium.
Im 5’5 in height and 64kilos.
What is the best size for me? Do i get size 16?
Hi Windle,
Yes size 16″ is perfect for you.
Hi im 6ft tall. with inseam of 32. Is there any way of me pulling off riding a 55 frame comfortably?
Hi Abel,
No, there is no way to pull that off. Even if you make seat post or stem adjustments, the size will create future discomfort. Remember that every centimeter counts. You should choose frames with 58-59-60 cm sizes and these are under XL.
Hello
Looks like I will need a 21 inch frame. I am 6’4.
Is there any consideration about wheel size for a 21 inch frame ?
I will be buying a mountain bike for street and bike path only.
Thank you.
Hi Mike,
Yes, 21″ will be ok for you. That’s under the XXL category. The 27.5″ is the populate choice these days. You can also get the 29″ if you want to cruise rock gardens smoothly.
My hight is 5’8 feet what size of bike should i buy?
Hi Mulmi,
Get a frame between 16” / 17″, under Medium category. Cheers!
Hi, I currently ride a size 56 road bike but looking to upgrade, I’m 5’10 with 34in inside leg measurement. Should I be looking to buy the same size again?
Hi Gemma,
Yes. You should get something that makes you feel comfortable on the road.
Very informative article. Where would a small folding commuter bike fit (16″ or 20″) wheels fit into the sizing system please
Hi John,
It is categorized under City bike/ Hybrid commuter types. Note that the standover height of the bike is not really crucially affected by wheel choice.
Hi, I’m 5′-10″ with an inseam of 31.5″. Looking for a road bike, would 56cm frame work or should I go down to a 54″ frame?
Am looking at a used 56″ frame that I love, wondering if I could make that work.
Hi Michael,
You fall under these range: 56-57-58 cm otherwise known as Large. No, 54 is too small for you.
Hi Jeff, great article!
However the sizing for hybrid bikes confuses me here. Is this also for drop bar gravel bikes?
First off, I am 1,89cm (~ 6’2″) tall with an 87cm inseam (~34″)
I’m looking for a Kona Rove ST but my size chart on the website is right between 56 & 58.
For gravel bikes, would the smaller size be easier to fine tune to my correct size, or the larger frame size?
Also I have heard, that Kona bikes size larger than others. Your input is appreciated.
Best regards,
Jan
Hi Jan,
Thank you! Gravel bikes still fall under road bikes and are using the same measurement system. Yes you still fall under 58-59-60 cm otherwise known as XL. 56 is too small for you.
Hi Jeff,
I just bought a used 2012 Motobacane 29er, it is a 21″ frame. I’m 6′ with a 33.5″ inseam. For light trail riding do you think this bike is too big?
Thanks for reading.
Jon
Hi Jonathan,
No. It is just perfect. Do take note of other factors like saddle fore & aft, saddle setback, stem length etc that may influence riding comfort.
Jeff,
Thanks for the info. I am wanting to order a Canyon and where I live is almost impossible to test ride (MI) I am looking for the inflite and it is saying with my measurements 178cm height and a 82cm inseam that I am a small. I ride a 56 (lg) diverge and it feels great, seems crazy to go down two sizes. I get the more aggressiveness of a cx type bike in lieu of a gravel. Do you have any experience concerning the canyon sizing?
Hi Shane,
I don’t know where you are basing the sizes but here are the actual measurements : 5`9″-6`0″ 178-185 cm(this is where you fall under. So, we are looking for a frame size between 17″ / 18″, under Large.
According to all of the size methods, I would get a 15-16” frame; however, I’m only finding 14” and 17” frames available. Which size should I order. I’m 5’5” with a 30” inseam. Thanks!
Hi Vanessa,
That’s the problem with ordering bikes without a proper bike fit. Is there a way for you to return the bike when it doesn’t fit you? Getting a smaller frame might create discomfort in the long run.
Hey Jeff,
I’m looking at the 6KU Single Speed but unsure on sizing – 55cm & 58cm frames
My dimensions:
Height – 183cm ish
Arm Span – 190cm ish
Inseam – 83cm ish
Hi T,
Choose the 58cm frame size. This is under the XL category.
Hi Jeff! 🙂
I’m looking for a hybrid/city bike. My height is 5’5” with an inseam of 27.5. I saw one chart (height only) said a 15-16 inch bike was keen. On another chart I saw that my height and inseam calculated to 18” I’m not sure which way I should go to chose the right bike. I found an affordable used bike but it’s 24” is that too big? Your input is greatly appreciated. Tyia
Hi Amy,
You will be ok with the 16” under Medium. 24 is too big for you.
My hight is 5.11 inch
Whats a best size for me
Hi Azeem,
Get a 19″ frame. Cheers.
Hi. I am 6 ft 6 in with 37 inseam.
HELP?
Hi Gary,
You need a bike which is 21+ inches.It is already under XXL.
Hi Jeff Thanks for the article
Im 5′ 8” male 30 inch inseam and im looking at commuter/city step thru bike that comes in size S/M 17.5 inch frame with 26” wheels and M/L 19” Inch frame with 27.5 inch wheels I cant decide between the 2 sizes.
Hi James,
Actually you fall in the 16” category which is medium. The former measurement you have also works. Don’t go bigger than those.
Hi,
Thank you for this article, really helpful! My height is 5’4″ with an inseam of 28″ and arm length of 68″. Wondering which road bike frame size you would recommend?
Hi Cody,
Get a ‘small’ one, somewhere between 51-52-53 cm.
Hi Jeff,
Interesting read.
I am trying to get my girlfriend into riding – in her 40’s and hasn’t been on a bike since this summer. She started using her daughter’s but it is an XS frame Trek mountain bike. I’ve been telling her I think it’s too small. We have started to look at other bikes and looking at a dual sport that the handle bars are slightly higher. For one of the bikes we are looking at trying to choose between 15″ and 17″, would either size work or would one be more suitable than the other?
She is 5″7″-5″8″ with an inseam of almost 31″ (30 3/4).
Any feedback is appreciated. Thanks… Jim
Hi Jim,
Wow that is too small. She should be ok with 16” / 17″ frame which is under ‘medium.’
hi,
looking at a carrera crossfire 2 hybrid bike.
6ft tall with an inside leg of approx 33 inch. Getting conflicting recommendations of as low as 17/18 inch frame upto 20-21 inch! HELP! 🙂
Hi Alex
Good question! The reason why there is no exact number is because no two people have the exact measurement. But the range can give you an idea where you should be, and not to go under of over that range. You should be good with the 17 – 19 inches range. Other factors like stem length, saddle height, fore & aft can contribute to the comfort.
hi, great article,
currently looking into purchasing a carrera crossfire 2 hybrid – 6ft on the dot in height and a inside leg of around 33inch. Would the medium (18inch) suffice? states for heights between 5’8 and 6’1
Your expertise would be appreciated 🙂
Hi Alex,
Yes that is still within the range!
I am 5 ft with an inseam of 27 and my husband is 5.5 with inseam of 30. we are looking for an easy mount bikes. What would you recommend and what size
Hi Dora,
For you, a frame of 14″ (XS) is good for you. Your husband will be ok with 16” / 17″ (M) frame.
I’m 5’9.5”, 2ft 8inch inseam, what size road bike should I get
Hi Liam,
You will be ok with the frame sizes 16 – 17 inches.
I found an XL frame road bike, and I feel most comfortable on it compared to a medium/large one, but I’m only 5″8?
Hi Pranav,
No two people have the same body structure. Trust your body and not simply base on standard measurement. If it feels good then that should be OK. There are a couple of things that can contribute to the comfort like the saddle height, the stem length etc.
Hello,
I am about to buy a new roadbike with a very classic steel frame geometry and I have two choose between 56 cm and 59 cm frame size. I can’t test it before ordering, so I am a bit unsure which one to pick. I am 182 cm which makes me think 56 could be enough, but with my inseam of 87 cm and arm span of 190 cm the 59 could be just doable although it sounds a bit high.
Many Thanks!
Florian
Hi Florian,
You fall under the large category so these measurements are still good for you: 56-57-58 cm (L) Yes 59 is beyond your range.
I am trying to figure out what kind of bike to get. I’m 5’ and I haven’t been in a bike for over 20 years. My little ones just learned how to ride and all are insisting I join them. Any suggestions on what I should look for? Thank you in advance!
Hi Cheryl,
You can look into the hybrid category which is friendly for your body and riding condition. Choose a frame size under 14” (XS). Check out my post about Hybrid Bikes.
Hi there. Can you tell me what size electric bike size is best for me please? I am 5′ 9″ tall with a 31″ inseam.
Thanks so much!
Lisa
Hi Lisa,
Those under 16 – 17 inches should be good for you.
Hello
I’ve just bought myself a junior mountain bike with 24″ wheels. I am 5ft1 with an inseam of 27″. I have raised the seat as I felt I was sitting too low. I’ve been on a bike ride today and feel like I’m struggling so much. Also when I turn the wheel, it’s scuffs on the front of my shoe. Causing me to go off balance. Is there anything that I can do to make it more comfortable? Or should I return the bike and get a different size?
Many thanks
Stacey
Hi Stacey,
It looks like the bike is not the right size for you. Did you get a bike fit? It is very important. For your size, you need a frame size between 15” / 16″ under ‘Small’. Below or above that will cause discomfort.
Hi Stacey,
Bike comfort has something to do with the frame size. Choose a frame with 15” size and this is under the “Small” category.
Hi. I am 5’2. What size bike should I get? Looking for a road bike.
Hi Chancey,
Look for a frame size between 49-50 cm. That’s under XS(extra small).
I am 6’3 and 88cm inseam. Want a bike which i can run in city and also work for my fitness. Which one and size you suggest
Hi Vijay,
I’d go for a frame size of 19″ under XXL. Try a commuter or City Bike.
Jeff,
I would like to start biking for fun with my son and for exercise. I will be riding on roads, bike trails, and gravel travels. I am 5’7 and my inseam is 32. I am currently looking at a used Trek hybrid bike with a 17″ frame. Do you think 17 is too big and should I stick with 16?
Thanks so much,
Jennifer
Hi Jennifer,
Yes stick with 16” which is Medium. 17″ is too large for you.
Of 3 measurements 2 say I need 17″ yet another 1 says I need 20″. Now I am still none the wiser
Hi Ifc599,
It is just a recommended range for your height. As long as you don’t go below or above the range then you will be ok. Remember that there are other factors that add to bike comfort like: seat angle, height, and handle bar position/length.
Jeff can you help me out please 🙂 I’m looking to start cycling , I’m 6,2 ,11 ,5. Stone can recommend inch bike ,I don’t know what s to small or big.
Hi Jason,
For your height of 6’2, choose a frame between 19 – 21 inches. You are under XL. Great to know you are going for the healthy lifestyle.
Hi, I’m 177cm tall and I’ve got a 80cm inseam.. Which size Merida Scultura 4000 would I buy if i’m gonna use it in races?
Hi Daniel,
You fall under the large category. You should be ok with sizes 56-57-58 cm. Good luck on those races.
Hi Jeff,
My height is 5.11 ft and weight 90 kgs. What size of bycycle do you recommend 24 or 26.
Hi Abhishek,
Your height translate into these compatible frame sizes: 56-57-58 cm, under Large category.
Hey, I’m 6’4” and am looking for a mountain bike or road bike. What size dream should I be looking for in each category?
Hi Jo,
You belong to the XXL category. For road bikes you look for these frame sizes: 61-62-63 cm. For mountain bikes, these: 73-86 cm 19″ +, under XXL.
Hello Jeff,
Wondering if you can please provide your professional guidance. I’m 5’8 and weight 178 pounds. Which mountain bike will best fit me? 24″ or 26″?
Thank you for your time and help!
Hi Hector,
if we base your height on the standard bike size chart, you fall under the frame sizes of 16” / 17″. This is classified under “medium.”
Hi Jeff,
I want to learn to ride a bicycle and would like your help to pick the right size/type, please.
I am rather tall, curvy woman- 5ft 7″ tall (170cm) with 34″ inseam (86.36cm). I would like to ride for pleasure while having some work out going on in the process.
Please advise. Thanks
Hi Debbie,
If that is the case, then you should pick up a city bike/commuter type of bike. You can also look for hybrid bikes. The suggested frame size for you is size 16”
Hello,
I’m Arman Chermakyan. I am very new to biking. I’m trying to look for a bike that can handle both well on the road and on the trails. My height is 5’11. What size bike is best recommended according to my overall height?
I really appreciate you letting me know!
Sincerely,
Arman Chermakyan
Hi Arman,
A hybrid bike sounds like something you should consider. Look for the Large category which fits your height. Check out my post about Best Hybrid Bikes or you can also try and see if Gravel BIkes work for you.
WOW! sizing is obviously very complex seeing all the comments. I’m looking to upgrade my bicycle. I have a 20 year-old very heavy ‘beach cruiser’. I’m looking at buying a Hybrid. I’m in pretty good shape but live in a very hilly town. I’m 5’9″ with a 37″ inseam (yep, long legs), weigh 150lbs. My current bike has 26″ wheela & the seat is at 38″ from the ground. What size of bike should I be looking at? The charts don’t really cover my height/inseam.
Hi Siobhan,
Look for a hybrid bike with 17″ frame. You also need to consider seat adjustment like the fore & aft, height and also angle. A cm can make a big difference in terms of riding comfort. Check out my post about Hybrid Bikes.
Hi Jeff,
Haven’t ridden a bike since I was a teenager so really nervous about riding again,but something I have thinking about doing recently. Really need to start thinking about my health and getting some exercise as I’m about to hit 50 !
So really looking for a type of bike or any kind of recommendation . Can you help ?
Hi Karen,
It is good to know you are thinking of your fitness. A hybrid bike will be a good choice for you because of its comfort and also stability. Check out my post about Best Hybrid Bikes.
Hello Jeff,
I am a male adullt with a height of 5’3″ with a bare feet in-seam length of 30″. I have zeroed in on buying a mountain bike of 14″ frame size. Can you please advise, if that’s the right size? The only other frame sizes available are 17″ and 20″ for the model that I am looking at.
Thanks and regards.
Hi Anil,
Something around the size of 15” / 16″ is good for you. That’s under ‘small.’ Anything smaller or bigger can cause discomfort in the long run.
Hi
My height is 167cm and inseam leg 76 cm. i have a road bike on size 52. should i to try on size 50 or just change a position of the saddle? should i upgrade stem to a smaller one? . i bought online so i didn’t fit the bike.
thanks you so much.
Hi Charol,
Size 50 is already extra small (xxl) so 52 is ok. You can get a shorter stem and also adjust your saddle fore & aft to give you better comfort. Here’s more on saddle fore & aft
HI,
My height is 155cm and inside leg 74cm. I have a 14 inch frame with 24″ wheels and it feels too small. would a 14″ frame with 26″ wheels be any better? I have tried a few 16″ frames which are just too big, cant get my feet down. I don’t want to make another mistake, especially ordering online.
Thanks so much, any advice appreciated.
Hi Dawn,
You should be OK with the current frame size that you have. If it feels too small, try adjusting the saddle height. You can also try to upgrade to a longer stem.
My son is 10 years old and he is 4’7. Would a 24′ bike be good for him? Or should we go bigger?
Hi Shahid,
A 24″ is just perfect. Cheers!
My wife is 4’11” and has a 25 inch inseam. What size beach cruiser should she get?
Hi Jim,
Get her a 14” and that is under XS(extra small) frame.
hi!
I’m 6’0 tall and am looking for a bike that will do well on bike trails and casual riding. I don’t know what size I am and want a bike that will last along time!
Hi Claudia,
According to our Bike Size Chart you need a frame between 17 – 19 inches. Now, you can also check our Best Hardtail Mountain Bikes to see if this is something that will work for you.
Hi Jeff,
I just bought a hybrid with a 20” frame. I’m 5’6 and although this bike is deemed too big for my height, I’ve lowered the seat all the way to make it comfortable. I want to ask, why is it that my recommended road bike size is 52cm; and while 20” is equal to 50cm…would that mean that this hybrid bike is actually my correct size?
Hi Jake,
For your height, you need a frame from 15 – 16 inches. Now that’s size ‘small.’ So that hybrid bike is not your size. You should not get a frame size larger than 51-52-53 cm. It will give you discomfort in the long run. Remember that that basis for bike measurement is different. You got 58-59-60 cm which is for XL.
hi I’m 5’8” in height and my wife is 5’1”. we intend to buy one bike, can you recommend a frame size that we can both fit in?? thanks
Hi Andrew,
A frame between 16 – 17 inches is a recommended size for you. For her, it’s 13 – 15 inches. It is impossible to get a ‘one size fits all’ kind of bike because it will cause physical discomfort in the long run. I suggest you buy two bikes with recommended sizes.
I’m 6’5 what size bike should I get, just something I can ride with my family.
Hi James,
You need a bike that’s 21+ inches. You can also check my Best Hybrid Bikes post to see if this is something you’ll like.
I am 6’0” and am working on getting my weight under control. I want to start riding but I have no clue what type to get that is budget friendly. I literally just want to be able to go out and ride a bike for exercise and maybe get something higher end if i take to it. Also does my weight help determine the size of the bike or is it simply my height?
Hi Mike,
It looks like you need a hybrid bike for your riding. Hybrids are easy on the body and they can help you with your weight loss. Check out my post about Best entry hybrid bikes For your height you need a frame under XL. Somewhere around 18″
Very insightful article, thanks for all the tips. I have a more complicated question. I have a rather weird body, longer lower body and arms and shorter upper body or chest. I am roughly 5,8 when I stretch then 5,9 around that. My inseam length of my leg is 85Cms, I should have a 58 cms frame which I ordered and unfortunately the frame is too long for me. it can fit my legs and arms and all but because my upper body is short its too long. I have to send the bike back and now am bait confused ordering another bike online if I should go with 56 cms in relations to my height or I order a 54 cms frame? Whats your opinion on this? Please note that I adjusted the seat and this was already not helpful on the 58cms frame bike.
Thanks a lot.
If I may add on to this, am trying to buy a Gravel Bike. I also wonder if you have any recommendations where one could buy bikes online a reputable site to check out for Gravel Bikes.
Hi Martin,
Please check my Best Gravel Bikes post before buying. These are the best in the market, so far.
Hi Martin,
Yes not everyone has the same body structure. Try to make an adjustment with stem length and handlebars. There are small incremental adjustments you can so and they can affect your riding comfort. You can still go with the 56 provided you shorted the stem a little bit. You can also adjust the saddle fore & aft which can impact the comfort.
I am 5’2 ,115 lbsand haven’t ridden a bike in ions but I’m not in bad shape. I want to purchase a bike not too expensive, but willing to invest a bit. My udea is to ride on the streets, but maybe also on trails in Gettysburg on trips. What kind of bike and size would you recommend.
Hi Carrie,
I think what you need is a gravel bike. Gravel bikes are the trend these days and you can use them on flats and off road. Check out my post on Best Gravel Bikes
I’ve read through the sizing info but still have a question. According to my height (5’3″), I should be looking at a seat tube of about 15″. But, according to my inseam of 29″, I should be opting for a 20″ bike. What does the 20″ refer to?
Hi Steve,
20″ refers to wheel size. They are associated with small bikes or kids’ bikes.
I am 180 CM and when I placed my order on L frame Silverback 29MD it turned out to be out of stock and the shop is offering the XL frame instead, do you think I should take it? I fear that it will be too big
Hi Ahmed,
“Large” is the right size for your height. Yes, you can make little adjustments like the seat post height and stem length etc but, I would suggest you stick to recommended frame size to avoid discomfort in the future.
Hello trying to buy a bike for my 13 year old. He is 5’4 and has a 28 inch inseam. I was thinking a 26” bike with 18” frame. Is that a good size? I’m worried it’s too big but I know he will grow so I was thinking I would put the seat as low as possible. Please help
Hi Melissa,
Yes, a 26″ bike with 18” frame is a good size! Remember that other factors such as seat height and handlebar adjustments can add to the comfort.
Hello,
Thank you for this great information!
How much does wheel size matter? I have a lot of 24 and 26 inch options, and don’t know whether it makes a difference.
I’d like to purchase a mountain bike for my daughter, who is tall for her age (she’s only 11) and still growing. She is 62in tall, with a 29.25 inseam. Based on your article, I figure she needs a 15-16inch frame, but what size wheels?
Thanks so much,
ORJ
Hi ORJ,
It doesn’t really make a difference. You can still adjust the bike for comfort in terms of seat post height and angle. Cheers!
Thanks so much! One more thing (that I should have made explicit I was concerned about): is a 15-16in frame sufficient, or should I get an 18in frame to account for the fact that she’s not done growing yet (and likely to be pretty tall, as her father is 6ft and I’m 5’10)?
Hi ORJ,
Yes, 18 is a safe bet since she is taller than most of the girls her age(and still growing). You can just make micro adjustments with the seat and saddle. Cheers!
Hi. I would like to buy a bike for my 14 year old daughter. She is 5’4 with running shoes on and she has a 29” inseam with no shoes on. Since we are not able to go and try out bikes, the store I called recommended a 16” frame on a EVO Swift Ridge 5 commuter bike with 27.5” wheels. My concern is that she will out grow it too quickly. Would it be a big mistake to get an 18” frame and lower the seat as much as possible. I appreciate your help! Stay Safe!
hi Steve,
That sounds like a good idea too because she is growing up as you mentioned. Other factors that can contribute to comfort are seat post height, handlebars etc. You can make minor adjustments for comfort 🙂
Hi
I am after an MTB. My height is 171.5cm, inseam 76cm and arm length 56cm. I am in between sizes (small/medium). Should I go small?
Hi Vishal,
That is a good question. You should go with medium. There are factors that can add to your comfort like stem length and seat height. Check out my post called Bike Size Chart
Wow this has been the most in depth and helpful guide I have found! I am so thankful. So thank you! You have made it so easy to understand and now I’m excited to go find the perfect bike for me. I am armed with basic knowledge to purchase a bike to suit my frame.
Hi Jer,
Glad you find this site helpful. Cheers!
Hi I’m 13 years old. I’m 5 foot tall with a 29 inch inseam.I’m not sure what size bike to get. I don’t know if I’m looking for frame size or tire size the guy at the bike shop talked a lot about both and I’m confused. I want to mountain bike or kind of like my dad says a hybrid because I also want to ride in the roads with my friends
Hi Shaun,
The ideal frame size for you is between 15″ to 16″. Please refer to our Mountain Bike Size Chart for details.
Now before buying your bike look into our Best Hybrid Bikes and Best Hardtail Mountain Bikes so you’ll have an idea what you really like.
Hi Jeff!
I’m in the market for a bike, the first one in A WHILE and am overwhelmed by all the choices.
I found one that I’m interested in. It is a Schwinn’s Women’s Hybrid bike. 15″ frame with 700c tires. I am 5’1″ with an inseam of about 30in.
I was looking for a bike with 26″ wheels, as I felt this would be better. I can’t try this bike because we still can’t go into stores, so I would be purchasing online and then (because of COVID) I cannot return it.
What are your thoughts on this?
Hi Victoria,
Please check out my post about Best Entry Level Hybrid Bikes for helpful ideas. You fall under the small category with a recommended frame size of 15”
Always chek out Bike Size Chart if in doubt. Goodluck!
Hi, thanks for great explanation. I have weird measurements here! although I always knew I have really long legs and arms but it doesn’t make sense now
I am female, 5’7″ with 81 inch (32 cm) insim. Is my bicycle size medium or large? I am more inclined toward medium. What do you think?
Thanks in advance
Hi Nikka,
You generally fall under the medium category. You also need to consider other factors like stem length and saddle height/positioning. For example:
Saddle fore & aft: Move your saddle to the front or rear
Stem length: Buy a longer or shorter stem. It changes your body position
Seat height: Buy a longer seat post
Hi, I’m 15, 176cm tall and I’ve got a 80cm inseam. Which size road bike do you think fits me well??
Hi JD,
You fall under the large category. Suggested frame size: 56-57-58 cm

Hi
I’ve purchased a carrera mountain bike (22inch frame) but am only 5ft 11. Not really thought about it at the time but now looking at online reviews it seems that for my height it’s a large however i weigh 250 pounds hence I went for the xl size. Would it still be possible to ride a xl frame? Is there any changes I could make instead of sending the bike back? Any help is appreciated.
Thankyou
Hi Bakr,
A bike with a wrong size can cause issues. More here If it is the wrong size then you have no choice but to send it back and get the right one for you.
Hi,
Looking at the sizing for Road Bikes one size says I’m definitely size L – as I’m 5’11 (181) however my inseam measure is 80cm with says definitely size M (54 cm). Given it’s now a little difficult to buy in store and I can only order online what would be your recommendation ? M or L?
Hi Omri,
Yes you fall under the large category. There are also factors that can affect your riding comfort. They are : saddle height, saddle fore & aft, handlebar length, stem length etc. More here
I’m 16 years old and I’m 5’7 would a 56cm frame be too big for because I’m unsure of what frame size I should use because my current 42cm frame and it is too small I’m wondering what size if I can ride a size 56 or not?
Hi Enrico,
Welcome to the cycling community! Always refer to our Bike Size Chart when getting a new bike. There are charts for road bikes, mtb and city bikes. Choose the one you need.
Hi there. If you wouldn’t mind, I’d like to get your thoughts on a bike size for me. I’m 6’3″ with a 85cm inseam. I’m thinking of buying a GT Grade Carbon Pro (geometry: https://www.sefiles.net/images/library/features/G20_geos_grade.jpg). I suppose I should get the 61? What do you think?
Thanks for your help and your wonderful site
Hi SB,
Your height falls under the XL bracket(58-59-60 cm). 61 already belongs to XXL. In cycling, centimeters can make a huge difference in comfort.
More here Bike Size Chart
Remember that frame sizes from XXS – XXL don’t have the same meaning for every manufacturer. It is recommended to have a proper bike fit.
Hi! I am a 5’10” woman with a 35” inseam. Yes, I am half legs. I recently tried a bicycle that fit my legs but I could barely reach the brakes. What do I choose? Smaller frame with a super high saddle height or larger frame? Looking for a road bike or possibly a hybrid.
Thank you for any input!
Hi Lisa,
You fall under the large category. However, there are factors that can affect bike comfort like stem length, saddle fore and aft, saddle height etc. Be sure to look into these things during the bike fit.
Hi, I’m 6ft (183cm) tall and have an inseam of 32in (81cm) Should I be going with a large or XL for a mountain bike? Thanks.
Hi Chad,
Either way will work for you. Just remember that saddle height, saddle fore & aft, stem length and other factors can influence your riding comfort. Please refer to our Bike Size Chart
Hi, I am looking at gravel bikes and love the OPEN U.P. On their site they list that for a rider with height of 188-201 cm would be XL. I am 198cm tall with an inseam of about 98 cm. Would you say XL would fit me?
Hi Leolo,
You are quite tall. Your height would fall under the XXL category when it comes to bikes. Please refer to our bike sizing charts for proper fit as we want you to avoid any back pain from improper fit. Scroll down to Road bikes in the Bike Size Chart
My leg inseam is 30″ however I’m 5’8″ only because I have a long torso… So should I go 15″ because of my leg inseam or 17″ because of my height?
Hi Jessica,
Physical differences in shape and height should be taken into account when choosing the right bike. By standards, all sizes should depend on the height but for your safety it is best to have a proper bike fit. Please refer to this chart for guidance: Bike Size Chart Remember that comfort depends on many factors like saddle height, handle bar stem, saddle fore and aft etc.
Hello Sir Jeff Balton
Im 5’9 tall i might get confuse which bike frame size should i buy?
Is 27.5 x 17 medium size or
29er ?
Hi Projie,
That is a good question! It looks like you fall under the Medium category as indicated in
Hi Jeff, thank you for sharing your knowledge,
I am 35, 5’2″ and 55 Kg, what bike and size should i buy ? I am scared to buy anything online currently as i am not sure of size or type of bike i should get. I am looking for some easy and comfortable options. I don’t want to go high end mountain bike neither very expensive ones. Do you recommend geared bikes ?
Thank you
Hi Chandra,
Based on your height, you need a bike with 15” / 16 which is on the Small category. Use this link as guidance and scroll to Mountain Bikes: Bike Size Chart – How To Choose? 5 Easy Methods
Hi Jeff,
I am 50 years old and I have a road ML Giant road bike. whenever I ride my bike, I have some problem with my hands. After sometime riding my hands go numb and I think it might be because the size of the bike.
I am 176 cm (5′-9″) tall and my inseam is 82 cm (32″). I usually ride between 15-20 miles per day. Could you please help me to find the right size bike.
Thanks
Hi Mohammad,
For your size, between 5`5″-5`9″ or 168-178 cm, you need a size between 16” / 17″ which falls under Medium. Beyond or below that can cause issues. You can also refer to our post about Bike Size Chart here: https://www.bicycle-guider.com/bike-articles/bike-size-chart/
Make sure you get a proper bike fit before taking the bike home. Cheers!
Hi Jeff,
Really like your article and think it is one of most useful when comes to picking the frame size but still bike industry doesn’t make it any easier when choosing the frame. I am looking for my first road bike and interested in purchasing second hand and wandering how will variation in frame seat tube length (FSTL) will impact my ride and comfort and is it really that important, and here is why.
I am 190cm with inseam length of 92cm which gives frame sizeof 92×0.7=64.4cm. Looking at the different bikes Trek Emonda ALR5 suggests frame 60 or 62 frame with FSTL of 57.3 and 59.3cm (why not frame 64 with FSTL of 61.3cm)
Canyon AL disk 8 recomends size L with FSTL of 56cm while Canyon Endurance CF8 recommends size XL with FSTL of 59.5cm. When i look and compare difference of all other frame dimensions, variaton is minimal ranging between 1 and 2cm between each frame size . I can not see how can that make an impact on my ride, please consider that I am very new in the road bike world and haven’t tested different frame sizes. Currently there is second hand XXXL bike frame for canyon with FSTL of 64.5cm and also Trek Emonda frame 58 having FSTL of 55.3cm . I like them both and would I be making terrible mistake for getting any one of them.
What would be your advice when choosing frame and specifically best frame seat tube length for my height/inseam length.
Many Thanks
Hi Ivan,
Getting the bike with your perfect fit is tricky. That is why you need to read our post about Bike Fit here.
I would suggest you also get a proper bike fit to avoid problems like lower back pain among others. Consider the seat angle, seat height and also the fore and aft of the saddle. All these things are make or break your ride.
What a great article especially during these Covid days. I want to do a cross-country tour and travel light and relatively fast so I’m thinking buying a gravel bike with drop handlebars and a geometry halfway between the aggressiveness of a racing bike and up-rightedness of a mountain bike. Seems I have freakishly long legs. My height is 5’11” and my inseam is 34.5″. What would you recommend? I appreciate the help.
Hi Gord,
Based on your height, you need a bike size that falls between 16 – 17 inches. This is in the Large category.

Hi,
Given the current situation, I can’t take my daughter to be fitted for a bike. She weighs 105lbs., is 5 feet tall and her inseam is 28 inches. What size bike should we be looking for her?
Thank you!
Hi Susan,
I understand your concern. For her height, she needs a size 26″. You can also refer to article for help Kids Bike Sizes – Choose The Right One
Hi
Your site is a fantastic source of information. I am 170cm height and around 75 inseam. According to Ribble I am right in between a small and xsmall. What would you suggest?
Hi Chris,
Here on Bicycle Guider, we have our own standard chart for bike sizing. We all know how important it is to have a proper bike fit. Please refer to this link here: Mountain Bike Size Chart

Hi Joe,
That’s a great question! A post to help guide you with your proper road bike fit is found here: Bike Size Chart – How To Choose? 5 Easy Methods Scroll down to Road Bike Size Chart. Cheers!
Hi Jeff, i do need your advice
I am 173cm Inseam 80 cm and there is Pinarello Dogma Think2 65.1 available on the market with size 50
Do you think it will work for me?
thank you
Hi Brian,
I get your enthusiasm for getting a road bike. However, proper bike size is necessary. Please refer to this link for guidance. Bike Size Chart – How To Choose? 5 Easy Methods Scroll down to Road Bike Size Chart. Enjoy!
I’m looking for bike for casual riding / excercise sometimes in the city sometimes off road.
I’m 5-7 height and leg inseam at 29 inches.
What do you recommend (type of bike and size)
Hi Roy,
If you are doing both road and off road riding, then a gravel bike is good for you. A bike size with 54-55 cm (Medium) is good for you. Check out our best gravel bikes here: What Are The Best Gravel Bikes?
Hi Jeff,
I’m looking to buy my first bike (all of my others were when I was a kid) and I’m looking at a Trek FX 3 Disc. Per their chart I could either get a size small bike or a medium. I’m 5’4″/5’4.5″ and my inseam is 77cm. What size do you think would be best? Thanks!
As a follow up, I am female and looking at the women’s bike: https://www.bicyclevillage.com/product/trek-fx-3-disc-womens-366053-1.htm

Hi Leslie,
A proper bike fit is important. Please refer to our correct bike sizing based on your body size here: Bike Size Chart – How To Choose? 5 Easy Methods
Hi Jeff, Thankyou so much for the help in this time when no stores are open.
I have one question, by your calculations I would need a 19inch frame (which is about right as that is what my current bike is.) But the Voodoo Bizango that I am looking at comes in an 18inch or 20inch. What would you suggest going for? I am 5.8-5.9 but on the larger side also.
Look forward to your help.
Hi Paul,
A 19″ frame already falls on the XL category. Your height falls between Medium and Large. When in doubt always refer to our bike sizing chart here: Bike Size Chart – How To Choose? 5 Easy Methods. You also need to get a proper bike fit just to be sure.
Thanks for your advice but I’m still lost. I am 1m76 and my crotch is 76cm. I am stuck between size S and M. What to choose? My practice is Mtb Trail, light enduro. I want to buy an Orbea Occam 2020.
Thank you a lot for your advice.
Yoann
Hi Yoann,
If you check our Mountain Bike Sizing chart, you will notice that you fall somewhere in the Medium category. Orbea Occam 2020 has many positive reviews. Good luck! Mountain Bike Size Chart
Jeff, you’re a unique soul! 🙂 The best. Thank you! Cannondale SystemSix Di2 HiMOD 54cm on order! Woohoo! Thx!
Hi Ryan,
I appreciate your enthusiasm! You are welcome. Best of luck!

Hello,
I’m looking to get my soon to be 11 yr old son into riding, he’s currently 56″ in height , do you have any suggestions for a proper road bike to start ? I’m concerned because there isn’t many choices for kids road bikes and it appears i would have to get him into adult / female size frame. Would a 47cm be a good starting point? i just pray he doesn’t hit a growth spurt within the next couple of years. I appreciate the content/info provided..

Hi Devin,
Bike size is crucial for any ride. Please check our post about bikes for kids: Kids Bike Sizes – Choose The Right One
Looking for a new kid’s bike? The Best Kids Bikes (And How To Choose Them)
Youre the quintessential expert advisor especially helpful during COVID. My target bike isnt anywhere in town…but Im set on it: Cannondale SystemSix (2019) Ultegra di2.
I am 170cm tall (67″)
My inseam is 80cm (32″)
My reach as measured from collar bone tp mid palm is 61cm.
137 lbs with proportionally long arms and legs for by body height.
I have my heart set on the above bike and have read sooo many threads by obsessive risers…and feel unsure without being able to demo.
I really want the 54cm because I plan to slam the bars down no spacers because despite my smaller torso. my arms make up fpr it.
I’ve looked at the whitepaper geometry of the SystemSix 51cm, 52cm and 54cm….and because I like a very low and foreard and aggressive position (as well an longer legs relative to height…the saddle to bottom bracket)…I am heavily leaning toward the 54cm. There are screaming deals on 54cm and also on 51cm (which seems odd for me…but I’m open to it if it’s right. All 52cm are pricier for some reason…
What do you think is best? Will a 54cm Cannondale SystemSix 2019 work for me?
So in short,
Hi Ryan, a 54cm should be a good choice. You could slam it and extend the reach if you’re flexible enough. 51cm would definitely be too small.
Hi Jeff need a lil advice here !! I have my eyes on a road bike but unfortunately they only have two sizes 49cm and 58 cm with 700c tires
I’m 5’8 – 5’9 with 30 – 31 inseam .
Which size should I go for !???
Thanks In Advance
Hi Josue,
Thanks for your question. 49 is too small for you and will result to discomfort and pain in the long run. If you have only two sizes, 58 is closer to your body size. Remember that other factors like saddle angle, fore and aft, and even handlebar stem length can impact your riding comfort. It is always good to get a proper bike fit if you can.
Hey Jeff, I am 150 cm with an inseam of 25/26 inches. I was looking g I to 24in bikes would that be to small? What size in adults would be best. Looking at mountain bikes. Thank you 🙂
Hi Alexis, you can get a 24″ bike, but I think a better fit would be a 13″ – 14″ size frame with 26″ wheels. Some brands market these frames as XS or XXS.
Hi,
I have had trouble buying a bike in the past, and have never quite found a solution. Basically, I am 6’5″, and weigh around 148kg. I also live in Japan. I currently have a momma cherry, and when I try to take it any further than downtown it plays havoc with my arse. I’d like to go on a longer ride, so what type of bike would you recommend?
Thanks,
Joe
Hey Joe, I don’t know what the situation in Japan is regarding frame sizes, but a 23″-24″ mountain bike, cruiser, or fat bike would all be good choices. 🙂
I’m 6′ 3” and weigh 220 lbs. What size bike should i get?
Hi Jim, you should get a 22″ mountain bike or a 58-60cm road bike. 🙂
Hi there,
I am really struggling with deciding what size I actually need.
I am a grown up…. but a short one. Around 4’7” (145 cm) and 25 inch leg inseam.
Would a kids bike 24 inch wheel be too small for me?
Many thanks!
Hi Erika, a 24″ kids’ bike would be a good fit for you. 🙂
Thank you for such incredible content!
I am buying a bike for my mom online – she’s 5’6’’ about 200 pounds and looking for a light weight, easy to ride and exercise on type bike. What do you recommend? Bike, size, website, anything? I don’t know much about bikes (:
Hi Danielle, if your mom is not a frequent rider, a cruiser/city bike with a more upright riding position would be a good choice.
You can check the resources on our website for different types of bikes such as hybrids, entry-level hybrids, commuter bikes, cheap bikes, and so on, and find something you like. 🙂
Hi
Wounding if could help me with road bike size of 174cm tall and my inside leg 32inch so I not sure if should be buying 54cm or 56cm female.
Becks
Hi Rebecca, I recommend a 54-55cm size frame.
Hi,
I’m 5’11″with an inseam of 32.5 barefoot. What size road bike would work best for me? I’ve had a Cannondale R800 56cm for years and at times it does feel a little small.
Thanks,
Tim
Hey Tim, I think you’ve answered your question. A 58cm size frame should be a much better fit. 🙂
female, trying to fit hybrid with comfort in mind, ride both on and off road *leisurely*-5’6″ w apparently freakishly long legs?; 31 inseam. what frame should i be looking at? 17″?19″? I vaguely remember during my last bike shop fit them discussing me using a mens bike for better fit?…have been riding for a while but learned a lot from your site.
Hey Anne, your legs are a bit longer than what can be considered average for your height. But I think a 17″ size hybrid bike is a good choice. Men’s and women’s bikes don’t really differ that much. Usually the saddle, stem, and handlebar are different, but you can swap these easily anyways.
Hello!
I’m a 20yr old guy. 187cm tall and with a leg inseam of around 92cm = 36 inches.
My legs are pretty long so I’m not too sure what size bike to get.
My eyes are set on one(second hand though) and the seller says the size is 26inch.
Would it be suitable? I hope it isn’t a stupid question but I am very new to this world of cycling(learnt in the past few weeks on a bike meant for bike sharing apps).
Thanks for your time 🙂
Hi Ian, if you’re planning to buy a road bike, I recommend a 58cm frame. If you’re planning to buy a MTB, I recommend a 21″ size frame with 27.5″ or 29″ wheels.
The 26″ size you mention probably refers to the wheels, which doesn’t really say much. However, if it refers to the size of the frame (which I doubt), it means that the bike is gigantic and you should pass. 🙂
Excellent article Jeff, appreciate the effort. Just getting back to cycling after five years in the Middle East and online shopping is clearly the only choice given the state of the world right now. Need a bike again!!!!
I’m happy you find it useful, Steve! The current situation is less than ideal for bike shopping, but we should try to make the best of it. Have fun cycling again!
Hi
Want to buy this bike https://www.ghost-bikes.com/en/bikes/fully/bike/sl-amr-29-al-u
SL AMR 2.9 AL U GHOST FULLY
I am 186 cm but my inseam is 82cm,arms 63-64 cm
Is better M or L version of bike for me?
Hey Mexx, you should definitely get the Large (L) size. 🙂
Hello Jeff. As of now I am really stressed out. Unfortunately I am one of those people that is between sizes, I would say I am about 6’1 and have a 32in(82cm). I bought a cervelo c3 on 58cm an endurance bike which is supposed to be comfortable. I have never been somewhat comfortable on it. The top tube almost hits my crotch when.
Because of this I this I decided to buy a 56 specialized Roubaix, or a trek Emonda, and salesmen tell me to get a 58, because of my height. I am not sure if cervelos run larger than other sizes. Hope you can help me out.
Thanks!
Hi Jose, a 58cm size frame should be a good fit for you. However, your inseam length seems a bit short for your height, perhaps that’s the problem? That would mean your torso is longer than average which would affect the fit.
Both Cervelo C3 and Specialized Roubaix have detailed geometry charts available. I recommend opening both and comparing the reach and standover height to see whether or not a 56cm Roubaix would make a difference.
Good luck!
Silly question from newbie – is it ever going to work if you buy a bike with standover length slightly longer than cyclists inseam measured with shoes on? Would highly appreciate your kind response.
It can work if you don’t mind standing on your tippy-toes when you straddle the bike. 🙂 It’s definitely not recommended and not comfortable and you also run the risk of hurting yourself.
Hey Jeff,
Such a wonderful resource for people during COVID-19 when shops are shut. I’ve scanned through your comments to see if I could get any pointers on my height/inseam and appropriate bike size, but thought I would ask to be safe as it is such an investment to get a bike and couldn’t find a good comparable for a road bike!
I am 177cm tall and have an 80.5cm inseam (both barefoot). From fingertip to fingertip (ape index) I am just under 173cm.
I am going for a Specialized Allez E5 Elite 2020 Road Bike. I think I am exactly between a 54″ frame and 56″ frame and am really struggling to pick the best option. I am pretty comfortable on road bikes and recall sizing being an issue last time around, however, I can’t for the life of me remember what size frame I purchased last and it has been some years since I last rode due to an accident.
Many thanks in advance!!
https://www.evanscycles.com/specialized-allez-e5-elite-2020-road-bike-EV366597
Hi Ally, I think a 54cm would work well for you considering your arm span is quite a bit shorter than your height. Whichever size you end up choosing, you can make it work with small adjustments if you’re not 100% satisfied with the fit. 🙂
Hi Jeff,
I recently got a road bike that hurts my backside when I ride for more than about 5 minutes.
I’ve been told that it may be a number of things, that the bike may be too big for me or that it’s because I haven’t ridden properly in over a decade.
Any idea what it could be? I understand there are adjustments and accessories to help but surely they should only be needed to get you from one hour of comfort to two and not to help 5 mins?
Do I just need to push on through?
Thanks
Hey Danny, as you’ve been told, it could be a number of things, so it’s very hard for me to give you advice without knowing more details. Some of the most probable reasons are wrong bike size, poor fit, or poor flexibility.
If possible, I’d advise visiting a local bike shop or a bike fitter and checking whether or not the bike fits you. Improving your flexibility and mobility won’t hurt either. Definitely don’t push through it, though, pain is always our body’s way of telling us something important.
Good luck!
Hi! I’ve recently thought about buying a bike for fun and for exercise as well and was thinking a hybrid would be best for my purpose. I’m not looking to spend more than maybe $300-$400 at the most and I’ve read some of your articles on the best bikes in each category. I’m nervous to order online because of sizing and I’ve been looking on Craigslist and Facebook Marketplace as well. Depending on the bike, it looks like I’m always right on the cusp of two sizes and I’m not sure which way to err. I’m a woman who is 5 feet 5 inches tall and my inseam is 30 inches. Can I use just these two measurements and get a good fit? Thank you for any help!!!
Hi Angie, your inseam length is pretty much average for your height, so I don’t think you’d make a mistake going either way. If I had to choose, I’d recommend going for the smaller size when in doubt as it is easier to get the right fit.
First of all big thank you for the guidance!!! Here is my puzzle: Due to covid situation I have to order bike online – my height 176.5 cm (about 5’9.5), inseam about 53-54cm. Based on several methods listed for hybrid bike good fit for me is 17″. Manufacturer says that most 5’9 to 5’11 fit 20 inch bike. Exact bike geometry is available in the link below. Other options are 15 inch bike or 17.5 inch. 15 inch bike is too small, 17.5 inch may be a little too big, but manufacturer says get 20 inch…
What do you think?
http://www.bikesdirect.com/products/motobecane/flat-bar-road-bikes/strada-express-24-commuter-flatbar-road.htm#top
Hi Mickay, I’d go with the manufacturer’s recommendation. Not all bikes are made the same, so it’s good to take their recommendations as a starting point.
Hi,
I have terrible lower back ache. Please inform the correct geometry for road bike. I am looking at some motobecane’s from BD, this would be my first bike after long time.
leg inseam – 83 cms (with shoes)
full arm length – 63 cms
height – 172 cms (without shoes)
28 y old male, avg body, sitting IT job
Thank you
I saw this bike on a deal other site for 56 Cms – 5’10” recommended and wondered if that would have fit me well. Website says I need 54 Cms with height of my 5’8.5” (without shoes)
http://www.bikesdirect.com/products/motobecane/super_strada_xiv.htm
Yes, it should fit you well. If necessary, you can put a shorter stem to shorten the reach of the bike.
Hi Rahul, I’d go with a 52cm size frame. Even 54cm could fit you well depending on the manufacturer. Make sure to get a bike with a more comfortable endurance geometry which would relieve some strain from your back. Good luck.
Hi there, great article.
I am 6′-0″ with a 32″ inseam. I was a mountain biker for long time and stopped for a few years after some injuries and surgeries.
I want to get back into riding and am looking at a gravel/cyclocross bike to transition to riding more road while still being able to use the fire roads and some trails to link up rides. I plan on doing long rides with a mix of about 60/40 paved/unpaved.
I just bought a 56 cm Santa Cruz Stigmata (700c wheels) yesterday but was wondering if there is any worth to changing the frame size to a 58 cm as I do have the option within 30 days to make that request. The bike position is going to take some getting used to coming from a mountain biking background but I know that will just take time and some miles.
I only had on my street shoes but when I stood over the top bar it was very close and almost touching my crotch area so I felt that the 56 cm was correct at the time as I wouldn’t want the top tube any higher. I also checked the pedal position with the center of pedal at the ball of my foot and while its close don’t believe I will get any toe overlap.
I get a bit OCD and would like to ask what you thought.
You have nothing to be worried about, you made a good decision. The standover height on the 58cm model is almost an inch higher, which would likely be too high for you. Ride as much as you can in the following days and then make the final decision, though. 🙂
Hey Jeff,
I am 189 cm and i weigh around 80 kg. I am not sure wether to choose 58, 59 or 60 for frame size for my road bike. Thanks i advance!
Hi Martynas, it depends on your inseam length and your torso length, as well as on bike’s geometry. All three sizes could be a good fit. However, I’d say 60cm is the most common choice for your height.
Hey Jeff,
So I’m in that weird height bracket- 6ft tall- and I’m wondering about the kind of bike size I should be going for.
My inseam is about 87cm and I’m currently looking for a road bike (preferably with a vintage frame- if that makes a difference manufacturing wise). I’d eventually like to get a touring bike too.
It would be really helpful if you could please help me with both of these kinds of sizes. Thank you in advance! 🙂
Hey Eliseo, I think you can’t go wrong with a 58cm frame for both road and touring models. In case the touring bike you’re interested in is measured in inches, I’d go for a 20″ size frame. 🙂
Hi, I am looking at a bike a co-worker is selling. It is a 26 ” mountain bike. I am 5’6″ . The bike is a 15 ” frame. Do you think this bike will be too small?
Yes, Tina, that bike will be too small for you. You need a bigger size frame. 🙂
Hi Jeff,
I use to bike all the time when I was younger. I haven’t been on a bike in a while and looking to slowly ease back in. I am 5 ‘ and with the 26″ i do not feel comfortable when my feet don’t touch the ground. I am searching for a 24″ model – is this a good idea?
Hi Mimi, modern bikes are made in such a way that you cannot touch the ground with your feet while you’re sitting on the saddle. If you want to be able to do that, you should get a cruiser, such as Electra Townie. I don’t recommend buying a 24″ bike at your height.
Hi Jeff,
Great comments and feedback!
I am looking for a Mountain bike and have been quite confused with the options.
I am 5.9′ in height and weigh 210 lbs. I discovered a bike that i thought i liked and went ahead and bought it – Genesis v2100 men’s mountain bike. This one is 26″. I believe the inseam /frame is slightly over 18″….unless i am measuring it wrong. I am now having second thoughts and wondering if i should get 27.5″ version Or some other bike. Will appreciate any suggestions or thoughts.
Hey Mike, thank you! If you enjoy that bike and it doesn’t give you any pains and aches, there’s no need to change it. Personally, I am a much bigger fan of bigger wheels, so I think 27.5″ would give you more options in terms of where and how you can ride your bike. A 29″ bike could fit you nicely as well, if you plan on hitting some more serious trails. 🙂
Hi Jeff,
I’m looking to purchase a bike for my nephew He is 11 years old; 63 inches and has about a 27 inch inseam. He is a relatively new rider but I would ,Ike a bike that he can continue to grow into. I’m thinking a step through bike would be best for him. What are you suggestions on size, bike style and brand? Thank you so much for your help!
Beth
Hi Beth, you could get a bike with 26″ or 27.5″ wheels and a 15″ frame. Co-op Cycles 1.0 is a decent choice, but you can also look into Trek bikes, they have some pretty good models with small sizes. Check out Trek’s Marlin series. 🙂
hi! My 14 year old daughter is in need of a new bike. We were going to get her a standard mountain bike to use around our neighborhood for her birthday in a few weeks. She is about 5 feet 6 / 5 feet 7 with very long legs.
1. What size should we get her? With covid, stores are closed and we’re unable to try anything.
2. Is there a brand that you would recommend that is reliable but not overly expensive? She is hard on her stuff.
3. Should we get her a women’s bike or a gender neutral one? is there a difference?
Thank you!
Hey Marie, at the moment, Trek Marlin series and Cannondale Quick or Quick CX series are very popular and have proven to be durable and reliable. I don’t think you need to be hunting for a women’s bike, a unisex model will do as well. The only difference is usually the saddle, which you can easily change if it proves to be uncomfortable.
As for the size, I’d recommend Medium or Large, depending on the model you choose. 🙂
Jeff,
Thanks for the insights on bike sizing. I seem to be right in between sizes with road/gravel bikes. I am right at 6′ 2″ and a 1/2 and I have a 34 inch inseem. Not sure if I am an Xl/L or if I should go for a 58 cm or 60 cm bike. Each brand seems just a bit different in terms of sizing. Thank you.
Hey Jack, there’s no easy answer. I think 58cm is a good fit, but as you pointed out, it depends on the brand as well. 🙂
Hi Jeff,
I read through your article and the comments with great interest as I’m about to buy my first bike. I want to make sure that I’m going to order the right size because it will be from abroad so I can’t make a mistake.
I’m female, 173 cm (about 5’8”) height and 82 cm (about 32”) legs. It will be my 42 birthday soon and this will be my present. 🙂 As I have never owned one before I’m more worried about my choice. I need a bike mainly for cycling on roads and some local cycle routes (dirt/gravel tracks). This is a bike I like (sadly it’s quite limited choice now due pandemic to order even online)
https://www.bikester.co.uk/ortler-degoya-city-bike-black-885927.html
So I’m confused if I need 50 or 55 cm frame?
Thank you in advance,
Anastasia
Hi Anastasia, you can go for the 50cm frame in this case because the geometry of this bike is different from ordinary hybrid and MTBs that our charts are intended for. It should fit you pretty well. Have fun and happy birthday! 🙂
Hi Jeff! Thank you for your comments. Well, I have an issue with ordering online bike. I bought L (19″) according to recommendation of the manufacture https://qayron.com/kola/trail–c6/carma-140-q-29–p12 that states 180-190cm (im 188,5)
I have a feeling that bike is bit small to my size (6.185 feet) or I do not feel confident with chosen diameter. I do trails, jumps and tricks , sometimes ride technical AM.. Changing bike is kinda a big deal (post, packing etc.).. Do you think my size of the bike is wrong?
thank you, kinda nervous now
After testing today, it seems like during clibing and flat road I have feeling like 20″ would be better, but during downhill, trails and manuals its kinda… emmh.. not really. Jeff, what do you think? Is this bike small for me? My internal is around 95
The reach does seem a bit short, but then again, if your inseam is 95cm at that height, it means your torso is quite short, so it should fit you well. I think one ride is not enough to make such a big decision. Why not ride it a few more times and see how it feels after you get used a bit?
I have a 13 yo daughter who had her bike stolen before she ever got to ride it when she was younger and she was so upset she refused to learn for years. She now wants a bike and wants to learn what size and type of bike would you recommend for her? She is 5’2 3/4″ tall and has a longer torso. Thanks for all your help!
Hi Dee, it’s nice to hear your daughter wants to give cycling a second chance. 🙂 I recommend getting a MTB for your daughter, it will help her be more confident because of wider tires and low standover height on most models. As for the size, a 15″ frame would be a good choice.
Hi,
I am 6 foot 7 and I am looking to purchase a road bike needed for working as a messenger in a crowded city, so I don’t mind if the bike is a little smaller maybe than what would be advised for my height. What frame size do you think I should look for.
Thank you in advance
Hi Kelly, if you don’t mind the bike being a tad too small, then you can go for a 63cm size frame. It fits riders up to 6’6″ usually.
Thank you for the information you posted. However, I am a bit confused and need some help.
I am an experienced–yet amateur–mountain biker, and my last two bikes were bought without much effort put into sizing them (epic fail). I am looking to transition to a hybrid trail/road bike. I am 6’3″ and my inseam of 37″/94cm is off of your charts. I only see in your charts a 22″ bike being the largest, yet you mention a 29″ bike? Are some bike sizes by the frame size and others by the wheel size? I have always been confused by this.
Thank you for your help!
Hey Eric, the 29″ refers to the wheel size. Your inseam is quite a bit longer than average for your height, so I’d recommend fitting the bike according to your height/upper body. I think a 22″ hybrid bike would be a good fit for you. But, given your unusual proportions and bad experience, it’s best to try a few bikes to see how they feel.
Hi Jeff, hope you’re doing well. If you’re still giving size advice, I’m 6’1 to 6’2 and looking for a mountain bike, no specific brand. What size would you recommend I go for? Thanks
Hey Sam, you should be happy with a 21″ mountain bike. Have fun!
Hi Jeff! So cool that you are replying to all these comments – thank you! I’m 186cm / 34 inch leg inseam and am looking at a 22inch road bike – is that too small??
Thank you!!
Eva
Hi Eva, road bike sizes are generally expressed using centimeters, not inches. If 22″ in this case corresponds to a 55cm road bike, I’d say that’s too small for you. You should get a 58cm size frame.
Hi Jeff,
I’m looking for a road bike for my sister now. She’s between 5’3” and 5’4”. What frame size should I be looking for her? Thanks
Hi San, I recommend a 51cm or 52cm size frame.
Does weight matter when looking for a bike? I am also between 5’3″ – 5’4″ and looking for a new bike
It doesn’t matter too much in regards to the fit. However, most road bikes have a 250 lbs. weight limit and most mountain bikes cap at 300 lbs. So that’s something to consider if you are struggling with weight.
I’m confused I’m 5’9 1/2 with a 29 1/2 inseam looking for a rode bike
Hey Hank, 58cm should be ideal for you. 🙂
Hi I wonder if you could help me, as im new to this, im looking to buy a womens hybrid bike, I am 5’5, and inside leg of 29 inches, do I need a 16,17 or 18 inch frame
Hi Deborah, I believe a 16″ size frame would be a good fit for you. Perhaps even 15″ for some models. But definitely not 17″ or 18″.
I am 6 foot tall and have small legs. my inseam is around 30″ . I am confused at what size bike I need. I have a bike now that is WAY too big for me.
Hi Elliott, I recommend a 58/60cm road bike size or a 20″ mountain bike size. If your legs are short, it means your torso is longer, so you should need a bike with slightly longer reach so as not to feel too cramped.
Hi Jeff,
So kind of you to give all this advice! I am looking to buy a hybrid electric bike as I have a connective tissue disorder that sometimes flares up and would make it hard to always ride a normal bike. I am a 5’1 woman with an inseam of 28”. I find that overstretching can cause a flare up. I have found an ebike with 14.5” frame but it has 24” wheels. Do you think these wheels would prove very small for unassisted cycling as I want to not use the electrics when I am able? Thanks so much.
Hi Karen, there’s no simple answer. I’d say it can be good as it might put your body in a more upright position and prevent flare-ups. Though, I believe 26″ wheels would be a better choice.
Thank you for all the information and particularly for answering all of these comments! This is so helpful particularly when it is difficult to go visit any bike stores in town. I wanted to ask you, if you would have any specific model/brand recommendations for me. I am looking for an adventure/cyclocross/gravel/touring kind of bike, that is more robust and stable than a cross bike but fitting for longer daily trips, but my problem is that I am not used to men’s model and would most likely find it too uncomfortable not being able to reach the ground relatively easily (still without compromising good cycling position of course). I believe a saddle position of course matters, but would it in this case also make sense to look for a slightly smaller size of a bike than otherwise recommended for my height? Or just narrow the search down to the women’s models that are sadly rather rare it seems? I am 172 cm tall. Thank you so much for your time and I wish everything’s good with you and your family during these times!
Hi Hanna, I’m glad my answers can help! 🙂
I don’t recommend choosing a smaller size because you might feel too cramped on it. Plus, it might force you to put a longer stem which will stretch you out over the bike.
Not sure what your budget is, but have you considered Co-op Cycles? For example, ADV 3.1 or ADV 4.2? They have pretty low standover clearance and fit all of the other requirements you have. We wrote about it here, if you want to check it out.
Hi Jeff,
I am 194cm. I also have a longer upper body and longer reach. What frames size do I need to use in mountain bike and road bike? What tyre size would be the best for me?
I have looked at the GMC Denali road/gravel bike with frame size of 22.5 inches and 700c wheels but unsure if this is a good fit (size wise).
Thanks,
Michael
Hey Michael, I recommend a 62cm road bike and a 22″/23″ mtb. I think that Denali might be too small for you. On their site it says: Fits riders 5’8″ to 6’2″
Hi Jeff
My height is 5 feet 7 inch (170 cm). I bought a bike specialized Sirrus which is large(L) size. After reading the blog it look like I could have bought medium size. Unfortunately I can’t exchange it since I have used . Please suggest me what modifications I can do it to make perfect.
Hi Rama, you’re right, you would have been better off with a Medium. If there are spacers above your stem, you can move them under the stem to lift it up and shorten the reach. If that’s not possible, you can also replace the stem with a 1-2cm shorter one.
Bring the saddle a bit forward as well (1cm) but don’t over-do it, as it might mess up other elements of the fit. Of course, if you can afford it, a professional bike fit would be the best choice at this point.
If you don’t ride too much and you feel ok on the bike, then you shouldn’t be too concerned about the size.
Hi Jeff
Looking at the cervelo c3 I am 5’7″ tall with a 31 inside leg. I fall between a 51 and 54 in the frame size category. What would you recomend. Obviously it’s an online sale due to lockdown. Any help would be appreciated.
Hi Michael, I recommend choosing the 54cm size frame. Enjoy your new bike!
Hi Jeff,
What is your road bike recommendation for a 5’8″ (173cm) female with a 32″ (82cm) inseam?
My height puts me in the S-M section, while my inseam puts me in the L-XL section. Thanks much! (love the infographic too)
Hi Michele, I recommend a 55cm road bike or a 17″-18″ mountain bike, which is usually referred to as Medium. 🙂
I’m getting very different results.
Based on method 1 (height = 169cm) I should get a 16″ bike.
Based on method 2 (inseam = 74cm) I should get a 19″ bike.
Based on Method 3, I should get a 16/17″ bike.
Based on Method 4, I should get a 15/16″ bike.
What am I to go for?
Hi Simon, I could have helped you more if you told me your height and inseam length as well. 🙂
Hi Jeff,
Am I right in assuming I should go for a size somewhere between my road and MTB sizing for a gravel bike?
I’m experience at both road racing and DH MTB.
Hey Mike, gravel bikes have very similar geometry to endurance road bikes. I would just follow the manufacturer’s recommendations, the same as with road bikes.
Hi Jeff
Thank you ever so much for replying to everyone it’s quite remarkable what you’re doing – well done. I have a dilemma my girlfriend is 5″1 with an inseam of 72 and she would like a Trek Merlin 7. However, the bike is only available is extra small 13.5 frame number. Would this size be ok? Unfortunately small are all sold out, there are a few medium but I think they’ll be too big.
I’m also in a quandry myself. I’m 6″1 inseam 87 and the bikes I’m looking at have a reach of 435mm in size Large and 450mm in extra large, however I’m concerned the extra large will be too big despite the longer better reach, Do you think 435mm reach is too small? I’m looking at some trail, cross country and general riding. The head angle is 70.5 degrees and the seat angle is 73,5 on the large. I also have another bike I’m looking at which is only in size medium but the reach is around 450mm, standover is 819mm, seat angle 74.5 degrees and head angle 66.5 degrees – would that be too small?
Thank you for the incredible support.
Hi Keith, you’re welcome, I’m glad my answers provide some help with this confusing topic.
As far as standover height is concerned, the XS size frame is a much better fit for your girlfriend. She’s at the upper limit of the recommended height for XS, but I don’t think that should be a problem — she’s still within the recommended range. So if XS is the only option, I would go for it.
I think you have slightly longer legs than average, meaning your torso must be shorter. Therefore, I don’t think that a 435mm reach would be too small, even though 450mm would seem better for you in isolation. The other bike you mention seems a bit more slack and stretched out, but just considering the reach I’d say it should fit you well.
That’s as much as I can help without knowing the actual models.
hi Jeff
i’m planning to buy Giant fathom 2, 2020
I am 6 foot (183 cm) ,and i find out i must buy Large size, it comes in both 29er and 27.5 wheels.
on both bikes, all components are the same except 27.5 inch one comes with dropper post.
i would like to get the one with dropper post, but should i consider my height and get the 29er? or 27.5 is fine too for my height? i’ll be happy to get your advice.
https://www.giant-bicycles.com/us/fathom-2
https://www.giant-bicycles.com/us/fathom-29-2
thank you so much, Narek
Hi Narek, the version with 27.5″ wheels is perfectly fine for you. You should choose the wheels depending on what you want to achieve with your bike and what type of handling and riding you wish to get out of it. The experience of riding 27.5″ and 29″ wheels is pretty different. Hope this helps. 🙂
Hi Jeff,
I am thinking of riding a bike again after three decades of not (too many dog walks). I am thinking of getting a BikesDirect.com 2020 Motobecane Elite Eight DISC with Genuine Shimano Hydraulic Disc Brakes +LockOut Forks that is not a budget breaker. It is a hybrid bike with 700×42 cm tires that has off-road capabilities. I am somewhere between 175.3-176.5 cm in height and have an inseam of 78.7 cm. The BikesDirect sizing guide for this particular bike recommends that I should go with a 17.5 inch frame. Should I order this bike with this frame size or should I go for the 19 inch frame?
Hi Mitchell, I think it’s best to follow their guidelines and go for the 17.5″ size frame. They made those recommendations based on the geometry of the bike.
Anyways, it’s great that you chose to go back to cycling after such a long hiatus. I hope you fall in love with it all over again!
Hi i planing to buy cannondale trail 7 online. What size should i order? My height is 175cm .
Should i get M 27.5?
Hi Sameer, yes, that’s a good size for you. Have fun!
Hi Jeff
My wife and I are looking to get some bikes for us. Mainly would be riding on a gravel trails. Problem i am a large guy 6’3″ 315lbs.. is there a bike out there for me?? Want to start losing weight.. used to bmx race when I was a kid lol…my wife is 5’3″ what size for her.
Hi Mike, most MTBs have a 300 lbs weight limit. I think a hardtail MTB, such as one of the Trek Marlin models would be a good choice for those gravel roads if you dropped 15-20 lbs before purchasing. 🙂
As far as sizes go, you could go for a 21″ size frame and your wife should choose a 15″ frame. Enjoy!
Hi Jeff!
I scrolled through quite a few comments but am still a little confused.I am 5 ft tall with a 27 inch inseam, and assumed i would need a children’s bike or an XS. Im looking at a Raleigh Cadent 1 ST, but i only see a size small, which it seems to suggest is for a height of 5’4″ to 5’7″. The geometry info on Raleigh’s website doesn’t seem to line up with measurements i’m seeing here. I cant find the frame size or the tire size so i’m worried it will be too big. The standover height is the only relevant measurement i can find, and it seems to be around 24 inches which i think is plenty of room?
Hi Erin, standover height on that bike will not be a problem since it’s a step-through frame. When it comes to frame sizing, there are very few standards in the industry, which is why things easily become confusing. I think this bike could work for you, even though it might be slightly bigger than ideal. If you don’t plan to ride very long distances, it should fit you decently well.
Hi Jeff!
Thank you for your article. I’m 5’4” and just recently purchased a bike. It was marketed as women’s, but unfortunately I believe it may have actually been a child’s bike. The wheels are 24 inches. Will this be a negative impact on my ride? It’s a mountain bike. Thank you!
Hi Krista, you’re right. Bikes with 24″ wheels are considered to be kids’ bikes or bikes for adults who are up to 5’0″ in height. A bike with 27.5″ wheels would be a much better choice for you.
Hello!
I am looking at a comfort hybrid, I am 5.5 1/2 ft tall and have a inseam of 30 inches, I recently purchased a18” but wondering if that is too big, if the frame is too big? Otherwise when on it, my leg extended down in pedal is perfect!
Can you please share what you think?
Hi Sammie, if you only listened to the charts, a 16″ size frame would be a better choice. However, if you listen to your body and it tells you it likes the bike, then keep riding it. 🙂
Hi Jeff, thank you for taking your time to answer all these comments.
I am quite tall and most charts don’t cover my height. I am 201 cm (6 foot 7 inches) tall and leg length of about 96 cm (37 inches). What do you think is an appropriate bike size for me? My local store recommends 24 inches but I think this is just because they don’t have anything larger than that.
You’re welcome, Magnus! Your LBS is right, you need a 24″ or a 25″ bike (if you can find one). 24″ is considered to be for riders up to 6’6″ tall, but it will probably work for you as well with or without some minor changes.
Thank you for this.
My 9 year old rode a a short adult neighbor’s road bike (size s) and did great on it, but he is 53″ with a 24.5″ inseam. We want to get him a Sirrus 2.0 from Specialized and I am trying to decide between the XXS vs the XS. I would like him to get one that fits well, but also that he will not outgrow in a year. What do you recommend?
I am also considering an XS Trek Verve 2 Lowstep as I think having the lower bar will make it easier to mount and dismount.
Hi YT, if you get him the Sirrus 2.0, I recommend going for the XXS frame. Trek Verve 2 Lowstep will make it easier for him to mount and dismount and will give him more room to grow, but it might be a bit too big in the beginning. It all depends on how fast and how much he is going to grow.
Hi,
Would you recommend this bike for a woman that is 5’3″?
https://www.canadiantire.ca/en/pdp/supercycle-surge-dual-suspension-mountain-bike-26-in-0711926p.html?rrec=true#spc
Hi Zakk, the information on the website regarding sizing and geometry is very obscure, so I can’t give you a definitive answer. However, considering it’s a bike with 26″ wheels, it could work. It’s best to try it out.
Hi,
I am 173cm height with short legs (75cm inseam).
For a road bike, from my height you recommend 54cm or size M. But for my inseam, I see it should be 50cm. In that case, what frame size to choose ? (for a road bike)?
Also, is it mandatory to have Standover length on the bike equivalent or higher than inseam?
Thank you
Alan
Hi Alan, the fact you have slightly shorter legs than average means your torso is longer, so I’d recommend a 54cm frame, just like the charts suggest. Standover height is pretty important to consider — if it’s higher than your inseam length, you’ll bang your delicate region on the top tube every time you dismount. 🙂
I haven’t ridden in years and am looking at a purchasing a hybrid bike. However, looking at their sizing guide, I fall right between sizes & not sure if I should size up or down (15” or 17” frame). I’m about 167 cm tall with a 75 cm inseam. Thanks for any help you can offer!
Hi Stacey, check the geometry chart and compare your inseam to that bike’s standover clearance. If your inseam is longer than the 17″ frame’s standover clearance, I’d go with that one. If it’s shorter, choose the 15″ frame. Good luck!
Hi Jeff – Great website with really insightful advice!
I’m looking to buy a Specialized Sirrus 3.0 Hybrid bike but can’t figure out what size I should order. I’m between 5’9 and 5’10 (slightly heavy build) with an inseam of 30 inches. It seems that I’m on the cusp between Medium and Large as far as I can tell. In your experience which is the best to take the plunge with? Clearly I want to avoid sending it back to the retailer if at all possible. Any thoughts?
Hi Noah, both could work, but since you mention having a slightly heavy build, I’d recommend the Large size frame. If you’re over 5’9″, you’re already out of the Medium range. Hope this helps!
Hi Jeff,
I would like to purchase a bike. I am a 5’4″ woman. I’m looking at a 27.5″ wheel and 15″ frame. Is that an appropriate size for me? Or should I go up to the 17″ frame? Thank you so much for you input!
Hi Darla, a 15″ or a 16″ bike would be a good fit for you. I believe a 17″ size frame would be too big. Enjoy!
Hi thanks for this article, like everyone messaging you I’m trying to work out which frame size and wheel size having not ridden for years. I want a classic style city bike
I’m a lady and nearly 5’7.5” tall with an inner leg measurement of 31.5”
or in cm height is 172cm and inner leg is 80cm
I thought I had worked out by the multiply by 0.685 the answer was 54.8cm which is a 21.5 “ frame? But I saw you recommend another woman of a vaguely similar height to get an 18” frame?
Am very confused and could do with some expert help! I really don’t want a bike that feels like a kids bike!
Thanks
Hi Tess, mountain bikes are sized in inches and road/city/hybrid bikes are usually sized in centimeters. These cannot be compared because the geometry of the said bikes is different. So a 54 cm road bike is not the same as a 21.5″ mountain bike, the latter one is much bigger.
In your case, I’d recommend you go with a 17″ frame considering your inseam is slightly longer than the average for your height, meaning your torso is shorter than the average. The equivalent in cm would be 54cm. Hope this helps!
I want to get a bike for my 14-year-old daughter. She is new to bike riding and will mostly use it on paved paths with some hills. She is 5’3” and has an inseam of 27 inches. Can you recommend a bike size for her and maybe a type of bike we should be looking at? I would like it to be a bike that she could still use for the next couple of years even though she is still growing. I appreciate your help!
Hi Kathy, a hybrid bike with 700c wheels or a mountain bike with 27.5″ wheels (with or without front suspension) are solid choices for all-around casual riding. As far as sizes go, I’d recommend a 16″/50cm frame.
Hi Jeff,
I am in between 6’0 and 6’1″, with a 34″ inseam, What size (cm) bike would work best.
I am a casual rider, looking to buy my first bike. I found a 61 cm bike for sale. Is that too big?
Hey Travis, a 58cm bike would be a better fit for you. A 61cm bike could work, but you’d most certainly have to make some changes to shorten the reach, plus the standover height could be a problem as well depending on the model you’re considering.
Hi Jeff
I am looking at purchasing a 2018 or 2019 Quintana Roo PRsix online and am trying to figure out my correct size. I am 5’7″ tall and have a 29.5″ inseam. it seems like I might be in-between sizes according your guides as well as the QR websites (50 or 52). I was leaning toward the 50 but I am hoping you can help narrow down what size could fit me better. Thank you for this amazing reference guide as well as your help.
Jeff
Hey Jeff, fitting a TT bike online is pretty tricky since getting the right fit is very important. I recommend measuring your torso length and contacting the Quintana Roo customer support team. They can help you out when you’re in-between two sizes, as far as I can see. Your inseam length seems to be average for your height, so it’s difficult to decide between 52 and 54 based on that. Sorry I could not help more and good luck!
Hello,
I am 4’10 with a 24 inch inseam. My husband bought me a women’s hybrid bike with a 15 inch frame and it was too big. I’m thinking I might need a youth bike but I need to be sure what size to get. Please help!
Hey Kayla, you could get a kids bike with 24″ wheels, that would definitely work. However, adult bikes also come in 14″ (XXS) sizes, so you can look into those options as well. What size wheels does your bike have? If they are 700c, you would certainly be better off with 26″ wheels. That could solve your problem. Good luck!
Hi there –
Fitting a bike for my daughter, she’s 5′ tall with an inseam of 28″. Can you recommend a good size bike for her? She’s 10 years old, so will be growing.
Thanks for any advice!
Hi Chris, a 15″ size frame would be a good fit for her and give her room to grow up to 5’5″.
Hi Jeff
I am 177cm with an inseam 80cm. I am wondering whether a 17(M) or 19(L) inch GT 29er full suspension mountain bike will fit me better?
I have been always riding a conservative M size 17inch hardtail and the seatpost has to raise a bit higher. As the next size of GT bike is from 17 to 19inch, will need your advise.
Hi Sam, the 19″ size could definitely work four you, but I personally think a 17″ size frame is a better fit for your height. However, if you feel cramped and you think you’d be better off on a bigger frame, go for it.
Hi Jay,
Its walter again, follow up question, well i was thinking of getting the chameleon 27.5 small aluminum D+ spec which had a standover height of 27.01
I measured again (embarassingly) and tip of my sack when let lose is at 27(inseam) i was thinking i can wear quarter inch shoes and i can get away with it.
What are your Thoughts? My other option was getting the sc tallboy in xs but i didnt really need a full suspension. Do you have augfestion on a decent hardtail for my height?
Well, if that’s the case, I think you’ll be able to get away with it with shoes on. 🙂
Hi Jeff,
Thank you for this article. With all the social distancing cant really go to a bike shop to check.
I am 5’2 with a 26.5 inseam. I am eyeing a santa cruz chameleon but on the fence if it will be too high for me or itvwill hit my balls when standong over
Hey Walter, the smallest size (S) shows a standover clearance of 27.28″ (27.5″ wheels) and 27.36″ (29″ wheels). So I’d say your nether region would be in danger. 🙂
Hi Jeff,
My height is 157cm and I am looking for a bicycle to ride around my townhouse, not actually on a road.
I am 63 years old, since know I used to ride my kids bikes.
I would like to know what kind of bike and what size should I look for.
I appreciate your advice.
Thanks,
Sarah
Hi Sarah, if you are in good physical health, a mountain bike with or without front suspension would be a good choice. Otherwise, I’d recommend a hybrid with a step-through frame that would allow you to get on and off the bike with more ease. As for the size, a 15″ frame should be the way to go.
Hi Jeff, the amount of feedback you’ve given the readers here is incredible! My wife and I are looking for our first adult bikes for riding around our lake, mostly roads and paved trails with the kids. Thinking mountain bikes, is that ideal?
I am 6’1” and 33in inseam. She is 5’10” and 34in inseam. 19inch frame for both? 27.5 or 29 wheels?
Thanks in advance!!!
Hi Ryan, I’m happy to help whenever I can!
I think a mountain bike would be a good choice if you don’t plan to ride too many miles. If you want to have long days and perhaps do some cycling workouts, trekking/hybrid would be a better choice.
If you go with mountain bikes, 19″ for both of you would be good. Though an 18″ frame would still be a better choice for your wife, I believe.
Have fun!
Hi Jeff
I am 5.5 female with 32″ inseam…should I go with 52cm or 54cm….so torn? Trying to order online during isolation. 🙂 Trek Domane SL 7
Thanks for your help!
Hi Janet, I think a 52cm size frame would be a better choice for you. You have longer legs than average for your height, so I think the smaller option with shorter reach would be better for your shorter torso.
Hi Jeff! I’m looking to purchase a road bike. I’m 5’6 with a 32/33in inside leg. My legs are long but my upper body is pretty short so a lot of times I have problems with the reach being too far. What size bike would you recommend?
Hey Becca, I think a 51-52cm size frame would be a good starting point. If your reach is too long, you can always put a few spacers under the stem and raise it (if there is room), as well as put a slightly shorter stem.
Road bike geometries also differ from model to model. Get a road bike with endurance geometry which generally have shorter reach and longer stack. Hope this helps!
Hi Jeff,
I am wanting to purchase a new hybrid bike.
I am 5ft 2.5″ and inseam is 71cm.
I am unsure whether to go for a small 14“ or medium bike 16“ bike.
Thank you
Hey Hannah, a 15″ bike would be the best choice. But if only 14″ and 16″ are available, I’d go for the smaller 14″ frame.
Hello Im 5’1 heights male and also a small legs
and im looking for mountain bike or road bike. can i know what is the best size for me thanks for advise and answer and GODBLESS TO YOU
Hi Mark, a 15″ size bike would be a good option for you. Enjoy!
Hi Jeff, this is a great article and thank you for taking the time to explain sizing.. very helpful.
I am a beginner with road bikes and do about 30-40 mile rides through rolling hills in our area.
I am 188 cms and 182 lbs. 33 inseam.
I was so far using my friend’s 2011 Cannondale Synapse Carbon 105 (58 inch).
I purchased this weekend a Trek ALR5 60 Emonda for myself.
On my first ride yesterday, i struggled more than usual on the hills (felt i needed to put more effort and could have used another gear)
I am wondering now if
1. Its the geometry of the bike (and i should have gotten the Domane SL5 (endurance fit) instead. I believe Emonda is a H2 fit
2. I should have gotten the 58, though 1 bike store felt i am better in a 60 and another said 58 🙁
3. when i sit on the 60, i feel more comfortable (i think)
Just wondering if i made the right choice or too soon to tell ?
Thank you!
Hey Vish, can you compare the reach on both bikes? Is it perhaps shorter or longer on your new Emonda? That can have an impact on your performance, you might have to switch out the stem. Emonda has an H2 fit, but that’s an endurance fit, intended to suit the majority of riders out there.
Also, is gearing the same on your old and new bike? Perhaps you were really lacking a few extra gears on Emonda. 🙂
If you feel good on a 60cm frame, then you didn’t make a mistake. Though, I believe it is still too early to say. You need to do a few long rides to really tell the difference. But I recommend comparing the reach on those two bikes and seeing if you can dial it in, in case it is different.
Hi Jeff,
Great article, I’ve already sent it to a few friends! I’m 5’9″ and currently have a 17″ bike with 26″ wheels. Being that I’m on the cusp of TIRE size charts, leaving bike-frame size aside at the moment, can you enlighten me with the difference between 26″ and 29″ wheels besides the obvious? I’m primarily doing trail riding with a mountain bike, and I’m curious if the larger diameter wheels would require less force to go over “slightly bumpy” terrain. What about the difference in hill-climbing? I guess I should’ve paid more attention in Physics class! My wife doesn’t own a bike, but I’m currently trying to outfit her with one as she would like to join me on the trails. This is how I reached this wonderful post. She is 5’2″, and at the moment I don’t have her In-seam measurement. I imagine startling her at 5am this morning to measure it could be quite interesting!
Hi Liam! Thanks, I’m happy you find the article helpful!
The difference in feel and performance between 26″ and 29″ is huge. 26″ wheels are smaller and lighter, thus they will accelerate much more easily and give you better maneuverability when cornering and avoiding obstacles on the trails.
On the other hand, 29″ wheels are heavier, bulkier, and more difficult to “get going,” but once you pick up speed, they will roll over bumpy terrain with a lot more ease. They’re excellent for descending and speedy trail riding. 27.5″ wheels would be a good compromise that could do it all – ride around bends, climb, and descend.
A 15″ size bike with 27.5″ wheels would be a good option for your wife, I think. Whereas you could go with either 27.5″ or 29″ wheels and a 17″ frame, in my opinion.
Have fun!
Hello I’m a 5’3 male and I have seen a Gary fisher sugar 4 21” for sale would this be okay for me?
That’s too big, you need a 16″ size frame.
Trying to figure out sizing for a hybrid bike. I’m 6’0 tall with a 32” inseam. Would a 17” frame in a Fuji Sunfire be too small for me?
It depends. I believe an 18″ frame would be a better fit, but a 17″ size frame could work as well, it depends on your build.
Hi Jeff! I thought I should give a try and ask!
I’m 5″1 with short legs, I’m looking at a 24″ tire bike. Will that be okay for my size?
Hey Nina. At your height, you could easily ride a bike with 26″ or even 27.5″ wheels. What do you think about Co-op Cycles DRT 1.0? You can also check out some models with 24″ wheels from Co-op Cycles’ REV range.
Jeff:
I’m a 6’1″ 270lbs male with a 34 inch seam. What size and what road bike should I purchase.
Hi Jake. A 58cm size road bike would be a good fit for you. Considering your weight, I’d go for a touring bike or a gravel bike because of stronger wheels and bigger tires. Have fun!
Hi! Great article!
I’m a big guy…6’5, 34 in inseam, but I also weigh 255 lbs. I’ve been shopping around and some places list bikes by wheel size and others by frame size, and most bikes I’ve looked at only have a 250 lb weight limit. Being a taller, heavier guy, I’m having trouble figuring out which is best and I can’t tell if the wheel size or frame size have any type of relationship in general. I’m also debating between a road and a mountain bike, but it seems like the mountain bikes tend to be a bit more sturdy. Any advice?
Hey Seth, adult bikes are measured based on frame size, but wheel size is important as well for other reasons. At 6’5″, a 62cm road bike would be a good fit for you. You could get a touring or a gravel model because they have stronger wheels and frames and are built to withstand more.
Most mountain bikes have a 300 lbs. weight limit, so finding one that can support your weight should not be a big problem. Trek Marlin series is a good example. They also have XL and 2XL size frames.
Hi,
I’m looking for a 3 wheeled bike for my 69 year old mom. She’s 5′ feet tall and is a little chunky. I am uncertain of the correct size frame to order online. I would like to get her one with the low step over frame. Looking for any recommendations.
Thank you in advance
Best regards,
Glenn N
Hey Glenn, check out Sixthreezero Tricycles. There are some cheap models and they meet your requirements.
Hi Jeff,
This is a great article and very helpful since all of the stores are still closed in my area. I am looking to get into biking. I would like to purchase a mountain bike but I’m requesting some help from you since my shopping is limited to online. I am 5’8 165 lb my inseam is 181 cm. Would a 26″ tire or 24″ tire size be better for a mountain bike? Sometimes it’s hard to find frame size? Any recommendation would help. Thank you in advance.
Hey Chrissy, if you are 5’8″ tall, I recommend a bike with 27.5″ or 29″ wheels. The frame size should be around 17″-18″.
Hi Jeff,
Firstly, how amazing that you have replied and offered helpful personal advice to so many people in these comments! When I saw that I thought I might be able to ask for some advice too. Really great.
Looking to buy my first Gravel bike. I understand they have more in common with road bike geometry in all the sizing tables and not hybrids or mountain bikes. I am 6ft with inseam of 90cm. I have an XL mountain bike that fits me perfectly. The options on the gravel bike I like are 54cm frame or 58cm. Which do you think is a better option?
Thank you so much for any help you can give and for all the great advice you have been giving everyone here.
Hey Josh! Thanks for the kind words, I’m trying to help as much as I can.
Yes, you are right, gravel bikes have very similar geometry to endurance road bikes. I think a 58cm size frame would be a really good fit for you. A 54cm frame would definitely be too small. Have fun riding gravel!
Amazing, thank you!
Really good to hear I am thinking along the right tracks.
Hi
Looking to buy a hybrid bike i’m 6ft with a leg inseam of 32 what would be my perfect size?
Thanks
Hey Steve, a 17″ or an 18″ frame would be a good fit for you.
Hi dear Jeff,
I am looking for a bike for my mom for mother’s day. She is going to use her bike around our town hous in our compartments. I wonder if I have to order a round or mountain bike.
Her height is 170 cm.
What size of bike should I order for her.
I appreciate your time.
Hi Tayebe, a city bike or a hybrid would be a good choice. If your mom is an elderly woman, consider choosing a step-through frame, she’ll be able to get on and off more easily. As for the size, a 16″ frame would be a good choice. Hope your mom likes the gift!
Hi all m 5’10 looking to get into biking. Saw a good priced bike I’m looking to pick up tonight but of course with limited show rooms being open can’t shop around very much and not looking to throw alot of money right now until I build up the hobby
Shows 18″ frame. Would this be a good fit?
Schwinn GTX-2 Men’s Hybrid Bike, 700C
Hello Tommy, welcome to the world of cycling. 🙂 That 18″ frame would be a good fit for you. Have fun!
Hello!
I am trying to buy my first road bike but due to closures cannot visit a store. I am 5’3″ with a 25-26″ inseam. I’ve found several bikes at amazing prices on BikeIsland and BikesDirect (which I have read are legit stores but if you know otherwise please let me know). The affordable ones I’ve found are 47″ – will that be tall enough for me or should I go bigger?
Thank you so much for the helpful article!
Hey Sarah, BikeIsland and BikesDirect are legit stores as far as I know. As for the size, a 50cm frame would be a much better choice for you, in my opinion. I think a 47cm frame will be too small.
Hi Jeff,
I am looking to purchase a 2020 Motobecane
WhipShot CF RX600 gravel bike. I mostly mountain bike and have both a 29er and Fat bike. Both frames ate 18”. I am 5”5 with an inseam of 28. No concern with top tube height. I am more concerned with reach.
The Motobecane size charts seem off to me. I have bought two bikes from them in the past a 26er and Fatbike. I got the 18” frame instead of the suggested small for my height per their chart. Not sure if it is the same with gravel bikes. This is a different world for me, but per the calculations in your article above my frame size should be a 49. I am thinking of going with the Motobecane Frame that states it’s 49, but for a taller person.
Are my calculations correct? Should I get the 49 Medium?
Hey Jy, the geometry between gravel bikes and mountain/fat bike is different. They’re more similar to endurance road bikes. Looking at their charts, if you’re not worried about the standover height (as you state), I think their 49cm frame would work for you.
Hi Jeff. thanks for this article. unfortunately due to the isolation, i cant test out bikes. i am 36 and just want to learn to ride a bike on my own, watched some videos and they all say for learners, you should have a bike that your legs can stay flat on the ground easily. so i am not sure which size to buy. plus the sizes are not universal. i am 168cm tall and my inseam is 75cm. what would you recommend – i just need a bike for keep active. i saw this online- https://www.walmart.ca/en/ip/6000198834120 do you think this is a good size for me. i think its 26in
Hi Ade. It’s fantastic that you want to start cycling. 🙂 This bike has 700c wheels (larger than 26″), but there’s no information about frame size or geometry, so I can’t help you more. If you want to be able to touch the ground easily, I recommend a city bike or a cruiser. Though, if you get a 16″ mountain bike, you’ll be able to do that as well.
Hi Jeff,
What bikes do you recommend for heavy women (300 lbs.)? I am 5’4″ tall and have short legs.
Hey Monica, you can basically ride any mountain bike or fat bike. They are built to support 300 lbs. A 16″ mountain bike would suit you well. 🙂
Hi Jeff, I am 6.3 with a 34inch inside leg. I want to buy a Trek Domane SL 6 2020. The Trek website says I need a 60 frame. Sat on the Trek Emonda In the shop (Which is only a Trek dealer) which was a 58 frame. The chap said a 58 would suit me better. What is your view. Should I take use Trek website info or go with the chap. I don’t want to spend over £3k on a bike and it turning up too small or big.
Thanks
Matt
Hi Matt, we’re all different. I think there isn’t one definitive answer. How did you feel on that 58cm frame? Did you try the 60cm size as well? I’d listen to my body first and then to Trek’s charts and go for the 60cm frame if I’m not sure. 🙂
I bought a bike that was tall enough but the distance between the seat and handlebars is too close and not a comfortable ride. Is there a different measurement for that?
Hi Mekay, what you’re talking about is called “reach” and refers to the “length” of the bike. If you feel that way, you need to put a longer stem and perhaps lower the handlebar a bit. It’s best to consult with someone experienced in bike fitting.
Hi Jeff, I’m looking at buying a mountain bike and can’t go in to the store to try. I’m 5’7 (168cm) with a 30 inch inseem.
Would a 16” frame be too small? The next size up is 18” but I really don’t want to be straining on my tip toes if I need to stop!
Thank you!
Hi Jake, I think a 16″ frame could work, but without knowing the exact bike, I can’t help you more.
Hi, I am looking to replace my bike and have seen an 18 inch road bike on eBay that is within range for me to collect. Being a 6 foot 1 male would this be the correct sort of size to go for or is is not right for me.
Hey Josh, road bikes are generally measured in cm, not in inches. Still, at your height, you’d need a 19″-20″ bike. So, the one you’re looking at is one size too small.
Hello Jeff,
That a nice guide, but being new on bicycle reading I’m confused if for touring bike I must relate to road bike?
I am 180cm with leg inseam 80cm.
A 54cm size frame bike would work well for me?
Thanks
Hey Enn, a 56cm size frame would work a lot better. Touring bikes have similar geometry as endurance road bikes, so the sizing is similar.
I’m 5’9, inseam 32 inches. Found a great entry level road bike at 54 will this size work for me or donI nee 56
Hey Michael. It will work. 🙂 You might have to put a longer stem and perhaps lift the handlebar a bit. But it all depends on the bike’s current setup.
Hi Jeff! Thank you for the article! I’m looking to get my first road bike. I’m about 5’10’ with a 78.5cm inseam. Many side charts have me between a 54 and 56 – if I’m looking for a more comfortable/less aggressive ride, what would be my best bet size wise? Looking at either Felt,Scott, or Fuji. Thanks for the help!!
Hey Thomas, I’m happy you find it helpful. 🙂 I’d go with a 56cm frame, it should put you in a more upright and comfortable position, which is what you’re looking for.
I am completely overwhelmed looking for a bike. I have no idea what to look for in a bike. I am 5 foot 5 with a 30 inch inseam. What size would I need? What would you recommend for doing trails with the family?
Hey Wendy, I believe a 16″ frame would be a good choice for you. 🙂 I recommend you check out our recommendations for the best cheap mountain bikes here and here. Any one of these would be a good choice for family trail riding. 🙂
Hello! I am looking to get my first road bike, but currently my local bike shops are all closed. I’d really appreciate your recommendation. I am 5’1″ with an inseam of 26 inches (short girl with short leg problems). Would a 42cm frame be too small? I was also looking at another bike with a 47cm frame. I’m worried about the top tube being too high and uncomfortable. I’m used to riding step-thru bikes, so the top tube is new to me.
Thanks for any help!
Hi Toni. You should be able to fit on a 47/48cm road bike without any big problems. Just make sure that the standover height is under 26″, you can find that measurement in the geometry outline of the bike. A 42cm will be too small for you.
im 5’0 and im short too with short legs. I got a junior size 44 and its good for me. I feel comfortable
Hello Sir!!! I have been looking for my first bike…I am 46 you and 6’1 with a 32″ inseam. I have looked for a Giant Fathom 2 and now I think I need a hybrid…I have found the Trek Dual Sport 4…But it is sold out everywhere in the Large. There is only an XL available. Will the XL bike be too large for me or am I in the transition area? I know the measurements overlap at times.
Thanks,
Jeff
XL should work for you. Check out the size chart on Trekbikes.com.
Hi Im 59
it this bike a good fit: Womens Mountain Bike, Adult 26″ Trail Runner Outdoor play
According to Huffy, it fits riders between 60″ and Adult height. I can’t give you a more specific answer because the available information is quite vague.
Hi Jeff,
Great site lots of wonderful insight and information, I am 57 4’11” inseam 61cm Can you please recommend a bike for riding back and forth to work. Nothing serious I would like to sit up and not be all hunched over like my last bike. The sizing I am reading is xxs or xs for a city bike. Please assist as I don’t want to spend money foolishly.
Hey Jeanette, I recommend getting a cruiser or a hybrid. You can check our resources about the best cheap bikes we recommend here and see if you like something.
Electra Townie could also be a good fit for your needs. 🙂
Hi Jeff,
I am looking for a bike for my daughter, sadly due to the isolation we can’t try the bike on. She is 5’5 or 165. She will be learning on the bike, too. I saw some youth bikes with 20”- will they be too small? Should I look into the adult sizes? It would be for a regular rides around the block, which I think mountain is? What size would she need? I am 5’10 myself with 31 inseam, and can we ride the same bike?
Thank you!
Hi Beata! Your daughter will fit nicely on an adult bike, she is more than tall enough. You can get a mountain bike, a cruiser, or a hybrid bike, any would be a good choice for a few miles here and there. As far as sizes go, I recommend a 16″/52cm frame. 🙂
Jeff –
Can you help please? I have two kids that I want to get bikes for. Just for riding around on paved trails, to the store, out to lunch, etc.
My 14 year old growing son is 5’9″ with 32″ inseam (81cm)
Test 1: Bike size 16-17 (is this frame or tire size?)
Test 2: 21″ (is this frame or tire size?)
Test 3/biker’s guide: 17 – 18″ frame
Does that mean 21″ tires and 18″ frame would work for him?
My 12 year old daughter is 5′ with 29″ inseam (74 cm)
Test 1: Bike size 13-15 (is this frame or tire size?)
Test 2: 19″ (is this frame or tire size?)
Test 3: 14″ frame
Biker’s guide: 15 – 16″ frame
Does that mean 19″ tires and 15 or 16″ frame would work for her?
What type of bike would you recommend?
I am getting confused on finding one online (can’t go to retail stores to try them out). Most give a tire size, not a frame size.
What is a reasonable price for the bikes?
Thanks!
Hey Kathy, bike tires exist in the following sizes:
Kids’ bikes: 12″, 16″, 20″, 24″
Adult bikes: 26″, 27.5″, 650b, 700c, 29″
When talking about kids’ bikes, we only take the wheel size into consideration to find the correct fit, NOT the frame size.
When talking about bikes for adults, we talk about both wheel size and frame size.
All of the measures you listed in your comment refer to frame sizes.
As for choosing the correct size for your children, I’d recommend an 18″ frame size for your son and a 14″/15″ frame size bike for your daughter. Your son can ride a bike with 700c or 29″ wheels, whereas I recommend 26″ or 27.5″ wheels for your daughter.
Hope this helps. 🙂
Hi…. I am after a sizing for a MTB for my 13 yr old son. He is 173cm tall with a 83cm inseam… ?
I may use the bike too occasionally. I am 179cm with a 80cm.
What size should I consider ? Thx
Hey Tony, a 17″ frame would be a good size for your son and you could ride it as well occasionally. Have fun!
Hi! I’m all the way from the Philippines! I’m 177cm tall and have a 79cm leg inseam. What size of a bike should i get? Thank you! 🙂
Hello Philippines! 🙂
It depends on what type of bike you want to buy. If you’re looking for a MTB, I recommend a 17″ frame. If you want a road bike, a 56cm frame would be a good choice.
hi there.
i am looking at a raleigh skyline hybrid, 19 inch. i am 5’10 and i swear my inseam was around 29/30. the charts say everything from 17-19 inch bike would be good. could you help with some advice. wondering if you think this 19 inch raleigh would be ok? thanks so much!
Hey Heather. A 19″ frame would be an excellent fit for you. Happy riding!
Hi Jeff, great article BTW.
I’m 171cm in height, and have an inseam of about 29.5 inches. I’ve seen a 2020 Trek FX 2 Disc Mens Hybrid Bike, the medium frame is 17.5″. Would this be ok for me, as I can’t go sit on it. The one below is a 15″. I’m unsure what to go for. I’m pretty new to biking.
Thanks mate.
Hi Mike, glad you like the article. Yes, 17.5″ is a good size for you. Half an inch will not make a big difference. Enjoy!
Hello Moderator,
Please kindly advise, I am 183cm tall and with an inseam of 90cm. From you chart I realize I will need a MTB of 21 inches (52cm) Frame and for a Cross bike i will need a bike with about 60cm frame. Unfortunately the cross bike I will like to buy is only available up to size 58cm with 28cm tyre size. Can you please advise with your discretion if this will be ok. Here is the link to the bike am considering.
https://cube-store-weiden.de/cube-fahrraeder/cube-trekking/cube-nature-exc-greennorange-2020.html
Yes, 58cm would be the perfect frame size for you. 🙂
Hi Jeff, Thanks for the article. I’m 180cm tall with an Inseam of 78cms. Looking for an MTB. From the chart I should go for an 18″ . The specific bike I want to purchase comes in 17″ and 19″ which size should I go for?
Hey Kagira! The larger, 19″ frame would be a better choice. 🙂
i’m trying to figure out the best for two of my daughters that are close in size and i’m a little confused about the types of bikes. I’m looking for bikes that my girls can use to ride to school and back and around town.
My daughter are the following:
13 Years Old: 30 inch inseam and 63″ height
14 Year Old: 28″ inseam and 62″ height
Since they are close in size i’d rather get them a bike on the larger end so they have for longer.
I also have a soon to be 6 year old: 19″ inseam and 44″ height.
Your advice would be very helpful.
Hey Moshe. I believe a MTB with 26″ wheels and a 15″ or 16″ frame would be a good choice for your daughters. Your 6-year-old would need a kids’ bike with 16″ wheels. 🙂
I am looking for a mountain bike for my son who is 4’9″ and has a 27″ inseam. Is he still in the range of a 24″ kids bike? I’m having trouble figuring out where that ends. And if not, what is the next size up? It looks like some bikes start at XXS and others at XS.
Hi Jennifer, your son is at the upper limit of kids bikes with 24″ wheels. I recommend going for a 15″ frame with 26″ wheels. That will give him some room for growth as well. 🙂
Hello,
I am looking for the right bike to buy, it will be used for general riding with my family. I am 6’3 and about 370lbs and have a inseam of 30″ any info you can provide that could point me in the direction of what size bike I should get would be awesome!
Hey Scott. Most mountain bikes have a maximum weight limit of 300 lbs. So I would recommend getting a fat bike (those bikes with massive tires) with a steel frame. If you want an e-bike, you can check out Rad Power Bikes and their RadRover model, we wrote about it in this article. 🙂 As for the size, a 19″/61cm frame would be a good choice.
Hi there. I rode a 48 cm Bridgestone XO1 until it was stolen two years ago (broke my heart) and I’m looking for a bike that is a similar ride. I found a Trek 950 8744 48 cm at an honorable used bike shop but they say the standover height is 31.5 and they say it will be too big for me. 5.5 on a good day. Can’t try it out because of stay at home. They are trying to sell me smaller bike. I measured my inseam roughly at 29 (kind of hard to do on your own) what do you think? Last year I test rode a Bianchi 49 cm but didn’t buy it because it felt so different from my beloved Bridgestone. Should I pop the large sums of money I will have to borrow to replace my Bridgestone with Bridgestone? Will I ever find a comfortable bike again? This is an awesome resource by the way. Thank you.
Hey Sally, so sorry to hear about your bike!
If the standover height is that much higher than your inseam length, I think that Trek would not be a good fit. If you plan to ride often and ride long, spending some extra money on a bike that you like and enjoy is a good investment. 🙂
Hi trying to choose between a 21 inch frame and a 19 inch frame. I’m 6’2” with a 33” inseam. Also I don’t want to have to ride with the seat jacked way up as it’s harder on my back.
It depends on what type of bike you want to buy. But, it seems like the bigger 21″ frame would be a better choice for you.
Hi! What is the difference in the numbers for bike sizes? The last bike I had fit me vertically but the frame was way to stretched out horizontally in a way that was uncomfortable. How can I compare the numbers given online to figure out what would fit me best/how is the horizontal stretch communicated?
Thanks so much for the article!
Julia
Hey Julia, the “horizontal stretch” measurement you’re talking about is referred to as “reach” and “effective top tube length” (they’re not the same thing). Perhaps your torso is much shorter than your legs? For most people, just fitting a bike according to their height is a good way to go, but some people have uncommon body proportions. 🙂
Hi Jeff.
Just read your article and saw all of the reply’s and your responses to them all so thought I’d ask.
I’m 5ft 7 with a inside leg of 29 inches.
I’m looking at an electric MTB.
Can you let me know what size frame would suit me and is it better to go a bigger or smaller frame if I can’t get the right size also would a 29er be a different size for me compared to 27.5
Many thanks
Hey Bryn, a 17″ frame would be a good choice for you. 🙂 29″ and 27.5 bikes don’t differ much, except for standover height. The distance between the ground and the bike’s top tube will be higher on a bike with 29″ wheels compared to 27.5″ wheels even if the frame is the same. But other dimensions stay the same.
hi jeff, i want to ride a bicycle as a new hobby, my choice is road bike. my height is 154 and my inseam is 75, is the bike with frame 52 suitable for me?
Hey Jun, I’d say that’s too big for you. A 48cm frame would be a much better fit.
Hi. This was a very helpful article. I’m 5’3″ and this makes me think it’ll be ok to order a girls bike.
Glad you liked it!
Hi Jeff,
I’m looking for a bike for my girlfriend, she’s about 5 ft 2/3 and I’m not sure what frame / wheel size she needs for a mountain or road bike?
Also along with this, she has never ridden a bike before so I have suggested potentially using some stabilizers, what are our thoughts on this and how I can help get her riding?
Your help would be so much appreciated 🙂 Thank you
Hi Anand, a 15″ MTB or a 50cm road bike would be a good fit. I wouldn’t recommend stabilizers, I don’t think they are a good way to learn. I recommend going to a park with grass and trying to ride there. You can try lowering the seat as much as possible at first so she can just push with her legs and try to coast while balancing before trying to pedal. 🙂
Hello, I am right at 5 foot 10.5 inches tall. My leg inseam is 29 inches (73.66cm). I have been told I have a longer torso than most people my height. I’m trying to figure out what a good mountain bike size would be for me.
Hey Dan, I’d go for a 17″ or an 18″ bike frame.
Hi, great article, thanks so much!
I am 166 cm and have long legs (77,5 cm inseam) and therefore shorter torso.
How do I choose my bike size, either hybrid or road?
Many thanks
Hi Sara, you’re welcome. I’m glad you liked it. 🙂
You can get a 52-53cm frame and install a shorter stem to create a better fit for your shorter torso if necessary.
Hi Jeff
your article is absolutely awesome. Can you help me to select a bike? I am 6.44” and I can’t decide what bike I actually buy. Already I discuss with many people but I do not agree with their proposal.
Hey Nick. If you’re looking for a mountain bike, I recommend going for a 21″-22″ frame. If you need a road bike, a 60-62 cm frame would fit you well. 🙂
Hi, my son wants to build a bike and Im guessing that we start with a frame. He will mostly do paved riding with a few trails so I believe a hybrid is best for him but size has me confused. He is 16, currently 6’3″ ….but may still grow a couple of inches and is currently about 170 lbs. Can you steer me in the right direction? My goal is to equip him with a few of the larger parts and make him figure out the rest….totally within his ability. Thanks!
Hey Cindy! It’s amazing your son wants to get some grease on his hands this way! 🙂
I agree that a hybrid would be the best choice. I think a 60 cm (21″) frame would be a good choice that would give him some room to grow as well.
hi jeff.
i want to start riding again
and i have already a bike but, the bike was fit for me when i was 5′ 10″ and the bike size is 18in frame, 27.5in wheel but now im 6′ 3″ and 92cm inseasm with 8in apart between feet i want to know can i still use mine or i should buy one?
I think a 19″ frame would be a better fit, but if you don’t feel any issues when riding then you can stick with it for a while more.
Hi Jeff,
Thanks for the explanation of the bicycle types. Now with the wider range of possibilities, I am not sure what I want to choose. My original research was to determine the difference between the mountain bike and the folding bike design(smaller wheels and longer poles) and which would be easier to use.
My aim of getting a bike is to get from one part of the city to the other but because there is so much construction and roadworks everywhere, its is not smooth tarmac I’m riding on only and I was mainly considering a MTB because it’s the only one I’m familiar with back in the 80s/90s.
But as I read further down the bike varieties, the folding bike(which is a more common type I see in the public these days), city bike, and hybrid bike. Each had a feature of the purpose I was looking for. I also want to be able to hold a small amount of items when I go around, so I was thinking the city bike design would help.
So far those are the types which also have prices that start off affordable for me. But now it is the confusion of selecting which type but I’m a bit closer to either MTB or hybrid. I was thinking the multiple gear/speed would make it easier to start cycling from stationary when at traffic junctions.
So if I was about 65 with an inseam of 29, which size and type would fit my requirements the best? Thanks for your help.
Hey Lionel! Glad I could help! 🙂
I think a hybrid bike would definitely meet your requirements. It’s great for city rides and for mild off-roading. You can get a decent hybrid bike for occasional use for as little as $500, or you can spend more for a higher-end model.
As far as sizes go, I could help you more if you told me your height. But, relative to your inseam, I’d recommend a 15″/52cm bike. Have fun! 🙂
Hi,
I’m helping my boyfriend find a road bike. There is a 2010 track madone 4.5 WSD road bike 51.1cm. He is 5’8” with an inseam about 29” or 73.5cm. Would this fit him? It’ll be his first road bike and planning to just ride about 50-60 miles a week.
Hi San, I’d say that’s too small for him. His ideal size would be 54cm.
Hi Jeff,
If 51.1cm is too small for my bf and ideal size would be 54cm, but currently I am unable to find a decent road bike that’s 54cm. Would a 52cm be a better second choice where he could just adjust the saddle or would a 56cm road bike be okay? Please and thank you!!!
If you had to choose a different size, I’d say a 56 cm would be a better alternative. I definitely don’t recommend a 52 cm frame at that height. 🙂
Hello, Jeff
I need advice on choosing a bike. I’m 178 cm tall, looking for mtb hardtail, I’m thinking about 29er frame size L I think it’s 19” , can it be to big for me? Or I should choose 27,5er?
Thanks in advance 🙂
Hi Donatas! I think a 17″/18″ frame would be a better fit. I’m worried the standover height on a 19″ 29er would be too high for you, among other issues.
Hi, Thanks for this post. I’m new to the world of bikes and was hoping to get my first Bike. I’m 5 10″ tall and would link to know your opinion on the bike in the link below.

Thanks again
I’d say it’s a decent buy for the money if you plan to ride recreationally. 🙂
Hi Jeff – this article is very helpful however, I am still feeling daunted about picking the right bike for me. The last time I tried Citi Bike, my feet could not reach the ground and I’d have to immediate jump off it or else the bike and I would topple over (my feet didn’t reach the ground). This typically would be find in a quiet suburb but not on the bustling bike lanes of NYC!
I am JUST about 5’0″ and according to the measuring chart, have an inseam of 28. I’m interested in a hybrid bike (something I can take on the road but also on a trail) and not looking to spends thousands of dollars for a customized bicycle. Do you have any suggestions on what might work best for me?
Thanks in advance!!
Hey Mary, I assume the standover height on your previous bike was too high. You should aim to get a hybrid with a step-through frame which would take care of that issue. How about Sixthreezero Evryjourney? We wrote about it here, along with other affordable models.
Thanks for the reply!
I found the sixthreezero EVRYjourney and Around the Block on Amazon, each have a 24″ and 26″ option. Three questions given my height (barely 5’0″) and inseam (28):
1. For the EVRYjourney, can I get away with 24″ or is 26″ be more appropriate?
2 – It appears as though the Around the Block bike pedal positions are higher than the EVRYjourney, so would the 24″ work better for that model? (I would think it would allow me to touch my feet to the ground)
Thanks in advance (again)! I love your site. Very helpful.
I still recommend going for 26″ on both models, you’ll fit well on them and 26″ wheels ride much better than 24″.
Hope you find this helpful! 🙂
Hi Jeff,
Thank you very much for this much needed article. I am still a bit confused because I fall on a margin. I am 168 cm and the inseam measure is 78 cm. I am a lady and looking into buying a Scott Sub Cross 40 Lady. Shall I get an S or an M?
Thank you.
Ran
Hey Ran! Both would work, but I believe the Medium-sized frame would be a much better fit for you. Have fun! 🙂
Hi! Thanks a lot for all this info!
I’m trying to get a Mountain- enduro Bike for me and for my girlfriend.
She’s 167 cm Weights 64 kg and this would be her first ever bike. We saw a 2017 cannondale habit 3 women’s small frame and 27.5 tires . Do you think is the right size ? Too small maybe ?
This is the bike https://www.facebook.com/marketplace/item/580704962653397/
I’m 177 cm 82 kg and I saw a Santa Cruz heckler large frame 27.5. It would be my second bike . Good size?
https://www.facebook.com/marketplace/item/646850659440366/
What do you think on the prices ??
Hi Gonzalo, you’re welcome, glad you found it helpful!
I think your girlfriend would fit better on a medium-sized Habit 3. Small is recommended for up to 165 cm tall riders.
As for you, Large frame should be a good fit. 🙂
Unfortunately, I can not enter that Facebook market, so I can not provide any insight on the prices. Plus, gauging the price of a used bike without inspecting it in person is very difficult.
Great Article. I feel like I’m stuck in between sizes. I’m 175cm and my inseem is around 78.5cm (31 inches). I know theres a difference between mtb frames and roadbike frames. Can you suggest me a good size for both types? Thanks
Hey Milhan! You’re right, you’re right in-between two sizes. I recommend going for a 56 cm road bike frame or a 17″ MTB frame. Both should be a good fit. 🙂
I’m looking for a cruiser. I have short legs and a long torso. I’ve had a very hard time finding a bike that fits. I am 5’6″ with a 28.5″ inseam. I currently have a 26″ Huffy. I can barely touch the ground with my tip toes or my knees are in my chest. Please help me. This is the first bike I’ve had since a teen. Thank you!
Your inseam does not really seem to be too short compared to your height. I think an M-sized hybrid (16″/54 cm) should be a good fit. To fit the bike even better, you could fit a longer stem to accommodate for your slightly longer torso. Hope that helps. 🙂
I’m looking for my first bike in decades. My momma had a custom made one n 2007/2008. I can’t think of the brand by the frame says ‘Allox Butted’ (I think, it’s half worn off) on it. It is a 7 speed bike. She is a few inches taller than I am, and have tried to ride it in the past and one foot always slips off the pedals. My uncle even removed the back light (as I would only be riding around my street during the day, when only a few cars come through all day) so he could lower the seat for me. This did not help any, and I still had the problem. When I was a pre-teen/teen (1990s) I had a 10 speeder that I fit on fine. Again, I can’t remember the name or anything but it was sold by the big box stores. My gramps had an old bike from the 1960s/1970s or so that I would ride to and from work with no issues and believe it was a road bike; I could be wrong though as it looks (just from photos) a lot like a Schwinn Wayfarer Retro Hybrid.
I’m not sure which type of bike I would need – as I would just be riding around the streets/sidewalks (I know you aren’t supposed to ride on sidewalks, I just don’t feel as safe in the streets) – but I like the grip on mountain bikes. Would I go for a hybrid bike? When standing are your feet supposed (or straddling the bike) to be flat on the ground? I’ve notice with the one my momma has (she doesn’t ride it which is why I was going to take it off her hands lol) I would always be on my tip-toes. Yet the other two bikes I mentioned, if I remember, my feet were flat on the ground when just standing/straddling the bike.
I am a female, 4’11-5’0 (149-152 cm) with an inseam of 24″ (58 cm). Thank you.
Hey Valerie! I think a cruiser would be a good fit for you. You can check out Electra Townie, we wrote about it here. I think it would be a good fit for your height and your requirements.
Otherwise, any hybrid/mountain bike with a 14″ frame and 26″ wheels would be a good match. When you’re off the saddle, your feet should be flat on the ground. However, when you’re sitting on the saddle, you should not be able to reach the ground without leaning the bike on the side a bit.
Hope that helps. 🙂
Jeff,
Thank you so much for the reply. I will check out the link you gave and copy the information as far as wheel size, etc goes so I know when I start looking offline. I thought my feet were supposed to be flat when standing but whenever I mentioned that, people just told me I was wrong and that just can’t balance right… and it never made sense lol. So happy I found your site 🙂
Happy I could help!
Jeff,
I have another question. I am looking to stay in the 250-300 price range but as I am still researching, etc that price may go up once I find something I like. You mentioned a 14″ frame and 26″ wheels. I am having a hard time finding a bike with both; on Amazon (for example) you can choose the wheel size but not the frame size. Even going by their sizing, that would be an XS frame, and I can’t even find the option to select frame size at all, just wheel size. Am I just not searching correctly, or would these be custom measurements?
It depends on which bike you’re looking at. Some have a one-size-fit-all frame and just differ in terms of wheel size. Getting the smallest frame available (whether it is XS or XXS) with 26″ wheels is a good way to go.
Hey Jeff,
I’m 5’9″ (right in the middle of two different sizes) and am trying to find a bike that would work both on paved roads and rougher gravel. No real intention of off-roading / mountain-biking. Do you have any sizing preferences? Should I go for the Medium or the large, since I’m in the middle?
I’m budgeting in the $500-700 arena (give or take a bit on either side) for a solid bike that fits my needs. Do you have a recommendation?
Thank you!
Hi Peter, a Large frame is definitely a better option for you since you’re in-between the two. As for recommendations, I think that any hybrid would meet your requirements. A gravel bike would be an even better match (such as Salsa Journeyman 650 Claris or Pure Cycles Gravel Adventure), but that’s slightly above your budget.
Hi..I would to buy a bicycle …my leg inseam is 75cm . I was riding a bicycle since 25 years and now I want to buy one. But I need it for a beginner and road bike. So what size should I buy for lady?
Hi Rima. I could have helped you more if you told me your height as well. But, judging by your inseam length, I’d say you should go for a 52-53 cm frame. Enjoy!
Hi I am 5″7 and an inseam of 29 I would like to start cycling for weight loss purpose. I am considering a hybrid. Your article is very helpful to help me find what I am looking for. I am basically starting out but my question is with me being overweight what size tires should I consider? My weight is over the 300 lb mark. Could you please help me to decide so I could start this new adventure.
Hi Kimberely. Almost all hybrids come with 700c wheels, so you should choose a model with wider tires, such as 40 mm and above. You can also consider some MTB model, they’re sturdier and will be able to carry 300 lb without any problems. 🙂
Hi Jeff,
I was thinking about getting a Cannondale Mountain bike. I was looking specifically at a trail 3 or 4. I am 5’9.5″ with a 32″ inseam. Their site says I should get a large but I am concerned about the standover height. The large has a standover height just over 32 inches. Should I be concerned about this? Am I definitely a Large? Should I be looking for another bike with a shorter standover height?
Thanks
Hey Matthew! I think you should get a Large. The standover clearance should not be an issue since you’ll be adding an inch to your inseam length when you put your shoes on. So you should have just enough. 🙂
I’m a 61 yr young male , 5’8 with a 28” inseam looking at a Specialized Turbo Como low entry…due to hip issue.
Would the small size fit? Or would you recommend large?
Thanks!
Hey Kelly! I believe an M-sized frame would be a good choice for you. L could work as well, but you might feel a bit too stretched out. 🙂
Casual rider – looking for a new bike. I am 5’1 with 29″ inseam. Can you advise on frame for me since I am petite?
Hi Joanna! If you’re planning to get a mountain bike, I recommend a 15″ frame. If you prefer a road bike, then a 50 cm frame would be a good fit. Enjoy riding! 🙂
Hi Jeff,
I am planning to get a Trek Dual Sport 2 (2020) but not sure about the size (will order online). I am just shy of 6″1′ (184 cm) tall, and inseam of about 34-35 inch. This is the first time I am buying a bike and not really sue how to get this right. Which one would you say I should go fo – L or XL? Thank you so much!
Hey Arber! I recommend choosing the bigger XL size since you’re right in-between two sizes. If you’re taller than 5’6″, it’s better choosing a bigger size when you’re in-between two. 🙂
Thanks Jeff! Guys at Trek suggested I go with XL, too. The order is in!
Cheers 🙂
Enjoy your new bike! 🙂
Hi Jeff,
I am 5’4″ with an inseam of 29.5 inches. I looking at hybrids or mountain bikes. I mainly want a bike to ride around neighborhood streets but be able to take occasionally on dirt trails at local parks. Can you suggest styles/brands (that are a good value) as well as sizes. I appreciate it!
Hi Kathleen! Please take a look at our recommendation for the Best Bikes for Commuting and Best Hybrid Bikes, we wrote about our favorite styles and brands. There are bikes of all price points and you can’t really go wrong whichever you choose. 🙂
Hi Jeff
I’m looking at a gravel bike. Cannondale or something equivalent. I’m 5’6″ with 29″ inseam, female in mid 40s. I cycle regularly but current have trek urban bike I take to work that’s 14″ 34.5cm. My mountain bike is old and uncomfortable and clearly not the right fit.
For road bike I feel like I’m somewhere between a small and med frame. Since getting a proper fit will be challenging with COVID19 restrictions, any recommendations on proper size. I’m anxious to get something and kicking myself I didn’t buy last fall.
Thanks! Beth
Hey Beth! Gravel bikes are sized similarly to road bikes. I believe a 54 cm frame would be the perfect fit for you. Btw, that 14″ frame is definitely too small for you! Have fun riding gravel! 🙂
Hello,
I am interested to get Canyon Ultimate CF SL Disc 7.0 , my inseam is 74cm and i don’t need my leg to touch the ground while stopping. Usually I stand on the top tube. Which size is correct for me?
Hi Ayoosh, it’s hard determining your ideal frame size without knowing both your height and your inseam length. However, just measuring by your inseam, I’d say you’re ripe for a 51-52 cm frame. That would be the M frame on Canyon.
Hi, I’m 5ft 8, and looking for a road bike that will suit me. Been looking online for a bike. Just getting confused with the titles of the bike where they have numbers in inch. Is that the frame size? And which size should I look for? TIA
Hi Raad, your ideal road bike frame size would be 55-56 cm. Road bikes are not measured in inches but in centimeters. When it comes to mountain bikes, the wheels are sized in inches (27.5 in., 29 in.), as well as frames (16 in., 17 in., etc.).
Hi,
I’m looking to start riding a road bike to work, specifc a felt FR, or a Canyon Endurace.
I have a short torso, being 181cm’s tall and having inseam of 88cm, my arm length is also like an orangutang.
In terms of the Felt should i go for a langer frame 58 over the recommended 56, then refit it with a shorter stem, trying to avoid too much seatpost compensation?
So my limbs are long, is it then better to go up a frame size and reduce the stem-length. This to avoid backpain from a very high seatpost position if I went for the smaller frame?
BR Christian
Hi Christian! Yes, you’re thinking in the right direction. The saddle/handlebar height difference would be too extreme on a smaller frame with such a long inseam length. A 58 cm frame should do the job. If you can, it would be a good idea to pay for a professional bike fit. They’ll change your stem and do any other necessary adjustments. 🙂
Hi
I,m 5ft 1 with a 28 inch leg!
Would I be able to fit correctly on a girl’s 17inch frame with 24 inch tyres?
Thanks
Gemma
Hey Gemm! I think you might find that bike to be a bit too small for you. I believe a bike with 26″ wheels would be a better fit for you.
I’m 198cm tall with an inseam of 92cm. I’ve measured my standover height at 78-81cm. I’m looking for a Hybrid/Road bike. I’m having trouble finding bikes with the right size pairing of for the wheels and the frame. Any suggestions?
Hey Mike, I can’t suggest any specific bike because I’m not familiar with your preferences and budget, but any hybrid/road bike with a 20″/21″ (62 cm) frame would do. 🙂
Please help. Researching best size for my 9 1/2 yo daughter and I’m so confused by the different charts on the web. She’s 52″ tall, 27″ inseam. The kid cruiser bikes (Huffy) I see only refer to wheel size. I was leaning toward 24″ wheels but am thinking we won’t be able the reach the floor. Do I need to go down to 20″?
Hey Susan! I think your daughter will be able to ride a 24″ bike. The approximate inseam requirement for 24″ kids bikes is 23″-28″, whereas the approximate rider’s height range is 50″-60″, so she falls right within. 🙂 Btw, kids bikes are generally sized relative to the wheel size, not to the frame size, as is the case with adult bikes.
Hi there! I am 5’6, and my inseam is 29. I am looking to get the santa cruz 5010 or the tallboy! I am having trouble figuring out if i will be a Medium or a Small. The 5010 does have 27.5” tires and the tallboy does have 29” tires. Can i get a suggestion?
Hey Anthony, I recommend choosing the bigger, Medium size. That’s what Santa Cruz’s charts for these bikes recommend as well. Have fun! 🙂
Hi so I am 5’9” inseam of 32 what bike would be the best for me? I’m having trouble finding one without being able to go to the store!!! Please help!!
Hey Barbie, any 17″ (L) or 56 cm frame would be a good fit for you. 🙂
Hi Jeff! Thank you so much for your thorough explanation on bicycle fits. I am 5’6 & 3/4″ with an 30″ inseam. There is a used bike I’m looking at, Diamondback Vital 1, 15″ frame. Do you think this would be too small for me?
Hey Caitlin! You’re welcome. Glad I could help. 🙂
It seems to be half a size too small, but that’s not too significant if you’re not planning to ride too much or too often. Ideally, you should get a 16″ frame.
Hello
Im looking to order a bike online.
im 5’8 and looking to get KTM PENNY LANE 27.5 “- M (47cm),
but now after looking here this bike would be to small ?
Hey Bex! Mountain bike sizes are measured in inches. An M-sized Penny Lane is 17″, so that seems to be the right size for you. 🙂
Hello from Miami !
First off, Kudos to you for responding to all of the comments here! Due to all of the restrictions in place in Miami, traffic is minimal and we can bike with barely any cars on the road…unheard of here and a delight with kids. I am in need of a bike and this article was very helpful.
I would like to buy a bike online and this was helpful since I cannot try one out. What feature can I look for in a mountain bike (for casual riding) that will allow for more comfort in the reach to the handle bars? I do not feel very comfy when I have to lean too far down to reach them, over time, it aches my back…but I do not want a cruiser bike.
Is it the tilt of the handlebars, the height? Whatever feature it may be, are such features typically mentioned in the bike’s specific details/descriptions?
Any recommendations are appreciated. I am 5’4.5 with inseam of 30.25″ and it seems that I would fit on a 15-16″ , aka, size medium. CUrrent bike is size Small and a friend thinks I will be more comfy on a Medium.
Hi JB! I’m happy you find the responses helpful! Yeah, lack of traffic is a silver lining in this situation for all the cyclists out there. 🙂
I believe that you should be looking at hybrid/trekking bikes. You want a bicycle with a more upright geometry, without a big difference between the handlebar/saddle height. They often have wider tires (38 mm+) and front suspension, so you’ll get a similar experience as with a mountain bike.
Your friend is also right, a Medium-sized, 15″-16″ bike would be a better fit for you.
Hi ,
I have been looking at the Boardman hybrid bike – which is a 55cm frame size.
Looking at different websites its become confusing of which size I need. I know I am a medium in the road bike version.
I am 178cm and 32 inch inside leg. Can you help please???
Thanks
Alfie
Hey Alfonso, if you’re talking about the Boardman URB 8.9, then the M-sized frame would be the right fit for you.
Hi
Ive been looking at a Boardman hybrid sports mx race bike but I bit confused about the size to get.
I am 5ft10.5 and have inside leg of 32cm ish.
For the same bike in road version I know I need a medium. But I see different frame sizes for the hybrid version on different website guides. Would the 55cm Boardman frame be ok or to big???
advice please.
Regards
Alfie
Hey Alfie, I’ve answered your other comment without seeing this one. The 55 cm MX Race seems to be about the right size for you. Definitely not too big. 🙂
Hi Jeff!
Great website, thank you so much! It’s insanely helpful for someone like me who knows very little about bikes 🙁
I actually want a commuter/road bike cos I like speed but I might also choose a mountain bike, haven’t decided yet. I got a little confused with the charts though. I am 164cm and my leg inseam is 75cm. So if I go for a commuter, it’ll be 52 cm but with the mountain bikes, is it 20″ or 15″-16″?
Thank you!
Hi Gonca, I’m glad you find the website useful! 🙂
Yes, you are right. You need a 52 cm road/commuter bike or a 15″-16″ mountain bike. Have fun!
Hi Jeff,
I am 5ft 2″ and inseam measurement is 27″. I’m looking to buy a mountain bike and have found one that has a 14″ frame and 24″ wheels, would this be too small for me?
– Thanks!
Hey Tabitha. Yes, I’m afraid that’s too small. I recommend a 15″ frame and 26″ or 27.5″ wheels for your height. 🙂
Hi Jeff
I’m about to purchase CANNONDALE SYNAPSE HI-MOD ULTEGRA DI2 DISC ROAD BIKE 2020
I’m 1.75cm tall and have inseam of 80cm.
The shop assistant suggested I should get 51 size, however given the guidelines above, that seams small. He suggested it’s the right size given the fact they are modern methods for sizing.
As it’s a quite large investment, could I have your opinion, please?
Hi Jay, that seems too small to me as well. I wouldn’t go lower than 54 cm, considering your measurements.
Hi
I am looking at the Lapierre Aircode SL 900 Ultimate road bike in size XL. I am 196 cm tall and inseam 92-93 cm.
Do you think that can fit me, or is it to small?
Thanks
Hi Mads, I think it will be good since you’re right on the upper limit. After the purchase, I’d invest in a professional bike fit, just to dial everything properly. Great bike, btw! Enjoy! 🙂
Hi Jeff,
Loved your post., quick one! I am looking for a Road Bike.
You have matched 75cm against 5 to 5.3 height… My inseam its 75cm but I’m 5 ft, 7.3 in (171cm).
So just puzzled if I should go for a 50 / 51 / 52 / 52.5 (depending on the method I use!)
any help is greatly appreciated.
Best
Diego
Hey Diego, everyone’s body proportions are different, which can make bike fitting more complicated. In your case, I’d recommend a 54-55 cm frame.
I’m a 6’8” guy about 300lbs. I have a friend that said the cinelli hobootleg geo mtn 21” bike would fit me. I was wondering if you thought this would be a good fit for someone like me that would use it mostly on bike paths and around town.
Hi Austin, I think the size will fit you, but I’m wondering about the maximum load, as I cannot find any information about Cinelli Hobootleg. Try sending them an email and check if they think the bike can withhold that weight. 🙂
Hi! I am a pretty short girl, 4”11 but 26 years old. I just had my first bike ride ever this year and I’m looking to buy a mountain bike. I’m not sure if I should stick strictly to the sizes that is recommended for my height or if I can get away with slightly bigger sizes. I’ve been reading 24” is for my height but can I get away with something like 27”? Also, frame size recommends 14-15.
Hi Olivia, I don’t see why not if the standover clearance is lower than your inseam length. That’s what you should be worried about when thinking about different size wheels. Google these terms if you don’t know what they are and you’ll get a good idea of what I’m saying. 🙂
Hi Jeff!
My height is 178 cm & inseam is 83 cm.. I want to buy road bike Scott Foil. How would you recommend me? 54 or 56?
Thanks
Hi Paul, I believe a 56 cm frame is a much better fit for you. Enjoy your new bike! 🙂
Hi Jeff,
My height is 184-185 cm with 88-89 cm inseam. Should I go for 61 cm hybrid bike or a size lower one?
I’d go with a 58 cm frame in your case. 🙂
Hi Team,
Looking at ROAD Bike frames.
I am 1.73m Tall with a 83cm inseam.
Would a 54 Frame work for me?
Hi Andrew! Yes, that’s about the right size for you. 🙂
Hi,
So my inseam is 28”, looking to start road biking. I’m considering a Used Trek WSD 1000 as my first bike, I’ll be taking a look at it in the next few days when I’m in town. Figure I would reach out and see what you recommend? I should also note my torso is extremely short. For example, my legs are the same length as a friend of mine at 5’5 but I’m 5’1. From the many forums I’ve read on sizing, without being in store because my town is basically shut down from the pandemic, I should be either an XXS or XS. The frame size I’m considering doesn’t seem to match what is on this forum. Any help or thoughts would be appreciated as I am brand new to road biking!
Hi Rosalia, an XS frame (50 cm) would be a good fit for you. If you can find an XXS frame (48-49 cm) that would be even better, since your torso is shorter than usual. 🙂 Enjoy your new hobby!
Jeff,
I also read your review on the Cannondale CX3 and it also looks like a good fit. I see one in a Large. The REI website says that would be 5’10” to 6’1″. Might be too big??
Hello Jeff,
I really have to applaud you for your commitment to answering all of the questions that have been posted and that is really why I figured I would ask you. Your knowledge base seems really reliable as well. I am considering looking at/purchasing a Trek DS 8.4 17.5″ frame. I am 5’9″ with an inseam of 30.5″ to 31+” depending how high I go. What is your opinion on this fit?
Hi Keith, glad you like the content and find value in the website! 🙂 According to Trek’s charts, you’re right in-between the two sizes, but I believe that frame would be a good fit for you. You might have to make some slight adjustments, though.
To answer your question from the other comment, I don’t think it’s ideal, but definitely not too big. It could work with some bike fitting.
Jeff, I’m 6’3” 270 what size bike would you recommend? Thanks for your help, be safe out there!
Hi Craig, a 19″ MTB or a 60 cm road bike would be a good fit for you. Have fun! 🙂
Hi!
I’m 5’10 with an inseam of about 33.5.
it seems to be right on the borderline of being a medium or large mountain bike frame size.
any suggestions?
thank-you.
Hi Ike, I recommend going for the Large frame size in your case. Alternatively, you can measure your Ape Index and make a decision based on that. 🙂
Hi
I just purchased a used Specialized Sirrus Hybrid which is 54cm frame. I am 5’10” with 31″ inseam. Will this bike be the right size for me?
Thanks,
Roger
Hi Roger, that seems to be about the right size for you. Enjoy your new ride! 🙂
PLEASE HELP… I’m looking at purchasing the 2020 Cannondale Quick 2 bike. (Hybrid) I am 6 foot and a half, 32 inseam. I cannot go into the store because of CoronaVirus closing ALL stores by me. I need a bike ASAP. I’m stuck on what size to buy.. Large or Extra Large?? Thank you so much for your time.. I REALLY appreciate any input.
Kris
Hi Kris, I recommend going for the Extra Large size in your case. Enjoy your new ride. 🙂
Hi Jeff,
I am going stir crazy during the COVID-19 isolation & looking to buy a bike online – perhaps the Schwinn Freemont, I’m deconditioned but used to be athletic. I’m 5’4” & see so many ways to determine frame size. Is it better to err on the low or high side of the frame size. Most charts tell me 15” frame – inseam is 31” – any tips? Is this too much bike for me? the last one I had was a 10 speed Schwinn Racer (very uncomfortable) about 4 decades ago! I’ve just turned 70. Thanks for any suggestions… Stay healthy & safe!
Hi Constance! It’s great that you want to get back into shape again. We all need some fresh air during this isolation. I recommend a 15″ frame as well, I think that would be a good size for you 🙂
Hi Jeff. I’m a tall girl with long legs and a short torso. I’m 176 cm tall with 87cm inseam. Looking at a good road bike to ride with a group and maybe do a couple Sprint distance triathlons. Height wise I think I need a 57cm bike. But with my inseam I’m calculating a 61cm bike. I’m currently riding a 60cm men’s bike and it feels ok height wise. But the reach for the handle bars is too far. My calculated top tube length is 43.1-45.1. I’m having a hard time finding a women’s bike that’s tall enough and a men’s bike that has a shorter top tube length. (I think I said all that right….I’m new to this measurement stuff)
Hi Cheri, I can’t really recommend a specific bicycle because I don’t know your other preferences or your budget. However, I agree that you should go a size lower than 60 cm and fit the bike according to your torso.
Hi,
I am 7’1″ tall with an inseam of 40″ I once had a bike that fit me in college but that was 20+ years ago. Can you suggest a place where I can order one now?
Hey Dan, you’ll likely need a bike frame custom-made just for you. Try to do some research and see who does that in your area. However, that’s usually a pretty pricey option. Alternately, look for bikes with a frame size of 62 cm and above, they’re rare but you can find some used or new ones on eBay or Amazon.
Dirty sixer bikes will fit you. Shaq and Bill Walton and Nowitski all ride them. But $$$
Hi!! I can get my measurements later to get more precise on bike size. However I do know I am 5’4″. I am wanting to start riding outside of the cycle studio. Mostly paved maybe some flat dirt trails with a bike trailer with two kiddos. I’m thinking a Burley Trailer than converts to a jogging stroller as well. Why type of bike would you suggest?
Hi Carliza, a 15″/52 cm hybrid bike with 700C wheels and slightly wider tires would be a good choice for you. You could also look into some all-road/gravel bikes or even touring bikes. They’re all great for paved/unpaved surfaces and tugging a trailer along.
Hi Jeff
Thanks for creating this site.
I’m 6 ft and inside leg is 34 inches / 86 cm which based on the guides probably makes 58cm the right size road bike. However, I’m looking at Bianchi and they only come in odd numbers so would you recommend 57cm or 59cm? In case it makes a difference, I’m 50 years old and normally cruise round on a city bike so the body might take a while getting used to road bike position.
Thanks!
Rob
Hi Rob, I’d recommend a 57 cm frame size in your case. Have fun! 🙂
Hi Jeff, thanks for this.
I’m still apprehensive about buying without first trying for size, but visiting a bike shop is not an option at present due to Coronavirus . In case I get the bike and it’s not quite right, please can you advise which problem will be easier to adjust for – a 59cm that’s too big, or a 57cm that’s too small?
Thanks again
Rob
As I mentioned in my previous comment, I believe a 57 cm frame would be a good fit for you, according to Bianchi’s size guides. If, during bike fitting, you need to make any changes, I believe 57 cm is a better option.
Hi – I want to get an All-Road (Gravel) bike for my wife who is 5’3″ – 28″ inseam – 110 lbs. I figure her definitely in the Small or 50-56cm category. I was looking at the 2019 Salsa Journeyman 650b for her in 52cm.
Hi Oliver, 52 cm is the right size for your wife’s height and inseam length. Good choice of the bike as well! 🙂
Hi there. I am trying to get back in shape. I am 5’2 and weigh 200 lbs. I have a weaker left knee and want to find the right type/size of bike. Recommendations?
Hi Delaina, you haven’t really given me much information regarding what type of riding you’d like to do, how often, on what terrain, etc. A safe option would be a hybrid or a city bike with a 15″/50 cm frame. Have fun. 🙂
Hello Jeff,
I am 37 years old, 152 cm with aprox 66cm inseam. I believe, as you have said, that I need a bike 24″ wheel 14″ frame. right?or i can use a bigger one? To be honest I’m not sure what type of bike would be better for me , because I need it not only for going to work but also for any kind of road. London has plenty of hills.
I have found a Ladies Soul Beach Cruiser UK Fat Tyre Black Stomper
100MM BB WIDTH
170MM REAR SPACING
135MM FRONT SPACING
STAND OVER 27″
WHEELBASE LENGTH 49″
OVERALL BIKE LENGTH 77″
SEAT POST TO STEM 27”
SEAT TUBE LENGTH 18 ½”
WEIGHT / 1 Sp 45 LBS / 3 Sp 48 LBSs
but I am afraid that it is too big and heavy for me. What do you think? Also I have to tell you that I have back pain , it’s not severe though but I want to have the best control of the bike and best body position, so Ι am sure that a road bike for me it’s not good at all. Can you recommend me some bikes?
Sorry for the long text, and thank you very much in advance.
Hi Gia, I wouldn’t say a fat bike is a good choice in your case since you’ll be riding around London, which means paved roads most of the time. Fat bikes are intended for extremes, such as snow, sand, rocks, mud…
Instead, I’d choose a hybrid with a more upright riding position and 35-38 mm tires. That way, you’ll get a bike that’s easy on your back, and can tackle paved and unpaved surfaces. You can check here and here for some of our recommendations. 🙂
As far as sizes go, an XS frame with 26″ or even 27.5″ wheels and a step-through frame could be a good choice for you as well.
Hi, Please help!!!!!!!!!! Looking for a MTB for my son who is 10 and around 140cm tall. I dont want him to have a kids bike with 8 gears i’d like him to have 21 or above. Would a 13.5″ XS frame with 27.5 tires be ok for him?
Hi Dave, yes, it should work if you drop the saddle as much as possible. If he’s only going to ride to be active around the neighborhood, he should be perfectly fine. He’s likely to grow a lot more in the following years as well, so there’s nothing to worry about.
Hi Jeff, hope you don’t mind an additional comment / question.
I’m around 6’4” tall, used to be very fit but now wouldn’t run if I saw a lion on the streets. I want to change that but have severe arthritis in my left knee – that means that I can’t bend my knee as much as I used to be able to and so sold my old mountain bike because I would raise my backside from the saddle when the pedal was at the highest point.
My thought is that the best bike for me would be a cruiser on account of the more upright position, or a large mountain bike. Can I get your opinion please?
Thanks, Adam
Hi Adam, I’d go with a cruiser as well. Try to find one that has the pedals positioned forward relative to the saddle, such as on this Electra. That will take a lot of pressure off of your knees. Recumbent bikes might be a good way to go as well, but I don’t know how practical that solution is considering your needs.
Hi thanks for your helpful guide, just to be sure: I’m 5’11” and my inseam is 32ish. I’m thinking 55 or 56 frame size. I would prefer it be smaller than larger. Does that sound right? Thanks again.
Hey Bee, you’re right, a 56 cm frame would be a good fit for you. 🙂
Hi! I am a 5’5 woman and I seem to fall right in between on the size chart (s-m). Inseam is 30″ and I am looking at the Ghost Square Cross 1.8. Any recommendations for frame size? When one falls perfectly in between, what is the determining factor for best size? Thanks!
Hi Mary, in this case, your ape index is the determining factor. That refers to the ratio between your height and your arm span. If your arm span is longer than your height, you should choose the larger size, and vice versa. 🙂
Hi
i am 5’8 curently using ridley noah 52 xs, i plan to get another road bike but im confuse about the size, pls advice, thanks..
Hi Hakeem, you can’t go wrong with a 54-55 cm frame. 🙂
Hey Jeff, great website. My wife and I (both age 59) are getting back into biking after a long layoff, though we hike and lift weights regularly. We have older Trek hybrid bikes. Me a 21″ frame, she a 16″ frame. Our dimensions, I’m 6’3″, 34″ inseam and 37″ arms, she 5’3″. We are purchasing fat tire bikes with 29″ wheels. Getting her a Step Through frame that is 17″, and I’m considering a 21″ frame or would you suggest a 19″ frame.
Hi Tom. Thanks, glad you like the website! 🙂 A 21″ frame seems too large for your height. Once you switch to 29″ wheels, that could become a problem. Personally, I would suggest a 19″ frame in this case.
Hi,
I am 176cm, with 82.5cm inseam. What frames size do I need to use in mountain bike, road bike and TT bike?
Hi Sasa, your ideal MTB frame size is 17″, and for road and TT you should be looking at 54-56 cm frames. Hope that helps 🙂
Hello
I am Mina. I am researching about good size or common size for public bike sharing in defferenr country I would be grateful if you can help me about that.
Thanks alot
Hi Mina. Please send us an email at: hello(at)bicycle-guider.com or write to us on Facebook and we’ll gladly help you out any way we can. 🙂
I’m 6’3″ with a 34″ inseam. What would be the proper road bike size to start with? I’m leaning towards a 61cm.
My cross bike is a 60cm. Love the way it feels.
Hi Scott, 60-61 cm sounds about right for your height and inseam length. 🙂
I am 5’ 5” and inseam is 29 inches. I just got Trek FX2 Disc a 50 cm hybrid bike. Will this be okay for me?
Hi Arjun, that seems to be about the right size for you. If it feels good, enjoy the ride! 🙂
Hi, I am 6’3, 180 lbs, 37-37.5” cycling inseam. I own a 64cm Specialized Roubaix Expert but have the saddle all the way forward with the stock setback seat post and a 50 mm stem with rise. It looks silly but is fairly comfortable. I’ve tried smaller frames but the saddle to bar drop is too extreme. Do you have any suggestions? Is the short stem I’m using dangerous? Your opinion would be appreciated.
Hi Craig, if you have been riding with this setup for a long time and you have no problems, there’s no need to change it. You have quite a long inseam, so I believe it’s a good solution. Consider getting a seat post without setback for an even better fit. In that case, you could use a slightly longer stem and get better handling.
Hi, thank you for the article. I’m 5″7 and recently came across a 58cm Leader 735 bike frame. Would like to build myself a bike. It is probably too big and would it become a huge problem with my short height? I see small kids these days ride fixie way too big for them and seems not to be a problem. Thank you.
Hi Rivy, that frame is far too big for you. I wouldn’t recommend it. If you only plan to ride a few miles a day, it might work. But I wouldn’t recommend it for more than that. Ideally, you should aim for a 54/55 cm frame. 🙂
Hi! I’m trying to find a bicycle that I can ride to the grocery store and things since I don’t drive. I’m 4’11” and an inseam of 68 or 69 cm. So an xxs? What type of bicycle should I get? Im guessing a 24 in? I dont wanna spend an arm and a leg just for a bicycle to get to the store. I also have no idea what to get. Is 26 to big? That’s all I keep seeing when I look them up. I want to put a basket on the back for grocerys but really have no idea if all these bikes are just to big?
Hi Catherine, at that height, you’re right in-between two sizes. I recommend a cruiser for your needs since you need a basket and you plan to ride short distances. You can feel free to choose one with 26″ wheels and a 15″ frame. One recommendation is Electra Townie, which we recently reviewed and talked more about. 🙂
Hi Jeff,
I am 5’8′, and I rode a Linus Rambler that is 21 inch. I am buying now a Priority Continuum Onyx and according to their size charts I should get the 19”. I kind of got used to riding high and concerned about getting a smaller size, what do you think?
Also inseam is 31 inch
I recommend following the manufacturer’s size chart. Not all bike frames are made the same, so a Priority Continuum Onyx might be way too large for you at 21″.
Hey Jeff!
I think its great that you’re helping people find their forever bikes. I am a 5ft 1-2inch women and struggling very hard to find a bike that will fit me. Your article makes it seem like I should fit a 50cm road bike (inseam is 72cm) which seems… wrong according to other websites sizing. I’ve seen lots of sites saying that a 50cm is more for 5.5 to 5.8 people. I even found a site that suggested a 44cm bike for 5.3 to 5.7 people. I am so confused! Please help!
Hi Sami, bike sizing can be a bit confusing, I agree. The reason is that manufacturers still do not have a 100% standardized way of fitting their frames. Depending on the geometry of a bike and your body proportions, you might fit one size or another better. Considering your height and inseam, I believe a 49-50cm frame would be a good choice. But if you have doubts, it’s best to try the bike you’re planning to get (if that’s possible) and see how it fits. Happy riding! 🙂
Hi Jeff,
I’m a big guy, 6’6″ tall with a 34″ inseam. I’m looking for an MTB but am really confused with frame choices, especially as I am something of a specialist case size wise. What size frame would you recommend?
Thanks again for such an interesting site!
Phil
Hi Phil, I’m glad you like what we do! 🙂 Regarding your question, you need a 24″ mountain bike frame since you’re a pretty big guy. Most brands list them as XXL frames.
Hi, I am wondering what size of bike I should get. I am 5’7 1/2, inseam is 32in. Looking for a mountain bike. TIA
Hi Christina. My guess is you should go for a 17″ size frame considering those measurements. Good luck! 🙂
Hi Geoff
Fantastic article 🙂
I have been looking at mountain bikes (Vitus, Trek, Whyte) and am finding I sit between two sizes. I am 5’8 tall (bike size medium) but have an inseem of 28.5 inches (bike size small). Do you have any advice on what size I should consider seeing as I seem to sit between two sizes?
Many thanks,
Jon
Hi Jon, I’d say it’s better to go for size medium in that case. You’ll get a longer reach which will better accommodate your longer upper body. You can easily adjust the saddle height to fit the length of your legs. 🙂
Hi Jeff, I am looking at a Cannondale Synapse Neo e road bike to supplement my Specialized Roubaix Comp 2010 which is a 60cm frame. I am 191cm 6ft 3 inches with a 91cm 36 inch inseam. The Cannondale in the XL seemed way longer (reach) than my Specialized to the point I felt too stretched out despite long arms but they didn’t have a L to try. I now want to buy online but would value your input. I am concerned if I get the smaller L with a 53.5 cm seat tube Vs the XL with a 58cm I will feel cramped or worse still won’t get enough seatpost extension to suit my leg length.
Hi Tom, a 4.5cm difference on the seat tube length is not small, it seems like the XL frame on the Cannondale is more similar to your current Specialized. You could potentially shorten the reach by changing the stem for a shorter one and changing the fore-aft position of your saddle, so I’d go for the XL frame. Of course, it would be best if you could try the L frame as well and then make a decision. 🙂
Hi Jeff,
What frames size do I need to use for road bike if I am 183 cm and my leg inseam is 81 cm?
Hi Csaba,
You’re right in-between two sizes, but I’d go for the 58cm frame, considering your leg inseam.
Hi Jeff,
I’m a freak. I’m short(174 cm,5 feet 8.5 inches) with even shorter legs(insame 75cm,29 inches) and my bike feels very painful on my back(22 inches seat tube road bike). What size of road bike would you recommend? I used to ride only MTBs and I haven’t noticed my strange ratios on them, but i want to get faster, hence I’m trying to stick to road bikes now. Road bikes are maybe just not for me?
Hi Las, there is definitely a road bike for everyone out there. Don’t give up just yet. 🙂 Road bike sizes are always measured in centimeters, not in inches. I assume you have a 55-56cm road bike (equivalent to 22″), which I think is a good size for you. I recommend doing a bike fit to make sure that all of the parts are properly adjusted to fit your body and see how it feels after that. Good luck!
HI Jeff –
What size Cannondale Frame would work for my 12-year old daughter who is 5 foot one inch?? It is the Cannondale comfort hybrid??
Hi Emily, she would need the smallest size available on an adult bike with 700c wheels.
Thanks for your Info
I am 33 years, 92 kg., My height is 175 cm and leg inseam 84 cm.
Which frame is suitble to me? is it possible use wheel 29?
note/my city is so hilly ?
Thank you ☺️
Hi Saman. Assuming you’re intending to buy a mountain bike, you should be looking at 16″/17″ frames. A general rule of thumb regarding 29ers is that you should be at least 5’6″ in height (167 cm) to ride them comfortably, so I’d say you’re good to go. Just pay attention to the standover clearance.
Hi Jeff
I’m looking at the Merida Silex range and feel I’m stuck between Two Sizes could you please help.
I’m 168 cm with inside leg of 73.66. What do you recommend as maximum seat post height ?
I had a bike fit quite a while back and from crank to saddle I was informed of 673cm.
I feel both the small and medium. Merida silex could work they come in at 47 & 50 cm respectively. Any help gratefully appreciated. Thanks
Hi Vince, I’d recommend going for the 47cm frame, based on the information I could find regarding the Merida Silex range and your body proportions. The standover height on the 47cm frame is 731 mm, whereas on the larger frame is 760 mm.
hey I am 6’0 with 33-inch inseam. I have tried all the calculators and charts. I am between sizes (56-58). I am looking at the allez Sprint, gaint defy, tarmac sl4 expert, trek domane 6.9, venge elite. None of the bike shops near me have these models. I would appreciate the help.
Hi Justin, I recommend going for the larger frame and then bike fitting it to make sure it fits your body proportions perfectly. Alternately, when you decide which bike you want to get, contact the company’s customer support and ask what they recommend. That can be quite helpful.
Hi Jeff!
I am writing because I am trying to decide between a small and a medium frame for a hybrid bike (more towards the cruiser end of things and less towards the mountain). Diamondbacks are my favorite bikes. I also like the Electra Townies (but they are too heavy!) . I am going car free so I will be using this bike all the time EVERY DAY! I will often be pulling a bike trailer behind it (approx 20 lb trailer) SO I do not want the bike any heavier than it has to be.
I am 165.1 CM tall. Leg inseam of 73.66 CM; Arms from shoulder to wrist 54 CM; Wrist to middle finger 18 CM;
I struggle with shoulder pain…have tried recumbents since my Dad has one and he let me try and I very much disliked being that low to the ground and hard to see in traffic. I also found the bikes hard to balance for some reason (seems like it would be easier) but I would not feel safe in a recumbent anyway as I am moving to Florence, OR soon and will have to deal with the HWY 101 and lots of tourist traffic.
I do not like to hang over a bike in anyway (why I don’t do mountain bikes) and dislike feeling large in comparison to the frame yet I do not want to injure myself by getting a bike that is too small. My usual weight is 160 lbs even when in good shape (which I am not in currently unfortunately). I am not much above that but need to get in better shape, which I hope to do by biking everywhere, hiking and swimming (swimming relieves a lot of pain for me and I have an excellent wetsuit for the 48 degree water there). The pain I have now in my back and shoulders is why I have gained some weight and have gotten out of shape. I am 41 years old and have been an enthusiastic rider of bikes and of the car free lifestyle for many years until bursitis hit (Shoulder not currently severe). I am hoping that, while painful, losing weight through exercising more might bring me some relief. I truly wish I could use a recumbent bike. My athlete weight is 145 so I am rather stocky for a female I guess. Does weight affect bike choices too…maybe get one with suspension? Those have always seemed a lot more comfortable.
Do you recommend the 16 inch frame or a smaller one for a Hybrid? Do you think a woman specific bike would be helpful for me? Also what is the most inoffensive upright bike brand/make for people with mild to moderate chronic pain? I am trying to not get old before my time. This back pain started for me at age 16 (undiagnosed mild sciatica and sports injuries). I can no longer run or compete in sports but I would like to keep moving. The doctor has cleared me for exercise after checking my joints and doing some x rays.
Thanks Jeff! I am sorry about all the details. I need to buy a bike soon and only have three weeks to do it before I give up the car by the end of the month.
Hi Susanne, it’s fantastic that you want to get back on the bike and ditch the car. I’m happy to try and help. Considering your history with shoulder pain, I’d recommend going for a cruiser as the weight distribution will be more toward the back of your body thanks to the upright riding position. Getting one with front suspension will definitely help as well since vibrations from the road might agitate your pain.
However, Diamondback, even though a remarkable company, does not have any cruisers in their lineup. Electra Townie is a great bike, but you can also consider some sixthreezero models and Schwinn Discover, which checks all of your boxes. I don’t think you need a women-specific bicycle, just one that fits well. I think a 16″ frame could be a good choice for you on a cruiser.
Good luck and happy riding!
Hi Jeff,
It’s great to see someone giving unbiased advice to people. You’re doing a great job. I’m after some advice myself. I used to be a cycling enthusiast and want to get back into it. I’m quite tall 6’4” in height (193 cms). Applying your charts above I need a road\city bike of 62 cm frame size. There’s not any I have come across, the most common ones are 56cm frame size. Is it possible to make slight adjustments to that one to suit my requirement?
Thanks,
BM
Thank you! I’m glad I can help. 🙂
Unfortunately, I don’t think a 56 cm bike could be adjusted to fit your height. There are actually many brands out there that make 60+ cm frames. For example, Specialized is one of them.
Hello I’m a 5’2 1/2” female mountain biker . I want to buy a trek top fuel 9.7. Should I go for small size or special order a xs ?
Hey Maddie, I think the Small frame would fit you just right. 🙂
Hi Jeff; do you do the same measurements if you want to buy a cycle for a child? Considering he is 8 years and still growing. Don’t want to buy another cycle in a years time!
Yolanda
Hi Yolanda, kids’ bicycles are sized according to the wheel size and the age of the child. So you can choose by having those two things in mind. You should take the growing part into consideration, but definitely avoid buying a bike that is too big for your kid. It’s not safe and they would not have as much fun on it. 🙂
My height is 150cm , which size frame snd size wheel is best for mr , can i use 26t tyres and 19 inch frame bicycle ?
Hi Asif, you need a 14″ frame and either 26″ or even 24″ wheels. A 19″ frame bicycle would be far too large for you.
Thanks for the helpful article. I have long legs and short arms – the Competitive Cyclist fit guide is suggesting a 58cm frame with a top tube of 53.6cm max. There don’t seem to be many road bikes that fit these criteria. Any suggestions?
Exactly, those dimensions are hard to come by. However, you can easily tweak the geometry by playing with the saddle’s fore/aft position and changing the stem to get the correct size.
Hi,
I am a male with height 172 cm and inseam 82cm. My friend has decided to sell his Fuji Hybrid bike having frame size 19″. Will it be suitable for me?
TIA
Hi Feroz, knowing the exact model would definitely help me give you a more precise answer. With that in mind, according to Fuji’s size charts, I’d say a 19″ frame is too large for you. But I recommend borrowing the bike from your friend and riding it for a couple of days to see how it feels.
My height is 170 cm and I plan on buying mtb. What is the right size for me?
I recommend getting a 17″ frame.
I am 5.11 1/2 ft but not 6 ft. I’m going to buy MTB Hybrid electric cycle hence I should go with 21inch frame, 27.5 tyre size. Please let me know if i calculated right. Please also let me know what size of bike should i go for fast tire / mountaineering bike ??
I’d actually go for a 20″ frame considering you are slightly shorter than 6 ft. However, depending on the manufacturer and the geometry of the bike you choose, the perfect frame size could be different. The same goes for other types of mountain bikes. Happy riding 🙂
Hi Jeff
Can you please recommend me which wheel size I should get.
I am 5.8 foot tall and I am planning to get 17.5 inches frame size
But I am confused with the wheel size
Btw it’s a MTB
A 27.5″ wheel size would be a good choice. There are plenty of mountain bikes to choose from with 27.5″ wheels, so you’ll have an easy time finding the perfect one.
Hello,
My Height is 173 cm and inseam 80 cm , is small frame (S) with 29er wheel good for me?
Hi Zaitoun, a Medium size (17″-18″) frame would be a better choice for your measurements.
Hi, i am 165cm and 73 cm inseam, looking for fit roadbike. according to specialized chart, i am inbetween 49 or 52 size.
And find another chart, height 165 cm fit to size 51,. But inseam 73 cm fit to size 49.
So compuse.. lol.
Which one i should take? Thanks
Hi Eriek, if you’re planning to buy a Specialized bike, then make a decision based on the info in their charts. I recommend a 51 cm frame for your measurements.
I am 5’0 height what size of bike do I need ?
Hi Eriegen, you forgot to mention what type of bike you’re planning to get. If you want a mountain bike, then you should go for a 14″ frame. If you’re looking for a road or a hybrid bicycle, then aim for a 48cm frame.
Hello there, my daughter’s in seam is 32 and her height is 64 inches. What size tyres and frame on a mongoose bike. How to tell if its mountain or city or road on the bike itself.
Hi Reisha, a 26″-wheel bike with the smallest frame should fit your daughter well when it comes to Mongoose bikes. To learn more about different types of bikes, I recommend checking out this complete guide. 🙂
Hey! I’m looking at buying a Trek Fuel Ex 9.7. I’m 5′ 3.5″ and am inbetween a Small and Medium frame. Since I’m a beginner, I was thinking of going for the smaller size.
Size small on this model offers the option of 29″ or 27.5″ (2.6) wheels.. which option do you think I should take? (Wheel size option only available on Small frames. Xs is only 27.5 while M comes only in 29″)
Hey Megha, considering your height, I’d go for a 27.5″ model. Size S seems to be a good choice as well. Enjoy your new bike! 🙂
Hi,
I’m 5’8”-5’9” with a long torso. My inseam is
I went to a local bike shop and they told me I should get a 51” Cannondale. Does that seem small for me?
Hi Kevin, considering you wanted to write “51 cm,” yes, that does seem too small for your height. However, you forgot to write down your inseam length, which would help choose the right size. Give the bike a try since your shopping at a LBS and see how it feels.
Hi Jeff,
Thank you so much for putting together such comprehensive guide!
I am particularly interested in the Retrospec Motley hybrid bike. I can’t find anywhere in their website what the standover height is. I am a 5’7” male (29” leg inseam), would you recommend the S (16 in) or M (18 in) size? I figured you would have much more experience with sizing and maybe even knew about this particular brand.
Thanks!
Hi Javier, the standover height for the S frame (16″) is 29.5″, so that’s the one I would go for if I were you.
Hey jeff!. I’m prolly 187 cm in height and weight 65kg. What size will fit me and what kind of bike should i go for if my purpose is just to commute to gym and back besides leisure riding in weekends?. TIA!
I believe a hybrid bike would meet your needs well. As far as size goes, a 58cm/18″ frame should fit you well.
I am totally new to riding! I am a female Height 5′ 3″ or 160cm. Wt 131.6 or 59.6kg. Our small town in North Carolina has a 17 mile trail. However, I am preferring a mtn bike for the tire size (makes me feel safer as a beginner). What size bike should I ride. I currently have a 24in mtn bike. Thank you for your VERY informative site!!!
Hi Andrea, you can try a 16″ frame with 26″ wheels, I think it should fit you well.
hi, i am looking for help sizing giant road bike. i want o buy online but dont have a place nearby that carries them. the confusing part is that they list only sizes like L and XL. it seem i could fit both.
i am 6’2″ and 34″ and i am not sure which size to go with.
below is the link to the bike in question
https://www.giant-bicycles.com/us/defy-advanced-1
thanks for any advice
brano
Hi Brano, I’d go for the L-sized model considering the information you provided. Happy riding!
Im 5-11 and i ride a size 59 track bike is that to big for me ? What do you think
Hi Octavio, according to most charts, your ideal frame size is 56 cm, considering that you have an average inseam length for your height — 31″ to 34″. So, I’d say you need to downsize a bit.
Hey Jeff, I am 5’9.5″ with a 32″ inseam and a +3.5″ ape index. I tested out a Trek Marlin 7 18.5″ frame and an Trek xcaliber 7 21.5″ frame. I feel like I am between the two sizes due to my longer arms. They are both comfortable. The xcaliber is only $99 more, so I went with that but not sure if it is going to be too big on the trails. What do you think?
Hey Anthony, 21.5″ does sound like too big for your measurements. Have you already tried it out on the trails? If you have and it feels goods, and you’re only riding recreationally, then it shouldn’t be a problem. If you feel any pains and aches or a drop in performance, consider changing it.
Hi I’m struggling in the right city bike (type with a basket) for my daughter, she’s 10 & measurements are inside leg 66cm, height 55”. I was thinking a 26” wheel & 16” frame, is that right?
Thanks
My opinion is that that might be too big for her. However, kids grow fast at that age, so she might be tall enough in a year. At least try getting a smaller frame, 14″ would be perfect.
Hai..what size for rb height 168cm inseem 74.5cm
Hi Arie, a 53/54cm frame should fit you well with those measurements.
Hi ! I’m 166 height 68 kg what size I must chose for road bike ?
Hey Christoforos, according to those measurements, a 53cm frame should fit you well. 🙂
Hi jeff,im 5’11 height,i have large tallboy 3 was good for me,my concern is just bought a xl megatower,dont you this xl is right for me??
According to the size charts on Santa Cruz’s website, your ideal frame size is L. So yeah, I think XL could be too big for you.
Hi Jeff my wifes height is 5 feet and leg inseam is 71 cm. planning to get a Giant Momentum ineed latte 2019, 26 inch wheel size and frame is 16inch. Will it be good for her?
And I bought a Bianchi 27 inch wheel size with a 43 cm (16.9 inch) frame for myself. Im 5feet 10.5 inch tall. Is it ok?
Waiting for your feedback.
Thanks
Faheem
Hi Faheem, both of those sizes sound good for your measurements. Hope you’ll have fun riding together! 🙂
Jeff, I am 5′ 10″ with a 30″ inseam… ideal, 54″ or 56″? Randall
Hi Randall, assuming you’re asking about a road bike and referring to centimeters, I’d recommend a 56 cm frame. Happy riding 🙂
Hi Jeff,
I am confused on which Pinarello Dogma F12 size to buy my hight is 178 cm, inseam is 83cm & arms length 56cm, please advise?
Hi Ayoub, judging by Pinarello’s charts, I’d recommend going for a 53 cm frame. 🙂
Hi Jeff
Thanks for all your answers here and work
I bought the ebike kit of 26” wheel to convert the (future bike) to an ebike I’m 30 years old 172cm high and 85kg my weight and I’m confused about the size of mtb to get my size normally and after a lot of (googling) I found out that the wheel of 26” can fit also 27.5” frame is that right and What’s the size you think it would fit me !?
Many thanks again
Aws
Hi Aws, a 16″ frame should fit you well. Regarding your wheel size question—yes, you can fit a 26″ wheel on a 27.5″ frame, but note that that will change the geometry of the bike.
i’m 165cm tall., i want to buy a road bike pinarello FPuno online, available size is 44 is that ok? or is it too small?, considering adjusting saddle and stem
A 44 cm frame seems to be too small for you. 50 cm seems to be the ideal size according to Pinarello FP Uno size charts.
I am 6.2″ male. Looking to buy a hybrid cycle of frame size 18.5″ and 700C wheel.
Will it be a good choice?
Yes, Mohit, that size should fit you well. Happy riding! 🙂
Hello sir…i am still confused about the mountain frame size (29er) that is suitable for me. My height is 165.7 cm and leg inseam is 77cm.
Hi Larry, a 16″ frame should fit you well. Enjoy riding. 🙂
The frame size should be based on, what Colnago call: Effective Seat Tube Length.
This is the distance from the BB to the intersection of the seat tube and a horizontal line going from the head tube backwards.
This is most applicable to frames with sloping top tubes
Good remark, Peter. The effective seat tube length is quite important, but the seat tube should be considered as well.
6’3 man 34″ Jean size for length. What size bike should i get? Just want something simple for additional exercise at night.
If you just want a bike for recreation and exercise, you’re probably looking at hybrid bikes. In that case, an 18″/58cm or a 19″/60cm bike would be the best choice for you.
Hi..I am 6ft tall. 51cm size MTB suitable for me?
Hi Rupesh, an 18/19″ frame would be the best choice for your height. 🙂
I am 6′ 1″ with a 33″ inseam, what size road bike do you recommend? I feel like I am in between sizes on many of the online charts.
Hi Bob, you should try with a 58cm frame. According to most charts, that’s the right size for you.
Hi: I’m 57 and never road a bike before. I’m 5’4″ and temporarily weigh about 233 lbs…. And would like to know what’s a road bike, and what size would be good for me.
Hi Susan, props on choosing to begin cycling. It’s never too late! 🙂
A road bike is a bicycle with narrow tires and drop bars, most suitable for smooth roads and high speeds. If you choose to buy a road bike, the best size to go with would be 52cm. Enjoy!
Thanks for the excellent information on frame size. Running through all your calculations and tables – I’m male, just under 5’8, with a 30.5 inside leg. Ideally I would need a 54cm frame, but the bike I want to buy manufactures frames at 53cm or 56cm. unfortunately I cannot try this bike! Would you suggest the smaller frame? Thanks again.
Hi Ruben, I would not suggest it with certainty, but it could definitely work out well for you. If it proves to be small, you can fit a bigger stem and pull the saddle backwards to compensate a bit. Good luck!
Firstly, thank you Jeff for your very helpful guide and also all your responses to questions. I am 198cm with a 36 inch inseam and looking for a road bike to ride to uni. What size frame should I look for? And if it’s very hard to find good value bikes for this frame is it possible to compensate for a smaller frame, with larger wheels for example?
Hi Scott, you should look for a 63 cm frame, ideally. There’s a pretty decent choice of bikes with frames that big, so I don’t think you’ll have any problems. Bigger wheels don’t really work for road bikes, 700c is the only option. 🙂
Hi Jeff
I’m looking to a purchase cannondale bad boy and I am torn between small and medium. I am 5”7 female, can you please advise frame size. 17” frame or 18” perhaps??
Hi Sam, for your height, according to the Cannondale charts, medium should be the better choice. 🙂
Hi Jeff,
Does the top frame bar from the seat to handlebars, come into play when properly sizing? I have seen as much as 2-3 inches difference between several similiar bikes? Do you adjust the handlebar height for comfort or do you take seat height into consideration for proper sizing? I am 5’10” with an inseam of 30″.
Hi Rick, not sure if you are talking about top tube length or the drop between the saddle and the handlebars. Both come into play when properly sizing. When it comes to length, you can adjust it by using a shorter/longer stem or adjusting the fore/aft position of the saddle. When it comes to the drop, you can raise the handlebars a bit by using spacers, but not by much. The difference in the drop is normal, as some bikes have a more aggressive (racing) geometry, whereas others have a more comfortable setup. Cheers.
Hi, I’m a 6 feet tall man.iam planning to buy MTB.
which size suits me ?
Hi Rupesh, a 19″ frame would suit you best. Enjoy your new bike!
Hi,
I am a 5′-3″ woman with a 30″ inseam, longer legs, short torso, long arms, trying to buy a triathlon bike, which size would fit me best?
Hi Clara, considering that you have a short torso and longer legs, you should be on the shorter spectrum for your height. Perhaps a 50-51 cm frame would be good for you. 🙂
Hello Jeff,
I am 172cm and my leg inseam is 83.82cm, so what size should i look for aero road bike and mtb?
Hi Sheraz, go for a 54-55 cm road bike and a 16/17″ mountain bike. 🙂
Hi
My name is Varun and I got a Cannondale Quick 7 (2019 model)yesterday with a large frame size. but I am still confused whether I bought the right size or I should have gone for extra large size ?
my height is 6 feel.
Hi Varun, your height is right in-between the two sizes. Both could work, depending on the type of your build. If you feel good riding it, then you made a good choice. 🙂
Hi Jeff,
Would like to know the role tires play here.
Would there be difference with 29er and 26, both M frame.
I am almost 6ft. Getting a good deal on Fuji Nevada 1.1 29er with M frame.
What do you think?
Thanks for responding.
Hi Rishi, bigger wheels can make the bike feel bigger by increasing the standover clearance. However, the geometry of the bike will not change. A small frame will be small even with 29″ wheels. M frame for your size sounds like awfully small. You need at least L or XL.
Jeff,
Thank you for the great info. Im 5’11, 175 pounds. Inseam 33-34″. I was fitted for a Cannondale Topstone gravel bike in medium (56). I feel cramped in the torso and legs with the reach being good. I’m thinking about swapping for a large (58). Does this sound reasonable?
Mark
Hi Mark, sure, if you’re not feeling good riding it, definitely make some changes. You can adjust the reach on the larger frame by swapping the stem, if it proves to be too large. 🙂
Hi, looking at getting a voodoo bantu MB, I’m 5’8, my inside leg is 29″. What frame size do you recommend please? Thanks
Hello, I believe an 18″ frame would be good for you. 🙂
This was very helpful. I’m a female who is 5’3 but my inseam is 33.5in. I’m clearly all legs. What size mountain bike or hybrid bike would you recommend?
Hi Christine, glad you found the article helpful. 🙂 I’d go for a 15″ frame if I were you.
I grew up riding my father’s old bike, which was really well built and once adjusting the seat etc. I never thought twice about it. Finally when I got into riding and racing more seriously I realized maybe these hills are so excruciating for some reason other than fitness. My father’s about 20 cm shorter and his legs even shorter than that proportionally. I’m about 198 cm and a lot of it’s in the legs – the inseam is 93 cm. The difference for a long time rider when I finally got a suitable bike – a long and difficult process haha – has been astonishing. Thanks for the article.
You’re welcome, Bill. I’m happy you found it valuable. That’s a great observation on your side as well, getting the right fit makes all the difference, especially if you’re riding long distances. I’m sure there are many people out there who are familiar with your experience, including me. 🙂
Hi Jeff,
Thanks for all the charts and various ways to measure. A question though…
Like me, my son is “long-waisted and short-legged”. So, even though he is ~ 5/10″, his inseam is ~24″. We are shopping for an e-bike, to assist with his college commute. He hasn’t ridden a bike in many years, so we are hoping for a very positive experience – starting with a good “fit”. Any observations would be welcome. Thanks. (Trying to go via ebay, so we can spread out the payments with a paypal credit situation. That’s why we’re trying to skip going to shops).
Regards,
Carole
Hi Carole, long-waisted with short legs is much easier to fit than the other way around. You should just choose the standard bike size relative to your son’s height and adjust the saddle height as needed. Since your son is 5’10”, you should go for a 17/18″ or a 54/55cm frame. Good luck! 🙂
Hi i am 152cm tall women
What size of cycle will be good for me if i go with wheel size??
Thanks
Hi Azra, you should go for a 26″ bike with a frame size of 14″/48cm.
I planning buy an Aero bike.I’m 5feet 9 inches.
Hi Harjeet, if you’re wondering about the size, you should go for 54-56cm. Happy riding!
Hi there,? I’m only 5ft in height and looking for bike ? I think my legs length is 29- 30 I think .
My hubby got my lovely pink Trax bike but unfortunately my tiptoes just touch floor . Gutted because I think the frame is to big, please cud u help ? Many thank yous
Hey Lisa, when you’re sitting flat on the saddle, your tip toes should, in fact, barely be able to touch the ground. However, if your saddle needs to be in the lowest position for that to happen, you should probably get a smaller size. For you, the ideal size would be 14″. 🙂
I am 6′ 3″ with an inseam of 34″ I want to buy a Trek Domane (geometry chart here: https://www.dropbox.com/s/475wrqw8n9elsz3/Geometry.png?dl=0)
It seems to me that since my inseam is short for my height, my upper body is therefore long and I would need a relatively large frame (leading me to think I need a 62cm). Would you agree?
Hi Cliff, I think a 62cm frame would be an overkill for your height, even though your torso might be proportionally bigger. A smaller frame would be better in my opinion.
Hi Jeff I am 6 feet tall and looking for a city bike what size should I buy L,XL
Please mention frame size and wheel size.thanks a lot in advance
Hey Tushar, the ideal city bike for you should have 700c wheels and a 17″/56cm frame. Enjoy your rides!
Hi, my husband is trying to find the correct size after ordering 2 different bike styles.
He is 6’2” and weighs 230 lbs. We are thinking he wants a mountain bike.
What size should we purchase?
Hi Beth, your husband should look at bikes with an 18″ or 19″ frame if he is planning to buy a mountain bike. 🙂
I have the hardest time fitting a bike. I am a woman, 5’11’ and have extra-extra long legs with a short torso. My inseam is 33″. My waist is short. Problem I face is that the seat has to be high and then the handle bars are too far away so basically I am bent forward way too much and this hurts my neck. I want a urban/city bike but NOT super low or high handles. I see so many bikes where the seat is horizontally at the same height as the handle bars and I don’t like this. How can I choose the right fit?
Hey Cynthia, people with long legs/short torso generally have the hardest time to find a proper bike size. Ideally, you should choose your bike size according to your torso length and not your overall height as you can easily raise the saddle. If you do not care too much about the appearance, you should consider some comfort bikes. They usually have saddles lower than usual, so it will give you some room for adjustment.
What about the handle bar height? I have the right size bike according to the chart, saddle is adjusted for leg length and comfortable, but I get a lot of pressure on heels of my hands while riding. Wondering if the handle bar is to low or needs adjusting?
Hey Connie, if possible, try raising the height of the handlebar. If not, perhaps you need to push the saddle back/forward a bit and see if that changes anything for you.
Im ten, and will a 26″ fit me? im 4ft 7 in. Or will 20″ and 24″ have to do?
Hi Kira, a 24″ bike would be a better fit for your height I believe. However, kids your age grow fast, so depending on how fast you grow, you might be ready for a bike with 26″ wheels soon as well.
Hi Jeff!
You wrote a very informative article. It will help me to write my next article about standard bike choosing.
Thanks,
Bungosana
I am totally confused by this. I am in between and don’t know what to do. Every measure is different, it ranges from 55 to 58. I got all the different results from bunch of websites. I am 183cm in height and my inseam is 83cm. I think the 56 it’s the right measurement for me because that is the measurement I got the most times but I’m still confused and don’t know what to do.
I agree with you, a 56cm frame would be best for your measurements. If possible, try the bike and see how it fits. 🙂
Nothing about any of these methods is useful – all of it is antiquated and oversimplified information. Even as a bike shop manager and professional fitter, I appreciate the sentiment that some people want to save money by cutting out the middle man, but the reality is that these charts and methods are incredibly generalized and do not take into account the rider’s personal medical history, flexibility, reach (the absolute most important large dimension in bike sizing), or other physical restrictions or attributes, nor does it take into account the completely different geometry between subcategories of road bike and mountain bike, and the even more minute differences between bikes of the same subcategory from brand to brand. I, for example, have very low hip restriction, low flexibility in my lower back, and a short reach compared to my body dimensions (6’0″ with a 32in/81cm inseam). On most road bikes except for endurance geometry bikes, I either have to ride a 54cm frame with the saddle slid obnoxiously far back (2+ centimeters aft) for proper KOPS and deal with awful toe overlap and the near inability to get in the drops unless I sub the stem for (typically) the stock length at a greater positive angle OR ride a 56 centimeter frame to solve the issue of saddle-to-bar drop being too great for my flexibility with an obnoxiously short stem (70-80mm), which ruins handling in corners and at speed. None of this is even remotely uncommon – roughly 40 percent of the cyclists I fit in the course of a month experience similar peculiarities in their body dimensions, range of motion, flexibility, etc. My point is, for anyone reading this, do not take these methods as gospel. Bike fitting is a very individualized process, and I have yet to find a chart that takes any of these things into account – you wouldn’t order your clothes from a chart that said your height dictates you wear somewhere between a 30 and 34 inch inseam in pants and sticks you with a large shirt even if you need a medium because you have short torso and slender build, would you? No, that’s ridiculous. Don’t do the same with your bikes. Yes, some bike shops are out to squeeze you for money, but most consumers are smart enough to shop consciously and pick the most honest and reputable shop. Believe it or not, some of us know what we’re doing and want you to enjoy your cycling experience, even if it means price matching with similarly spec’d online bikes to ensure you get a proper fit. Cheers.
Thank you for your comment Matthew. I think it’s incredibly useful and valuable for anyone out there thinking about getting the right fit. I absolutely agree with you that nothing beats a professional bike fit.
Still, I believe that the charts on this page are incredibly valuable for people who wish to save money by purchasing a bike online or simply do not have access to well-equipped local bike shops in their area.
As I have mentioned a couple of times before, every person is different, but we’re also very similar since our bodies follow general patterns, which is what these charts are based on.
Cheers
Hi, sorry I feel I’m late to the party but….
I’m a 37 year old 5 foot 3 inch woman, who has, at most, been on a bicycle 3 times in the last 2 decades. I’m not searching for a bike and need some help with the size. Most bikes I find have a 28 inch tire, but these are typically too tall for me when using actual measurements. I’ve found a bike with an 81 inch seat height (at lowest), and unfortunately I can’t test it out since it’s online.
My question: what’s the ideal size for me?
Hi, Kate. You can’t be late to a party that never ends. 🙂
I assume you’re thinking about buying a hybrid or a city bike. If that’s the case, the ideal size for you would be 15″/52cm.
Hi jeff, I have the opportunity to buy a whyte cornwall road bike with a 57 cm frame size at a bargain price. I am 6’3″1/4 with a 35 inch inseam and a negative ape index. Do you think this bike could work for me?
Kind regards, Dave.
Hi David,
57cm is one size smaller than ideal for you. However, since you have a negative ape index and your reach is smaller, that deal could still work for you after some additional tweaks.
Hi Jeff, I am bearly 5 feet women and petite, looking for a bike, but nothing heavy and want to be able to reach the ground. What size would fit me?
Thank you.
Hi Fatma,
It depends on which type of bike you’re planning to get. Overall, you should look for a bike with 26″ wheels and a step-through frame, which will make it a lot easier for you to get on and off. Look for the smallest frame size they have. Most of the time, that’s 13-14″. 🙂
Hi!
Great article! Do you have a review for e-bikes, or pedal-assist bikes somewhere? I am female, and there are so many choices. It would be my first. So far have owned only mtn bikes….
Thank you!
Maria
Hi Maria,
We are just working on an in-depth review of the best e-bikes out there, so stay tuned as it should be finished soon. 🙂
Hi! I recently purchased a Fuji absolute hybrid. 17”. I am 5’5 female My hands feel a bit of pressure when I ride, but otherwise I love it. What is the preferred size for my height? And would I be able to tweek it to relieve the hand pressure? Advice?
Hi Maria,
That’s a beautiful bike. 🙂 According to the size guide on the Fuji website, you should have chosen a 15″ model (S). If you can, you should go to a local bike shop that does basic bike fitting and they’ll help you set it up to suit you better.
Thanks, Jeff!
Hi,
I am a 17 year old, 5’0” girl looking for a bike to ride on the streets of NYC…any suggestions ?
Hi Nerissa,
Look for a hybrid/city/cruiser model, depending on how much you want to ride. Ideally, try finding a bike with 26″ wheels and a 14″ frame.
Hi Jeff,
I am a 5′-9” woman with a 33” inseam and I am looking for a bike that I can use on roads for +-20 – 40 km rides but also for rough gravel roads. I live on an archipelago, salt is also a concern. Don’t want a bike that is too heavy either. Do you have any suggestions re. type of bike and size? Thanks!
Hi Maureen,
You should check out some gravel bikes, seems like that would be the best choice for your needs. We’ve already reviewed some gravel bikes made by Diamondback, which are quite good. A hybrid bike with slightly wider tires would do the job as well, depending on what kind of roads you will ride most.
As for the size, you should look for a 53/54cm (16″/17″) frame. 🙂
Jeff – thanks for the write up. It’s very clear. I’m 6’4″ with a 36/37 CM inseam..so mostly leg. I know “by the book” I should be on a road bike XXL frame ala 62cm and up for seat post measurement. Issue is there is a road bike that I’m really keen on and it only goes to XL @59cm. It an online source (in the UK, I live in the USA) so i cannot try.
From your knowledge, would it be a no-no to go with it? It’s not cheap , so perspective would be great- thanks
*correction * the XL is actually 57CM! not 59
You’re welcome, Mike, glad you found it helpful! 🙂 I think it would be quite risky buying a 57cm frame considering you’re quite a big guy. I would not risk it, more so since you say the bike is costly as well.
Trying a bike before buying it is NOT over rated. . . it is CRITICAL. You would be making a large error in ordering a bike on-line that you have never ridden unless it is a replacement for a bike you are familiar with or you are an experienced cyclist.
Not only is this buying information very wrong, the author completely passes over the fact that a bicycle purchased sight unseen on-line has to be assembled properly and this may require both skill and special tools. If you do get the bike sized properly and then assembled properly – which is not a given – and you don’t like the bike then you are going to be facing a rather big job getting the bike disassembled and repacked in order to return to the warehouse. We are talking hours not minutes.
Do yourselves a big favor. . . go test ride a bunch of bikes. You will find that the glossy on-line pictures and marketing hype are not a great basis on which to choose a bike. You will also be treated to invaluable advise from people that actually do know what they are talking about.
After you have found a bike you really like in a size that is right for you THEN you can shop for the lowest price on-line and have the partially assembled bike delivered to you . . . mess up the assembly. . . put the broken parts in your car. . . go to a bike shop and pay more than you saved to have them repair the bike. . .
Thanks for sharing your opinion on the topic! I agree with you that it’s always better if you can try the bike before you buy it, as I have stated a lot of times before. But, sometimes that is not possible. Some brands only sell their bikes online. In such cases, there are ways in which you can get the right fit most of the times, the best of which we have included in this article. 🙂
Wow! What an informative, straightforward post. This is a keeper!
I have a Marin 29’er Pioneer Trail that I just love. I’ve changed the riding geometry to suit my style. Being in the 70+ age bracket, I raised the handlebar height, made my rear 8-speed Acera Derailleur do what in never was designed to do (that being, easily climb up on a 40 tooth sprocket) and clamp on “L” bar ends.
One thing to note for recreational MTB rides is handlebar width. I found the 26” bars so narrow I felt unstable. Shoulder width and a little wider is a good rule of thumb.
The only bike I left “stock” is my ‘75 U09 Peugeot that I bought for $75. Simplex shifters (pure junk) and all. She’s still a beauty. I had to replace a failed front Derailleur with a Campy. Hard to find without a bike attached.
Sorry but got off track.
Regardless, great post!!!! Thanks.
Hi Dave, I’m happy that you found the article useful! Thanks for sharing your experience as well 🙂
Hi. I am 5’6″ (167.6cm) and my inseam length is 30″ (76.2cm). For a city bike, I get:
Method 1: height, I get a 16″ bike size. =M
Method 2: inseam 30″ x 0.685 = 20.55″, 52.2 cm.
Method 3: Size chart. For a city bike I choose the third line/range and get 16″/M. This is confusing, because my legs are short for my height, yet I’m toward the bottom of the height range on that line, yet toward the top of the leg length range? The size confirms method 1, height only.
Method 3b16/30: Inseam (76cm) only chart gives 15-16″.
Method 4: Amazon: By height I’m at the top of S/15″ range, by inseam I’m square middle of 17″. (Again, why am I bigger by leg length)
I guess the consensus is a 16″ bike size, but it looks to me like the multiplier number for inseam/leg length number is off, although I’ve seen similar numbers elsewhere. A 30″ inseam is small in pants sizes, but comes out in a large bike size.
Hey Michael,
Yes, a 16″ bike would be the best choice for you. As for your confusion regarding the inseam length, humans come in different proportions. Some have longer legs, others have longer torsos. This discrepancy can usually be amended by fidgeting with the saddle height.
Hello I’m 6 ft 6 what size bike do I need …mountain bike
Hi Brett, get the biggest one they have. That’s usually a 22/23″ frame size. 🙂
Hi Jeff, thanks for the useful article. I have bought Vitus escrape VR (650b) frame size L, but now I have doubt that I choose the right frame size. My height is 179cm and inside leg is 85cm, what do you think? Maybe is best choose for me M size?
Hi Denis,
I think you made the right choice. The L size suits your inseam length much better than the M size. You’re right in-between the two sizes and it’s always better to choose the bigger one. Enjoy your new purchase! 🙂
Hi Jeff!
I’m an adult standing at 5’2″ (I know, short lol) who hasn’t learned how to ride a bike but I’m trying to pick it up. I just need a good beginner bike to practice where I can set my feet on the ground for balancing purposes. What size bike should I go for?
Hey Ken,
It’s never too late to start enjoying cycling! It depends on which bike you choose, but I’d recommend looking at 15″ bikes. Have fun! 🙂
Won a bike, yay me! But I think the frame is too large. My Specialized Dolce Elite women’s bike sticker says “54” so I got a Cannondale SuperSix Evo 105 frame size 54 but it just feels much bigger. Am I crazy? I’m a 5’5″ women. Wondering if I should try to switch it out for a 52 or even a 50. Road bike. Thanks!
Hey Katrina, congrats on your prize!
According to Cannondale’s bike size charts that I managed to find online, you should go for a 50cm frame. According to Specialized’s size charts, the 54cm Dolce Elite, should also be too big for you. But since you feel it fits you well, maybe a 52cm Cannondale SuperSix Evo will fit fine as well. It’s best to try both sizes and see what feels better. 🙂
Hi,Jeff
I would appreciate your thought on the following – I am a “reborn” cycling lover; for the past two years I have been riding my old 26′ wheel bike. I intend to buy a new bike this summer and I have been advised multiple times to focus onto 27.5′ wheels the next time I choose a bike. I am only 159cm high (or short 🙂 ) female, and I’m not sure I should actually switch to a larger wheel size.ocasuonally,I feel like I would love a bigger wheel but, since I rarely ever ride my bike on flat ground and often struggle with hills and uneven surfaces ,I am a bit afraid because manipulating a bike with smaller wheels just seems more logical for a short person like me.
Do you have any thoughts on that ?
Btw, i ride only MTB
Thank you I’m advance
Hi Maya,
It all depends on the bike you choose and the size of the frame. 27.5″ wheels will not necessarily create a problem for you if the standover clearance is not too high for you. These wheels are not hard to get used to when switching from 26″ ones, but they offer a lot of advantages on the trail. Since you say you mostly ride off-road, I think that would be a good move, as long as the bike still fits good.
Hi Jeff, I am 5’4″. I am getting into cycling and want to buy a used road bike. There are not many options for a S frame bike. Would it be a stretch if I used a M frame road bike?
It depends on the manufacturer and the model. It could work out, but it could end up being too large as well. You should find out the geometry of the bike you want to buy and try to figure out if you could get it closer to an S frame by using a smaller stem and adjusting the saddle.
Hi Jeff I’m new to biking at 37 years old, and I bought a 29″ Schwinn Knowles mountain bike. so far ive been happy riding but after some research im worried the frame size is too small for me; im 6’6 and measuring the frame its a 21″. Do you think this will continue to work for me? Thank you.
Hi Josh,
Ideally, you should have bought a larger frame. However, if you continue riding it and experience no major performance or health issues, I don’t see why it won’t work. 🙂
There is a new 2013 model Kona Kahuna mountain bike that’s ~27 pounds that looks to be a great deal online at $510, being 18″ with 29″ tires.
I wrote the sales person, telling him I’m 5’7″ with 30.5″ inseam, and he said it’s the perfect size for me (of course, I’ve not sat on it and know of no local bike shops that sell Konas).
I was skeptical until I read your comments here to “Shell on May 1, 2019 at 10:36 pm,” and she is 5’4″ with a 30.5″ inseam and you suggested perhaps a Trek 17.5″ with 29″ tires would be an ok fit. So this sounds similar to my situation.. hmm..
I don’t know if Kona & Trek have similar geometry, so, I’m hoping you can offer some advice. $510 for a 27 pounder having 29″ tires seems a great price.
Hi Johnn,
Looking at Kona’s geometry, I believe a 17″ frame would fit you better. There’s a chance that 18″ could work as well, but it’s a risk.
Hi Jeff,
My height is between 5feet 8inch to 5feet 9inch. I am from India and planning to buy a mountain bike. Which size will be suitable for me either M 17″ or L 19″. I am planning to buy BTWIN ROCKRIDER 500 model from my friend having M frame size. Could you please let me know whether M size would be fine as I am beginner and can’t differentiate.
Yes, a 17″ frame should fit you well. Enjoy your new bike! 🙂
stupidest charts I’ve ever seen… Rider’s hight is in centimeters, frame size is in inches… DUMBASSES.
The frame size is always shown in inches. The riders’ height is shown both in inches and in centimeters.
Hi I m looking to buy a road bike, I m 1m73cm what frame I m looking for? Thanks
Hi Florin, you should look for a bike with a 54cm frame. 🙂
Hello! My son is almost 15, 5’11” and weighs 190lbs., he wants a BMX bike for his birthday but I don’t know what size to get. Can you please help me?
Hi Becky, your son needs a BMX bike with 20″ wheels. Best to take him with you and let him choose which one fits him best. 🙂
Hello my son is 5 foot 10 inches tall and is almost 15 years old and growing fast. He has 29-30 inch inseam. He needs another bike. I found a nice road/hybrid bike that is 21″ frame. Would this be a good size for him? Would it fit him now with the seat down and when he grows he could raise the seat?
That’s definitely too big for him, James. I recommend looking for an 18/19″ frame and upgrading when and if he grows much taller.
Hi Jeff,
Very informative. Thank you.
I have my eye on a specific bike, but the frame might be too large. I am 184cm in length, and said mountain bike is a XL. Could I get by by moving seatpost around a bit?
Hi Jacques, can you share what bike it is? It would help me to answer your question more precisely. XL means a different thing from one manufacturer to another. But, generally, an XL bike should fit your height.
I’m looking to buy 2 bikes one for my wife and I. Our measurements
Me
5’10 with 31″ inseam (180lb)
Wife
4″11 with 25″ inseam (125lb)
Wanting to buy hybrid bikes. Can you help on on sizes?
Hi Jo, you should go for a 17″ frame, whereas your wife should go for a 14″ frame, in my opinion, and according to most bike size charts. Enjoy riding! 🙂
I need help too, as I also fall right in the middle. Was it a good idea to go medium or go small for me?
Trek FX3
I am short male, 5′ 5.4″
Inseam is 29 to floor.
I was able to try both small and medium of these bikes.
I did indeed feel a difference in the reach; obviously reaching farther with the medium.
But, since I don’t really “ride” yet, I don’t know any better.
Your advice?
Thanks for all you do here,
Brent
Hi Brent, I always advise choosing the larger size when you are in-between two sizes. So, I recommend choosing Medium in your case. 🙂
Hi Jeff,
I’m looking at purchasing (online) a 2018 Diamondback Lux 3 mountain bike in a size small. My husband is concerned that it might be too small. I’m 5’3 with a 27″ inseam. Could I please get your input. Thanks.
Hey Laura, that’s the right size for you, according to Diamondback’s sizing charts. You should go for the Small size with Lux 3. Enjoy your new bike!
Hi Jeff I have purchased a road bike and I don’t even know what size is the bike I think it’s around 55-56” I’m 5-10” what would be the right size for?me thanks
Hey Viktor, the right size for you is 56-58cm. Cheers 🙂
Sorry, I’m a little confused about the bike sizing. My wife is 4’11”
She thinks she has to have a 24″ bike. I don’t think this is true as long as the seat adjusts low enough. What is your expert opinion? It’s also hard to find a 24″ that is not kid themed.
Hey Rick, your wife definitely does not need to get a 24″ bike. A 26″ bike with a step-through frame would be fine. Just make sure to get the smallest size. 🙂
Hi! I am a 5’5 twelve-year-old, and my old bike is too small for me. I know that the ideal size for me is a medium, but I want to keep this bike for a long time. What should I do?
Hey Giana, you can get a one size larger bike than what you need right now if you think that you will grow into it soon. I’d advise trying it before purchasing and investing in a shorter stem to make it more comfortable in the meantime.
Hey jeff, I’m 6’2″ living in India , I saw a mountain bike on internet with 26T tyres and 19 inches frame size. Will it suit me good or if not any suggestions please
That sounds to be about the right size for you. You can always adjust the saddle position and the stem if need be. 🙂
My son is 5’1” and is 10. What size would you think would be best. I was thinking 24”? Do you think it would give him enough room to grow or should i go up?
Hi Alicia, I think you can go for a 26″ bike since boys start growing rapidly around that age. Make sure to give your son a chance to try out the bike if possible and see whether he feels comfortable riding it. 🙂
Hi Jeff. Hoping you can help to clarify. I have a growing son currently at 6’5″. Because he is still growing we do not want to spend a lot of money on a bike yet. Found one on Craigslist Schwinn 700c Mens adult. Sticker says measures 70L x 25.5w x 43h. And yet I still cannot determine if that is a 23 or 25, XL or TALL” frame which is what we have been told he needs. Can you shed any light here for my pea brain?
Hi Sarah, it depends on what these measures mean. If 70L is the effective length of the top tube, I’d say that would be suitable for your son. If possible, contact the seller and ask for more details before purchasing.
Hi Jeff. Appreciate your site and expertise!
I’m male, 174 cm / 78 cm inseam barefoot and I’m about to order Canyon Pathlite 5.0. Their calculator suggest I have to choose size XS, because they think I have rather shorter legs, but I don’t want to fo for XS, because it has 27.5” tires and I really wanted a bike with 29″ ones that are available in Pathlite size S and above. Looking at the geometry of the bike Size S is made for people of my height 168 – 178 CM but my inseam could be an issue. My biggest concern is the standover height of the bike. I currently ride a 17″ bike with 28″ tires and it doesn’t break my balls. But Pathlite Size S is 19″ plus its bigger tires could make a standover height higher than my crotch. Unfortunately, Canyon does not provide the standover height of the bike, even by request. They don’t have such info. If the bike comes taller than my crotch can I compensate wearing trainers with XL soles? Also, can I calculate a standover height of a bike by looking at its other dimensions? What would you suggest going for S or choosing XS which is made for smaller people 158 – 168 CM?
https://www.canyon.com/en-bg/fitness-bikes/allroad-bikes/pathlite/pathlite-5.0/1982.html?dwvar_1982_pv_rahmenfarbe=BK%2FGY&quantity=1
Hey Stoyan, getting an S size is risky, but it might work out. As far as I can see, the seat tube length on the S size is 49cm, which leaves you with around 30cm to spare, but it all depends on how high the bottom bracket is. With a slightly higher sole, I think it might work.
Hi, thanks for the info. I just got a Diverge 61cm. I’m just short of 6″3. Saddle is still fairly high. No discomfort. I guess I’m borderline? Should I have gotten 58? Or does it seem right? Sales said it was my size.
If you have no discomfort, then it must be the right size. According to the charts, you’re spot on. Enjoy your new bike, you made a good choice. 🙂
I am looking toward getting a trek marlin 5 in either a 15.5” or the 17.5” with the 29” wheel. I am a female, 5’4” tall, 30.5” inseam, 125#. The bike guy says I am in between sizes but that i look like i fit better (judging by the bend in my knee) with the 29”, 17.5”. I am used to riding a small, cheap walmart bike so getting on the bigger one has me on my tip toes. He suggested this bike with a shorter stem. Idk what to do. The smaller one feels like it fits better but idk how they are “supposed to” fit. I think the larger one may be just right with smaller stem once i get used to the height difference and feel of a larger bike. What should i do?
According to Trek’s charts, you have both the right height and the right inseam length for the 17.5″ model with 29″ tires. It’s normal that a new bike feels strange at first, it takes some time to get used to the change. With a shorter stem, it should feel much more like your older one. 🙂
Hi Jeff, my 16 y/o daughter has had bike size problems forever. She’s 4’ 9” and weighs 100lbs. I suggested (and sounds like your charts do too) that she purchase a 24” wheel cruiser in the kids dept. She has purchased bikes too big (26” wheel) and always looks like she’s struggling when riding. She wants an adult bike, and loathes the childish looks of the 24” hybrid/cruisers. Do you have any suggestions please? Thanks!
Hi Caryn, have you tried out a MTB model? There are many with 24″ wheels that do not look childish at all. Alternately, you can check out the Sixthreezero cruiser bikes, they have one-size-fits-all frames, so one of their 26″ bikes might fit your daughter well.
Hi Jeff, Thanks for the article.
I’ll a bit confused on one point. I’m 5’10” (177cm) with an inseam of 31″ (79cm). Based on most of the tables it looks like a should get a 17″ frame. But, if I use method 2 based on my inseam I get 79*0.66 = 52cm = 20.5″, which is a huge difference.
Looking at the tables again I think this might be to do with the conversion of frame sizes from cm to inches. Method 3 has two tables for City bikes, one in inches and one in cm. The 5’9″-6′ row has 17″ frame size in the first table and 56-57-58 cm in the second table. But 56cm=22inches!
That’s right Rob, the conversion of frame sizes between centimeters and inches differs. The right size for you would be a 17″/56cm frame. 🙂
Hi Jeff,
I’m pretty short at 4’9” was looking to get a hybrid. I’m just not sure what size, what would you suggest?
Hey Lisa, you might consider getting a bike with 24″ wheels. Alternately, you can get a 26″ bike with the smallest frame size available, but it would be best if you could try it out before buying and see if it fits well.
Hi,
My height is 185.5cm but my inseam is 90cm what size should I go in Cannondale and Merida road bikes.?
In my opinion, a 58cm frame would be a good fit for you. Your leg inseam won’t be a problem, you can lift the saddle to accommodate for it. It would be a bigger problem to get a larger frame and experience back and shoulder issues because of that.
Hi Jeff im looking at purchasing a used Fondriest FT3 1.2 Size 48 Medium.
My height is 1.78 and with no shoes on from floor to inner leg is 83.
Could you please advice if this bike is ok for me
Many thanks
David.
Hi David, according to the charts, you need one size bigger frame than that. It could work with some slight adjustments, but nobody can guarantee that you won’t have problems in the long run.
Hey. My height is 6’3″. I am thinking of getting a vintage Specialized Rockhopper with a 20″ frame. Do you think this will work for me? Also, is it wise to get an old mountain bike and turn it into a hybrid?
Thanks
I believe that is one size larger than what you need. It might work out, but you might experience some issues in the long run. As for the conversion of a mountain bike into a hybrid bike, that sounds like a fun project, I don’t see anything wrong with it. Share the results with us when you’re done. 🙂
Hi Jeff
Hope you can help… if you’re not getting bored of giving size advice?
I’ve just bought a Specialized sirrus x comp carbon. The store insisted medium was the way to go. I’m somewhere between 5’10 and 5’11. They had to order the model into store for me to try. I did and it feels ok. I think. But most guides say 5’6 to 5’9 for medium. If a bike is to small for you what feels wrong? When gripping the handlebars I lean over at about 30 degrees(guess) and there’s a slight flex in my arms. Seats slightly above handlebar height and when I peddle the extension takes me to an athletic position ie not fully extended and definitely not cramped.
Is there an advantage to a size up if you’re in between? My instinct says actually if inbetween then go smaller… theory being why drag extra weight around on a bigger bike? Hmmm overthinking?
Hi Darren, sorry for the late response. Not bored at all, I’m glad to help whenever I can. 🙂
As for your question, according to the charts, you should have gone for the Large frame. However, that means nothing if you’re feeling comfortable when riding. Judging from your explanation, I think you still made the right choice. So, don’t overthink it and enjoy the rides.
Hi Jeff. I’m just a beginner and I want to ride. I want a road bike in particular. I’m 6’4-6’5. What size should i get? And what brand/type of road bike do you suggest? Many thanks.
You should get the biggest frame with most models – 62-63cm.
There are plenty of great bikes online. I’d suggest you start with the best road bikes. And if you need more choices, just move to the Road Bikes section where I’ve covered plenty of different price scales.
Thanks for the great article. I am planning to buy a Trek FX 6 hybrid (https://www.trekbikes.com/us/en_US/bikes/hybrid-bikes/fitness-bikes/fx/fx-sport-6/p/24521/). In a place where I live they do not have it in stock (so I cannot try it), and I am just in between two sizes.
I am 187 cm tall with 87 cm inseam and a negative Ape index.
The manufacturer guideline is:
L (seat tube 50.8 cm or 20”): height 174-187 cm; inseam 82-88 cm
XL (seat tube 55.9 cm or 22”): height 185-197 cm; inseam 87-93 cm.
The negative Ape index implies that I should opt for the smaller size (i.e. L). I guess that I would be fine with both sizes, but I am wondering what are the advantages and disadvantages of having a smaller/larger frame.
I would love to hear your suggestions or comments. Thanks
Hi Amer,
It seems to me that you’re good to go with either L or XL frame. Since you need to choose one, I’d take the L because of the APE index.
Hi,
I am 5ft0in and weight nearly 300lb. I am
Looking to get a bike, but know virtually nothing about them. I hope to use it for riding around just for fun and exercise.
Is there such a thing as a step through fat tire bike?
What size bike do I need?
What do you recommend for me?
Thanks!
Hi,
I’d suggest you choose some mountain or, even better, a hybrid bike. Co-op Cycles bikes, for example, have a lower top tube so it is easier to get on and off the saddle. I haven’t noticed a step-through fat bike. But, if you are choosing a fat bike, I’d suggest going for Diamondback. They have proper fat bikes available.
Final thing I suggest is not to go too cheap, as the cheapest models won’t handle the weight well.
Just make sure to start slowly, so as not to injure yourself.
Hi im a 46 uear old male, im 5’11” and about 205. im looking at buying a felt decree frame in size medium 18″. Is this to small of a frame for me?
Hi Lou,
Yes, the 18“ frame is ideal for you.
I did a mistake trusting to the according tables.
Hi Nikolay,
Sad to hear that. Could you share a little bit more? What bike and model? What are your measurements and how was it wrong (too big, too small)?
Hi jeff,iam 172cm and my inseam 76 and i need a road bike what’s the frame is suitable for me
I’d take the 52cm frame if I were you. But since your height and inseam ratio is quite different, consider the size charts provided by merchants.
Jeff, I’m looking at a Diamondback recoil 29er. I am 6’2″ and an inseam of 32-33. The bikes sizes are M18″ or L20″. I’m worried About going too big. What would you recommend?
Hi Brian,
I’d take the 18“. I agree that the 20“ can be too big for you.
Hi Jeff
I want to buy a mountain bike 26 inch or 27.5 inch and my height is 5 feet and 3 inch and my inseam is 28 inch which frame size should I consider and more comfortable. Thank you Amjed
Hi Amjed,
26“ and 27.5“ are wheel sizes. You want to find a 16“ frame size.
Any different size advice for overweight people looking to lose weight? I’m 5’9″ but weigh over 250Ibs. Inside leg is about 30″. Is a smaller frame with the saddle adjusted higher a better option? Looking for a road bike.
Great idea to lose some weight by cycling! I’ve witnessed many friends getting great results by doing that.
There are no benefits of having a smaller frame with a higher saddle. In most cases, the bigger frame and lower saddle combination is better if I have to choose one.
If you are new to cycling, do not take huge steps at the beginning. I’d suggest you consider a hybrid bike because it has a quite relaxed geometry. On road bikes, you will risk potential injuries.
My name is Nikhil. I am 21. I want a bicycle for daily use of 20 kilometers in city roads and/or on highways. My height is 6’1.5″. My bicycle must be light in weight and maintenance free. What are the specifications my bike should meet?
Hey Nikhil, it depends on the budget you have. But, if all you need it for is daily city commuting, you can go for an entry-level or a mid-range model. No need to spend a lot of money for those needs.
Hi, I am a 5 foot woman 145 pounds and about 27 inch inseam. I am interested in purchasing a cruiser, Which would be best for me to purchase, a 24 or 26? Thank you.
Hi Peggy, both can be good in my opinion. A 24″ model will suit you well for sure. But, if you do not like the look of a 24″ bike, you can take a risk with a 26″ one as well. It might be a good fit as well.
Hi Jeff,
Thank you for this article – I didn’t know where to start until I stumbled upon this.
I’m about to buy an E-bike (brand new, not used) online but the Specs does not say its frame (or wheel) size… just that’s general adult. One reviewer says this is “One size: 53cm -CT, 48cm -CC” – What does that mean?
it also says:
seat height – 90cm to 111cm, 35″ to 43″
tires – 700C x 28C (made specifically for ebikes
I’m 5’5 (female) and not a super confident rider… from your article it looks like i should look for a 15-16′ frame. Does that “One size: 53cm -CT, 48cm -CC” work with what I hope to get?
thanks
Sunny
Hey Sunny, that bike would be too big for you. -CT stands for “Center to Top” and refers to the length of the seat tube from the bottom bracket to the top, where the seat post goes into the seat tube. -CC is similar and stands for “Center to Center,” it refers to the length of the seat tube from the bottom bracket to the point where the seat tube and the top tube meet.
Measure your inseam length, if it is smaller than 90cm/35″ (which is the minimum seat height as far as I can see from your info) it means that you won’t be able to ride this bike. Hope this helps. 🙂
Jeff, I desperately need your help. I’m looking at the Santa Cruz Megatower 29er or the Specialized Enduro 29er, maybe the Stumpjumper 29er. I seem to fall between a L and an XL. I’m 6’1”-6’2”, inseam 32-33. Which size would you recommend?
Hi Carlos.
For the Megatower, the 19″ (XL) would be the best fit. For the Enduro and Stumpjumper, I’d take the 19″ (L) frame 🙂
Hi, I’m 5ft10inch high inseam calculates as 33inch. Saw a northrock xc29 it’s a 29er, good price but only 17.5 frame size. I rode it. But confused if that’s the correct size. Can you advise
Hi Prasanth,
Yes, according to Northrock themselves, that’s the right size for your height. If you felt good when you rode it, feel free to go for it. ?
Hi I’m 5ft9.5 with a 32.5″ inseam and a hefty +15cm ape index! (monkey arms) I am looking at buying a 55cm orbea orca (they recommend a 53 on the website) I only have the option of a 55 as it’s clearance stock. They seem to recommend smaller sizes than most other companies.
Do you think it would be OK?
Cheers
Hi Kieran,
Yes, considering your impressive ape index, I think it should be fine. If it turns out to be too large, you can use a shorter stem and make it fit better. Happy riding. 🙂
Seems like your article is written for bike height not frame length. A 6’5″ rider can end up with to much stress on their hands, wrists, elbows, shoulders, lower back, hips, and knees from squeezing into a short frame with big wheels. You should add that. Meanwhile I will look elsewhere and hopefully find the info. What you did list was good though.
Hi Alan,
Thanks for the constructive comment, it’s always appreciated. The 6’5″ height that you mention is an extreme and in such cases it is harder to find the right fit. But, it can still be done with some adjustments. However, riders of average height will have no problem fitting nicely into the sizes we mention in this article. 🙂
Hello
My sis is 5ft. Im willing to buy a bicycle for her. plz suggest which bicycle should I buy?
Hi Shaheen,
First determine whether you’d like to buy a mountain, a city, or a road bike for your sister. After that, check out the charts in this article to determine which size you should aim for. Hope your sister will like the gift! 🙂
I’m 5’9″ with 32.5 inseam
What size is good for me?
Im 5 9″ what frame is good for me. I need a mountain bike.
Hi David,
The size you should be looking for is 17″ or 17.5″. Happy riding. 🙂
Hi Jeff,
I really appreciate this article…but I am still a little confused. I am a 6’2″ woman with a 37″ inseam. Long limbs, with a short torso. I was going to attempt to purchase a commuter bike online, but the size charts do not line up due to my leg length not matching my height. Could you help please? Thank you so much!
Hello Dawniece,
My advice is to go for the regular frame size for your height which will match your torso nicely. You can always raise the saddle up afterwards to accommodate for your long inseam. 🙂
Hi Jeff,
I’d bought Argon 18 go! (XS) for my wife and her height is around 162cm. Are this bike size really fits for my wife or I’d wrongly bought incorrect size (my friend told me i should get S size)….i’m a bit confusing right now.
I plannning to get another bike for myself…most probably Giant TCR Advanced…my height is 164.5cm and one retailer suggesting me to get a XS size too. But i want to get S size,…is there any problem with my choice or should i listen to retailer’s advise and stick to XS size…? Thank you in advance!
Hi Norashidi,
XS seems about right for your wife. However, in your case, it seems that both S and XS would be good, according to Giant’s sizing guide. But, I’d recommend going for the larger size and choosing S.
Hi Jeff,
It has been ages since my last time riding a bicycle. I am now looking for a city bike to use on weekend basis for recreational purpose. Recently, my husband bought a Retro Bike model: 7-SP, Brand: XDS. I found it a bit hard to handle as I am an asian petite woman (height: 149 cm, weight: 45kg), appreciate you could suggest the right size of city bike for me and perhaps the brand as well. Anyway, I want to ride a bike with my son seating at the back too.
Thank you ?
Hi Nabeila,
It’s great that you want to go back to cycling. Being that you are petite, I think you should go for a 26″ hybrid or cruiser model with a step-through frame, such as the Sixthreezero. Check out this review of the best bikes for women to learn more. Also, stay tuned as we will soon publish an in-depth review of Sixthreezero, so you can see if it suits you. 🙂
Hi Jeff
I’m going to buy a Vitus Sentier 275 MTB. I’m 5’8″ with 33″ inseam. Medium would fit my length, large is recommended for this inseam.
Which is the best choice?
Hi Anne,
In cases like these, if it’s possible you should try both sizes and determine which one suits you better. If not, try measuring the length of your arm span and comparing it to your height. If it’s greater than your height, choose L; otherwise, go for M. 🙂
Hi Jeff,
I haven’t ridden a bike in a while. Would a Women Hybrid bike be better for someone who doesn’t ride often and would a 26” be good for my height (5’ 3”)? Do you recommend a good brand?
Thank you in advance.
Hi Nancy,
Yes, I believe a hybrid bike would be great for you, as you can use it for multiple purposes. For your height, I would recommend a 15″-16″ frame size, either with 26″ or 700c wheels. Check out our Best Hybrid Bikes guide to find a great brand! It features some Women’s hybrid bikes as well, but all of them can suit you well with some minor changes. 🙂
I am 192cm tall, what would be my correct bike size?
Hi Mack,
The best bike size for your height is 18″-19″ or XL. It would be best if you first gave the bike a try if that’s possible since, depending on the manufacturer, an XXL frame might fit you fine as well.
What would be the proper advice when looking for a beach cruiser bike? I want to get bikes for my boyfriend and I so we can do this together but I’m finding this to be more challening than actually riding a bike
Hi Mollie,
Beach cruisers are bikes designed for leisurely rides, so the best advice is to get one that fits you well and that looks fun to ride. Check out our Best Hybrid Bikes guide to get some ideas and find something that you like. As with any other type of bike, make sure to choose the right size. 🙂
Hi there. Some asked this alr3ady but I was curious because 5’6″ is the cut off for two sizes on road bikes. It is the max at one size and the minimum on the next size up. Which is 5’3″ to 5’6″ and 5’6 to 5’9″. That is a big range. What do you recommend?
Hi Kenny,
If possible, it’s best to give both sizes a try and see which one fits better. This is a foolproof method. 🙂 Alternately, you can try to figure out your “Ape index.” Measure your height and your arm span, and then compare the two. If your arm span is greater than your height, go for the larger size. Otherwise, go for the smaller size.
Hi Jeff, I’m 1,42cm 35y old woman, not very good with bikes, lol. I’m so short that I usually don’t find my height in the size charts. I have a 26” women’s mountain bike, It’s almost the right size but I still can barely touch the ground, I feel I could use a smaller one, but not sure how small (frame and wheels). Is there a mountain bike size you would recommend? Thanks a lot
Hi Isabela,
There are some bike manufacturers that offer XXS frame sizes, so you should try to find some brand that fits your other requirements. Alternately, you can try a kid’s model with 24″ wheels, as these can be great for adults as well. Good luck! 🙂
Hey Jeff! Thanks for this article. It’s great. One question. I seem to be on the cusp of small and medium sized frames. I’m a female, 5’5” and 3/4, with like a 78 cm inseam. I saw a used Trek road bike for a great price with a small frame (52), but based on their website I could go either way with a 52 or 54 frame. It’s a nice investment, so I don’t want to get stuck with a road bike thats too small. What would you recommend? Appreciate your help!
Hi Julia,
I believe that would be a good size for your height. If possible, visit some local bike shop and try a random Trek road bike with a 52 cm frame to get an idea on how it fits. You’ll know what to expect then. 🙂
Hello Mr.Jeff,
I owned a road bike ‘ Felt’ brand with the size of 54 cm frame. I’m 170cm tall. Is there anything wrong with the size of the bike? Before this, i used to ride with MTB for 80km with no problems. But with this Road bike, I ride only 30km and my legs get cramp always. Is there something wrong with my bike?
Hi James,
That seems like the right size for you. Is your saddle properly adjusted? Make sure that it is not too low, there should be just a slight bend in your knee when you extend your leg. Also, road bikes put your body in a very different position than mountain bikes, so you might need some time to get used to the change. 🙂
You can read the Bike Fit article on Cycling Advice section
Hi I’m 5″9 and seen the perfect road bike for sale but it has a 21″ frame will this be to big for me? Unfortunately the bike is located quite a drive from me so trying it before I buy ain’t an option.
Many thanks in advance
Hi Lee,
Yes, unfortunately, I am afraid that bike would be too big for you. Good luck finding one that suits you better. 🙂
I’m looking to get a hybrid bike for my wife’s birthday. She is 5’2”. Would a 15” frame with 28” wheels work or does that seem to big?
Hi Evan,
That size sounds about right for her, but the standover height could be a problem. If it’s a step-through frame, then it shouldn’t be an issue at all. 🙂
Looking for a roadbike, but I’m seeing a lot of sizes in inches not cm. Do u have a conversion chart???
Hi Jessie,
Check out the Road Bike Size Chart in this article, it shows the bike sizes both in metric and imperial units. 🙂
Hi
My son is 4’5 100lbs and I’m not sure what size bike to get him
Thanks
Hi Teresa,
A 24″-wheel bike would be perfect for your son. 🙂
This absolutely BS. Every person body is different so every person needs to try different frame geometries and sizes in order to find a good fit.
Hi Marco,
You are right in that every person is different, however, everyone is also very similar, as we all fall in several categories. Therefore, the idea is to choose the right bike size for your ‘category’ and then make small adjustments with the seat, stem length, and so on. Hope this helps. 🙂
Hi Jeff,
I wanted to buy a used Fat Tire bike on Ebay, but it is M size frame and I need XL for my 6”2 height.
One thing I am trying to understand: the distance from the tube where saddle is to the tube where handle bar is. Is it the same for M and XL sizes?
Could I just adjust the saddle on M frame to fit my height but still be comfortable on the bike?
Thanks a lot in advance for your answer
Hi Vasily,
Show me the bike and I can share more information.
Hi jeff , i want to buy a bike . My height is 5.6 feet. What is my perfect bike size ?
Hi,
I’m sure you’ll find your answer here 🙂
Hi Jeff
I want to buy a racing bike but I cant decide on the right size. I am 1.75 cm height which is the changing size between M and M/L on a Giant frame. I cant try the bike before ordering it
What do you recommend?
Hi Emmanouil,
It’s best that you contact someone from Giant and ask what they recommend, they can surely help you out. Otherwise, you can measure your arm span and compare it to your height. If it’s greater than your height, go for the L frame. If it’s smaller, choose the M size. 🙂
My height is 170cm and what should be my bike size?
Hi,
I am sure you’ll find your answer by reading this article 🙂
I am 5’ 8” tall withan inseam of 29 inches. I just got a 51 cm road bike. Will this be okay for me?
Hi V,
That seems to be one size smaller than what you need. However, if you have no problems and it feels good riding it, just keep it up. Otherwise, you can make it fit better by fitting a longer stem and pulling your seat back a bit. 🙂
Hi Jeff,
I have a question does the Amazon Fit Guide charts or any other chart of mountain bikes apply for the hybrid? because none of them mentioned the hybrid bike
Hi Medhat Ishak,
Mountain bike size charts can differ from city/hybrid bike size charts, so you should not rely on them 100%. But, you can use them to get a better idea of what you need. 🙂
I’m 6’9″ and 355lbs. Other than an immediate XXL mountain bike, what is a good way to find something I don’t feel I’m going to break? I have 3 kids 5 years old and younger and I want to be able to ride with them. I also don’t want to spend more than $400 on a bike so my best bet would be to find a used one. What are some models that I should be looking for?
Hi Micah,
I recommend the so-called “Fat Bikes” for you, as they have very wide tires and are very durable overall. They can carry riders of around 350 lbs. Check out the Kawasaki Mihara, which we have reviewed on our website. You can get a new one for less than $500. 🙂
I am easily confused, looking at the various ways to chose the right size road bike, I believe one chart shows an inseam of 78cm equals a bike size of 53cm. Another chart shows height of 5.9 to 6.0 feet equals a bike size of 56 to 58 cm.
I am looking for a flatbar bike and I see the Kestrel RT 1000 Shimano 105 advertised for $1,115.00 but I am not sue what size to order.
I am 5 feet 10.5 inches tall and an inseam of 31 to 32.
Can you help me with what cm bike to purchase?
Thank you
Hi David,
The best bike size for you would be 56/57cm or L. Your inseam of 32″ equals 81.82cm x 0.70 = ~57cm 🙂
Moving the seat back or forward may be okay for those who ride once in a while. It can affect power transfer or cause pain. The solution is to get the right bike fit. I once bought a used road bike that was one size too large. The staff didn’t seem to know that it was too large and I thought that feeling stretched out was normal. I ended up giving it to my friend who’s a little taller than me.
Hi Han-Lin,
You’re right, nothing can substitute choosing the right size and it’s difficult to make it feel perfect if you have the wrong size. However, if you are in-between two sizes or you’re just slightly off, adjusting the saddle or changing the stem can be great solutions. 🙂
Hello, great text. I want to buy Cube Reaction Pro 2019 but don’t know right size, please can you help me..I am male 187 , but my leg inseam is 89 cm. Thank you
Hi Ivo,
According to Cube’s size chart, the right size for you would be 19″, or XL. 🙂
Hi I have a size 50 bike and my height is 165 and inner is 75 what should the saddle height be
Hi Gerald, it’s hard to say. Ideally, your leg should have just a slight bend in the knee when you extend your leg fully on the pedal. Play with it until you find a position that feels comfortable.
Hi, thank you for this guide.
Im a 5’8 woman, slim build and a 31″ inseam.
Im looking at a bike the owner says the seat tube is 19″ at its shortest. Im finding a lot of discrepancies on the internet about sizing. The bike is an Azuki Sebring if that helps
Hi Shelby,
That does not sound like the right fit for you. You should look for a road bike with a 52 cm frame or a mountain bike with a 16″/17″ frame. Happy riding! 🙂
Hi Jeff I’m 6 foot 6 will a 23 inch bike be big enough
Hi Ross,
Sure, a 23-inch bike sounds like a good fit for you. If possible, it’s best to give it or some similar bike a try, as it’s not a very common height and bike size. Good luck! 🙂
Hi Jeff,
Iam looking to by a hybrid for city ride and could you please help me in providing the frame size and tire size as well.. Iam 5’5..
Hi Srinivas,
A 15″/16″ bike would be great for you. If the standover height is not an issue, feel free to go with 700c wheels as they have many benefits when it comes to city riding. 🙂
Hi Jeff, I fall in between 2 sizes. I am 5th 6 inches which is the max height for S and minimum height for M. For a road bike which size should i choose?
Hi Rajarshi Ghosh,
The best thing to do is to try both bikes and see which one fits better. If that’s not possible, you can measure your arm span and compare it to your height. If it’s greater than your height, go for the larger size; if it’s smaller, go for the smaller size. Good luck. 🙂
Hi Jeff
I find your article very useful. Great work!
I am 5’7″. I got a bike size of 58cm before reading your article (i wish i read it before). Do you see a problem in long run? Or adjusting saddle height and position is ok. I’m using it to commute to work, roughly about 16km every day.
Hi Rihit,
Thanks, I’m glad you like the article! 🙂
Regarding your bike, it’s definitely too large for you. Adjusting the saddle could make it feel better, but it will never make it feel perfect. However, if you feel no aches and have no problems during or after riding it, I say just go for it.
Hi Jeff, I also have a lot of trouble finding a good bike for me. I am 1.51cm height, 32-year-old woman, also I am not too good riding and get terrified of falling over. last time I bought a girls’ bike, with 24” wheels, because I wanted to be able to put my feet in the ground. But to be honest, I feel the bike doesn’t quite fit me! I am considering getting a new one. What would you recommend I look for?
Hey Adriana, I think a regular 26” women’s bike with a step-through frame should be good for you. It will fit you well, and it will be easy for you to put your feet on the ground. Good luck!
Hi there
Does this information also apply to the BMX styles? I’m getting bit by the vintage restoration bug, and my 13yr old son wants an old school BMX. He is roughly 5’5….. just wanting the easiest method for sizing bmx styles- including the bmx style cruisers
Hi Joel, BMX bikes use a slightly different sizing method. The best size for your son would be the so-called Pro frame. It has 20” wheels and a top tube length of 20” – 20.5”.
Hi jeff,
My height is 5”5 & inseam is 70 cm.. I want to buy Roadbike. Should I go for medium size? Is there any specific difference between mediuyand small size? Because one of my friend have medium size and he wants to sell it.
Hello Swapnil, it seems that a Small size would be more suitable for you. However, it depends on the proportions of your body. Since you’re looking to buy a bike from your friend, it’s best to give it a try and see if it fits. If it’s too big, try adjusting the saddle height and using a shorter stem. Cheers!

She is 6 years old
Hi,
16″ to 18″ frame should be okay!
Hi Jeff
I am searching a bicycle for my daughter whose overall height is 46 inch and inside leg height is 21 inch. This gonna be her first cycle for learning.
1) Could you please tell what would be correct frame size, wheel diameter size for her.
2) Does purchase from online sites like Amazon or flipkart, will land me in trouble by missing some items in package since they are partially assembled.
Hi Pratap,
How old is your daughter?
I want to try biking again and want to buy used to start. I’m looking at a ccm 26 inch frame I’m 6’4 would that fit me?
Hi Darrell,
Yes, that sounds like the right size for you. Happy riding! 🙂
I have awful trouble with bikes… never seem to quite get the right size.!!!!
I’m 6ft 3in and a 35in inside leg with size 8 feet and large hands ( I have Marfan syndrome) this means my body is not in proportion !!!! And on top of this….. I’m a woman who loves cycling ???????
Hi Diane,
Since size graphs are quite standard, you might want to try bikes in your local bike shop. Be ready for some stem and saddle adjusts.
Happy cycling 🙂
Thank you for this information! One question… how should we factor in wheel sizes? Is there a rule on choosing wheel size?
Hi Erin,
Read this Cycling Advice article https://www.bicycle-guider.com/cycling-advice/how-to-choose-bike-tires/ 🙂
Hi. I’m 6’2″ and looking at a used Giant that is 56mm. would that work for me? I’m finding few 50-60cm for sale (used)
Hi Mike,
It’s hard to tell since, according to the charts, that is one size smaller than the one you would ideally need. However, with smaller adjustments, you could make it work. If possible, give it a try to see how it feels.
Hi I need a three wheeler bike for my 5ft daughter will 24″ suit?
Yep Kay, it should fit
Hi Jeff
I seem to fall in between frame sizes. I am 6’4 with a 33” inseam. What would you suggest.
Hi Chris,
Depending on the models. Look the merchant’s size charts. Everything above 19″ and 62cm on road bikes will work.
Hi Jeff! What is the best place for Christmas pressies? I want to buy a bike for my 2 y/o daughter.
Hi Dawie,
Have a look here https://www.bicycle-guider.com/christmas-gifts-for-cyclists
Hi I’m confused. Your charts have a maximum 22 inch frame. Yet you have a 29 inch, and think 26 is tiny. Are you a giant or am I misunderstanding something here…?
Hi Chris. 26″, 27.5″ & 29″ are bike wheel sizes. 22 is bike FRAME size. We make an update to clarify it 🙂
Information which you have provided are really useful for the all people. Thank you so much for the information.
But i need to know one thing, Let consider my height is 6.0” but i bought frame size M/L or ( 16” to 19”) frame size bike. Can I adjust the saddle based on my height or that is not recommended. If not recommended please let me know why?
Yes, you can adjust your saddle to the right height. It’s a final tune to get the right fit.
I am 157cm. what frames size do I need to use in mountain bike 29, road bike and TT bike?
Hi Jordan,
Your ideal sizes are:
-MTB: 14″/15″
-Road: 50cm
-TT: 50cm
Really helpful and comprehensive information on bike size. It’s to pick the right size for me without trying. However, with this bike size chart, I can easily find the most suitable bike. Already shared it with my friends and bookmarked it. Thank you for making the comprehensive guide and nice infographic Jeff.
I am in agreement with Anna I am 5-8 and have an inseam of 32 and a bit and I see the author is saying for women choose by height, I would ask why?
If you go by height then a person’s legs would be crammed in the space between the pedals and seat which means you have to raise the seat up a lot, why would it not be better to go by inseam and not have to raise the seat up so high?
Hi Toni,
That’s a good point, but most people are usually well balanced when we compare the length of the torso and the legs. This is even more true for women since it’s more common for men to have very long legs compared to the rest of their body. Therefore, women can usually make a good choice by just choosing by height, but there are always exceptions. 🙂
Hi
I find this very confusing! Also, I’m sure you have noticed that women tend to have much longer legs than men do for the same height, (while men have longer bodies) and your charts are clearly geared towards men. You need separate charts for men and women. Even your chat using inner leg length is way out for me (as a female).
Hi Anna,
You are right – leg inseam method is not the best for women. Feel free to choose your bike by looking for overall height.
