Bike Size Chart – How To Choose? 5 Easy Methods

Jeff Balton

Choosing the right size bicycleOrdering bikes online is becoming more and more popular because there are no shop-keeping or warehouse costs making the cost even less!

Don’t worry about the fact that you might think you have to try your bike first because I can assure you it is overrated. And very highly.

Salesmen only tell you this to get more money from you!

You should try your bike first! FALSE

Asking why? It’s because that is only told by salesmen who know that there are decent bikes on the online market. There are many good methods to choose a good bike. I’m gonna show you THREE (actually SIX!) METHODS if you don’t know, how to measure a bike.

Feeling more confident? Good. There are actually three (now SIX!) options: you can calculate or use the bike-size charts below. The bike size is measured from where the seat post starts and to the crank. So if you don’t know, what size bike do I need, here are the answers:

Let’s start with the easiest

Method One: Bike Height Chart – The Easiest

Your height / Bike SizeHybrid Bike Size Chart

  • 4’11” – 5’3″ = 13 – 15 inches
  • 5’3″ – 5’7″  = 15 – 16 inches
  • 5’7″ – 5’11” = 16 – 17 inches
  • 6’0″ – 6’2″ = 17 – 19 inches
  • 6’2″ – 6’4″  = 19 – 21 inches
  • 6’4″ and taller  = 21+ inches

Voilà!

Method Two: Calculating the bike size:

  1. Take off your shoes and stand with your legs about 15-20 cm(6” – 8”) apart. Measure the height from the ground to your crotch.
  2. 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.
  3. Now you can take your calculator and calculate the right size:
    Leg Inseam method

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 Right Saddle Heighthas 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!

 Need Professional Fitting Service? Order From Amazon!

The easiest way is to

  1. Lean to the wall with your elbow sitting on the bike (or let someone help you as shown on the picture)
  2. But your leg to lowest point but parallel to the ground.
  3. Move your saddle up or down until you have 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.

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.

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.

  • Anna Bean says:

    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).

    • Jeff - Senior Writer/CEO says:

      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.

  • Bee says:

    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.

    • Toni says:

      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?

    • Jeff Balton says:

      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. 🙂

  • Jordan Schleck says:

    I am 157cm. what frames size do I need to use in mountain bike 29, road bike and TT bike?

  • Vinoth says:

    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?

    • Jeff - Senior Writer/CEO says:

      Yes, you can adjust your saddle to the right height. It’s a final tune to get the right fit.

  • Chris says:

    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…?

    • Jeff - Senior Writer/CEO says:

      Hi Chris. 26″, 27.5″ & 29″ are bike wheel sizes. 22 is bike FRAME size. We make an update to clarify it 🙂

  • Dawie says:

    Hi Jeff! What is the best place for Christmas pressies? I want to buy a bike for my 2 y/o daughter.

  • Chris says:

    Hi Jeff

    I seem to fall in between frame sizes. I am 6’4 with a 33” inseam. What would you suggest.

    • Jeff - Senior Writer/CEO says:

      Hi Chris,

      Depending on the models. Look the merchant’s size charts. Everything above 19″ and 62cm on road bikes will work.

  • Kay foulds says:

    Hi I need a three wheeler bike for my 5ft daughter will 24″ suit?

  • Mike Smith says:

    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)

    • Jeff Balton says:

      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.

  • Erin M says:

    Thank you for this information! One question… how should we factor in wheel sizes? Is there a rule on choosing wheel size?

  • Diane Summers says:

    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 😀😀😀😀😀😀😀

    • Jeff - Senior Writer/CEO says:

      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 🙂

  • Darrell says:

    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?

  • Pratap shingte says:

    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.

  • Pratap shingte says:

    She is 6 years old

  • Swapnil Desale says:

    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.

    • Jeff - Senior Writer/CEO says:

      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!

  • Joel Julian says:

    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

    • Jeff - Senior Writer/CEO says:

      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”.

  • Adriana says:

    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?

    • Jeff - Senior Writer/CEO says:

      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!

  • Rihit says:

    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.

    • Jeff Balton says:

      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.

  • Rajarshi Ghosh says:

    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?

    • Jeff Balton says:

      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. 🙂

  • Srinivas says:

    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..

    • Jeff Balton says:

      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. 🙂

  • Ross Turner says:

    Hi Jeff I’m 6 foot 6 will a 23 inch bike be big enough

    • Jeff Balton says:

      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! 🙂

  • Shelby says:

    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

    • Jeff Balton says:

      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! 🙂

  • Gerald says:

    Hi I have a size 50 bike and my height is 165 and inner is 75 what should the saddle height be

    • Jeff Balton says:

      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.

  • Ivo says:

    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

    • Jeff Balton says:

      Hi Ivo,
      According to Cube’s size chart, the right size for you would be 19″, or XL. 🙂

  • Han-Lin says:

    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.

    • Jeff Balton says:

      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. 🙂

  • David Miller says:

    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

    • Jeff Balton says:

      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 🙂

  • Micah says:

    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?

    • Jeff Balton says:

      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. 🙂

  • Medhat Ishak says:

    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

    • Jeff Balton says:

      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. 🙂

  • V says:

    I am 5’ 8” tall withan inseam of 29 inches. I just got a 51 cm road bike. Will this be okay for me?

    • Jeff Balton says:

      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. 🙂

  • Alif says:

    My height is 170cm and what should be my bike size?

  • Emmanouil says:

    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?

    • Jeff Balton says:

      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. 🙂

  • Kick says:

    Hi jeff , i want to buy a bike . My height is 5.6 feet. What is my perfect bike size ?

  • Vasiliy says:

    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

  • Marco Manzo says:

    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.

    • Jeff Balton says:

      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. 🙂

  • Evan says:

    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?

    • Jeff Balton says:

      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. 🙂

  • Lee scales says:

    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

    • Jeff Balton says:

      Hi Lee,
      Yes, unfortunately, I am afraid that bike would be too big for you. Good luck finding one that suits you better. 🙂

  • James says:

    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?

    • Jeff Balton says:

      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. 🙂

  • Julia says:

    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!

    • Jeff Balton says:

      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. 🙂

  • Isabela says:

    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

    • Jeff Balton says:

      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! 🙂

  • Kenny says:

    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?

    • Jeff Balton says:

      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.

  • Mollie says:

    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

    • Jeff Balton says:

      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. 🙂

  • Mack says:

    I am 192cm tall, what would be my correct bike size?

    • Jeff Balton says:

      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.

  • Nancy says:

    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.

    • Jeff Balton says:

      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. 🙂

  • Anne says:

    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?

    • Jeff Balton says:

      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. 🙂

  • Nabeila Ghazali says:

    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 😊

    • Jeff Balton says:

      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. 🙂

  • Norashidi says:

    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!

    • Jeff Balton says:

      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.

  • Dawniece T. says:

    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!

    • Jeff Balton says:

      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. 🙂

  • David says:

    Im 5 9″ what frame is good for me. I need a mountain bike.

  • David says:

    I’m 5’9″ with 32.5 inseam
    What size is good for me?

  • Shaheen says:

    Hello

    My sis is 5ft. Im willing to buy a bicycle for her. plz suggest which bicycle should I buy?

    • Jeff Balton says:

      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! 🙂

  • 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.

    • Jeff Balton says:

      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. 🙂

  • Kieran says:

    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

    • Jeff Balton says:

      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. 🙂

  • Prasanth says:

    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

    • Jeff Balton says:

      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. 🙂

  • Carlos Cervantes says:

    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?

    • Jeff Balton says:

      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 🙂

  • Sunny says:

    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

    • Jeff Balton says:

      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. 🙂

  • Peggy Mathis says:

    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.

    • Jeff Balton says:

      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.

  • Nikhil Dharmendrakumar Rajput says:

    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?

    • Jeff Balton says:

      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.

  • Mark G says:

    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.

    • Jeff Balton says:

      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.

  • Amjed says:

    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

  • Brian Nagy says:

    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?

  • Abdelrahman salah says:

    Hi jeff,iam 172cm and my inseam 76 and i need a road bike what’s the frame is suitable for me

    • Jeff Balton says:

      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.

  • Nikolay says:

    I did a mistake trusting to the according tables.

    • Jeff Balton says:

      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)?

  • Lou says:

    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?

  • GG says:

    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!

    • Jeff Balton says:

      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.

  • Amer Demirovic says:

    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

    • Jeff Balton says:

      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.

  • Frank says:

    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.

    • Jeff Balton says:

      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.

  • Darren says:

    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?

    • Jeff Balton says:

      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.

  • RW says:

    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

    • Jeff Balton says:

      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. 🙂

  • David says:

    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.

    • Jeff Balton says:

      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.

  • Aakash S says:

    Hi,
    My height is 185.5cm but my inseam is 90cm what size should I go in Cannondale and Merida road bikes.?

    • Jeff Balton says:

      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.

  • Lisa says:

    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?

    • Jeff Balton says:

      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.

  • Rob Wilson says:

    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!

    • Jeff Balton says:

      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. 🙂

  • Caryn Naphakdy says:

    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!

    • Jeff Balton says:

      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.

  • Shell says:

    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?

    • Jeff Balton says:

      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. 🙂

  • Mikey D says:

    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.

    • Jeff Balton says:

      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. 🙂

  • Stoyan says:

    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

    • Jeff Balton says:

      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.

  • Sarah Casey says:

    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?

    • Jeff Balton says:

      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.

  • Alicia Hatfield says:

    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?

    • Jeff Balton says:

      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. 🙂

  • Arvind KaswaN says:

    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

    • Jeff Balton says:

      That sounds to be about the right size for you. You can always adjust the saddle position and the stem if need be. 🙂

  • Giana says:

    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?

    • Jeff Balton says:

      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.

  • Rick Critchlow says:

    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.

    • Jeff Balton says:

      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. 🙂

  • Viktor says:

    • Jeff Balton says:

      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!

  • Brent Kabat says:

    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

    • Jeff Balton says:

      Hi Brent, I always advise choosing the larger size when you are in-between two sizes. So, I recommend choosing Medium in your case. 🙂

  • JO S says:

    Wanting to buy hybrid bikes. Can you help on on sizes?

    • Jeff Balton says:

      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! 🙂

  • Jacques says:

    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?

    • Jeff Balton says:

      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.

  • James says:

    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?

    • Jeff Balton says:

      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.

  • 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?

    • Jeff Balton says:

      The frame size is always shown in inches. The riders’ height is shown both in inches and in centimeters.

    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.

    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.

    • Jeff Balton says:

      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 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.

    • Jeff Balton says:

      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. 🙂

  • Ryan says:

    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?

    • Jeff Balton says:

      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 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

    • Jeff Balton says:

      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.

  • Katrina says:

    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!

    • Jeff Balton says:

      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. 🙂

  • Ken says:

    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?

    • Jeff Balton says:

      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! 🙂

  • Denis says:

    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?

    • Jeff Balton says:

      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! 🙂
