Today we’re going to show you how to calculate the ideal size of your fixie bike, so that you’ll be able to order a bike on the internet while being 100% sure that the size will fit you. Let’s get to it!
Fixie bikes and city bikes are very similar to the road bikes everybody has been using and hearing about for a long time now. The shapes of both types are quite similar, especially with economic or medium-range models.
That means if you have an old 54-cm road frame, your fixie bike should be the same size.
Bicycle size chart based on height
To know the size of city bike or fixie that best suits you, one option is to guide you by your height.
|Your Height||Size in centimeters||Size in inches|
|155-165 cm||46, 47, 48||18, 19|
|165-170 cm||48, 49, 50, 51||19, 20|
|170-175 cm||51, 52, 53, 54||20, 21|
|175-180 cm||54, 55, 56, 57||21, 22|
|185-190 cm||57, 58, 59||22, 23|
|+190 cm||59, 60, 61, 62||23, 24|
This may be the right option for a rough idea, but isn’t always the best way. If you are 180cm tall, you may find yourself between two suggested sizes (56 and 59cm) depending on the manufacturer. In these cases, if you are between two sizes, it will depend on the use of bike use ; for city you must choose the largest size and for the track, the smallest – for urban cycling, you’d better have a handy bike which allows you to set your feet on the ground in any situation, such as an encounter with a car or when facing a red light.
However, the size also depends on the brand and the geometry of the bicycle model.

In Santafixie we have developed an automatic system where you enter your height and we recommend the ideal size that is closest to your height. You can test in this bike, you have to click the button “SIZE GUIDE” which is just below where the bike size is chosen.
How can you measure your legs?
You must stand barefoot with your back against a wall and measure the distance (in cm) from the ground to the groin, basically the part of your body that is sitting on the saddle. It’s good to use a stick to pull your pants up, so that you don’t get a shorter figure.
If you want to calculate the size for an urban bicycle or fixie you must multiply your crotch height by 0.65.
Then you’ll have to multiply that number by 0.65 (although some experts also mention 0.64). Thus, if our legs are 80cm long, we shall get a size-52 model.
It’s relatively easy to get the right size, as you can see. If you are 188cm tall, you’ll almost certainly need a size 58 or 59. But if you’re not sure, you can just measure your legs and be 100% sure.
Take into account that the seatpost height can be adjusted up and down, so you’ll have several centimetres of play to adjust the saddle until you get the perfect height.
