Bike Size Charts & Finding the Right Size Cycle

How-Tos & Tips

Written by:

It is tempting to order a bike online as you often get great deals! For this you must know what is the right cycle size for you.

In fact, even when buying a bike from a store you should know the right size for your body; and avoid leaving the store with a bike that is small for you (and will make you hunch) or one that is big (and will make you overreach with your arms and legs).

Bike sizes differ between men’s and women’s bikes, and between types of bikes – MTB, hybrid and road cycles. Different brands follow different size charts as well. So, never just look at Small size, Medium or Large size. Find the right size for you below by using one of 3 methods.

Method Two: Calculating the bike size

If we get into a little more detail, then it is not your height alone that dictates the right size cycle for you. It is actually your inseam length that matters, the length a tailor measures from your crotch to the ground when measuring you for pants. That’s because a taller person may have short legs and a shorter person may have long legs.

  1. Take off your shoes and stand with your feet about 6 to 8 inches apart. Measure your inseam length (crotch to ground length).
  2. Be sure of what type of cycle you want: an MTB (mountain bike), a Hybrid (city) bike or a Road bike. You can read about the different types of cycles here.
  3. Now calculate the right cycle size using this formula.

Hybrid bike: Your frame size = Leg inseam (cm) x 0.685

Mountain bike: Your frame size = Leg inseam (cm) x 0.66

Road bike: Your frame size = Leg inseam (cm) x 0.7066

If your leg inseam is 76cm, then the city bike for you is 52cm, MTB is 50cm or 20 inches, road bike is 53cm.

Here is a cycle size chart combining with both inseam length and rider height:

The right cycle size ensures that you have good clearance between your crotch and the top tube in a cycle, not less and not too much. Apart from cycle size, its geometry is also good to consider when buying a cycle.
