Sizing - Bikes

Find Your Bike Size

The key to finding the proper bike frame size is by measuring your total inseam (not pant inseam) while wearing your cycling shoes, and then comparing it to the standover height of the bike. We attach sizing charts to every bike we sell on REI.com to help you determine the correct size and fit.

For more information on sizing a bike and measuring your inseam, please see our Expert Advice article, Bike Fitting Basics.


How to Size Your Bike

  1. With shoes on, measure from your crotch to the floor. This gives you your inseam length.
  2. Find the standover height on the bicycle sizing chart.
  3. For mountain, touring, urban and comfort bikes, the difference between your inseam length and the standover height should be around 2 inches; for road bikes, this difference should be around 1 inch.
