Bike Sizing Charts By Brand

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 stand-over height on the bicycle sizing chart ("A" in the illustration at right).
  3. For mountain, touring, urban and comfort bikes, the difference between your inseam length and the stand-over height should be around 2 inches; for road bikes, this difference should be around 1 inch.
