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.
