The following bike frame size charts and calculators give you a good starting point on what size bike will fit your body. Sizing a bicycle is not an exact science, so consider this a general guide. You still may want to get a professional fitting from your local bike shop when buying a bike. In order to use the charts, you should have your height and leg length measurements (in either inches or centimeters). You can navigate this guide using the links below:
