Choosing The Right Frame Size

The key measurement in determining the right frame size is the distance between the pedals and the saddle - or the distance between the ball of the foot and groin.

Frame sizes are identified using the measurement of the seat tube.  Most bike manufacturers measure from the center of the bottom bracket to the center of the top tube.  So, a 56 cm bike will have a seat tube length of 56 cm.

One rule of thumb for an average built male to find the appropriate bike size is to measure the inseam from groin to the floor in stocking feet.  Subtract 10 inches (25.5 cm) from this measurement, convert it to metric, and it will be a good estimate of frame size when measured from the center of the bottom bracket to the top of the seat tube.  This table from Bicycling Reviews gives a good overview of the sizes of bike frames for the typical male rider.

 

Frame Size gridOf course, not everyone is an average built male.  Foot size and relative leg length will impact frame size selection.  Women’s proportions are different from men’s, as well.  A woman’s legs are often longer than a man’s of the same height.  Women’s specific designs take these differences into consideration and are an increasingly popular option for racers.

Track racers typically choose bikes one centimeter smaller than their road bikes because the seat tube of a track bike is more vertical.
