Measuring Your Size the Traditional Way

Getting the right bike size is essential — especially if it’s your first bike — as it directly affects comfort, efficiency, and overall enjoyment. While modern tools like our Online Size Guide make sizing easier, you can also find your size the traditional way by measuring your inseam and following the general guidelines below.

Measure your inseam

The most important factor when choosing the frame size is your Inside Leg lenght (inseam). Basically it is distance from the floor to the highest possible crotch position.

The best way to do it is to undress (baggy or wide cut trousers, shoes cause mistakes) and find the highest possible crotch position. For this purpose you can use spirit level or even book, but remember it has to be completely horizontal. Measure the distance from the top of the spirit level (or the book) to the ground. If having problems ask somebody for help. For accuracy, repeat the measurement several times and calculate the average.

To maximize comfort and performance on the bike, proper fit is essential - even more important than frame materials and components. To find proper size of your Racing frame may take some time.

First, most general option is body measuring and using tested formulas:

Lapierre & NeilPryde: Your Frame Size = Inseam (cm) x 0.62
Cannondale, Cube, LOOK, Pinarello & Scott: Your Frame Size = Inseam (cm) x 0.67
