Step 2: Calculate your frame size
Based on the so correctly measured step length, the proper frame size (individually different for each bike type) can be defined by means of an approximate calculation: The measured numerical value in centimetres is now multiplied by a certain factor (different for each bike category). The result is the frame size in inches (1 inch = 2.54 cm).
Enter the value measured in centimeters in the white calculation window and click "calculate".
Frame Size Calculator
If your chosen bike isn't available in the calculated frame size, the following rules of thumb apply:
for sporty riding you rather choose the smaller frame size.
You want to ride more comfortable, choose a larger frame size.
If you use a suspended seatpost, you should subtract approx. 3cm (or 1 inch) from the calculated size.
NOTE: Please also notice the respective standover hight you can find in the geometry table!
