Wheel Circumference Calculator — For Bike Computer Setup
Find the correct wheel circumference for your tyre size.
How We Calculate This
Wheel Circumference Lookup
This calculator uses a lookup table of commonly accepted circumference values for standard tyre sizes. These values are averages across manufacturers.
For the most accurate result, perform a roll-out test: mark the tyre, ride in a straight line for one full revolution, and measure the distance.
