A calculator for the optimal height of a bicycle saddle. The calculation is simple: the ideal saddle height is 109 percent of the inside leg length, which is the length from the crotch to the floor when standing upright and wearing shoes for cycling. The saddle height is the distance from the saddle to the bottom pedal along the line of the outstretched leg, not its height above the ground.
The correct saddle height is important for good posture when cycling so that incorrect strain does not occur. Such incorrect strain can reduce training success and be painful, and in the long term it can also cause permanent damage. If the saddle is too low, the knees are put under too much strain, and if the saddle is too high, the sit bones suffer. The saddle is often set too low so that you are closer to the ground and therefore have a greater feeling of security. But ergonomically this is not good.
The handlebar height is also important, but this depends on the type of bike. You should find out more about this for your bike. For example, you sit differently on racing bikes than on city bikes. In any case, you should avoid a rounded back. When buying a new bike, it is definitely advisable to have a competent dealer show you the correct settings for your size.
