A calculator to find out your step or stride length from the steps and distance walked or the number of steps from the lengths. To get your personal average step length, you should walk a distance not too short, of exactly known length, without any peculiarities and at a normal pace. Thereby, count your steps. Well suited is something like a running track on a sports ground. The measurement becomes more accurate with longer distances measured.
In addition to determining the stride length for a known route, this website also serves to estimate the number of steps if you already know your stride length. The stride length of different individuals is of course different, but it also changes for one person at different running speeds, gaits and terrain, so this extrapolation is not particularly accurate, especially for very varied routes. A direct measurement is more accurate, but of course this does not take place here, because there is no contact between the website and the person running or walking. Pedometers that measure steps directly can be found on a smartphone or smartwatch, for example. The smartphone detects movements via a sensor and then interprets them as steps or other movements. This works quite well, but not perfectly. The number of steps on the smartwatch is not exact either, because it is attached to an arm rather than to the leg. The smartwatch's pedometer can be easily tricked by letting the arm it is attached to dangle back and forth. Of course, this is mostly self-deception.
