Calculate your average step length by tracking the number of steps over a known distance traveled. This can be used to get a more accurate measure of the total distance you walked.
In this calculator, step length is the length of one footstep (i.e., left heel to right heel). Step length is sometimes referred to as stride length but the actual definition of stride length is the distance traveled in two steps (i.e., left heel to left heel). In other words, just double step length to find your stride length.
