The Numbers. Stride length is measured from heel to heel and determines how far you walk with each step. On average, a man's walking stride length is 2.5 feet, or 30 inches, according to Arizona State University Extension.A woman's average stride length is 2.2 feet, or 26.4 inches, reports the school. In general, people with longer legs have a greater stride length than those with shorter legs.nother method is to step in a puddle of water, walk 10 steps and measure the stride length between three wet steps. Average those distances to find your average stride rate. For example, if you measure 29, 30 and 31 inches per step, you have an average stride length of 30 inches.
