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.
Average Stride Length. Stride length can mean the same thing as step length, or it can mean the distance traveled by the heel of one foot to the next time that same foot strikes down. In other words, that would be two steps since in that time the other foot has also touched down once.
