Step length is the distance between successive contacts of opposite feet. This calculator returns distance per individual step, which lets you convert a step count into distance. A full stride covers two steps; do not use a full-stride distance with a count of individual steps.
How the Stride Length Calculator works
The most accurate way to find step length is to measure it directly: walk or run a known distance, count your steps, and divide the distance by the step count. This works regardless of your height, gait style, or pace, because it captures your real step rather than an average.
When a measured distance isn't available, the calculator falls back to standing-height ratios drawn from gait-analysis research: walking step is typically about 0.415 times height, while running step — which includes an airborne "flight phase" between footfalls — stretches to roughly 0.65 times height. These are population averages, so an individual's actual step can vary based on leg length proportion, pace, fitness level, and terrain.
Inputs and what they mean
On the "From Steps" tab, enter the distance you covered (miles or kilometers) and the total steps counted over that distance — a smartphone pedometer or a manual tally both work. On the "From Height" tab, enter your standing height (in decimal feet or centimeters) and choose Walk or Run; the calculator applies the matching ratio. The Activity toggle on the Steps tab is for labeling only, since distance ÷ steps is exact no matter the activity.
Most adults have a step length between 2.1 and 2.7 feet (0.65–0.83 m) walking, and 3–5 feet (0.9–1.5 m) or more running, though sprinters and very tall individuals can exceed that range considerably.
Limits and edge cases
Height-based estimates assume an average build and gait; they will be less accurate for people with unusually long or short legs relative to height, an altered gait from injury, or a very brisk or very relaxed pace that changes step beyond typical ranges. For anything precision-sensitive — race pacing, treadmill calibration, insole or shoe fitting — use the measured (From Steps) method over a real, ideally longer, distance to average out step-to-step variation.
