How it works
distance = steps × (height × stride factor)
Distance is simply your number of steps multiplied by your stride length, and stride length scales with height. A widely used estimate puts walking stride at about 0.414 × your height and running stride at roughly 0.65 × height, since running steps are longer. So a 1.70 m walker has a stride near 0.70 m, and 10,000 steps cover about 7.0 km (4.4 miles). Calories are estimated from body weight and distance — roughly 0.53 kcal per kilogram per kilometre walking and about 1.03 running — so a 70 kg walker burns around 260 kcal over those 10,000 steps. Stride and energy cost vary between people, so treat the numbers as solid estimates rather than exact measurements; a measured stride gives the most accurate result.

- Stride length from height Stride length is commonly estimated as a fraction of height — about 0.414 × height for walking and roughly 0.65 × height for running.
- Energy cost of walking and running Distance-based estimates of around 0.5 kcal·kg⁻¹·km⁻¹ (walking) and ~1.0 kcal·kg⁻¹·km⁻¹ (running) are widely used approximations of net energy cost.
- Steps-per-mile context Average adults take roughly 2,000–2,500 steps per mile walking and fewer running, depending on height and pace.
FAQ
How many miles is 10,000 steps?
For an average-height adult, about 4 to 5 miles walking. The exact figure depends on your height and stride — a taller person covers more ground per step. Enter your height to get a personalised distance rather than a generic average.
How is my stride length estimated?
From your height: roughly 0.414 × height for walking and about 0.65 × height for running. These are population averages, so if you know your true stride length (measure a set number of steps over a known distance) your real distance may differ slightly.
Why does running cover more distance per step?
Running uses a longer, more powerful stride than walking, so each step travels farther. That is why the calculator applies a larger stride factor for running and, for the same step count, returns a greater distance.
How accurate are the calories?
They are an estimate based on your weight and the distance covered, using typical energy costs for walking and running. Real expenditure depends on pace, terrain, fitness and efficiency, so use the number as a guide for comparing activity, not an exact total.
How many steps are in a mile?
Commonly around 2,000–2,500 walking steps per mile for an average adult, and fewer when running because of the longer stride. The calculator shows your personal steps-per-mile based on the height you enter.
Does step length change with speed?
Yes. Faster walking and especially running lengthen your stride, so a brisk effort covers more distance per step than a slow stroll. This tool uses one walking and one running estimate; for precise tracking, a GPS watch measures actual distance directly.
Distance and calories are estimates from your height, weight and average stride models, not exact measurements. Individual stride and energy cost vary. General information for activity tracking, not medical advice.
