Average Step Length by Height
A step length is personal, but the range is narrow enough to make a useful default.
What an average hides
"Average step length" is a range, not a constant. Adult walking steps typically fall between 60 and 85 cm, with most people near 70–76 cm. The figure depends on height, speed, terrain and footwear, and it changes within a single walk as you speed up or tire.
The most useful single predictor is height. A common rule of thumb is 0.415 times height for men and 0.413 times height for women, with both measurements in the same unit. For a 170 cm adult that is about 70 cm; for 180 cm, about 75 cm.
A height table
| Height | Walking step, men | Walking step, women |
|---|---|---|
| 150 cm | 62 cm | 62 cm |
| 155 cm | 64 cm | 64 cm |
| 160 cm | 66 cm | 66 cm |
| 165 cm | 68 cm | 68 cm |
| 170 cm | 71 cm | 70 cm |
| 175 cm | 73 cm | 72 cm |
| 180 cm | 75 cm | 74 cm |
| 185 cm | 77 cm | 76 cm |
| 190 cm | 79 cm | 78 cm |
| 195 cm | 81 cm | 81 cm |
The values are rounded to the nearest centimetre. They describe a comfortable walk on flat ground, not a race or a hike. A running step is longer: roughly 1.0–1.2 m at an easy pace, and more at speed.
Measure your own in two minutes
- Find a flat, straight stretch and mark a start line.
- Walk ten normal steps, starting with the same foot each time, and mark where the tenth step lands.
- Measure the distance between the lines and divide by ten.
- Repeat three times and average the results. A single measurement is easily off by 5%.
If you use a 20-step course, divide by twenty. The longer the course, the smaller the effect of the start and stop. Do not march or count out loud in an exaggerated way; measure the walk you actually do.
Why running is different
Running lengthens the step and shortens the time on the ground. A running step at an easy pace is often around 1.0–1.2 m, but the term is ambiguous: some watches call two steps a "stride", so their number can be double what a walker means by a step. When comparing figures, check whether the source counts one step or two.
Cadence is the other half of the picture. Speed is step length times steps per minute. Two runners at the same pace can have very different combinations: a longer step at a lower cadence, or a shorter step at a higher cadence. Neither is automatically better; the useful question is which one you can sustain.
Pedometers and phones
A pedometer counts accelerations that look like steps. It is reasonably good at counting and poor at distance, because distance needs a step length it cannot see. Most phones and watches estimate that length from your height and sex, then adjust it with GPS when available. Without GPS, a 10% distance error is normal; with a weak GPS signal, the error can be worse.
Use the step count, measure the distance once. If you walk the same route regularly, measure it once and divide by the steps you took. That personal ratio is more accurate than any height formula, and it takes one walk to obtain.
What the number is good for
- Comparing your own days. The same person on the same route has a stable step length, so the step count tracks distance well.
- Setting a target. A 7,000-step day is about 5 km at 70 cm; a 10,000-step day is about 7 km. The target is a proxy for activity, not a distance contract.
- Estimating a walk. For a route of known length, dividing by a plausible step length gives a step count within about 10%.
It is not good for measuring a route precisely, comparing two people's exercise, or converting a step target into calories. Calories depend on body mass, speed and terrain, and the step count is only one input.
