Stride length is mostly a function of leg length, which is mostly a function of overall height. Pedometers and watches that don't ask for height end up using a default ~0.7 m stride that's wrong for tall and short people both. Knowing your real stride lets you convert steps to distance accurately — and tells you something useful about gait efficiency too.
Stride-length formulas
Common heuristics: stride (m) ≈ height (cm) × 0.413 (women) or × 0.415 (men). Slightly different across athletic literature: 0.43 for casual walking, 0.415 for fast walking. So a 175 cm man has a ~0.73 m stride; a 160 cm woman has ~0.66 m.
Measuring directly (more accurate)
On a track or any 100 m straight: walk normally, count steps, divide. Stride = 100 ÷ steps. Average over two passes. This is more accurate than the height formula because gait, hip width, and walking style all factor in.
Why stride matters for step counts
Two people walking 5 km hit very different step totals. At 0.65 m stride (short adult): ~7,700 steps. At 0.80 m (tall adult): ~6,250. Same distance, ~25% step difference. If you're comparing step counts to friends — especially across heights — you're comparing apples to slightly-different-sized apples.
Stride and pace
Walking faster doesn't just mean more steps — it usually means longer stride too. From 4 km/h to 6 km/h, stride lengthens about 15%. So at faster pace, you cover more distance per step. Fitness watches calibrated for one pace will under- or over-count distance at other paces unless they have GPS to correct.
FAQ
- How does height affect calorie burn per step?
- Negligibly directly — calorie burn scales mostly with body mass and pace. But taller people walking the same distance take fewer steps and burn slightly more per step, which roughly cancels out at the same total distance.
- Should kids use a different formula?
- Yes — kids' proportions differ. Use the directly-measured method for anyone under ~140 cm.
