The short answer: 10,000 steps is roughly 6 to 8 km (about 4 to 5 miles), depending mainly on your height, and takes about 77 to 100 minutes of walking at a cadence of 100 to 130 steps a minute. For a person about 173 cm (5'8") tall it's around 7.2 km (4.5 miles). These are estimates; your own number can be checked in a few minutes with a known distance.
Distance by height
Step length depends mostly on height. Pedometers and apps typically estimate it as about 0.413 times height for women and 0.415 for men, and the table uses 0.414. That is a convention rather than a measurement. In a 2025 study of 313 healthy adults reported in Sensors, mean step length ran from 0.62 m in people 141 to 150 cm tall to 0.91 m in those 191 to 200 cm, which is a ratio of roughly 0.41 to 0.47, so individual results vary, and a faster pace usually lengthens the step.
| Height | Estimated step length | 10,000 steps in miles | 10,000 steps in km |
|---|---|---|---|
| 5'0" (152 cm) | 63 cm | 3.9 | 6.3 |
| 5'4" (163 cm) | 67 cm | 4.2 | 6.7 |
| 5'8" (173 cm) | 72 cm | 4.5 | 7.2 |
| 6'0" (183 cm) | 76 cm | 4.7 | 7.6 |
| 6'4" (193 cm) | 80 cm | 5.0 | 8.0 |
So a shorter person covers around 3.9 miles in 10,000 steps and a taller person about 5 miles. The average figure on the earlier page, 4.4 miles or 7.1 km, matches a person about 170 cm tall at an everyday pace.
How long does it take?
The earlier page timed 10,000 steps by walking speed (for example "about 85 minutes at 3 mph"), which depends on step length. Cadence is more direct. The CADENCE-Adults research (Tudor-Locke and colleagues) found that about 100 steps a minute is moderate-intensity walking (3 METs) and about 130 is vigorous (6 METs), with each extra 10 steps a minute adding about 1 MET. Time for 10,000 steps is then just 10,000 divided by your cadence.
| Steps per minute | METs (approx.) | Intensity | Time for 10,000 steps |
|---|---|---|---|
| 100 | 3 | Moderate | 100 min |
| 110 | 4 | Moderate to brisk | 91 min |
| 120 | 5 | Brisk | 83 min |
| 130 | 6 | Vigorous | 77 min |
Most people don't walk 10,000 steps in one go; they accumulate them across the day. How to walk 10,000 steps covers that.
How many calories?
The earlier page said 300 to 500 calories. Using the standard method (calories equal METs times body weight in kilograms times hours), a 3 mph walk rated 3.5 METs, and a 170 cm step length, the figures are below, with the extra energy above what you'd burn sitting in brackets. They are estimates; our other pages use a slightly longer step and so give about 10% higher totals. See calories burned walking for the method.
| Body weight | Calories for 10,000 steps at about 3 mph (extra above resting) |
|---|---|
| 55 kg (121 lb) | 280 (200) |
| 70 kg (154 lb) | 360 (260) |
| 85 kg (187 lb) | 440 (310) |
| 100 kg (220 lb) | 510 (370) |
Where did 10,000 steps come from?
It was not a research finding. In 1965, after the 1964 Tokyo Olympics had made fitness fashionable in Japan, the clock and instrument maker Yamasa Tokei Keiki sold a pedometer called the manpo-kei, which translates as "10,000 steps meter." The round number stuck. We've taken this from secondary sources citing Catrine Tudor-Locke's history of step counting, rather than from the company's own records.
Modern research doesn't treat 10,000 as a threshold. A 2025 review in The Lancet Public Health (Ding and colleagues) found that about 7,000 steps a day went with 47% lower all-cause mortality than 2,000, and the benefit levels off with diminishing returns beyond that; the 2019 study of older women (Lee and colleagues) found benefit levelling off near 7,500. See how many steps you need and the 4,400 steps study. We removed the earlier page's claim that 10,000 steps "delivers excellent health benefits for weight loss," because weight loss from walking is modest; see how many steps to lose weight.
Perspective
On a standard 400 m running track, 7 km is about 17 or 18 laps (simple arithmetic). We've dropped the earlier page's comparison with football fields, which depends on the pitch.

Correction note: an earlier version of this page gave 75 to 90 minutes and a pace-based time table, 300 to 500 calories, a football-field comparison, and said 10,000 steps delivers excellent benefits for weight loss. The height table was consistent with the pedometer convention and is kept, now labelled as an estimate. We could not support the football-field and weight-loss claims, and rebuilt the time table from cadence data and the calorie table from published MET values. The step-length convention and the origin of the manpo-kei are taken from calculator and secondary pages, not primary records. The calorie figures are our own arithmetic and are approximate.
