How many km is 10,000 steps? It depends on your height.
Most answers online give you one number for everybody. Your stride is set by how tall you are, so put your height in and get the figure that’s actually yours — steps to kilometres, or kilometres to steps.

The quick answers
These use an average woman’s stride — about 1,480 steps per kilometre, based on a height of 163 cm. Taller walkers need fewer steps, shorter walkers a few more, and the calculator above adjusts for you.
Steps per km by height
Step length — the distance from one heel landing to the next — scales almost exactly with height. That’s why a 155 cm walker and a 185 cm walker can finish the same kilometre several hundred steps apart, and why a single “average” answer is never quite right for anyone. Find your height below.
| Height | Step length | Steps per km (female) | Steps per km (male) |
|---|---|---|---|
| 150 cm | 61.9 cm | 1,610 | 1,610 |
| 155 cm | 64.0 cm | 1,560 | 1,550 |
| 160 cm | 66.1 cm | 1,510 | 1,510 |
| 165 cm | 68.1 cm | 1,470 | 1,460 |
| 170 cm | 70.2 cm | 1,420 | 1,420 |
| 175 cm | 72.3 cm | 1,380 | 1,380 |
| 180 cm | 74.3 cm | 1,350 | 1,340 |
| 185 cm | 76.4 cm | 1,310 | 1,300 |
| 190 cm | 78.5 cm | 1,270 | 1,270 |
Rounded to the nearest 10 steps. The female and male columns differ only by the stride factor used (0.413 vs 0.415 of height); your own measured stride beats both.
Is 10,000 steps really 7 km?
Close enough for a rule of thumb, a little generous for most women. At 163 cm, 10,000 steps works out at about 6.7 km; at 175 cm it’s nearer 7.2 km. The often-quoted “10,000 steps = 8 km” assumes a long stride and a brisk pace, which is why your fitness app may show a shorter distance than you expected.
The 10,000 figure itself was never a scientific target. A Japanese pedometer sold around the 1964 Tokyo Olympics was named the manpo-kei — “10,000-step meter” — and the number stuck because it’s memorable. Research since has been broadly supportive but far less strict about the exact figure: in studies of older women, the drop in mortality risk climbs steeply from around 4,000 steps a day and largely levels off near 7,500. In kilometres, that’s roughly 2.7 km to 5 km of walking a day — a target most people can genuinely reach.
| Steps | Kilometres | Miles | Time at 5 km/h |
|---|---|---|---|
| 2,000 | 1.35 | 0.84 | 16 min |
| 3,000 | 2.03 | 1.26 | 24 min |
| 5,000 | 3.38 | 2.10 | 41 min |
| 6,000 | 4.05 | 2.52 | 49 min |
| 7,500 | 5.07 | 3.15 | 1h 1m |
| 8,000 | 5.41 | 3.36 | 1h 5m |
| 10,000 | 6.76 | 4.20 | 1h 21m |
| 12,000 | 8.11 | 5.04 | 1h 37m |
| 15,000 | 10.14 | 6.30 | 2h 2m |
| 20,000 | 13.51 | 8.40 | 2h 42m |
How many steps in 5 km — and how long does it take?
A 5 km walk is about 7,400 steps for an average-height woman, or roughly 6,700 for someone taller. At a steady 5 km/h — the pace most people settle into when walking with purpose — it takes an hour. Walk it gently at 4 km/h and you’re looking at 75 minutes; stride out at 6 km/h and it’s 50. Distance is set by your legs, but the clock is set by your pace.
| Distance | Steps | Time at 5 km/h |
|---|---|---|
| 1 km | 1,480 | 12 min |
| 2 km | 2,960 | 24 min |
| 3 km | 4,440 | 36 min |
| 5 km | 7,400 | 1h 0m |
| 10 km | 14,800 | 2h 0m |
| Half marathon (21.1 km) | 31,228 | 4h 13m |
How this calculator works
Estimating your step length
The calculator uses the stride factors long used to calibrate pedometers: step length = height × 0.413 for women and height × 0.415 for men. For a 163 cm woman that’s a step length of about 67 cm.
Turning that into steps per kilometre
A kilometre is 100,000 cm, so steps per km = 100,000 ÷ step length in cm — about 1,485 steps in our example. Kilometres are then simply steps ÷ steps per km, and the reverse direction multiplies instead. Miles use 1 km = 0.621371 miles, and the walking-time estimate assumes a steady 5 km/h.
Where the numbers come from
The 0.413 / 0.415 height factors are the standard pedometer-calibration figures reproduced in ACSM’s exercise-prescription guidance and in most public-health step guides. They agree well with measured research: Hoeger and colleagues counted real steps per mile across walking and running speeds and found roughly 1,900–2,200 steps per mile at typical walking speeds — about 1,200–1,400 steps per kilometre — with step counts rising as pace slows.
Why your real number may differ
Pace matters: stroll slowly and your steps shorten, so a kilometre costs you extra steps; walk briskly and it costs fewer. Hills, sand, a heavy bag, sore knees and pushing a buggy all shorten a step too. For a number that’s exactly yours, walk a measured 400 m running track lap, count your steps, and multiply by 2.5.

Frequently asked questions
How many km is 10,000 steps?
About 6.5 to 7.5 km for most adults. A woman of average height (163 cm) covers roughly 6.7 km in 10,000 steps; a taller walker of 178 cm covers about 7.4 km. Enter your height above for your own figure.
How many steps are in 1 km?
Roughly 1,250 to 1,550 steps for most adults walking at a normal pace. An average-height woman takes about 1,480 steps per kilometre; an average-height man about 1,370.
How many steps are in 5 km?
Around 7,400 steps for an average-height woman and about 6,900 for an average-height man — so a 5 km walk covers most of a 10,000-step day on its own. It takes about an hour at a steady 5 km/h.
How many steps a day should I walk?
More than yesterday is a genuinely good answer. Research on older adults suggests benefits climb steeply from about 4,000 steps a day (roughly 2.7 km) and start to level off near 7,500 (about 5 km). You don’t need to hit 10,000 to be getting the benefit.
Does walking pace change how many steps are in a kilometre?
Yes. Walking faster lengthens your step, so a brisk kilometre takes fewer steps than a slow one — the gap can be over 100 steps per kilometre between an amble and a march. This calculator assumes a normal, comfortable pace.
How do I measure my own stride length?
Walk a known distance and divide. One lap of a standard running track is 400 m: count your steps for a lap and multiply by 2.5 to get your true steps per kilometre. Or measure 20 normal steps with a tape measure and divide the distance by 20.
How long does it take to walk 10,000 steps?
About 80 to 100 minutes at a steady 5 km/h — usually spread across a whole day rather than done in one go. Three 25-minute walks will get most people there alongside normal daily movement.
