# Steps to miles and kilometres calculator > For most adults, 2,100 to 2,500 walking steps make a mile, so 10,000 steps is roughly 4 to 4.7 miles (6.5 to 7.5 km). Your own number depends on your step length, which is close to 41% of your height. Enter your steps, or a distance, and your height. - URL: https://www.getstepup.app/tools/steps-to-miles (the calculator runs there, in the browser, and sends nothing anywhere) - Updated: 2026-10-17 ## How many steps are in a mile? Distance is your steps times the length of one step. A walking step is close to 41% of your height (0.414 is the ratio this tool uses), so someone 170 cm (5 ft 7 in) tall steps about 70 cm, and takes around 2,290 steps to walk a mile, or 1,420 to walk a kilometre. Taller walkers need fewer steps, shorter walkers more. ## How long does the walk take? The distance over your speed. At a moderate 3 mph (4.8 km/h) a mile takes 20 minutes and 5 km a little over an hour; at a brisk 3.5 mph (5.6 km/h), 17 minutes and 54 minutes. The [walking pace](https://www.getstepup.app/tools/walking-pace) of a walk you’ve timed is better than a guess. ## Why does my phone say something different? Steps get shorter when you walk slowly, uphill or in a crowd, and longer when you stride out. Your iPhone measures your real step length as you walk, so over a day it’s usually closer than any formula. For a number of your own, [measure your step](https://www.getstepup.app/tools/stride-length) over a known distance. ## In StepUp StepUp shows today's distance under your steps, from the step length your iPhone measures as you walk. ## Questions ### How far is 10,000 steps? About 7 km, or 4.4 miles, for someone 170 cm tall. Between 6.5 and 7.5 km (4 and 4.7 miles) for most adults. ### How many steps is 5 km? Roughly 6,500 to 7,750 steps, depending on your height: about 7,100 at 170 cm (5 ft 7 in). ### How many steps is a marathon? About 30,000 for a half marathon (21.1 km) and 60,000 for a full one (42.2 km), at an average height. ### Does running change the distance? Yes. Running steps are much longer than walking ones, so this tool, which is for walking, will undercount a run. ## Sources - [CDC: Physical activity guidelines for adults](https://www.cdc.gov/physical-activity-basics/guidelines/adults.html)
