10,000 steps a day: where the number came from and what it adds up to

Where did 10,000 steps a day come from?

Not from a lab. The figure is usually traced to a Japanese pedometer sold in the 1960s under a name that means "10,000-step meter". It was a good name: round, memorable and a little ambitious. It stuck, and over the years it became the default goal on step counters all over the world.

That doesn't make it wrong, just arbitrary. 10,000 is a perfectly reasonable target for many people. But a round number was never meant to be the line between "healthy" and "not", and treating it as a pass mark can make a 7,000-step day feel like a failure when it isn't.

What does research say about daily steps?

The most useful answer comes from Paluch and colleagues (Lancet Public Health, 2022), who pooled data from 15 cohorts of adults. In plain words:

• More steps were linked with a lower risk of dying from any cause over the study periods, compared with people taking the fewest steps.
• The benefit levelled off at about 6,000–8,000 steps a day for adults over 60, and at about 8,000–10,000 for younger adults.
• These are associations from observational studies. They show a pattern across many people, not a promise for any one person.

In short, days that fall short of 10,000 still count.

Steps aren't the only way to be active, either. The WHO recommends 150–300 minutes of moderate activity a week for adults, and brisk walking is one of the easiest ways to get there. Brisk means you can still talk, but not sing.

How many km is 10,000 steps?

It depends on your step length, which changes with your height and pace. For many adults a walking step is about 0.7 to 0.8 m, so 10,000 steps is roughly 7 to 8 km, or about 4.3 to 5 miles. The other way round, 1 km takes about 1,250 to 1,430 steps.

Times assume an everyday pace of roughly 85 to 110 steps a minute. So 10,000 steps is about 1.5 to 2 hours of walking in total, but almost nobody does it in one go: it builds up through the day. A brisk walker covers the same steps in less time; a stroll with stops takes longer. Even three 10-minute walks scattered through a day come to roughly 2,550–3,300 steps at that pace.

How many calories do 10,000 steps use?

Here the honest answer is a range. The energy each step uses depends mostly on your body weight and your pace, plus hills, terrain and anything you carry. For many adults, 10,000 steps comes to very roughly 300 to 500 kcal: nearer the lower end for lighter people and gentle strolls, nearer the upper end for heavier people and brisk walks. That's roughly 3 to 5 kcal per 100 steps.

Two caveats keep this number in proportion:

• Part of it is energy your body would use anyway, even sitting still, so the extra is smaller than the total.
• Watches and apps estimate it in different ways, so two devices can disagree a lot about the same walk.

So treat your step count as a mirror of how much you moved, not as a calorie machine.

For an estimate with your own weight, the steps to calories calculator does the maths:

In Doydum, your daily calorie target comes from your plan, which already includes the activity level you chose; your steps have their own goal on the farm.

Is 10,000 steps a day enough, or too much?

For many people it's a fine target, and for some it's a stretch. Going by the research above, the right number for you depends on where you're starting:

• If you average 3,000–4,000 steps, jumping straight to 10,000 is a big leap. Add one short walk a day and build up week by week.
• If you're over 60, the 2022 analysis found the benefit levelling off around 6,000–8,000, which makes that range a solid aim.
• If you're already active, 10,000 or more is a nice daily rhythm, and brisk walks count towards the WHO's weekly minutes.
• If you sit for work, a few minutes on your feet every hour adds steps and breaks up long stretches of sitting.

Whatever the number, steady beats heroic. Walking 7,000 steps every day adds up to more than one 15,000-step Sunday after a quiet week. If a health condition makes walking hard, ask your doctor what kind of movement suits you.

Does walking 10,000 steps a day help with weight loss?

Walking raises the energy you use, so more steps can help a calorie deficit along. But the scale follows the whole picture over weeks, and most of that picture is what you eat. Walking doesn't promise any number on the scale, and it doesn't need to: the research above links more steps with a lower risk of death, which is reason enough to walk.

That's why it helps to keep the two apart. Walk for the walk, and set your food from your plan. Doydum works the same way: steps lay stones on the farm path, and Doy never suggests earning food with exercise. If you're working on a deficit, our guide to calorie deficits explains how the plan sizes one.

How to fit more steps into your day

• Get off the bus or metro one stop early and walk the rest.
• Take a 15-minute loop at lunch: at an everyday pace that's roughly 1,300–1,650 steps.
• Walk after dinner. An evening stroll is also a good time to catch up with someone.
• Take phone calls on your feet.
• Choose the stairs when it's only a floor or two.

Each of these adds anything from a few hundred to a couple of thousand steps. Together they can turn an ordinary day into a surprisingly long walk, and on a hot day, bring water: our guide on how much water to drink has the details.

How Doydum picks your step target

Doydum suggests a daily target from the activity level in your plan, and you can set anything from 2,000 to 30,000:

Steps come from your iPhone's motion sensor and are read when you open the app. Then they turn into something you can see: every 1,000 steps lays a stone on the farm path, and reaching your target opens the gate. On a day when meals, water and steps are all done, a sunflower appears along the fence. Explore it all on Doy's farm, or see the steps feature on our home page.

One honest catch: your iPhone can only count the steps it's with you for. Leave it on your desk during a walk round the office and those steps won't show. Swimming and cycling barely register as steps at all, so on those days your count undersells how active you were.
