That's about 3 h 5 min of walking, and 620 to 1,030 active calories for adults from 150 to 250 lb.
How many miles is 20,000 steps for your height?
Taller people take longer steps, so the same count covers more ground. A faster walk makes every step longer too, which is why pace changes the answer more than height does. In kilometers, 20,000 steps is about 14.8 km on a walk and 11.6 km through the day.
| Height | Through the day2 mph | On a walk3 mph | On a fast walk4 mph |
|---|---|---|---|
| 5 ft 0 in | 6.2 mi | 7.9 mi | 9.2 mi |
| 5 ft 4 in | 6.6 mi | 8.4 mi | 9.8 mi |
| 5 ft 8 in | 7.0 mi | 8.9 mi | 10.5 mi |
| 6 ft 0 in | 7.4 mi | 9.4 mi | 11.1 mi |
| 6 ft 4 in | 7.8 mi | 10.0 mi | 11.7 mi |
How long does it take to walk 20,000 steps?
About 3 h 5 min at 3 mph, and 2 h 40 min on a fast walk at 4 mph. Each extra 5,000 steps adds about 45 minutes at 3 mph.
How many calories does 20,000 steps burn?
| Weight | Through the day2 mph | On a walk3 mph | On a fast walk4 mph |
|---|---|---|---|
| 150 lb | 480 | 620 | 800 |
| 200 lb | 640 | 820 | 1,070 |
| 250 lb | 800 | 1,030 | 1,340 |
Those are active calories, what the walk adds to what your body burns at rest anyway. Counting rest, the total for someone who weighs 200 lb is about 1,110 on a walk and 990 through the day. If you track calories, add only the active part. Your daily burn already counts rest, so the total would count it twice.
Is 20,000 steps a lot?
Yes, a lot. US adults average about 8,800 steps a day on a wrist tracker4, so 20,000 is about 2.5 times that. It’s a long day on your feet, the kind that usually takes a long walk on top of everything else. On a walk at 3 mph, 20,000 steps is more than a 10K.
Why do other sites say 10.0 miles?
Many sites divide by 2,000 steps a mile. That rule fits a fast walk at 4 mph by someone about 5 ft 5 in tall. At 3 mph your steps are shorter, so 20,000 of them cover about 9.2 miles, and about 7.2 through the day. The calculator shows how many steps a mile takes at each height and pace.
Your own numbers
The steps to calories calculator works out the miles, time, and calories for your height, weight, and pace. Or see 18,000 steps and 25,000 steps.
In Fit Shapes there's no math to do. It doesn't count steps. Your phone or watch already records active energy in Apple Health or Health Connect, which covers your walking and everything else you do, and Fit Shapes adds that to your resting burn. Then once a week, Adaptive Targets compares the whole burn with what you ate and how your weight moved.
