Steps to the World's Highest Peaks

Mountains are measured vertically and walked horizontally, so converting a summit height into steps is a thought experiment rather than a route. What it gives you is a sense of scale: how much walking equals how much mountain.

The peaks as steps

Using an average adult walking stride of 0.75 metres, here is each major peak's full height expressed as horizontal walking steps.

Peak	Height	Steps (as distance)
Everest	8,849 m	11,800
K2	8,611 m	11,480
Kangchenjunga	8,586 m	11,450
Denali	6,190 m	8,250
Kilimanjaro	5,895 m	7,860
Elbrus	5,642 m	7,520
Mont Blanc	4,808 m	6,410
Matterhorn	4,478 m	5,970
Fuji	3,776 m	5,030
Ben Nevis	1,345 m	1,790

The headline result is deflating in a useful way. Everest's entire height, laid flat, is about 11,800 steps — barely above a standard daily target. A reasonably active person covers the height of Everest, horizontally, most days without noticing.

The Seven Summits

The highest peak on each continent totals roughly 43,313 metres of vertical height: Everest, Aconcagua, Denali, Kilimanjaro, Elbrus, Vinson and either Puncak Jaya or Kosciuszko depending on which list you use. Laid flat, that is about 57,750 steps, or 26.9 miles — almost exactly a marathon.

That coincidence is the most quotable fact on this page: the combined height of the highest mountain on every continent is roughly one marathon.

Why climbing steps are not walking steps

The comparison above measures distance, not effort, and the gap between those two is enormous.

Walking on the flat costs roughly 0.5 kilocalories per kilogram per kilometre. Ascending costs far more, and the accepted approximation is that lifting your body one metre vertically requires energy comparable to walking somewhere between six and nine metres horizontally. On that basis, Everest's 8,849 metres of ascent is energetically equivalent to walking 55 to 80 kilometres on flat ground.

Then there is the air. Above 8,000 metres, in what climbers call the death zone, atmospheric pressure falls to roughly a third of sea-level pressure, and the body cannot acclimatise — it deteriorates continuously regardless of fitness. Climbers in that zone commonly report needing several full breaths per step. The step count is unchanged; the cost per step is not.

Stride length also collapses on steep ground. On the fixed ropes of the Lhotse Face or the Hillary Step, effective stride can drop below 0.3 metres, which more than doubles the number of steps required to cover the same vertical distance.

A more honest comparison

If you want a number that reflects the real work, the useful conversion is not distance but ascent. Climbing a standard building staircase covers about 0.17 metres of vertical rise per step. On that basis:

• Everest is about 52,000 stair-steps of vertical gain.
• Kilimanjaro is about 34,700.
• Ben Nevis is about 7,900.
• The Empire State Building's 1,576 stairs are about 268 metres — roughly 3 per cent of Everest.

The tallest building stair climbs in the world therefore represent a few per cent of a major peak, which is a fairer reflection of the difference than the flat-distance comparison. Even that ignores altitude, cold, load and terrain, which is where the actual difficulty lives.

Your step count, by height

Step length varies with height by more than 25 per cent across the adult range, so the single figure at the top of this page will not be right for everyone. Here is the same distance for a range of heights, using the standard estimate of 0.414 × height.

Your height	Est. step length	Steps for this route
1.55 m	0.64 m	67,432
1.65 m	0.68 m	63,384
1.75 m	0.72 m	59,712
1.85 m	0.77 m	56,516
1.95 m	0.81 m	53,645

These are estimates. If you want a figure that matches your own gait, our guide to measuring your stride length takes about five minutes.

Common questions

How many steps is the height of Mount Everest?

Laid flat, Everest's 8,849 metres is about 11,800 walking steps. As vertical climbing on standard stairs, it is closer to 52,000 stair-steps.

What is the combined height of the Seven Summits in steps?

About 57,750 steps, or 26.9 miles — close to the distance of a marathon.

Why is climbing so much harder than the step count suggests?

Lifting your body vertically costs roughly six to nine times the energy of moving the same distance horizontally, before accounting for altitude, cold, terrain and carried weight.
