Mount Kilimanjaro (5,895 m) is 1.23× the size of Mont Blanc (4,805.59 m).
Mont Blanc is 82% of the height of Mount Kilimanjaro. The gap between them is 1,089.41 m (3,574 ft).
The comparison in numbers
| Thing | Size | In feet | Measured as |
|---|---|---|---|
| Mount Kilimanjaro | 5,895 m | 19,341 ft | elevation |
| Mont Blanc | 4,805.59 m | 15,766 ft | elevation |
What the scale shows
Mount Kilimanjaro (5,895 m) is 1.23× the size of Mont Blanc (4,805.59 m). The gap between them is 1,089.41 m (3,574 ft). Both are mountains, so the figures describe the same kind of thing.
Draw both on one baseline and the smaller one fills 82% of the frame while the larger one runs to the top. The two are close enough that the difference is easy to see side by side.

What each figure means
The figure for Mount Kilimanjaro is its elevation (summit elevation above sea level). The figure for Mont Blanc is its elevation (summit elevation above sea level).
Crossing them
At a jet's 900 km/h, Mount Kilimanjaro's 5,895 m would take 24 seconds and Mont Blanc's 4,805.59 m would take 19 seconds.
In people: Mount Kilimanjaro is 3,468 adults of 1.7 m tall, Mont Blanc is 2,826.8. By size Mount Kilimanjaro is 5th of the 10 mountains on this site and Mont Blanc is 6th, so 1 place separates them in the ranking.
How to read these two figures
Before trusting any comparison, check what each number measures. Mount Kilimanjaro is given as an elevation, summit elevation above sea level. Mont Blanc is given as an elevation, summit elevation above sea level. Both are elevation figures, so putting them on one baseline is a like-for-like comparison, although the exact individual or convention still matters.
Elevation is measured from mean sea level to the summit, not from the base of the mountain. Surveys are revised, so a figure here can differ from an older atlas by a few metres.
Where the pair sits among all the sizes here
Across all 86 things on this site, Mount Kilimanjaro is number 21 from the top and Mont Blanc is number 22. No other item falls between them, so in this collection they are direct neighbours.
Because the collection spans 13 mm up to 1,392,700 km, a ratio of 107,130,769,231× from smallest to largest, the position of a pair says a lot: both sit in the upper third of the list.
What the length ratio hides
A length ratio of 1.23× is easy to picture, but area and volume grow faster than length. If two objects had exactly the same shape, Mount Kilimanjaro would have about 1.5× the surface or footprint of Mont Blanc, and about 1.85× the volume. These two are not the same shape, so treat the figures as an upper bound for an imaginary scaled copy, not as a measurement of either one.
The drawing above shows length only. Mont Blanc is drawn 82% as tall as Mount Kilimanjaro, but the equivalent share of footprint would be only 66.5%, which is why the smaller one looks even slighter than the numbers alone suggest.
Time to cross each one
A sprinter holding about 10 m/s covers Mount Kilimanjaro in 9.8 minutes and Mont Blanc in 8 minutes. Sound, at about 343 m/s in air, takes 17 seconds for the larger and 14 seconds for the smaller. A jet cruising at 900 km/h needs 24 seconds and 19 seconds.
These times assume a straight line and constant speed, which no real crossing has, but they turn a number in metres into something the body understands. At any fixed speed the travel times keep the same 1.23× ratio as the sizes.
The same figures in other units
Mount Kilimanjaro measures 5,895 m, which is 19,341 ft or 3.66 miles. Mont Blanc measures 4,805.59 m, which is 15,766 ft or 2.99 miles.
The difference between them is 1,089.41 m (3,574 ft). In kilometres the smaller one is 4.81 against 5.9, so the 1.23× ratio holds in every unit; only the numbers on the ruler change.
Questions people ask about this pair
Which is bigger, Mount Kilimanjaro or Mont Blanc?
Mount Kilimanjaro is bigger. At 5,895 m it is 1.23× the size of Mont Blanc, which is 4,805.59 m.
How many times does Mont Blanc fit along Mount Kilimanjaro?
Less than twice: Mont Blanc is 82% of the size of Mount Kilimanjaro, so one fits with 1,089.41 m to spare.
Are the two figures measured the same way?
Yes in kind: both are elevation figures. Mount Kilimanjaro is summit elevation above sea level; Mont Blanc is summit elevation above sea level.
How does the gap look in people?
Taking an adult of 1.7 m, Mount Kilimanjaro is about 3,468 people tall and Mont Blanc is about 2,826.8. The gap of 1,089.41 m is 641 people.
Where do the numbers come from?
Each item has its own page that names the measurement and links to the Wikipedia article it was taken from. Some figures are rounded, and animals vary from one individual to the next, so treat them as representative values rather than records for every case.
How the sizes are taken. Each figure says what it measures — height, length, diameter or elevation — and for which individual or convention. Everything is drawn standing upright on one baseline so a single scale holds, including things that are long rather than tall. Values come from the linked Wikipedia article for each item.
