Mount Fuji vs Mount Kosciuszko
Mount Fuji (3,776 m) is 1.69× the size of Mount Kosciuszko (2,228 m).
Mount Kosciuszko is 59% of the height of Mount Fuji. The gap between them is 1,548 m (5,079 ft).
The comparison in numbers
| Thing | Size | In feet | Measured as |
|---|---|---|---|
| Mount Fuji | 3,776 m | 12,388 ft | elevation |
| Mount Kosciuszko | 2,228 m | 7,310 ft | elevation |
What the scale shows
Mount Fuji (3,776 m) is 1.69× the size of Mount Kosciuszko (2,228 m). The gap between them is 1,548 m (5,079 ft). Both are mountains, so the figures describe the same kind of thing.
Draw both on one baseline and the smaller one fills 59% 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 Fuji is its elevation (summit elevation above sea level). The figure for Mount Kosciuszko is its elevation (summit elevation above sea level).
Crossing them
At a jet's 900 km/h, Mount Fuji's 3,776 m would take 15 seconds and Mount Kosciuszko's 2,228 m would take 8.9 seconds.
In people: Mount Fuji is 2,221 adults of 1.7 m tall, Mount Kosciuszko is 1,310.6. By size Mount Fuji is 8th of the 10 mountains on this site and Mount Kosciuszko is 9th, so 1 place separates them in the ranking.
How to read these two figures
Before trusting any comparison, check what each number measures. Mount Fuji is given as an elevation, summit elevation above sea level. Mount Kosciuszko 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 Fuji is number 24 from the top and Mount Kosciuszko is number 25. 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 1.69× is easy to picture, but area and volume grow faster than length. If two objects had exactly the same shape, Mount Fuji would have about 2.87× the surface or footprint of Mount Kosciuszko, and about 4.87× 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. Mount Kosciuszko is drawn 59% as tall as Mount Fuji, but the equivalent share of footprint would be only 34.8%, 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 Fuji in 6.3 minutes and Mount Kosciuszko in 3.7 minutes. Sound, at about 343 m/s in air, takes 11 seconds for the larger and 6.5 seconds for the smaller. A jet cruising at 900 km/h needs 15 seconds and 8.9 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 1.69× ratio as the sizes.
The same figures in other units
Mount Fuji measures 3,776 m, which is 12,388 ft or 2.35 miles. Mount Kosciuszko measures 2,228 m, which is 7,310 ft or 1.38 miles.
The difference between them is 1,548 m (5,079 ft). In kilometres the smaller one is 2.23 against 3.78, so the 1.69× ratio holds in every unit; only the numbers on the ruler change.
Questions people ask about this pair
Which is bigger, Mount Fuji or Mount Kosciuszko?
Mount Fuji is bigger. At 3,776 m it is 1.69× the size of Mount Kosciuszko, which is 2,228 m.
How many times does Mount Kosciuszko fit along Mount Fuji?
Less than twice: Mount Kosciuszko is 59% of the size of Mount Fuji, so one fits with 1,548 m to spare.
Are the two figures measured the same way?
Yes in kind: both are elevation figures. Mount Fuji is summit elevation above sea level; Mount Kosciuszko is summit elevation above sea level.
How does the gap look in people?
Taking an adult of 1.7 m, Mount Fuji is about 2,221 people tall and Mount Kosciuszko is about 1,310.6. The gap of 1,548 m is 911 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.
