Concorde vs Leaning Tower of Pisa
Concorde (61.7 m) is 1.1× the size of Leaning Tower of Pisa (56 m).
Leaning Tower of Pisa is 91% of the height of Concorde. The gap between them is 5.66 m (18.6 ft).
The comparison in numbers
| Thing | Size | In feet | Measured as |
|---|---|---|---|
| Concorde | 61.7 m | 202 ft | length |
| Leaning Tower of Pisa | 56 m | 184 ft | height |
What the scale shows
Concorde (61.7 m) is 1.1× the size of Leaning Tower of Pisa (56 m). The gap between them is 5.66 m (18.6 ft). One is among the vehicles & ships and the other among the buildings & towers, so the figures are standing in for different kinds of size — read the basis below.
Draw both on one baseline and the smaller one fills 91% 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 Concorde is its length (overall length). The figure for Leaning Tower of Pisa is its height (average height of the tower).
Crossing them
Walking pace is 1.4 m/s, so crossing Concorde's 61.7 m takes 44 seconds and Leaning Tower of Pisa's 56 m takes 40 seconds.
In people: Concorde is 36 adults of 1.7 m tall, Leaning Tower of Pisa is 32.9. By size Concorde is 11th of the 14 vehicles & ships on this site, while Leaning Tower of Pisa is 22nd of the 23 buildings & towers.
How to read these two figures
Before trusting any comparison, check what each number measures. The Concorde is given as a length, overall length. The Leaning Tower of Pisa is given as a height, average height of the tower. One is a length and the other is a height, so the drawing stands them side by side by convention: everything is stood upright on a single baseline so one scale can hold. That is a fair way to compare overall extent, not a claim that the two are oriented the same way in real life.
Vehicles are listed by overall length. Rockets are the exception and are given as full stack height standing on the pad. Everything is drawn standing upright so one scale holds. Building heights depend on the rule used: architectural height counts spires but not antennas, tip height counts everything. The basis is named with each figure.
Where the pair sits among all the sizes here
Across all 86 things on this site, the Concorde is number 58 from the top and the Leaning Tower of Pisa is number 59. 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 lower third of the list.
What the length ratio hides
A length ratio of 1.1× is easy to picture, but area and volume grow faster than length. If two objects had exactly the same shape, the Concorde would have about 1.21× the surface or footprint of the Leaning Tower of Pisa, and about 1.33× 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. The Leaning Tower of Pisa is drawn 91% as tall as the Concorde, but the equivalent share of footprint would be only 82.5%, 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 the Concorde in 6.2 seconds and the Leaning Tower of Pisa in 5.6 seconds. Sound, at about 343 m/s in air, takes 180 milliseconds for the larger and 163 milliseconds for the smaller. A jet cruising at 900 km/h needs 247 milliseconds and 224 milliseconds.
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 1.1× ratio as the sizes.
The same figures in other units
The Concorde measures 61.7 m, which is 202 ft or 67.4 yards. The Leaning Tower of Pisa measures 56 m, which is 184 ft.
The difference between them is 5.66 m (18.6 ft). In metres the smaller one is 56 against 61.66, so the 1.1× ratio holds in every unit; only the numbers on the ruler change.
Questions people ask about this pair
Which is bigger, the Concorde or the Leaning Tower of Pisa?
The Concorde is bigger. At 61.7 m it is 1.1× the size of the Leaning Tower of Pisa, which is 56 m.
How many times does the Leaning Tower of Pisa fit along the Concorde?
Less than twice: the Leaning Tower of Pisa is 91% of the size of the Concorde, so one fits with 5.66 m to spare.
Are the two figures measured the same way?
No. The Concorde is a length (overall length) and the Leaning Tower of Pisa is a height (average height of the tower), so read the comparison as overall extent.
How does the gap look in people?
Taking an adult of 1.7 m, the Concorde is about 36 people tall and the Leaning Tower of Pisa is about 32.9. The gap of 5.66 m is 3.3 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.
