Zoom out from an average adult to the Leaning Tower of Pisa

The Leaning Tower of Pisa is too big to show next to an average adult in one picture, so here it is in 2 steps. Each step is drawn to its own scale and zooms out from the step before.

  1. Step 1 of 2 Human → Megalodon

    A megalodon is about 8.6–15 times as long as an average adult is tall.

  2. Step 2 of 2 Megalodon → Leaning Tower of Pisa

    The Leaning Tower of Pisa is about 2.4–3.9 times as tall as a megalodon is long.

About the Leaning Tower of Pisa

The Leaning Tower is the free-standing marble bell tower of Pisa Cathedral, begun in 1173 and finished in the 14th century after long pauses. Its foundations began sinking unevenly into the soft ground while it was still being built, giving it a lean that reached 5.5 degrees in the late 20th century. After stabilisation work between 1990 and 2001, the Opera della Primaziale Pisana gives its current tilt as about 5.115 degrees, its height as 58.36 m and its weight as 14,453 tonnes.

  • Its current inclination is about 5.115 degrees. [1]
  • In the late 20th century the tower leaned 5.5 degrees, about 4.5 m (15 ft) off the vertical; soil was removed from under the foundations until 2001, and by 2008 the lean had improved by 48 cm (19 in) in total. [2]
  • Construction stopped for almost a century after the first three of its eight storeys were built, which let the ground settle and probably saved it from collapsing early. [2]
  • It holds seven bells, one for each musical note; the largest, cast in 1655, weighs three and a half tonnes. [1]

How many fit?

  • ≈ 35 × Human · height lined up end to end match the Leaning Tower of Pisa · height
  • ≈ 170,000 × Human · body mass on the scales weigh as much as Leaning Tower of Pisa · weight
  • ≈ 2 × Basketball court (NBA) · length lined up end to end match the Leaning Tower of Pisa · height

Counts divide one sourced figure by another. "End to end" uses each object's main measurement; weight and volume rows appear only when both figures are sourced.

Factors compare the height of the Leaning Tower of Pisa with each object’s own main measurement (height for a human). Where a size varies, the factor is given as a range.

Notes on these figures

  • Separate heights for the low and high sides of the tower could not be confirmed from a fetched official page, so only the single official height of 58.36 m is stored.
  • Step counts differ between sources: the Opera della Primaziale Pisana lists 273 steps and Britannica says 294 steps lead to the bell chamber, so no step count is used.
  • Britannica gives the originally planned height as 56 m (185 ft), which differs from the official measured height.
