Zoom out from an average adult to an Olympic swimming pool

An Olympic swimming pool 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.

    Step 1: Human and Megalodon at the same scale.

  2. Step 2 of 2 Megalodon → Olympic swimming pool

    An Olympic swimming pool is about 2.1–3.3 times as long as a megalodon.

About the Olympic swimming pool

An Olympic swimming pool is 50 metres long between the electronic touch panels at each end, and World Aquatics allows only 1 cm of extra length and none short. Pools used at the Olympic Games must be at least 25 m wide, enough for eight 2.5 m lanes plus a 2.5 m buffer space on each side. World Aquatics' current certification rules call for a water depth of at least 2.5 m, rising to 3 m when the pool is shared with artistic swimming.

  • Without touch panels, the wall-to-wall distance of a 50 m pool must be between 50.020 m and 50.030 m so that the panels can be fitted and still leave 50.000 m. [1]
  • Olympic Games pools have 8 lanes, while World Championships pools have 10. [2]
  • The earlier 2021-2025 Facilities Rules set the Olympic pool minimum depth at 2 m, with 3 m recommended for multi-discipline use. [2]

How many fit?

  • ≈ 30 × Human · height lined up end to end match the Olympic swimming pool · length
  • ≈ 1.7 × Basketball court (NBA) · length lined up end to end match the Olympic swimming pool · length

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.

How it compares

  • 30× An Olympic swimming pool is about 30 times as long as an average adult is tall. See side by side
  • 1.7× An Olympic swimming pool is about 1.7 times as long as an NBA basketball court. See side by side
  • 1.3× An Olympic swimming pool is about 1.3 times as long as a Boeing 737. See side by side
  • 1/1.2 The Leaning Tower of Pisa is about 1.2 times as tall as an Olympic swimming pool is long. See side by side
  • 1/1.9 The Statue of Liberty is about 1.9 times as tall as an Olympic swimming pool is long. See side by side
  • 1/2.5 SpaceX's Starship is about 2.5 times as tall as an Olympic swimming pool is long. See side by side

Factors compare the length of an Olympic swimming pool 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

  • Width and depth are minimums for Olympic Games pools; real pools can be wider or deeper.
  • No official source found gives a water volume, so none is listed.
