Zoom out from an average adult to a giant cruise ship

A giant cruise ship is too big to show next to an average adult in one picture, so here it is in 3 steps. Each step is drawn to its own scale and zooms out from the step before.

  1. Step 1 of 3 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 3 Megalodon → Gateway Arch

    The Gateway Arch is about 7.9–13 times as tall as a megalodon is long.

  3. Step 3 of 3 Gateway Arch → Cruise ship

    A giant cruise ship is about 1.9 times as long as the Gateway Arch is tall.

About the giant cruise ship

Legend of the Seas, the third Icon-class ship built by Meyer Turku in Finland for Royal Caribbean, is one of the largest cruise ships ever built. The shipyard lists it as 365 m long, with a gross tonnage of 250,800 and room for 5,610 passengers. Gross tonnage measures a ship's enclosed volume, not its weight.

  • Meyer Turku lists Legend of the Seas at 250,800 gross tonnage and 5,610 passengers; the builder says Icon Class ships have room for around 7,600 passengers at full capacity. [1]

How many fit?

  • ≈ 220 × Human · height lined up end to end match the Cruise ship · length
  • ≈ 1.9 × Gateway Arch · maximum height lined up end to end match the Cruise ship · 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

  • 220× A giant cruise ship is about 220 times as long as an average adult is tall. See side by side
  • 1.9× A giant cruise ship is about 1.9 times as long as the Gateway Arch is tall. See side by side
  • 1.4× A giant cruise ship is about 1.4 times as long as the Titanic. See side by side
  • 1.6× A giant cruise ship is about 1.6 times as long as the Hoover Dam is tall. See side by side
  • 1/1.5 One World Trade Center is about 1.5 times as tall as a giant cruise ship is long. See side by side
  • 1/2.3 The Burj Khalifa is about 2.3 times as tall as a giant cruise ship is long. See side by side

Factors compare the length of a giant cruise ship 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

  • Cruise ships vary widely in size. This page uses one of the largest as an example.
  • The drawing is scaled to the 365 m length; its height is illustrative.
