By size · Order from shortest to longest.

  1. A cheetah (body length) 1.2 m

    A cheetah's spine works like a spring, flexing so much that its stride can cover seven metres at full sprint.

  2. A Brachiosaurus (length) 22 m

    It held its neck high like a giraffe, possibly needing a heart of enormous power to pump blood up to its brain.

  3. The Burj Khalifa, Dubai 828 m

    It is so tall that people on the ground floor can watch the sunset, then ride up and watch it set a second time.

  4. The Mariana Trench (depth) 11 km

    If Everest were dropped into it, the peak would still sit more than two kilometres below the surface.

  5. The Panama Canal 85 km

    Ships are lifted 26 metres above sea level by locks, then lowered again, crossing a continent without touching the ocean between.

  6. Norway (length) 1.8K km

    Stretched out, Norway is so long that its northern tip is closer to the North Pole than to its own southern coast.
