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 Empire State Building 443 m

   It was built in just 410 days during the Great Depression, rising about a floor a day at peak speed.

4. 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.

5. A marathon course 42.2 km

   The odd distance was fixed in 1908 so the London race could start at Windsor Castle and finish before the royal box.

6. The River Thames (length) 346 km

   It was once so polluted that 1858's 'Great Stink' forced Parliament to finally build London's sewers.
