By size · Order from shortest to longest.

1. A single E. coli bacterium 2 µm

   About 2 micrometres long, E. coli divides every 20 minutes, so one cell can become billions inside a single day.

2. A television remote control 14 cm

   Most remotes talk to the TV with invisible infrared light, the same band of energy you feel as warmth.

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. 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.

5. The Grand Canyon (length) 446 km

   The Colorado River carved it over millions of years, exposing rock layers nearly two billion years old at the bottom.

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.
