By size · Order from shortest to longest.

1. The width of a human hair 0.1 mm

   Hair width is so consistent it was once a unit of precision; forensic labs still match hairs to within fractions of this.

2. A French baguette 63 cm

   French law defines the traditional baguette so strictly it can contain only flour, water, salt and yeast.

3. A red kangaroo (standing) 1.5 m

   Kangaroos cannot walk backwards, a trait so iconic it earned them a spot on Australia's coat of arms.

4. A classic Volkswagen Beetle 4.1 m

   The Beetle stayed in production for over 65 years, making it one of the longest-running car designs ever.

5. A yellow school bus 13.7 m

   That specific shade, 'school bus yellow', was chosen in 1939 because it stays visible in dim dawn light.

6. The Strait of Gibraltar (narrowest width) 14.4 km

   It is so narrow that on a clear day you can see Africa from Europe across the water.
