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 standard paperclip 3.2 cm

   The familiar looped design, called the Gem clip, was never patented and has barely changed in over a century.

3. A golf ball 4.3 cm

   A golf ball has 300 to 500 dimples; they cut drag and roughly double how far a struck ball will fly.

4. A sperm whale 16 m

   Its head holds the largest brain of any animal that has ever lived, weighing about as much as a small person.

5. The Taj Mahal 73 m

   Its white marble appears to change colour through the day, glowing pink at dawn and golden under moonlight.

6. New Zealand's South Island (length) 840 km

   It is home to fewer than two million people but more than ten times as many sheep.
