  1. A credit card 8.6 cm

    Every card's dimensions follow a global standard so it fits machines from Tokyo to Toronto.

  2. 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.

  3. Angel Falls, Venezuela 979 m

    The world's tallest waterfall is so high the water often atomises into mist before it ever reaches the ground.

  4. Mont Blanc, the Alps 4.8 km

    Its summit is buried under permanent ice so thick that the official height changes slightly with the snow each year.

  5. Mount Everest 8.8 km

    Its summit is made of marine limestone, lifted from an ancient seabed, so the top of the world was once underwater.

  6. 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.
