size it up.

A little perspective

Trust your eye.

Use the country on the left as your reference. Resize the country on the right until its east–west width or north–south height looks correct, then lock in your estimate.

  1. Compare

    North is up. Compare width or height, not land area.

  2. Find the right size

    Drag the blue handle, scroll while hovering it, tap − / +, or use the arrow keys. Match the dimension in the question.

  3. Lock it in

    Reveal the real size and earn up to 100 points. Five rounds add up to a maximum of 500.

The first answer in each round counts. A new challenge arrives every day at 00:00 UTC. Object sizes use the specific examples shown in the answer.
