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.

Answers from this past challenge. Today’s challenge remains a surprise.

Simplified outlines from Natural Earth face north. Answers give approximate east–west or north–south spans in kilometres, not land areas or the distance between the farthest points. Some remote islands are omitted; each answer explains the included territory.

  1. Round 1

    How wide is France compared with Zambia?

    Zambia, used for the east–west width comparison
    ReferenceZambia≈ 1,270 km east–west
    France, used for the east–west width comparison
    Compared objectFrance≈ 1,100 km east–west

    Illustrations shown individually, not to a shared scale.

    Actual size ratio

    ≈ 0.8704×

    France ÷ Zambia, comparing east–west width.

    This simplified Natural Earth outline of France shows mainland France, Corsica and nearby European islands, excluding overseas territories. Its approximate east–west span is 1,100 km in a local equirectangular projection corrected at the outline's middle latitude. This is a projected extent, not land area.
