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.

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 Vietnam compared with Turkey?

    Turkey, used for the east–west width comparison
    ReferenceTurkey≈ 1,660 km east–west
