TrueSize™: Compare Real Country Sizes

Explore the true size of countries and regions on a map

Drag countries, states, provinces, and continents across the map to reveal how the Mercator projection distorts area. Compare more than 760,000 regions, historical borders for any year, mountains, lakes, and language areas — and see them at true size on the Moon and other planets.

2. Drag to compare — Move countries across the map to understand how latitude changes their apparent size.
