The True Size Of

Drag countries on a map to compare their true size — reveals how distorted Mercator projection maps really are.
The True Size Of lets you drag countries around a map to compare their real sizes. Standard web maps use the Mercator projection, which stretches areas near the poles, so Greenland looks as big as Africa. Drag one country over another and the tool redraws it at the correct size for its new position.
You can pick countries, states and provinces, rotate them and stack several together. It is a quick way to see map distortion, and teachers use it for geography lessons. It is free and runs in the browser with no signup.
Why it is useful
Mercator projection makes Greenland appear larger than Africa when Africa is actually 14 times bigger. This tool makes that distortion viscerally clear by letting you drag country outlines across the globe to compare true sizes.
