Drag a shape to move it — watch it grow toward the poles; that's the Mercator distortion. Tap ✕ on a shape to remove it. On a keyboard: arrow keys nudge, Delete removes.

The world map you grew up with — the Web Mercator projection — stretches land near the poles. Greenland looks as big as Africa. It is 14 times smaller.
TrueScale keeps each shape's real, on-the-ground size as you drag it. Move a country toward a pole and it balloons, exactly as Mercator distorts it. Move it to the equator to see its honest size.
