GREENLAND & AFRICA

Why does Greenland look so large?

On a Mercator world map, Greenland can look about as large as Africa.

But in reality, Africa is about 14 times the area of Greenland.

This is because Greenland lies at a high latitude, and Mercator makes high-latitude regions look larger.

They look about the same size on Mercator

The comparison below uses the same scale in the Equal Earth projection. This makes the actual area difference between Africa and Greenland visible. The statement that Africa is about 14 times larger is based on the official Equal Earth explanation. Source ↗

MERCATOR

Mercator

Mercator preserves local angles and can show constant-bearing routes as straight lines, but area grows strongly toward the poles.

EQUAL EARTH

Equal Earth

Equal Earth is an equal-area projection: relative areas are preserved, while shape, distance and direction can still be distorted.

WHY?

Why do world maps distort?

Earth is round. A world map is flat. Flattening a globe always changes something: area, shape, distance or direction.
