Why the map you grew up with disagrees

On a Mercator map, area grows with distance from the equator. Indonesia sits at about 2°S and is stretched to 1.0× its true area; Mongolia at 47° N is stretched to 2.15×. That difference is why Mongolia looks so much bigger than it is next to Indonesia. The figure above uses the Equal Earth projection, where every square kilometre is drawn the same size.
