Why the map you grew up with disagrees

On a Mercator map, area grows with distance from the equator. Iceland sits at about 65°N and is stretched to 5.6× its true area; Japan at 37° N is stretched to 1.59×. That difference is why Iceland looks so much bigger than it is next to Japan. The figure above uses the Equal Earth projection, where every square kilometre is drawn the same size.
