Why the map you grew up with disagrees

On a Mercator map, area grows with distance from the equator. Cambodia sits at about 13°N and is stretched to 1.05× its true area; Japan at 37° N is stretched to 1.59×. That difference is why Japan looks so much bigger than it is next to Cambodia. The figure above uses the Equal Earth projection, where every square kilometre is drawn the same size.
