Why the map you grew up with disagrees

On a Mercator map, area grows with distance from the equator. Japan sits at about 37°N and is stretched to 1.59× its true area; Thailand at 15° N is stretched to 1.07×. That difference is why Japan looks so much bigger than it is next to Thailand. The figure above uses the Equal Earth projection, where every square kilometre is drawn the same size.
