Why the map you grew up with disagrees
On a Mercator map, area grows with distance from the equator. Monaco sits at about 44° N and is stretched to 1.92× its true area; San Marino at 44° N is stretched to 1.93×. Here the two are distorted about the same amount, so Mercator gets this pair roughly right. The figure above uses the Equal Earth projection, where every square kilometre is drawn the same size.
