Why the map you grew up with disagrees

On a Mercator map, area grows with distance from the equator. Azerbaijan sits at about 40°N and is stretched to 1.72× its true area; Bulgaria at 43° N is stretched to 1.86×. 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.
