On a Mercator map, area grows with distance from the equator. Guinea-Bissau sits at about 12°N and is stretched to 1.05× its true area; Vietnam at 17° N is stretched to 1.09×. 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.
