On a Mercator map, area grows with distance from the equator. New Caledonia sits at about 21°S and is stretched to 1.15× its true area; Papua New Guinea at 6° S is stretched to 1.01×. 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.
