Why the map you grew up with disagrees
On a Mercator map, area grows with distance from the equator. United Kingdom sits at about 54° N and is stretched to 2.9× its true area; United States at 45° N is stretched to 1.98×. That difference is why United Kingdom looks so much bigger than it is next to United States. The figure above uses the Equal Earth projection, where every square kilometre is drawn the same size.
