How Mercator draws it
The middle of Brazil is at about 11° S. Mercator stretches each place by the same amount across and up, more the further it is from the equator, so here every area comes out 1.04× its true size.
At the equator nothing is stretched. At 60° north or south, everything is drawn at four times its true area. The poles never fit on the map at all.
