After looking at a world map which had Mercator cylindrical projection (the type of maps where the lines of longitude are parallel with each other) in one of my early years in school, I thought that Greenland was more than twice the size as Australia because Greenland is at a high latitude and has been severely stretched out (Australia is actually about three and a half times the size of Greenland). It took me a long time to realise that on those kinds of maps, the distance between the lines of longitude decreases with latitude.
