South America dwarfs Turkey: about 17,840,000 km² km² against 779,797 km² km². At true size South America is about 22.9× larger — the whole of Turkey fits into South America roughly 22 times.
The old Mercator map treated both about equally (1× vs 1.7× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Turkey fits 22× into South America.
