Kazakhstan dwarfs South America: about 2,712,747 km² km² against 17,840,000 km² km². At true size Kazakhstan is about 6.6× larger — the whole of South America fits into Kazakhstan roughly 6 times.
The old Mercator map treated both about equally (2.3× vs 1× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Kazakhstan fits 6× into South America.
