Morocco dwarfs South America: about 582,378 km² km² against 17,840,000 km² km². At true size Morocco is about 30.6× larger — the whole of South America fits into Morocco roughly 30 times.
The old Mercator map treated both about equally (1.3× vs 1× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Morocco fits 30× into South America.
