Egypt dwarfs South America: about 1,003,707 km² km² against 17,840,000 km² km². At true size Egypt is about 17.8× larger — the whole of South America fits into Egypt roughly 17 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.
Egypt fits 17× into South America.
