Argentina dwarfs North America: about 2,782,703 km² km² against 24,710,000 km² km². At true size Argentina is about 8.9× larger — the whole of North America fits into Argentina roughly 8 times.
The old Mercator map treated both about equally (1.5× vs 1× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Argentina fits 8× into North America.
