Botswana dwarfs North America: about 580,622 km² km² against 24,710,000 km² km². At true size Botswana is about 42.6× larger — the whole of North America fits into Botswana roughly 42 times.
The old Mercator map treated both about equally (1.2× vs 1× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Botswana fits 42× into North America.
