Mali dwarfs North America: about 1,258,185 km² km² against 24,710,000 km² km². At true size Mali is about 19.6× larger — the whole of North America fits into Mali roughly 19 times.
The old Mercator map treated both about equally (1.1× vs 1× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Mali fits 19× into North America.
