Libya dwarfs North America: about 1,626,369 km² km² against 24,710,000 km² km². At true size Libya is about 15.2× larger — the whole of North America fits into Libya roughly 15 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.
Libya fits 15× into North America.
