Bolivia dwarfs North America: about 1,090,271 km² km² against 24,710,000 km² km². At true size Bolivia is about 22.7× larger — the whole of North America fits into Bolivia roughly 22 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.
Bolivia fits 22× into North America.
