Central African Republic dwarfs North America: about 620,987 km² km² against 24,710,000 km² km². At true size Central African Republic is about 39.8× larger — the whole of North America fits into Central African Republic roughly 39 times.
The old Mercator map treated both about equally (1× vs 1× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Central African Republic fits 39× into North America.
