Central African Republic dwarfs Europe: about 620,987 km² km² against 10,180,000 km² km². At true size Central African Republic is about 16.4× larger — the whole of Europe fits into Central African Republic roughly 16 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 16× into Europe.
