Africa dwarfs Democratic Republic of the Congo: about 30,370,000 km² km² against 2,334,703 km² km². At true size Africa is about 13× larger — the whole of Democratic Republic of the Congo fits into Africa roughly 13 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.
Democratic Republic of the Congo fits 13× into Africa.
