Asia dwarfs Democratic Republic of the Congo: about 44,580,000 km² km² against 2,334,703 km² km². At true size Asia is about 19.1× larger — the whole of Democratic Republic of the Congo fits into Asia roughly 19 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 19× into Asia.
