Africa dwarfs Ukraine: about 30,370,000 km² km² against 570,135 km² km². At true size Africa is about 53.3× larger — the whole of Ukraine fits into Africa roughly 53 times.
The old Mercator map treated both about equally (1× vs 2.3× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Ukraine fits 53× into Africa.
