Africa dwarfs Kazakhstan: about 30,370,000 km² km² against 2,712,747 km² km². At true size Africa is about 11.2× larger — the whole of Kazakhstan fits into Africa roughly 11 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.
Kazakhstan fits 11× into Africa.
