Europe dwarfs Mozambique: about 10,180,000 km² km² against 790,643 km² km². At true size Europe is about 12.9× larger — the whole of Mozambique fits into Europe roughly 12 times.
The old Mercator map treated both about equally (1× vs 1.1× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Mozambique fits 12× into Europe.
