Europe dwarfs Turkey: about 10,180,000 km² km² against 779,797 km² km². At true size Europe is about 13.1× larger — the whole of Turkey fits into Europe roughly 13 times.
The old Mercator map treated both about equally (1× vs 1.7× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Turkey fits 13× into Europe.
