Egypt dwarfs Europe: about 1,003,707 km² km² against 10,180,000 km² km². At true size Egypt is about 10.1× larger — the whole of Europe fits into Egypt roughly 10 times.
The old Mercator map treated both about equally (1.3× vs 1× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Egypt fits 10× into Europe.
