Europe dwarfs Myanmar: about 10,180,000 km² km² against 662,746 km² km². At true size Europe is about 15.4× larger — the whole of Myanmar fits into Europe roughly 15 times.
The old Mercator map treated both about equally (1× vs 1.2× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Myanmar fits 15× into Europe.
