Europe dwarfs India: about 10,180,000 km² km² against 3,155,807 km² km². At true size Europe is about 3.2× larger — the whole of India fits into Europe roughly 3 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.
India fits 3× into Europe.
