Asia dwarfs India: about 44,580,000 km² km² against 3,155,807 km² km². At true size Asia is about 14.1× larger — the whole of India fits into Asia roughly 14 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 14× into Asia.
