Asia dwarfs Pakistan: about 44,580,000 km² km² against 873,772 km² km². At true size Asia is about 51× larger — the whole of Pakistan fits into Asia roughly 51 times.
The old Mercator map treated both about equally (1× vs 1.3× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Pakistan fits 51× into Asia.
