South America dwarfs Venezuela: about 17,840,000 km² km² against 914,310 km² km². At true size South America is about 19.5× larger — the whole of Venezuela fits into South America roughly 19 times.
The old Mercator map treated both about equally (1× vs 1× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Venezuela fits 19× into South America.
