Colombia dwarfs Europe: about 1,139,434 km² km² against 10,180,000 km² km². At true size Colombia is about 8.9× larger — the whole of Europe fits into Colombia roughly 8 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.
Colombia fits 8× into Europe.
