Canada dwarfs Democratic Republic of the Congo: about 9,872,102 km² km² against 2,334,703 km² km². At true size Canada is about 4.2× larger — the whole of Democratic Republic of the Congo fits into Canada roughly 4 times.
Canada sits in North America, Democratic Republic of the Congo in Africa. On the old Mercator map the latitude gap distorted how large each felt beside the other; at true size the answer is simply 4.2×.
The old map muddied it further: Mercator inflates Canada about 4.1× and Democratic Republic of the Congo about 1×, so on a Mercator-style map this pair appears 17.3× apart instead of the true 4.2×.
Democratic Republic of the Congo fits 4× into Canada.
