Closer than most people guess: Democratic Republic of the Congo (2,344,858 km²) is only about 8% larger than Greenland (2,166,086 km²).
Democratic Republic of the Congo sits in Africa, Greenland in North America. On the old Mercator map the latitude gap distorted how large each felt beside the other; at true size the answer is simply 1.1×.
The old map muddied it further: Mercator inflates Democratic Republic of the Congo about 1.00× and Greenland about 11.8×, so on a Mercator-style map this pair appears 10.9× apart instead of the true 1.1×.
Greenland fits 1× into Democratic Republic of the Congo.
