Cameroon covers 465,902 km² km² on the new Equal Earth world map — 0.4%% of all land on Earth, making it the 54th largest country in the world and the 25th largest in Africa. At 6° latitude Mercator only inflates Cameroon by about 1%%, so the old and new maps largely agree on it — unlike the far north, where Mercator's stretch is dramatic.
For scale: Cameroon is roughly the same size as Somalia (473,622 km² km²).
