Somalia covers 473,622 km² km² on the new Equal Earth world map — 0.4%% of all land on Earth, making it the 52nd largest country in the world and the 24th largest in Africa. At 5° latitude Mercator only inflates Somalia 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: Somalia is roughly the same size as Cameroon (465,902 km² km²).
You could fit 3 of Tunisia inside Somalia.
