Algeria covers 2,322,788 km² km² on the new Equal Earth world map — 1.7%% of all land on Earth, making it the 11th largest country in the world and the 2nd largest in Africa. At 28° latitude Mercator only inflates Algeria by about 28%%, so the old and new maps largely agree on it — unlike the far north, where Mercator's stretch is dramatic.
For scale: Algeria is roughly the same size as Greenland (2,154,754 km² km²).
You could fit 3 of Zambia inside Algeria.
