Botswana covers 580,622 km² km² on the new Equal Earth world map — 0.4%% of all land on Earth, making it the 48th largest country in the world and the 23rd largest in Africa. At 22° latitude Mercator only inflates Botswana by about 17%%, so the old and new maps largely agree on it — unlike the far north, where Mercator's stretch is dramatic.
For scale: Botswana is roughly the same size as Morocco (582,378 km² km²).
