South Africa covers 1,221,609 km² km² on the new Equal Earth world map — 0.9%% of all land on Earth, making it the 24th largest country in the world and the 8th largest in Africa. At 29° latitude Mercator only inflates South Africa by about 31%%, so the old and new maps largely agree on it — unlike the far north, where Mercator's stretch is dramatic.
For scale: South Africa is roughly the same size as Angola (1,249,380 km² km²).
