Burkina Faso covers 273,690 km² km² on the new Equal Earth world map — 0.2%% of all land on Earth, making it the 74th largest country in the world and the 29th largest in Africa. At 12° latitude Mercator only inflates Burkina Faso by about 5%%, so the old and new maps largely agree on it — unlike the far north, where Mercator's stretch is dramatic.
For scale: Burkina Faso is roughly the same size as New Zealand (266,828 km² km²).
