Afghanistan covers 642,058 km² km² on the new Equal Earth world map — 0.5%% of all land on Earth, making it the 41st largest country in the world and the 11th largest in Asia. At 34° latitude the old Mercator map inflates area by about 1.5×, so it drew Afghanistan closer to 930,984 km² km² — a difference of roughly 45%%.
For scale: Afghanistan is roughly the same size as France (635,064 km² km²).
