Iran covers 1,622,847 km² km² on the new Equal Earth world map — 1.2%% of all land on Earth, making it the 18th largest country in the world and the 6th largest in Asia. At 33° latitude the old Mercator map inflates area by about 1.4×, so it drew Iran closer to 2,288,214 km² km² — a difference of roughly 41%%.
For scale: Iran is roughly the same size as Libya (1,626,369 km² km²).
