South Korea covers 97,165 km² km² on the new Equal Earth world map — 0.1%% of all land on Earth, making it the 108th largest country in the world and the 30th largest in Asia. At 36° latitude the old Mercator map inflates area by about 1.5×, so it drew South Korea closer to 149,634 km² km² — a difference of roughly 54%%.
For scale: South Korea is roughly the same size as Iceland (101,161 km² km²).
