China covers 9,371,225 km² km² on the new Equal Earth world map — 7.0%% of all land on Earth, making it the 4th largest country in the world and the 1st largest in Asia. At 37° latitude the old Mercator map inflates area by about 1.6×, so it drew China closer to 14,619,111 km² km² — a difference of roughly 56%%.
For scale: China is roughly the same size as United States (9,439,424 km² km²).
