Ukraine covers 570,135 km² km² on the new Equal Earth world map — 0.4%% of all land on Earth, making it the 49th largest country in the world and the 3rd largest in Europe. At 49° latitude the old Mercator map inflates area by about 2.3×, so it drew Ukraine closer to 1,334,116 km² km² — a difference of roughly 134%%.
For scale: Ukraine is roughly the same size as Botswana (580,622 km² km²).
