Belarus covers 206,698 km² km² on the new Equal Earth world map — 0.2%% of all land on Earth, making it the 85th largest country in the world and the 13th largest in Europe. At 54° latitude the old Mercator map inflates area by about 2.8×, so it drew Belarus closer to 584,955 km² km² — a difference of roughly 183%%.
For scale: Belarus is roughly the same size as United Kingdom (239,616 km² km²).
