Paraguay covers 400,900 km² km² on the new Equal Earth world map — 0.3%% of all land on Earth, making it the 60th largest country in the world and the 8th largest in South America. At 23° latitude Mercator only inflates Paraguay by about 18%%, so the old and new maps largely agree on it — unlike the far north, where Mercator's stretch is dramatic.
For scale: Paraguay is roughly the same size as Zimbabwe (390,202 km² km²).
