Brazil covers 8,499,400 km² km² on the new Equal Earth world map — 6.3%% of all land on Earth, making it the 5th largest country in the world and the 1st largest in South America. At 11° latitude Mercator only inflates Brazil by about 4%%, so the old and new maps largely agree on it — unlike the far north, where Mercator's stretch is dramatic.
For scale: Brazil is roughly the same size as China (9,371,225 km² km²).
You could fit 3 of Argentina inside Brazil.
