Guatemala covers 108,520 km² km² on the new Equal Earth world map — 0.1%% of all land on Earth, making it the 106th largest country in the world and the 8th largest in North America. At 16° latitude Mercator only inflates Guatemala by about 8%%, so the old and new maps largely agree on it — unlike the far north, where Mercator's stretch is dramatic.
For scale: Guatemala is roughly the same size as Cuba (109,285 km² km²).
