Nicaragua covers 129,225 km² km² on the new Equal Earth world map — 0.1%% of all land on Earth, making it the 98th largest country in the world and the 5th largest in North America. At 13° latitude Mercator only inflates Nicaragua by about 5%%, so the old and new maps largely agree on it — unlike the far north, where Mercator's stretch is dramatic.
For scale: Nicaragua is roughly the same size as Greece (130,177 km² km²).
You could fit 3 of Denmark inside Nicaragua.
