New Caledonia covers 18,648 km² km² on the new Equal Earth world map — 0.0%% of all land on Earth, making it the 155th largest country in the world and the 5th largest in Oceania. At 21° latitude Mercator only inflates New Caledonia by about 15%%, so the old and new maps largely agree on it — unlike the far north, where Mercator's stretch is dramatic.
