Cambodia covers 181,373 km² km² on the new Equal Earth world map — 0.1%% of all land on Earth, making it the 89th largest country in the world and the 25th largest in Asia. At 13° latitude Mercator only inflates Cambodia 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: Cambodia is roughly the same size as Tunisia (156,653 km² km²).
You could fit 4 of Denmark inside Cambodia.
