Malaysia covers 327,621 km² km² on the new Equal Earth world map — 0.2%% of all land on Earth, making it the 68th largest country in the world and the 19th largest in Asia. At 4° latitude Mercator only inflates Malaysia by about 0%%, so the old and new maps largely agree on it — unlike the far north, where Mercator's stretch is dramatic.
For scale: Malaysia is roughly the same size as Vietnam (328,959 km² km²).
