Both maps below show Northern Mariana Islands highlighted. At 16° Mercator inflates Northern Mariana Islands by only about 8%, so the two maps largely agree on it. Watch what the old map does to Japan beside it. That contrast is why the new world map matters.
At 16°, Northern Mariana Islands sits in the band the old map drew almost honestly. It is one of the regions Mercator quietly under-represented, and that is exactly what the new Equal Earth map restores.
