Both maps below show Guyana highlighted. At 5° Mercator inflates Guyana by only about 1%, so the two maps largely agree on it. Watch what the old map does to Dominican Republic beside it. That contrast is why the new world map matters.
At 5°, Guyana 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.
