Why maps make London and New Jersey look wrong

Almost every web map — Google Maps, Apple Maps, OpenStreetMap — uses the Mercator projection. Mercator preserves shape locally, but it stretches land the further you get from the equator. Greenland ends up looking bigger than Africa. Alaska rivals the contiguous US. That's why London and New Jersey can look similar on a world map even when one is many times larger. The only fair way to compare is to lift one outline off the map and drop it on top of the other at true scale.
