Why raw area is misleading on a world map
Standard web maps use the Mercator projection, which stretches shapes further from the equator. That's why London and Tokyo can look similar on a map even when one is many times larger. To really feel the difference, you have to overlay one city's outline directly on top of the other at true scale.
