I am woefully bad at geography. Without any innate sense of how cities compare, I found this series of maps, produced by the self-storage company SpareFoot using MAPfrappe, endlessly fascinating and surprising. But even if you already knew that New York City boasts a full 10 times the population of San Francisco (10 times!), these comparisons are a great visual.

Tokyo is so sprawling that it manages to be less dense (at least, on average) than New York City, despite a population more than 13 million. If you think New York is too crowded, Paris is definitely not for you. And when it comes to wide open spaces Sitka, Alaska can't be beat.
