CityVersusCity — Discover the True Size of Cities
CityVersusCity is an interactive tool that lets you visually compare the true geographic size of cities, states, and countries around the world. Ever wondered how New York compares to Tokyo? Or how Texas stacks up against Germany? Now you can see it with your own eyes.
We overlay real geographic boundaries to scale, so you can finally understand just how big (or small) different places really are.
