Wired:

A new web app called The True Size Of is an interactive map that its creators, James Talmage and Damon Maneice, hope will give people a better understanding of a country’s true size. Dragging one country across the map causes it to change size and shape in real time, allowing you to place it beside countries at other latitudes and compare their relative sizes. For example, as you overlay the United States on top of Greenland, the former stretches and bloats. Meanwhile, dragging Greenland down toward Saudi Arabia, causes the northerly country to shrink dramatically in size.

It’s a simple tool, but it’s wildly effective at granting a new perspective on the size and shape of the world’s various land masses.

There’s no doubt the vast majority of us learned what we know of world geography from a Mercator map but this online tool shows just how inaccurate our impressions of the size of various countries really is.
