The True Size Of is an interactive app that seeks to improve our skewed sense of global geography by correcting the world map.

The web app allows users to drag a country to another part of the map. The country's size and shape will change until it compares accurately to its new location.

For a little background on why "the world's most ubiquitous map" is so distorted, Liz Stinson at Wired explains:

The Mercator projection is an inherently flawed design. It exaggerates the size of countries closest to the poles while depicting size most faithfully at the equator. Though it was once a handy navigational tool for sailors, the map has instilled in the rest of us a gross misunderstanding of geography and relative country size.
