MapSize vs TrueSize

Traditional maps use the Mercator projection due to the earth's spherical shape, which distorts the size of countries near the poles. Because of this, you may be surprised to see how big some countries really are in comparison to others! With this app you can compare any two territories, move them around, and learn interesting statistics about their relative sizes. This is an excellent educational tool for students and teachers interested in geography.
