There is no way to accurately project a spherical surface onto a two-dimensional map. Something has to be inaccurate, size, shape, distance, and or direction. The advantage of the Mercator projection is that it preserves direction, which is useful for navigation.

The Short Answer

There is no way to accurately project a spherical surface onto a two-dimensional map. Something has to be inaccurate, size, shape, distance, and or direction. The advantage of the Mercator projection is that it preserves direction, which is useful for navigation. It is also rectangular, so it better utilizes the space on a rectangular map. There are [several other](_URL_0_) map projections, all with their strengths and weaknesses.
