{{see also|List of map projections}}
All world maps are based on one of several map projections, or methods of representing a [[globe]] on a plane. All projections distort geographic features, distances, and directions in some way. The various map projections that have been developed provide different ways of balancing accuracy and the unavoidable distortion inherent in making world maps.

Perhaps the best-known projection is the [[Mercator Projection]], originally designed as a [[nautical chart]].
