20-mile hexes are the standard size for mapping expansive areas of the game world, called sheet maps. Hexes measure 20 miles from side to side, with an area of 259 square miles per hex.
Area references for national districts are measured in hexes rather than square miles, as it is easier for players to envision an area that covers seven 20-mile hexes than 1,813 square miles. Incidentally, seven 20-mile hexes would be an area slightly larger than the U.S. state of Rhode Island.
20-mile hexes can be subdivided into 6-mile hexes and 2-mile hexes as shown by the diagram below. This allows sheet maps to be zoomed in order to give more detail of areas when desired.
