The one common feature of WRG basing is that in any given scale all of the multi figure bases are the same width. It's the number of figures placed on each base (and the base's depth) that changes. This number of figures per base, 2, 3 or 4, determines how packed together the men are and is known as the unit's formation density (explained later).

The base width is more important than the depth, since it determines how many figures you can squeeze into any given combat. The depth is dependant upon the troop type and formation, and can be adjusted to allow for variations in figure bulkiness.
