A typical cord of wood is 4 feet high by 8 feet long by 4 feet wide with a volume of 128 cubic feet. A variation of the cord is the face cord, generally measuring 4 feet high by 8 feet long with 16 inch wide pieces.
A full cord is rarely sold by firewood dealers because 4 feet wide pieces of wood are too big for many home heating units. As a result, the face cord is generally sold by firewood dealers, as smaller pieces of wood are more functional. Face cords of wood generally cost more per volume than full cords because the pieces require labor and cutting.
