A cord of wood measures 4 feet high, 4 feet wide and 8 feet long. Terms such as face cord, stove cord and furnace cord represent wood that is stacked 4 feet high and 8 feet long and less than 4 feet wide, according to the Wood Heat Organization, Inc.
A full cord of firewood generally contains about 85 cubic feet of solid wood due to air spaces in the stack. Sellers sometimes refer to face cord or stove cord to indicate shorter pieces of wood. Firewood typically measures 16 inches long, so the dimensions of a stack that is 4 feet high, 16 inches wide and 8 feet long represents a stove cord, or one-third of a cord.
