The dimensions for a full cord of wood are 4 feet high by 4 feet wide by 8 feet long. Its volume is 128 cubic feet.
Firewood is often sold in units other than a traditional cord, such as a fireplace or face cord. These indicate smaller amounts of wood. A fireplace cord is generally one-third the size of a full cord.
Depending upon the length of the logs, a face cord runs between one-fourth and one-half of a full cord. Fireplace logs are typically 16 inches long. However, other measurements are sometimes used, typically 12 or 24 inches. On average, three face cords equal one full cord.
