A cord of wood is approximately 8 feet long, 4 feet high and 4 feet wide. A cord of wood, or full or bush cord, is 128 cubic feet.
In some areas, firewood sells by the face cord or rick, which measures 8 feet long, 4 feet high and 16 inches wide, which is one-third of a cord. When used to describe a measure of wood, the term "cord" dates back to the 17th century, when people literally used a cord to measure stacks of wood. The creation of a standard measure made it easier to sell wood and buy wood.
