128 cubic feet. Stack your wood neatly by placing the wood in a row, with the pieces touching and parallel to each other, and with as few gaps as possible. Multiply the length times the width times the height of the stack. If this equals 128 cubic feet, then you have a cord of wood. Common measurements of a cord of wood are 8 feet by 4 feet by 4 feet or 16 feet by 2 feet by 4 feet.
