Your order works out to about 80 board feet.

  • One board foot is 144 cubic inches, a 1 in x 12 in x 1 ft board, so 10 pieces add up to 80 net board feet (80 lineal feet).
  • Hardwood is usually priced by the board foot or per MBF, while softwood framing is often sold per piece or per lineal foot instead.

Next stepSet a waste allowance of about 10-15% to cover knots, cracks and trimming before you buy.
