Board foot. A board foot (BF) is the unit of measurement for hardwood lumber. A board foot is 1 foot long x 1 foot wide x 1 inch thick. (1 foot = 0.305 metres, 1 inch = 25.4mm) The formula for determining board feet in a board is: (Width in inches x length in feet x thickness in inches) divided by 12. The percentages of clear wood required for each grade are based on this 12' unit of measure.
Treads are the horizontal boards that you step on. Treads may be made of a single 2x12 or 2x10, but are often made of two decking boards or 2x6s. A stringer is a wide board, usually a 2x12, that runs at an angle from the landing pad to the deck framing and supports the treads.
