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.
Early standards called for green rough lumber to be of full nominal dimension when dry. However, the dimensions have diminished over time. In 1910, a typical finished 1-inch (25 mm) board was 13â16 in (21 mm). In 1928, that was reduced by 4%, and yet again by 4% in 1956.
