1x6x16 — Weight and Board Feet

A 1x6 cut to 16 ft: 8 board feet of nominal section, and 0.4583 cubic feet of actual material to carry. Weight depends on the species, so it is tabulated below.

Board feet is a nominal-section convention; volume and weight use the actual section. The two are not interchangeable and are not meant to agree.

Weights are derived, not quoted: density at about 12% moisture content × actual volume. Treat them as a floor — green stock stays heavier until it dries. The spread across species is roughly six to one, so a freight or support estimate that assumes one figure for “a 1x6” can be wrong by a large margin.

Board feet explainedhow 8 bd ft is arrived at

A board foot is 144 cubic inches of nominal section — a board an inch thick, a foot wide and a foot long. Lumber is bought and sold on that basis, so the calculation uses the nominal thickness and width rather than the dressed ones:

(1 × 6 × 16 × 12) ÷ 144 = 8 board feet

The rated price therefore covers more wood than is delivered, which is the long-standing convention rather than an error. The actual volume of material in the same piece is 0.4583 cubic feet.
