1x6x10 — Weight and Board Feet

A 1x6 cut to 10 ft: 5 board feet of nominal section, and 0.2865 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 5 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 × 10 × 12) ÷ 144 = 5 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 0.2865 cubic feet.

Frequently asked questionsabout a 1x6x10

How much does a 1x6x10 weigh?

In Spruce (Sitka), about 7.69 lb (3.49 kg). Across the species in this database it ranges from 2.86 lb in Balsa to 17.88 lb in Ipe.

How many board feet is a 1x6x10?

5 board feet, calculated from the nominal section: (1 × 6 × 120) ÷ 144.

What are the actual dimensions of a 1x6x10?

0.75 × 5.5 inches in section, 10 ft long — 19.05 × 139.7 millimetres by 10 feet. The nominal 1 × 6 inch call size is the rough green section.
