How many board feet is a 2x4x8?

Using actual dressed size 1.5″ × 3.5″ × 8′ → (1.5 × 3.5 × 8) ÷ 12 = 3.5 BF. Using nominal 2″ × 4″ × 8′ → (2 × 4 × 8) ÷ 12 = 5.333 BF.

How to calculate BDFt?

A meter is slightly longer — roughly 9.36% longer than a yard. (1 m ≈ 1.0936 yd)

How much is 1000 board feet of lumber?

1,000 BF is an MBF. Cost = price per BF × 1000 (varies by species, grade, and market)

How to calculate BDFt in a log?

Logs are typically scaled by rules (Doyle, Scribner, International 1/4) using small-end diameter inside bark and length. Choose the rule common in your region or buyer’s request for consistent results.

Wood Species (for weight estimate)

Hardwoods

Oak, maple, walnut, cherry, and ash. Typically denser and more expensive. Popular for furniture, flooring, and cabinetry.

Softwoods

Pine, cedar, fir, and spruce. Lighter weight and easier to work. Used for framing, decking, and general construction.

Exotic Woods

Teak, mahogany, ebony, and rosewood. Premium species with unique properties. Priced by the board foot at specialty dealers.

Frequently Asked Questions

How do I calculate board feet for rough lumber?

Use actual measured dimensions. Rough lumber is typically closer to nominal size (e.g., a rough 1×6 is actually about 1″ × 6″).

Does wood species affect board feet?

No, board feet is a volume measure independent of species. However, species affects weight, workability, and price per board foot.

How much waste should I add?

Add 10-20% for cuts, defects, and mistakes. Complex projects or knotty wood may need 25% or more waste factor.
