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.

Weight Estimation

Board Foot Weight Calculator

Convert board feet to weight based on wood species and moisture content. Essential for shipping, structural calculations, and material handling.

Moisture Content (%) (12% = kiln-dried)

Note: Weights are approximate. Actual weight varies by specific gravity, moisture content, and wood condition. Green lumber (>19% MC) weighs significantly more.

Moisture Content

Green: 50-100% (freshly cut)
Air-dried: 15-20%
Kiln-dried: 6-12%

Wood Density Ranges

Softwoods: 20-35 lbs/cu ft
Hardwoods: 35-55 lbs/cu ft
Exotic: 40-70 lbs/cu ft

Frequently Asked Questions

How much does a board foot of oak weigh?

Red oak at 12% moisture content weighs approximately 3.75 lbs per board foot. White oak is slightly heavier at about 3.9 lbs/BF.

Does moisture content affect weight significantly?

Yes! Green lumber can weigh 2-3 times more than kiln-dried. Water adds significant weight. A board at 50% MC weighs much more than the same board at 12% MC.

How do I calculate shipping weight?

Calculate total weight, add 10-15% for packaging/pallets. Standard pallet holds ~2,000 lbs. Full truck load is typically 40,000-45,000 lbs.
