Lumber Weight

How much does a E. White Pine 2×4 weigh?

An E. White Pine 2×4, 8 ft weighs 7.3 lb (3.3 kg) at 12% moisture content, kiln-dried.

25.1 lb/ft³ · 5.33 bd ft ·

The answer above uses the actual dressed size — a nominal 2×4 of Eastern White Pine measures 1-1/2″ × 3-1/2″ once surfaced dry (PS 20-25) — and the species' basic specific gravity of 0.34 from the USDA Wood Handbook. At 12% moisture content that works out to 25.1 lb/ft³, or 0.9 lb per linear foot.

Dashed: nominal 2×4. Solid: actual dressed size, surfaced dry (PS 20-25).

Green weights show the heartwood-to-sapwood moisture range (62%–148% MC for this species) — a fresh-cut board lands somewhere inside it. Board feet use nominal dimensions, as lumber is priced; weight uses actual dimensions. Expect ±10-15% piece-to-piece variation in any stack. How these are computed.
