💡 Board Feet Formula & Tips

  • Formula: Board Feet = (Thickness” × Width” × Length’) ÷ 12
  • Example: 2×4×8 = (2 × 4 × 8) ÷ 12 = 5.33 BF
  • Nominal vs Actual: A “2×4″ is actually 1.5″ × 3.5”
  • Average weight: ~3 lbs per board foot (varies by species)
  • Hardwood pricing is typically per board foot
  • Softwood (construction lumber) often priced per piece
  • 1 board foot = 144 cubic inches = 1/12 cubic foot
