About Board Feet
Board feet is a unit of measurement for lumber volume, representing the volume of a board that is 1 foot long, 1 foot wide, and 1 inch thick.
Board Feet Formula:
Board Feet = (Length × Width × Thickness) ÷ 144
Where:
- Length = Length in inches
- Width = Width in inches
- Thickness = Thickness in inches
- 144 = Conversion factor (12 × 12)
Common Lumber Sizes:
- 2×4: 1.5" × 3.5"
- 2×6: 1.5" × 5.5"
- 2×8: 1.5" × 7.25"
- 2×10: 1.5" × 9.25"
- 2×12: 1.5" × 11.25"
Applications:
• Lumber pricing
• Material estimation
• Construction planning
• Woodworking projects
• Inventory management
Log Scaling:
• Doyle Rule: Most common
• Scribner Rule: West Coast
• International Rule: Precise
• Used for log volume estimation
