Board Foot Calculator
Calculate board feet for your woodworking projects with our comprehensive calculator. Determine lumber volume needs based on dimensions, wood type, and waste factor for accurate material planning.
Step 1: Board Dimensions
Understanding Board Feet
One board foot equals 144 cubic inches of wood (1″ thick × 12″ wide × 12″ long). The formula is: (Thickness × Width × Length) ÷ 12 × Quantity = Total Board Feet.
Step 2: Calculation Parameters
About Waste Factor
The waste factor accounts for cutting losses, defects, and material that can’t be used. For most projects, 10-15% waste is typical. Higher quality wood or complex projects may require 20% or more.

Board Foot Calculation Breakdown
Board Foot Formula
Board Feet = (Thickness (in) × Width (in) × Length (ft)) ÷ 12 × Quantity
To calculate board feet: Multiply thickness (inches) by width (inches) by length (feet), divide by 12, then multiply by the number of boards. Add waste factor by increasing total by the waste percentage.
