Board Footage Calculator
Calculate lumber board feet for your construction and woodworking projects
Board Feet Measurement
Board feet (BF) is the standard unit of measurement for lumber volume in North America. This measurement system helps contractors, woodworkers, and lumber dealers calculate the amount of wood needed for projects and determine pricing accurately.
One board foot represents a piece of lumber that measures 12 inches long, 12 inches wide, and 1 inch thick, totaling 144 cubic inches. This standardized measurement allows for consistent pricing and planning across the lumber industry, regardless of the actual dimensions of individual boards.
The board foot calculation is essential for construction projects, furniture making, flooring installation, and any woodworking endeavor where precise material estimation is crucial for budgeting and avoiding waste.
How to Use the Board Footage Calculator
Step 1: Enter Length Measurement
Input the length of your lumber piece in the first field. Select whether you’re measuring in feet or inches using the dropdown menu. Most lumber is sold in standard lengths, but custom cuts are common in woodworking projects.
Step 2: Input Width Dimensions
Enter the width of your board in the second field. Width is typically measured in inches for lumber, but you can select feet if working with larger dimensions. This measurement represents the face width of the board.
Step 3: Specify Thickness
Add the thickness measurement of your lumber. Thickness is usually expressed in inches and represents the actual thickness of the board after planing. Common thicknesses include 1 inch, 1.5 inches, and 2 inches.
Step 4: Set Quantity
Specify how many pieces of lumber you need with identical dimensions. The calculator will compute both the board feet per piece and the total board feet for all pieces, helping you estimate material costs and requirements.
Step 5: Calculate and Review Results
