Calculate lumber volume in board feet, cubic feet, cubic inches, and cubic meters. Use this lumber volume calculator to estimate total boards, waste allowance, lumber weight, cost per board foot, total material cost, and project lumber needs.
Board feet from dimensions:
The calculator converts thickness, width, and length into board feet, then multiplies by the number of boards.
Cubic volume:
The calculator converts dimensions into cubic feet, cubic inches, cubic yards, and cubic meters.
Known board feet:
Enter a known board foot amount to estimate cubic feet, weight, waste, and cost.
Lumber cost:
The calculator can estimate total cost using price per board foot, price per board, waste allowance, and delivery fees.
A lumber volume calculator helps estimate how much wood is needed before buying, cutting, hauling, or pricing lumber.
It can be useful for woodworking, sawmills, lumber yards, cabins, decks, fencing, furniture, shelving, framing, rough lumber, hardwood boards, and project material planning.
Your result shows total board feet, board feet with waste, cubic feet, cubic inches, cubic meters, estimated lumber weight, price estimate, delivery fee, total material cost, and cost per board. These are planning estimates based on the dimensions, quantity, wood type, waste allowance, and prices you enter.
Multiply thickness in inches by width in inches by length in feet, then divide by 12. Multiply by the number of boards for the total.
One board foot is a piece of wood 12 inches wide, 12 inches long, and 1 inch thick, equal to 144 cubic inches.
One cubic foot equals 12 board feet because a cubic foot contains 1,728 cubic inches and one board foot contains 144 cubic inches.
Yes. A waste allowance helps cover saw kerf, trimming, defects, knots, splits, cuts, layout changes, and mistakes.
