Lumber Calculators.
Lumber calculators help estimate boards, sheets, joists, studs, lineal footage, board feet, and wood weight from project dimensions.
Why use these tools?
Wood orders vary by nominal dimensions, spacing, sheet coverage, board length, species, moisture, and waste. Calculators help convert a layout into a buying list.
How to choose
Use framing or joist calculators for structural layouts, plywood for sheet goods, board-foot tools for hardwood or rough lumber, and log weight for handling or transport estimates.

Common questions
What is a board foot?
A board foot is a wood volume equal to a board 12 inches long, 12 inches wide, and 1 inch thick. It is common for hardwood and rough lumber estimates.
Do lumber calculators include waste?
Several lumber tools include waste or stock-piece assumptions. Add more waste for angled cuts, defects, complicated layouts, or when matching boards.
