Board Foot Calculator
Calculate board feet, entered-dimension lumber volume, an optional allowance and cost from thickness, width, length and board count.
Open calculatorConstruction calculators
Plan construction quantities from clear measurements. Calculate lumber board feet, floor area, square yards, cubic yards, liquid depth and rectangular material mass. Start with the quantity you know: dimensions for area, area plus depth for volume, or volume plus density for mass. Worked guides explain rough lumber billing, mixed-shape pours, uneven layers, flooring cartons and carpet roll layouts. Net measured quantities remain separate from chosen allowances and supplier order increments.
