Board-foot and deck-board tools for pricing lumber, checking takeoffs, and turning rough dimensions into an order that makes sense.
Calculate board feet from length, width, and thickness. Essential for lumber ordering, woodworking projects, and estimating material costs.
Determine the number of boards needed for deck construction, including spacing and coverage. Perfect for pressure-treated, composite, and hardwood decks.
This section is for the two common jobs that usually cause order mistakes: converting stock into board feet and figuring out how many deck boards a layout actually needs once spacing is included.
The board-foot calculator is useful when the yard is quoting hardwood, rough stock, or mixed dimensions. The deck-board calculator is useful when a simple square-foot estimate is not enough because spacing, overhang, and board width all change the final count.
Nominal versus actual dimensions, waste from defects or cuts, and the material itself. A clean rectangular layout is one thing. A deck with picture framing, diagonal boards, stairs, or odd transitions is another.
Use the calculator to get the base number, then add waste based on the job. Straight runs may need only a modest cushion. Higher-end finish work, selective hardwood stock, and layouts with lots of cuts usually need more.
