Lumber math is where a woodworking budget is won or lost. Order short and the build stalls. Order long and money sits in the rack. These calculators give you the number before you buy or cut.

Board feet is the unit that matters most here. It's how hardwood is priced and sold across the US and Canada. One board foot is a piece 1 inch thick, 12 inches wide, and 12 inches long - 144 cubic inches. The math is simple: thickness (in) × width (in) × length (ft), divided by 12. Our board feet calculator runs it for you, in imperial or metric.

The rest of the cluster covers the numbers around it. Price a lumber order by the board foot. Work out board and timber volume. Estimate wood weight by species. Figure how many plywood or MDF sheets a job needs. Account for saw kerf, plan rough-to-finished dimensions, and predict seasonal wood movement so panels don't split.

Every tool works in US and metric units, since results shift with species, moisture, and waste - treat them as planning estimates and confirm quantities with your supplier before a big order.
