Board Foot guide
Board Foot: Material Planning Guide
A board foot calculation produces a net geometric or quantity result, not a complete purchase order. Group pieces by thickness and width before totaling the order. Stock availability, cut sequence, fastening, finish build-up, waste, and whole-unit purchasing are recorded as separate decisions after the calculation is checked.

Board-foot work starts with the sawn or dressed cross-section actually being priced, then groups identical pieces before the invoice total is checked. Mixed hardwood batches, random widths, surfaced stock, and moisture-related dressing can all make the purchase tally differ from a simple nominal-size list.
The purchasing pass starts from the unchanged net result, then records available stock lengths, sheet orientation, package quantities, offcut reuse, breakage, field trimming, and spare material as separate adjustments. This preserves the difference between what the geometry requires and what the supplier must deliver.
- Group pieces by thickness and width before totaling the order. Keep the net result unchanged for review.
- List stock size, package size, waste, and spare material on separate lines.
- Round purchase quantities only after the available product is confirmed.
For this tool, the calculation method is board feet = thickness(in) × width(in) × length(ft) × quantity ÷ 12. The consolidated page keeps this topic beside the worked method, material checks, source boundary, and printable record.
