Actual board thickness. Board-foot math uses actual dimensions unless you intentionally enter nominal sizes.
in
Actual board width.
in
Board length.
ft
Number of identical boards.
boards
Extra board feet to buy for defects, trimming, kerf, layout or sorting.
%
Cost per board foot for the lumber.
$/bd ft
Optional load-planning density preset. Species does not change board feet; it converts the buy volume into an approximate weight.

Method notes 4 notes
  • Board feet use actual entered dimensions: thickness in inches x width in inches x length in feet / 12.
  • Species does not change board-foot volume; it only converts the buy volume, including waste, into an approximate load weight.
  • Species preset: Red oak. Presets are screening values near air-dry stock; measured density is better for payload or shipping work.
  • Nominal lumber sizes, rough-sawn oversize, shrinkage, grading defects and cut-list yield can change what you need to buy.
