Use the result as a planning estimate and verify project-specific dimensions and product information before ordering or cutting.
How it works
The calculator multiplies one board's volume and length by the number of pieces, then converts the totals to common lumber units.
total volume = thickness × width × length × quantityWorked example
Ten boards measuring 1 in × 6 in × 8 ft total 40 board feet and 80 linear feet.
Assumptions
- Dimensions are entered for one piece.
Limitations
- For purchasing, account separately for grade, defects, cut waste and available stock lengths.
