Enter NOMINAL sizes — board feet always use the nominal dimensions by trade convention (a 2x6 counts as 2 x 6 even though it dresses to 1.5 x 5.5 actual). Hardwood buyers: pick the quarters thickness (4/4 = 1", 5/4 = 1.25", 6/4 = 1.5", 8/4 = 2") to fill the thickness field. Leave the price blank when unknown.
| Item | BF each | BF total | Cost |
|---|---|---|---|
| 10 x 2x6 x 8 ft | 8 | 80 | $68.00 |
| Total | 80 | $68.00 |
BF = nominal thickness (in) x nominal width (in) x length (ft) / 12. Cost totals cover priced lines only. Net quantities — add your own waste factor before ordering.
| Nominal (in) | Actual dressed (in) |
|---|---|
| 1 | 0.75 |
| 2 | 1.5 |
| 4 | 3.5 |
| 6 | 5.5 |
| 8 | 7.25 |
| 10 | 9.25 |
| 12 | 11.25 |
Display-only reference (softwood, surfaced dry). Board feet ALWAYS use the NOMINAL dimensions — never substitute the actual dressed sizes into the BF formula.
