Try the calculation

Example inputs · U.S. customary / metric input

One nominal 2 × 4 × 8 ft board. This example uses nominal board measure. Choose actual dimensions for measured physical volume.

Input and setup notes

All board groups share one unit system and dimension basis. A unit switch converts the entered dimensions.

Actual uses measured dimensions for physical volume. Nominal uses entered trade sizes; for softwood, that is nominal board measure, not physical volume. Hardwood tally conventions may differ.

Example: 2 in.

Example: 4 in.

Example: 8 ft.

Example: 1 board.

Before you calculate

Board-foot results depend on the dimensions and transaction basis you use. Keep nominal and actual sizes separate, and do not treat a geometric total as a seller’s tally without checking the quote.

Understand lumber dimensions

Lumber measurement guides

  • How to calculate board feet

    Turn board measurements into a lumber total you can check. Learn which dimensions to enter, how to combine different sizes, and how to allow for milling without counting the same material twice.

  • Nominal vs. actual lumber dimensions

    Use a lumber label to identify the product, then choose the dimensions your calculation needs. Compare common dry surfaced softwood sizes and follow examples that separate physical volume, trade tally and whole-board purchasing.
