Measurement
Calculate rough lumber volume in board feet from actual entered dimensions and quantity. Keep nominal-vs-actual size, surfacing loss, defects and project cut allowance visible instead of hiding them inside a guessed purchase total.
Change the defaults to match your project and the product you plan to buy.

At a glance
Planning estimate only. Verify product coverage, package size, supplier specifications and project requirements before purchasing.
Budget scenario
Use a current supplier subtotal or reuse a priced calculator result, then add optional delivery, tax and contingency. Home Measure Lab does not fetch or guess live prices.
Enter a current supplier subtotal or reuse a priced calculator result.
Budget values are local planning inputs, not live quotes. Verify tax treatment, delivery, labor and supplier pricing before purchasing.
Choose the right tool
You need lumber volume from entered board thickness, width, length and count using a board-foot pricing/takeoff basis.
It does not optimize a cut list or calculate rectangular sheet-goods nesting.
Methodology
thickness(in) × width(in) × length(ft) ÷ 12
Uses actual entered dimensions.
per-board board feet × board count
Keeps quantity visible.
base board feet × (1 + allowance)
Use a justified waste/selection reserve.
planning target × entered price per board foot
Supplier pricing basis can vary.
Record the actual thickness and width you intend to buy or the dimensions used by the supplier for board-foot pricing. Enter board length in the same basis as the order and separate different thicknesses or widths into separate calculations. If the project uses a detailed cut list, preserve that list because board-foot volume alone does not prove that the available stock lengths will yield the required parts.
Board-foot pricing is a volume convention, not a cut optimizer. Add reserve for defects, grain selection, end checks, matching or machining only when those conditions actually apply. If the supplier sells by the piece rather than by board foot, compare the board-foot total with the actual piece schedule before purchasing. For sheet goods, use Sheet Yield instead of treating plywood or panels as rough lumber.
Reference
| Input | Controls | Verify before using |
|---|---|---|
| Thickness + width | Board-foot volume | Use actual pricing dimensions. |
| Length | Volume per board | Separate unlike stock lengths if needed. |
| Count | Base board feet | Use the required piece schedule. |
| Allowance | Purchase target | Defects/cut selection remain explicit. |
Questions
One board foot is a lumber volume equal to 144 cubic inches.
Use the dimension basis used by the supplier or your project takeoff, and keep that basis consistent.
No. Board-foot volume cannot verify whether specific stock lengths yield all required parts.
