Name the dimension basis
Select actual, nominal, or supplier-billed values. The choice labels the tally but never changes a number.
A transparent tally for every board
Count board feet without hiding the dimensions used.
Choose actual measurements, nominal references, or supplier-billed dimensions, then enter each board row. LumberCalc uses the values exactly as written and applies board feet = cubic inches ÷ 144 in your browser. It does not save the tally, convert nominal sizes automatically, or judge grades, strength, logs, or supplier rules.

Three deliberate steps
Choose the basis before doing the arithmetic
Enter each board
Add thickness, width, length, quantity, and an optional label in imperial or metric units.
Review totals and copy
See row and total board feet, cubic feet, cubic metres, and optional quoted cost before copying.
Useful before money or material moves
Check a list while keeping its assumptions visible
- Prepare a mixed hardwood order from measurements taken in the workshop.
- Recalculate the arithmetic printed on a supplier quote without claiming the quote is commercially correct.
- Compare actual and nominal scenarios as separate tallies instead of relying on a hidden conversion.
Ready to tally
Use your dimensions, not an invisible assumption
Add only the rows you need, review the basis and rounded totals, then copy the tally without sending it to a server.
