Board Foot Calculator
Multiply thickness in inches by width in inches by length in feet and divide by 12 to get board feet per piece, then multiply by the piece count and your price per board foot for the total cost of the order.

Method and assumptions
Figur turns your measurements into purchase quantities with standard geometry: it computes the area, length, or volume, applies the waste or spacing you enter, and rounds up to whole purchase units. Everything is calculated locally in your browser.
- Purchase quantities round up to whole units (sheets, bundles, boards, bars, or packages) because suppliers do not sell fractions.
- Assumed coverages and package sizes (for example, 3 bundles per square or 4×8 sheets) are common conventions; verify your product label and supplier.
- The waste percentage is applied exactly as entered; complex cuts, patterns, and damage can require more.
- The result does not replace your field measurements, plans, or local code requirements.
This tool provides a planning takeoff, not a binding bid, structural design, or engineering advice. Confirm quantities with field measurements, your supplier, and the applicable professionals before buying.

Frequently asked questions
What exactly is a board foot?
A board foot is a lumber volume unit equal to a piece 1 inch thick, 12 inches wide, and 1 foot long — 144 cubic inches. It is the standard way hardwood and rough lumber are priced.
Should I use nominal or actual dimensions?
Rough lumber is usually tallied at nominal dimensions, while surfaced boards measure smaller. Enter whichever dimensions your supplier bills by so the cost matches the invoice.
