Log Volume Calculator
Estimate log cubic feet, board feet, log scale yield, weight and value from diameter, length, count and species.
Board-foot output is an estimate. Local scaling rules, trim allowance, defects, bark, and contract terms can change payable volume.
Estimate log volume and board feet
For English searches, a log calculator usually needs diameter in inches, length in feet and board-foot log scale estimates. Use the result for planning, not as a substitute for the scaling rule in a timber sale contract.
Log scale caveats
- Doyle, Scribner and International rules can produce different board-foot values for the same log.
- Small-end diameter, bark, sweep, taper, defects and local rules affect sale volume.
- Use the rule required by the buyer, mill or forestry contract when money changes hands.
