About the scaling rules
Doyle Scale
The standard in Appalachia and most of the Eastern US. Underestimates small-diameter logs but remains the most widely used rule for buying and selling hardwood logs in Kentucky, Ohio, West Virginia, and surrounding states.
Scribner Scale
Common in the Pacific Northwest and some Midwestern mills. More accurate than Doyle for small logs. Based on diagrams of circles packed into a square, approximating the board yield of a log.
International 1/4"
The most accurate of the three rules. Accounts for taper at 1/4" per 4-foot section. Often used by foresters, timber cruisers, and government agencies for appraisal purposes.
