Doyle’s Rule

Doyle’s Rule​

Doyle’s Rule is widely recognized for its simplicity and practicality. The formula approximates the volume of usable lumber in a log, accounting for losses due to saw kerf and taper. It’s particularly useful for larger logs but may underestimate the yield from smaller logs.

Scribner’s Rule

Scribner’s Rule​

Scribner’s Rule provides a more detailed estimate based on a diagram of lumber that can be cut from a log. It is most accurate for logs of moderate size but can overestimate yield for smaller logs and underestimate for very large ones.

International 1/4-Inch Rule

International 1/4-Inch Rule​

The International 1/4-Inch Rule is known for its precision and is considered more accurate across a range of log sizes. It accounts for saw kerf and assumes a consistent taper along the log.
