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 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
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.

When working with logs, estimating the total amount of usable lumber is essential for pricing, planning, and purchasing. A Log Board Foot Calculator helps determine the volume of wood in a log, ensuring accuracy in forestry, sawmilling, and construction.
Common Log Rules Used in Calculations
- Doyle Rule – Best for large logs; underestimates small logs.
- Scribner Rule – Offers a reasonable estimate for most logs.
- International 1/4″ Rule – Provides the most accurate estimate across various log sizes.
Why Use a Log Board Foot Calculator?
✅ Quickly estimate log volume before cutting.
✅ Reduce waste by knowing the exact yield.
✅ Compare log values based on different log rules.
✅ Make informed buying/selling decisions in the timber industry.
