Log Rules & Scale Sticks for Timber Volume Measurement
Log rules and scale sticks are essential tools for measuring log volume in the timber industry. Available in Scribner, Doyle, and International log rule formats, our scale sticks allow timber buyers, log scalers, and mill operators to quickly estimate board-foot volume for individual logs and log decks. Accurate log scaling is fundamental to fair timber sales and efficient sawmill operations.
Use log rules alongside diameter tapes, increment borers, and calipers for a complete timber measurement toolkit. Our forestry and logging supplies include a full range of measurement tools for timber cruisers, log buyers, and forest managers. Record measurements in field books and use tallying supplies for efficient scaling operations.
Frequently Asked Questions
What log rule scales do you carry?
We carry log rules in Scribner, Doyle, and International (1/4 kerf) scales. The appropriate scale depends on regional standard — Scribner is most common in the West, while Doyle is prevalent in the South and East for logging operations.
How do I use a log scale stick?
Place the scale stick across the small end of the log, read the diameter, then use the rule to find board-foot volume based on log length. Use a diameter tape for more precise diameter measurements in timber scaling.
What is the difference between log rules?
Scribner overestimates small logs and underestimates large ones. Doyle is more accurate for large logs but penalizes small logs. International is the most mathematically accurate rule. Regional timber markets determine which rule is standard for log scaling transactions.
