Log Scaling Overview

Why We Scale

From an historical perspective, log scaling probably began around two hundred years ago – about the time of the Industrial Revolution. As sawmills arrived on the scene, it became necessary to have some means of log measurement. Log scaling was born.

In its simplest terms, scaling provides the means for establishing log value. Scaling gives an objective, quantifiable value for a log. The primary reason for scaling is to provide a basis for payment. Other reasons for scaling include:

• prediction of the quantity of end products
• check on the accuracy of cruise volumes
• basis for inventory measure
• basis for tax assessments
• written record of identification
• measure of work accomplished.

Scaling is defined as an arbitrary system of measurement, by means of a log rule, that reflects certain units of measure in a log. Predominantly, log scaling in Idaho is based on the Coconino Scribner decimal “C” log rule.
