Instructions: Log Volume Calculator

All the major log rules use the small end diameter, inside the bark, as the basic size measurement. If the log is not perfectly round, then two readings are taken at 90 degrees to each other and averaged.

The log length is the length to the last full foot (especially for hardwood logs). Do not round up to the next foot. Any inches entered will not be considered in the calculation. Softwoods are often measured to the last full even foot (i.e., 8, 10, 12, etc.).
