Log Board Foot Calculator

how much lumber can you get from your trees?

"Board feet" is a unit of measurement for lumber, equal to one square foot of wood that is one inch thick. "Log board feet" is a measure of the amount of usable lumber that can be obtained from a log, calculated by multiplying the log's diameter and length by a "scaling factor" that takes into account the log's taper and defects. Log board feet can be used to estimate the value of a tree or a group of trees before they are harvested.

Our Calculations are using the Doyle Rule for measuring board-feet

The Doyle rule for measuring log board feet is a method used to determine the volume of a log in board feet. It is based on the formula:

Board feet = (Diameter at small end (inches) x Diameter at small end (inches) x Length (feet)) / 16

The diameter is measured at the small end of the log, and the length is measured in feet. The result is then divided by 16 to get the total board feet. This method is commonly used in the lumber industry and is considered to be one of the most accurate ways to measure the volume of a log.

While the Doyle Rule is not 100% accurate, it is the commonly accepted method of measuring board-foot.
