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 Footage (Doyle)=((D4)/4)²×L

Let's use the Doyle Log Rule formula to calculate the estimated board footage for a log with a diameter () of 10 inches and a length () of 17 feet:

Plugging in the values:

Board Footage (Doyle)=((10−4)/4)²×17

Board Footage (Doyle)=(6/4)²×17

Board Footage (Doyle)=(3/2)²×17

Board Footage (Doyle)=(9/4)×17

Board Footage (Doyle)=153/4

Board Footage (Doyle)=38.25

So, according to the Doyle Log Rule, the estimated board footage for the given log is approximately 38.25 board feet.

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