Calculate Board Foot Of A Log

The log length is the length to the last full foot especially for hardwood logs.

Calculate board foot of a log. It is sometimes important to calculate the board feet in an uncut log. Then divide the total by 144 for the total board footage of a given board. Since sawmills usually charge by the board foot this scale will help you determine the amount of lumber you will have and what you can expect your bill to be. A single board foot of lumber measures 1 inch thick 12 inches wide and 12 inches long.

Board feet is a measurement of the volume of lumber often used by wholesalers and sawmills in canada and the united states. Measure the diameter of the shorter end of the log not including bark in inches. By entering in the diameter inside the bark at the small end and the length the scaling techniques for international doyle and scribner are calculated and shown on the screen. The doyle rule estimates lumber recovery the number of board feet based on log diameter length residue and saw kerf.

Dont know what board feet are. Where those two measurements intersect you will find the board footage for that log. Estimate the number of board feet you can recover from a log using the doyle log rule. Find either a doyle rule or the international 1 4 inch rule table.

While it may seem confusing its actually pretty easy to calculate how many board feet of lumber. All the major log rules use the small end diameter inside the bark as the basic size measurement. Go here to find out. A single board foot is equivalent to 1 square foot of lumber that is 1 inch thick meaning it has a length of 12 inches a width of 12 inches and a thickness of 1 inch.

We also have a listing of the most common dimensions of lumber and their equivilent board foot measurement. The process must be repeated for each log. Log volume calculator diameter. How do you calculate the board feet in a log.

Simply input your dimensions and click calculate. If the log is not perfectly round then two readings are taken at 90 degrees to each other and averaged.
