The basic calculation for board feet is: Thickness x Width x Length / 12 = Board Feet. 2 x 4 x 10 / 12 = 6.667 Board Feet. A 2 x 10 -16′ has 26.67 board feet: 2 x 10 x 16 / 12 = 26.667 Board Feet. PCS x T x W x L / 12 = Board Feet. 84 x 2 x 8 x 12 / 12 = 1,344 Board Feet. 1.25 x 6 x 14 / 12 = 8.75 Board Foot.
How do you calculate board feet in lumber?
To estimate the board feet from a log, measure the average diameter of the smaller part of the log in inches. Then, measure the length of the log in feet. Move the scale’s marker over to where these two measurements meet. Where the two measurements intersect is the approximate board foot output.
How many board feet are in a 10 2×4?
A 2x4x10 board has 6.66667 total board feet in it: the board foot factor (BFF) of a 2×4 is 0.666667. Multiply 0.66667 by the length of 10 which gives total board feet of 6.66667.

How do you calculate board feet for a project?
To determine board feet for your project, take the desired board’s thickness, width and length, and multiply them together. From there, you need to divide it by 144 to determine the number of board feet you need.
How do you calculate board feet in inches?
How do you measure a board foot? Take a rectangular piece of lumber. Measure the length of it in feet, rounding to the nearest decimal place. Measure the width in inches. Measure the thickness in inches. Multiply all three numbers together and divide by 12.
How do I calculate board feet in Excel?
Here is the relation: 1 board foot = 144 cubic inches = 1/12 cubic foot. Board foot formula = length * width * thickness. board foot = length(ft) * width(in) * thickness(in) / 144. board foot = length(ft) * width(ft) * thickness(in) / 12.

How is timber measured?
The length of a piece of timber should be measured with a tape following the curvature of the log. The total height of a standing tree is the vertical distance from the base of the tree to the uppermost point (tip). The total height of felled trees is the straight line distance from the base to the tip.
How do you calculate square feet for wood?
Step 1: Measure the width of your item in inches and then multiply times the height. Step 2. Multiply the width and height of all sides to be coated (including the top). Step 3: Add all of these totals together and divide by 144 to determine the total square feet you will need to cover.
How do you calculate board feet in a tree?
The board-foot content of any board may be determined by multiplying the length by the width by the thickness, all expressed in inches, and dividing by 144 cubic inches. The board foot is also the most common volume measure for trees and logs to be used for lumber and veneer.
What length do you cut logs for lumber?
Find yourself a nice and straight stick, preferably green and hard like oak or ash. Use a tape measure and cut the stick to either 4 feet or 6 feet exactly. I like to use 4-foot-long sticks because most log lengths are divisible by 4 feet. Mark the stick by cutting a groove in it at 2-foot increments.
How do you find the diameter of a log?
The “Diameter of Log” scale on the top of the opposite side of the stick is a ruler that can be used to check this distance. Make a mental note of the bend in your arm when the stick is 25 inches from your eye. For accurate diameter measurements, it is critical that the stick is 25 inches from your eye.
