How do you find the board feet in a round log?
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.
What is the formula for board foot calculation?
Board footage is calculated by multiplying the nominal thickness in inches (T) by the nominal width in inches (W) by the actual length in feet (L) and dividing by 12. The formula is: T x W x L = Board ft.
How many board feet of lumber are in a log?
How Much Lumber is in a Log?
| The board-foot contents of logs according to the International 1/4 Rule | ||
|---|---|---|
| Diameter of log small end, inside bark | Length of log (feet) | |
| 16 inches | 85 | 130 |
| 17 inches | 95 | 150 |

How many board feet are in a 2x4x10?
6.66667
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 many board feet do I need?
TIP: To calculate board feet: rough standard thickness X actual width X actual length divided by 144. Use the thickness of the material you intend to start with, not end with. For example, the 3/4″ top will start from 4/4 lumber.
What is the Doyle rule?
The Doyle Rule (Table 1) is the most widely used rule, especially on private timber in the east and south. The formula is simple and easy to remember. Board Feet Doyle = (D-4)2 x (L/16) D = Diameter inside bark at the small end in inches. L = Log length in feet.
What is the first step in solving board foot?
Calculate Board Feet with Board Feet Formula
- First, measure the length of the board in feet.
- Next, measure the width of the board in inches.
- Then, measure the count (board thickness) in quarters of an inch.
- Next, multiply width (inches) x length (feet) x count.
- Finally, divide the result by 12.
How many trees does it take to make 1000 board feet?

|---|---|---|
| Dbh (inches) | Number of 16-Foot Logs | |
| 34 | 300 | 1,000 |
| 36 | 350 | 1,140 |

How many board feet are in a 2x4x14?
9.33333
A 2x4x14 board has 9.33333 total board feet in it: The board foot factor (BFF) of a 2×4 is 0.66667.
How do I calculate how much timber I need?
You can measure board feet by multiplying length x width x thickness in inches, and then dividing by 144. If ordering a large amount by board feet, just multiply the total board feet needed by the price per board foot for the total cost.
How do you calculate board feet in lumber of a tree?
Tree Volume Estimation 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 is the Scribner rule?
The Scribner rule is an intermediate estimator of lumber volume for logs less than 28 inches in di- ameter and less than 16 feet in length. Its inaccuracies come from the lack of allowance for log taper and a uniform slab allowance for different log diameters.
How does board foot pricing work?
Hardwoods are sold by the board foot, which is a calculation of the wood volume in the board. A board foot indicates a volume quantity equal to a board 12 inches by 12 inches by 1 inch, or one-twelfth of a cubic foot.
How much board feet do I need?
How do you use the log board feet calculator?
The log board feet calculator utilizes log rules calculations. 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.
How do you calculate the cost of a board foot?
board feet = length(ft) * width(in) * thickness(in) / 12. board feet = 8 * 10 * 1.25 / 12. board feet = 8.33 BF. Now, multiply this result by the number of pieces to obtain the total board footage of your purchase: 5 * 8.33 = 41.67 BF. Finally, you can multiply this value by the price per board foot to determine the total cost of your purchase.
How do you value a log for lumber?
In order to put a value on a log, you need to estimate the board yield after it comes back from the timber mill. Most commonly in the US and Canada, that’s expressed in board feet, the volume equivalent to a 1″ x 12″ x 12″ wide board. ( Other volume measurements sometimes include cords and cubic feet).
How many cubic feet is a board foot of lumber?
By definition, one board foot of lumber is one square foot that is one inch thick. If you would like to convert regular volume units into board feet, use the following relation: 1 board foot = 144 cubic inches = 1/12 cubic foot How to calculate board feet?
