For example, a 4 x 4 has a thickness of 4 inches and a width of 4 inches. If the board is 10 feet long, that’s the length.
If you have multiple boards that are the same size, do the entire calculation for a single board and multiply it by the number of boards you need. For instance, if you have 20 boards that are 2 inches by 6 inches by 8 feet, multiply 2 by 6 by 8, which equals 96. Divide 96 by 12, which is 8 (the number of board feet in a single board of this size). Multiply 8 by 20, which is 160, to find the total board feet.
For example, say you have 1,500 board feet of lumber. If the boards are 3 inches thick, divide 1,500 by 3, which is equal to 500. So, 1,500 board feet is equivalent to 500 square feet.
You can find the Doyle scale table here: https://nfs. unl. edu/documents/ruralforestry/tree%20and%20log%20scale%20Doyle%20WEB. pdf Say the DBH is 22 and the height is 32 feet, or that there are 2 16-foot logs in the tree. Using the Doyle scale, you’d find that there are 295 board feet in the tree. Alternatively, say that the DIB is 35 and the log is 10 feet long. Based on the Doyle scale, the volume in board feet for the log is 601.
