Multiply all 3 measurement together, i.e. Formula to calculate board feet = (Thickness × Width × Length) ÷ 12. There are 5 board feet in a 2x3x10 dimensional board. In this case, 48 ÷ 12 = 4, so you need 4 board feet of lumber. To finish the calculation, just divide by 12. There are 4 board feet in a 2x2x12 dimensional board. In this case, 120 ÷ 12 = 10, so you need 10 board feet of lumber. There are 10 board feet in a 3x4x10 dimensional board. In this case, 144 ÷ 12 = 12, so you need 12 board feet of lumber. There are 12 board feet in a 2圆x12 dimensional board. Formula to calculate board feet = (Thickness × Width × Length)÷ 12. There are 10 board feet in a 2圆x10 dimensional board. In this case, 89 ÷ 12 = 6.66, so you need 6.66 board feet of lumber. There are 6.66 board feet in a 2x4x10 dimensional board. In this case, 64 ÷ 12 = 5.33, so you need 5.33 board feet of lumber. There are 5.33 board feet in a 2x4x8 dimensional board. In this case, 80 ÷ 12 = 6.66, so you need 6.66 board feet of lumber. There are 6.66 board feet in a 1x10x8 dimensional board. In this case, 100 ÷ 12 = 8.33, so you need 8.33 board feet of lumber. There are 8.33 board feet in a 1x10x10 dimensional board. There are 5.33 board feet in a 1x8x8 dimensional board. There are 4 board feet in a 1圆x8 dimensional board. In this case, 192 ÷ 12 = 16, so you need 16 board feet of lumber. There are 16 board feet in a 4x4x12 dimensional board. Formula for board feet How many board feet are in a 4x4x12? If length are in inches for small board, then you divide the total by 144.Ģ) Bd ft = (T” × W” × T”)/ 144. Formula to calculate board feetįormula to calculate board feet, if thickness of a board in inches, width in inches and length in feet, then multiply 3 all measurements together and then divide by 12 to get total board feet. In this case, 60 ÷ 12 = 5, so you need 5 board feet of lumber. If length are in inches for small board, then you divide the total by 144.įor example, how many board feet are in a 1圆x10?, formula to calculate board feet = (Thickness × Width × Length) ÷ 12.

4) Divide the result by 12, to get your total Board.3) Multiply the thickness in inches by the width in inches by the length in feet.
