bdft
A measurement of volume
Lumber
Thickness times width times length divided by 12 = bdft
Cost
bdft is how you caculate cost of lumber and logs
Estimate
Sawyers can estimate the project and you will know how much the lumber will cost.
Calculating Board Feet of Lumber Calculate bdft in logs
Hardwood and Softwood lumber that we use for framing, fencing, cabinetry and furniture is sold by the board foot. This is a measurement that is constant through all thicknesses of lumber, rather than applying to “one-by”, “two-by”, etc.
In the example piece of lumber below, the measurement “A” would be the thickness in inches , measurement “B” the width in inches, and measurement “C” the length in feet .
Thus, the formula for calculating the board feet of lumber in our
example would be;
‘A’ times “B” times “C” divided by 12 or;
For example if the piece if lumber was
3 inches thick (A)
8 inches wide (B)
10 feet long (C), we would have
3 x 8 x 10 divided by 12 = 20 board feet.
