Dimensional Lumber

Dimensional lumber refers to the standard sizes of lumber that are manufactured and purchased commercially. Wolfram|Alpha uses data and formulas to determine the sizes of standard lumber. Lumber mills manufacture standard nominal sizes of dimensional lumber based on both width and thickness. Length can also be a factor. After the lumber dries and is planed, its actual dimensions are smaller. Calculate how much lumber can be obtained from a log of a known size based on standard formulas from the lumber industry.
Dimensional Lumber

Determine the nominal and actual dimensions of standardized lumber by specifying a board size, or find the volume of lumber obtained from a log by using one of several formulas.

Specify a basic softwood lumber size:

2x4 lumber

Include length and/or wood type:

4x4x12 lumber
2 x 6 x 12 yellow pine

List available softwood lumber sizes:
