, but 6 feet, 10 feet, and 12 feet are also available.

Dimensional lumber is lumber that has been
cut to a specific size (and shape)
for use in a construction project.
Cut to standard sizes
identified by its nominal size
are the size of the board when it is first cut from a tree
is the size of the wood once it is dried (either air-dried or kiln-dried) and planed
There are two types of identifiers you will see with hardwood lumber:
The thickness denoted by 4/4, 6/4, 8/4, etc.
The number of planed sides denoted by S1S, S2S, etc.
What is a board foot?
A board foot is a unit of measurement based on the volume of the wood.
The base unit for calculation is a board that is
1″ x 12″ x 12″.
1 x 12 x12 = 144 cubic inches or 1 board foot.
Plywood sheets are available in thicknesses ranging from
⅛″ all the way to 1″.
