Here is a bare-bones board foot calculator for tallying up lumber
requirements. Just enter your desired thickness, width, length, and
quantity and it will compute board feet and total board feet. Nice and
simple. If you want something a little more elaborate that can also
produce a materials list, check out the
Tabulator.
Notes:
1. Hardwood lumber is typically sold by the
board foot, a unit of volume equivalent to a board that is one inch
thick, one foot wide and one foot long, or 144 cubic inches. Lumber
thickness is expressed in quarters of an inch, beginning with 1 inch, so
that 1 inch lumber is designated as 4/4, 1-1/2 inch lumber is 6/4, 2
inch lumber is 8/4, and so on. These units refer to nominal or roughsawn
dimensions, not surfaced dimensions.
2. This program rounds lumber thickness up
to the next 1/4" and lumber less than 4/4 is rounded up to 4/4.
Thus, a specified thickness of 3/4" will be treated as 4/4" material.
3. You can enter fractional wood dimensions as
decimals (12.75), or as conventional fractions (12 3/4). If you use
fractions, just make sure you leave a space between any leading whole
number and the fraction.
