Here is a board foot calculator for figring your lumber requirements. Enter your desired thickness, width, length, and quantity, and click 'Compute'.
Hardwood lumber is typically sold by the 'board foot', a unit
of volume equivalent to 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
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.
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.
