Please Note: 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.
