All 1/8 thin woods are available in random widths and lengths and sold by the square foot. We cannot guarantee specific sizes, however if you require a specific size, please note the size in the Special Instructions box during checkout, we will fill your size requirements as close as possible. Calculating square footage: Square footage can be calculated with the following formula: Sq. ft. = Length (in inches) x width (in inches) divided by 144. Example: A board that measures 6" wide and 4 feet long would be calculated as follows: 6 x 48 =288 divided by 144 = 2. This board measures a total of 2 square feet.
