Most B270 Sheets are 66.14 x 35.50.  Price per square foot is based on yields.  We can cut 12x12 parts, but the price will be more than the square foot price because we cannot utilize the full sheet.  If you would like a cut sheet at the square foot price, here are some suggested dimensions:

22.050 x 17.500 – yields 6 per sheet
16.535 x 11.833 – yields 12 per sheet
13.288 x 11.833 – yields 15 per sheet
11.833 x 11.023 – yields 18 per sheet
