Sheet Yield & Kerf

A cut is not a line, it's a gap. See how many strips a sheet really yields once every kerf is counted.

Home › Calculators › Sheet Yield & Kerf

Enter a sheet length, a strip width and your saw's kerf, then press Calculate.
From the book — Chapter 2. n = floor((length + kerf) ÷ (width + kerf)) — every cut after the first eats one more kerf's worth of the sheet.
