Your kerf estimate

Green outlines: cut. Terracotta guides: score or mark only after assigning that operation in your software. A colour alone does not set an operation. PDF: black cut and score outlines at the stated physical size. Print at actual size on a sheet large enough for the page.

What the output means

For a square cut with no compensation, commanded outside width minus measured cut-out width estimates kerf. It does not establish a safe bridge, gap or piece size. Enter your own threshold in the checker.
