Check barcode label size before you print a batch.

Estimate quiet-zone, DPI, X-dimension, and label-fit risks for Code 128, UPC-A, and EAN-13 labels. This is a local print-risk checklist, not a barcode verifier or certification tool.

Reprint checklist

  1. Use Code 128 with the entered dimensions.
  2. Print at 100% scale with no fit-to-page resizing.
  3. Keep text, borders, and artwork out of the quiet zones.
  4. Print one label first and scan it with the actual checkout or inventory scanner.
  5. Use a hardware barcode verifier when certification or retailer compliance is required.
