Why is proper size specification important?

  • You need to know what size to print the barcode on your product.
  • Correct size ensures that the barcode scans correctly.
  • Correct size is especially important if you need barcode verification.
  • If you don’t keep within the size specifications, some retailers may reject your barcodes.


Below are the ITF-14 Barcode Specifications in millimetres. This page shows the officially allowed sizes of your ITF-14 Barcode on your carton

The top and bottom bearer bars are mandatory whereas the vertical bearer bars are optional provided a printing method is being used that doesn’t require printing plates.


The specified magnification range for an ITF-14 Barcode Symbol being scanned in a General Distribution Scanning environment is between 50 and 100%. For other scanning environments the range is 25-100%

If printing onto corrugate fibreboard the ITF-14 should be above 62.5%.

Height of Bars:

The minimum height for the bars in a General Distribution Scanning Environment is 32mm.

In other scanning environments the bar height should be as high as possible. 13mm is the minimum bar height, hence all ITF-14’s should exceed this height however every effort should be made to ensure that the height is as close as possible to 32mm.

Bar Width Ratio:

The bar width ratio is 2.5:1. The acceptable range for this ratio is between 2.25:1 and 3:1.
