EAN-13 Specifications

Recommended Print Sizes

This guideline helps you determine the correct print size for your EAN‑13 barcode. It plays a key role in barcode verification and provides a solid reference for ensuring your barcode scans correctly.

Keep your barcode size within these standards whenever possible.
>Otherwise, if you go outside these limits, some retailers may accept your barcode, but others will reject it.
>Therefore, staying within the recommended range gives you the best chance of universal acceptance.

Minimum Magnification Rules

Scanning Environment Magnification Range X‑Dimension Key Rule
Retail Point of Sale (standard) 80% – 200% 0.26mm – 0.66mm This is the specified range for retail checkout scanning.
On‑demand (thermal) printing 75% minimum (special case) 0.25mm Only applies to thermal print processes. Do not truncate bar height below the minimum required for an 80% magnification symbol.
General Distribution (automated scanning) 150% – 200% 0.50mm – 0.66mm Use this larger size for automated warehouse or conveyor scanning.

Quiet Zone & Printing Tips

Furthermore, it is a good idea to allow for more quiet‑zone space than strictly required. This is because ink spread or printing inaccuracies can occur, so the extra space acts as a buffer.

Human Readable Interpretation

The Human Readable Interpretation should be printed beneath the bar code symbol.

The recommended typeface for the Human Readable Interpretation is OCR-B at a height of 2.75mm at nominal size (100% magnification, X-dimension 0.33mm). This typeface is a recommendation only and alternative type fonts and character sizes are acceptably provided the digits are clearly legible.

Terms:

– Bar Width = width of barcode symbol excluding Quiet Zones

– Bar Height = height of bar excluding guard bar patterns

– Quiet Zone = Area of white space on either side of the bars

 Always provide extra quiet zone space beyond the minimum requirements to account for potential ink spread or printing

ITF-14 Specifications

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

ITF-14 Sizing

 

 

 

</p>

 

 

 

 

 

 

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.

Magnification:

In a General Distribution Scanning environment, you must magnify ITF-14 Barcode Symbols by 50% to 100%. For other scanning environments the range is 25-100%

If printing onto corrugate fibreboard to 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.

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.

Human Readable Interpretation:

Font, font size and location are not specified here.  Print them clearly in proportion to the rest of the barcode. Fonts can appear below the barcode.

Add space for the quiet zones than the minimum in case of ink spread

Terms:

General Distribution Scanning Environment – This refers to automated scanning by a machine as the item passes along a conveyor belt.

Other Scanning Environments – Typically this refers to handheld scanners.

Bar Width Ratio – this refers to the ratio of wide modules to narrow modules in the ITF-14. A wide module should be 2.5 times the width of a narrow module.

Quiet Zones – Area of white space on either side of the bars
