The following provides a guideline for the sizes in which you should print the barcode on your product, according to the ISO/IEC 15420 standard. This is very important if you require barcode verification. It is also a good guide for ensuring that your barcode scans correctly. If at all possible you should keep your barcode size within these standards. If you go outside these standards, you barcodes might be accepted by some retailers and rejected by others.
The specified magnification range for an EAN/UPC Bar Code Symbol being scanned at retail point of sale is 80% – 200% (X-dimension 0.26mm-0.66mm).
An allowable minimum magnification of 75% (X-dimension 0.25mm) is applicable only to on demand (e.g. thermal) print processes. In this case, the bar height should never be truncated below the minimum required height for an 80% magnification barcode symbol.
Where an item may also be scanned in a General Distribution Scanning environment (automated scanning), the allowable magnification range is 150% to 200% (X-dimension 0.50mm – 0.66mm).
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 acceptable provided the digits are clearly legible.
Dimensions (All measurements in millimetres)
|Magnification||X-dimension||Width||Bar height||Left Quiet Zone||Right Quiet Zone|
– 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. It is a good idea to allow for more quiet zone space than is strictly required in case of ink spread or printing inaccuracies
If you need barcode packages (with the images, certificate of authenticity & registration), please use the following links: EAN-13 Barcodes Package, UPC-A Barcodes Package, CD Barcodes Package, DVD Barcodes Package, ISBN Book Barcodes Package and ISSN Magazine Barcodes Package.
We also recommend you to register free your product info in IBNREG – International Barcodes Network Registry, which will allow your customers to find the product info before buying it, by scanning the barcode with the Zebra Barcode Scanner application.
