How Big Should My EAN-13 Barcode Be?

The standard sizing of EAN-13 barcodes is around 38X25mm – this can be reduce to 80% of this size (30X20mm) and still be deemed officially acceptable. Furthermore if necessary it can be increased to 200% size as well (although this is uncommon). These sizings are particularly pertinent if you require barcode verification as this can determine whether or not your barcode passes. Regardless of this, if your barcode size is reduce too much (especially in width), there may be problems with the scannability of the code. Please test scan your barcode before use.
