The size of the barcode is known as magnification. Magnification can vary within certain limits, and if the barcode is not between these limits, it may not scan. It is the print quality of the barcode symbol that determines the minimum magnification you must apply, not a predetermined space on the packaging. It is recommended that you use a magnification higher than the minimum, in order to increase your barcode’s reliability.

Also take into consideration that the designer must allow sufficient space for the barcode, including a blank area called the ‘light margin’ or ‘quiet zone’ before the first bar and after the last bar, that enables the scanner to recognize the beginning and end of the barcode symbol. The light margin is included in our minimum size guides. But it is your printer who must advise you of the minimum barcode size that will be able to be printed on the product item. This is determined by measuring the ink spread (print gain) and the extent of variation on the ink spread during printing.

The size of the barcode may only vary within certain limits. Generally speaking, the barcode must be between 80 per cent and 200 per cent of the standard or 'nominal' barcode size, as shown. EAN.UCC barcodes should not be printed outside these limits as it can reduce their ability to be scanned.

Our size guides will guide you to the minimum area required and tolerances for standard magnifications.
