Barcode standards are vital for ensuring the streamlined operation of supply chains, stock control, and retail activities around the globe. These regulations help products be efficiently identified and tracked through every step of the supply chain. Producers need to follow these universal barcode norms to guarantee smooth interaction and compatibility across various industries. This article will delve into the significance of barcode standards for different barcode types (including EAN-13 and UPC barcodes) and guide your business on how to adhere to them.

What are the Global Barcode Standards?

EAN-13 or UPC barcodes:

The standard size for an EAN-13 or UPC barcode is 37mm in width and 25mm in height.

The minimum recommended size for an EAN-13 or UPC barcode is 80% of the standard dimensions (around 30mm in width and 20mm in height). This also includes a 3mm "quiet zone" (blank space) on both sides of the barcode.

ITF-14 Carton Codes:

The standard dimension for ITF-14 Carton Codes (100% size) is approximately 122mm in width by 32mm in bar height, with 10mm quiet zones on both sides.

The designated magnification range for an ITF-14 Barcode Symbol in a General Distribution Scanning setting is between 50% and 100%. For other scanning environments, the range is 25% to 100%. If printing onto corrugated cardboard, the ITF-14 should be above 62.5%.

The minimum bar height for a General Distribution Scanning Environment is 32mm. In other scanning settings, the bar height should be maximised. The minimum bar height is 13mm.

QR Codes:

QR Codes do not have stringent size requirements. The required space for a QR code depends on the amount of data it holds and the distance from which it will be scanned.

The practical minimum size for a QR code is 2 cm by 2 cm (0.8 inches by 0.8 inches) for close-range scanning, excluding the quiet zone.

The optimal size for a QR Code is influenced by several factors including available packaging space, scanning environment, printing quality, and print resolution. If a QR Code is too small, it may be challenging to scan or print with high quality. Conversely, if it is too large, it may be difficult to scan at close range or print adequately.

Barcode Colours

Barcode scanners detect black or cool colours (blue, green) and ignore white or warm colours (red, orange, yellow). Therefore, it's essential to print barcode bars in black or cool colours, while the background should be white or warm colours. Reflective or metallic surfaces are not ideal for scanning.

Barcode Position

EAN-13 and UPC barcodes are generally placed horizontally. When printing on curved surfaces (like a bottle), it's best to rotate the barcode 90 degrees so that it's vertical. Avoid positioning the barcode close to any edges. It should be on a flat surface with at least a 3mm blank space around the bars.
