Barcode standards are crucial for the efficiency and accuracy of supply chains, inventory management, and retail operations worldwide. These standards ensure that products can be easily identified and tracked throughout the supply chain process. Manufacturers must adhere to global barcode standards to ensure seamless communication and compatibility across various sectors. In this article, we discuss the importance of barcode standards for different barcode types (including EAN-13 and UPC barcodes) and how your business can comply with them.

What Are the Global Barcode Standards?

EAN-13 or UPC Barcodes:

The standard size of an EAN-13 or UPC barcode is 37 mm width x 25 mm height.

The minimum recommended barcode size for an EAN-13 or UPC barcode is 80% of the standard size (about 30 mm width x 20 mm height). This includes a 3 mm "quiet zone" (blank space) on the left and right sides of the barcode bars.

ITF-14 Carton Codes:

The standard size for ITF-14 carton codes (100% size) is about 122 mm width x 32 mm bar height (with a 10 mm quiet zone on the left and right sides).

The specified magnification range for an ITF-14 barcode symbol scanned in a general distribution environment is between 50% and 100%. For other scanning environments, the range is between 25% and 100%. When printing on corrugated cardboard, the ITF-14 should be above 62.5%.

The minimum bar height in a general distribution environment is 32 mm. In other scanning environments, the bar height should be as high as possible. 13 mm is the minimum bar height.

QR Codes:

QR codes do not have strict size standards. The size of a QR code depends on how much data is encoded and the required scanning distance.

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

The optimal size for a QR code depends on several factors, including the available space on the packaging, the scanning environment, the print quality, and the resolution of the printing process. If a QR code is too small, it may not be easily read by scanners or difficult to print in high quality and sufficient resolution. Conversely, if the QR code is too large, it may be challenging to scan at close range or print in appropriate quality or resolution.

Barcode Colors

Barcode scanners recognize black or cool colors (blue, green) and ignore white or warm colors (red, orange, yellow). Therefore, it is essential that barcode bars are printed in black or cool colors, and the background is white or warm colors. Reflective surfaces or metallic colors are difficult to scan.

Barcode Position

EAN-13 and UPC barcodes are usually positioned horizontally. If printing on a curved surface (e.g., a bottle), it is best to rotate the barcode 90 degrees to make it vertical. Do not position the barcode near edges. If possible, place it on a flat surface and ensure ample blank space (at least 3 mm) around the barcode bars.
