Global Barcode Standards
Barcode standards play a crucial role in 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. Manufacturers must adhere to global barcode standards to ensure seamless communication and compatibility across different sectors. This article will discuss the importance of barcode standards for various 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 wide x 25 mm high.
The minimum recommended barcode size for an EAN-13 or UPC barcode is 80% of the standard size (approximately 30 mm wide x 20 mm high). 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 approximately 122 mm wide x 32 mm bar height (with 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 25-100%. When printing on corrugated cardboard, the ITF-14 should be over 62.5%.
The minimum bar height in a general distribution scanning 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 required space for a QR code depends on how much data is encoded and how large the scanning distance will be.
The practical minimum size for a QR code is 2 cm x 2 cm (0.8 inches x 0.8 inches) for close scanning environments, excluding the quiet zone.
The optimal size for a QR code depends on various factors, including the available space on the packaging, the scanning environment, print quality, and print process resolution. If a QR code is too small, it may be challenging for scanners to read, or it may not be printed in high quality and sufficient resolution. Conversely, a too large QR code may be difficult to scan from close up or print in good quality and resolution.
Barcode Colors:
Barcode scanners capture black or cool colors (blue, green) and ignore white or warm colors (red, orange, yellow). Therefore, it is essential to ensure that the barcode bars are printed in black or cool colors, and the background should be white or warm colors. Reflective surfaces or metallic colors do not scan well.
Barcode Position:
EAN-13 and UPC barcodes are typically positioned horizontally. If printing on a curved surface (e.g., a bottle), it is best to rotate the barcode 90 degrees so that it is vertical. Do not position the barcode near edges. Place it on a flat surface if possible and ensure that there is ample blank space around the barcode bars (at least 3 mm).
