Global Barcode Standards
Barcode standards are crucial for the efficiency and accuracy of supply chains, inventory management, and retail processes 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 between different sectors. In this article, we discuss the importance of barcode standards for various barcode types (including EAN-13 and UPC Barcodes) and how your company 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" (white 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 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 scanning 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 at least 62.5%.The minimum height for the bars in a general distribution scanning environment is 32 mm. In other scanning environments, the bar height should be as tall as possible. 13 mm is the minimum bar height.
QR Codes:
There are no strict size standards for QR codes. The space required for a QR code depends on how much data is encoded and the scanning distance.
The practical minimum size of a QR code is 2 cm x 2 cm (0.8 inches x 0.8 inches) for tight 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 the resolution of the printing process. If a QR code is too small, it may be difficult for scanners to read or to print in high quality and sufficient resolution. Conversely, if a QR code is too large, it may be challenging to scan from a close distance or print with sufficient quality or resolution.
Barcode Colors
Barcode scanners detect black or cool colors (blue, green) and ignore white or warm colors (red, orange, yellow). Therefore, it is important that the barcode bars are printed in black or cool colors and the background is in white or warm colors. Reflective surfaces or metallic colors do not scan well.
Barcode Position
EAN-13 and UPC barcodes are usually placed horizontally. If printing on a curved surface (e.g., a bottle), it is best to rotate the barcode 90 degrees so it is vertical. Do not position the barcode too close to the edges. Place it on a flat surface if possible, and ensure there is sufficient white space around the barcode bars (at least 3 mm).
