EAN-13 Size Standards
The GS1 standard specifies a minimum EAN-13 barcode size of approximately 37.29 mm wide and 26.26 mm tall at 100% magnification. Reducing below 80% magnification may cause scan failures at checkout systems. Plainscan automatically generates EAN-13 barcodes at dimensions suitable for professional retail printing.
