FAQ
What size should my barcode be?
For reliable scanning, maintain a minimum height of 15mm and ensure adequate quiet zones (white space) on either side. The bar width depends on your scanner—most can read bars as narrow as 0.25mm.
Why is my barcode invalid?
Each format has specific requirements. EAN-13 requires exactly 12-13 digits, UPC-A requires 11-12 digits. Code 128 accepts any ASCII characters but others are more restrictive.
PNG vs SVG format?
Use SVG for print materials—it scales perfectly to any size. PNG is better for web, screen display, and when you need a specific pixel size.
