Choose the Right Format
Use EAN-13 or UPC-A for retail products, Code 128 for general purpose, and ITF-14 for shipping cartons. Using the wrong format may prevent scanners from reading your barcode.
Maintain Quiet Zones
Always keep adequate white space (quiet zones) on both sides of the barcode. This helps scanners identify where the barcode begins and ends. Use a margin of at least 10px.
High Contrast Colors
Dark bars on a light background work best. Black on white is ideal. Avoid red bars as most laser scanners use red light and cannot read them. Blue and green bars work well.
Don't Scale Too Small
Ensure your barcode is large enough to be reliably scanned. Minimum recommended size varies by format, but generally keep the height above 15mm and maintain the original aspect ratio.
Use SVG for Print
When printing barcodes, always use SVG format. Unlike PNG, SVG barcodes can be scaled to any size without losing quality, ensuring crisp bars at any resolution.
Test Before Printing
Always test your barcode with a scanner before printing in bulk. Print a sample and verify it scans correctly with the equipment your system uses.
