Tips for Better QR Codes

  • Keep data concise. Shorter content produces simpler QR codes that are easier and faster to scan, especially from a distance or on printed materials.
  • Test before printing. Always scan your QR code with at least two different devices to verify it works correctly before printing or distributing.
  • Use SVG for print. SVG files are vector-based and scale to any size without pixelation. Use PNG for screens and social media, SVG for posters and banners.
  • Maintain contrast. QR codes need high contrast between the dark modules and light background to scan reliably. Avoid placing them on busy or dark backgrounds.
  • Minimum print size. QR codes should be printed at a minimum of 2cm x 2cm (about 0.8 x 0.8 inches) for reliable scanning from a normal distance.
