Free QR code generator for business cards and marketing

QR codes connect print materials to digital content. Learn how to create effective QR codes for business cards, flyers, menus, and campaigns.

Why QR codes work for marketing

QR codes bridge the gap between offline print materials and online content. A person scanning your business card QR code immediately visits your website, LinkedIn profile, or contact page — removing the friction of typing a URL. QR codes on packaging, flyers, menus, and in-store displays consistently improve engagement compared to printed URLs alone.

Best content for QR codes

  • Business cards: Your website or LinkedIn profile URL
  • Restaurant menus: Digital menu URL or ordering page
  • Event flyers: Registration or ticketing page
  • Product packaging: Product page, warranty registration, or tutorial video
  • Shop windows: Google Maps listing or catalog page

QR code size guidelines for print

For business cards, a QR code of 2.5cm × 2.5cm is the minimum for reliable scanning. For flyers and posters, use 4–6cm. Always test the printed QR code at its final size with at least two different smartphones before sending to print.

Tips for reliable QR codes

  • Use short URLs — shorter URLs make smaller, easier-to-scan QR codes
  • Ensure high contrast — dark code on a light background
  • Add a call to action like "Scan for menu" or "Visit our website"
  • Test on iOS and Android before finalizing
  • Keep the URL active — a broken link makes the QR code useless
