QR Code Generator for Business Cards: Design & Contrast Rules

Learn the exact layout structures, size limitations, and margin constraints needed to place QR codes on business cards safely.

Perfecting business card layouts

Business cards have highly limited space. A printed QR code must be positioned cleanly on the back or in a dedicated corner, maintaining an adequate blank quiet zone border.

Size limits for business cards

Never print smaller than 1.5 cm × 1.5 cm. For high-density static codes, 2 cm × 2 cm is the recommended minimum to guarantee rapid scanning by older smartphones.
