Quiet zone (margin) rule # Always keep a blank border around the QR code. Minimum is 4 modules (the small squares) on all sides. Cropping the margin is the #1 reason printed QRs fail.
Contrast rule # Best: dark QR on white/light background. Avoid: light QR on dark background (some scanners still struggle). Avoid: low contrast (gray-on-gray), metallic ink, glossy reflections. Background rule # Do not place QR on busy patterns, photos, gradients, or textured paper. If you must, put a solid light “plate” behind it (including the quiet zone). Logos and fancy shapes? # Logos in the center can work, but they reduce effective error tolerance. If you add a logo later, print bigger and test more devices.
Fast checklist # Dark on light Keep quiet zone Use SVG for print Test iPhone + Android Use 20-25 mm (0.8-1.0 in) for most business cards. Includes minimum size guidance for short URLs, larger sizing for vCards, quiet zone rules, and a card dimensions chart.
