7 Best Practices for Designing QR Codes That Convert

1. Add a Clear Call-to-Action (CTA)

Codes with an explicit CTA (“Scan to get 20% off”) lift scan rates by up to 80 %. Use a frame or short text directly beneath the code so users know why they should scan.

2. Size It for Distance & Add a Quiet Zone

The absolute minimum print size is 2 × 2 cm (0.8 × 0.8 in), but specialists recommend ≥ 1 inch for close scans and ≥ 2 inches for posters viewed from several feet. Always keep a 4-module “quiet zone” around the code so scanners can isolate it.

3. Maximize Color Contrast

Maintain dark foreground modules on a light background; inverted palettes cause mis-reads on some phones. High-contrast pairs (e.g., navy on white) improve first-attempt scans by 30-40 %. Minily lets you fine-tune both foreground and background hues while preview-testing instantaneously.

4. Brand With a Logo—Carefully

Embedding your logo boosts trust, but keep it under 30 % of the code area and never obstruct finder patterns (the three big squares). Scanova tests show well-placed logos can increase engagement by up to 50 % without harming readability.

5. Choose Dynamic Codes for Flexibility & Tracking

Dynamic QR codes let you update the destination URL and collect real-time metrics—ideal for A/B tests and seasonal promos. Minily’s free link analytics layer pairs each dynamic code with click-through data, device breakdowns and geographic heatmaps.

6. Test Across Devices & Environments

Before publishing, scan on at least three phone models and in varied lighting; 20 % of failed campaigns trace back to inadequate testing. Minily’s dashboard logs real-time errors so you can react instantly.

7. Measure, Learn & Iterate

High-performing teams revisit their QR code analytics weekly, tweaking CTAs, colors or landing pages based on conversion data. Minily’s Engagement Overview compares your current metrics to previous periods and moving averages—free, unlimited and ready out of the box.
