How to svg qr codes for marketing and print campaigns: best practices
- Step 1Determine the minimum print size — Minimum size for arm's-length scanning (30–50cm distance): 2×2cm. For poster viewing at 1 metre: 3×3cm. For outdoor signage at 2 metres: 5×5cm. Larger is always better — a QR code that is too small is effectively invisible. SVG scales perfectly to any of these sizes.
- Step 2Write a clear call to action — Print a call to action above or below the QR code: 'Scan to book your free trial', 'Scan for the menu', 'Scan to see it in AR'. Without a CTA, scan rates drop significantly — people scan QR codes when they know what they'll get.
- Step 3Use error correction H for printed materials — Print materials get damaged, stained, and worn. Error correction H allows up to 30% of the QR code to be obscured and still scan. This is critical for packaging (which gets wet), outdoor posters (rain, sun damage), and high-traffic displays (physical wear).
Frequently asked questions
What is the ideal minimum size for a QR code on a business card?+
2×2cm (about 0.8 inches square) is the practical minimum for a business card QR code scanned at arm's length. Smaller codes can be printed but may fail to scan under suboptimal conditions (bright sunlight, cheap cameras). A 2.5×2.5cm code is safer and still leaves enough room for other business card content.
Can I print a coloured QR code on packaging?+
Yes, with important caveats. Ensure the foreground colour has at least 3:1 contrast against the background colour in every lighting condition the package will be seen in. Test scanning in direct sunlight (glossy packaging can create glare) and fluorescent retail lighting. Use matte finishes where possible to reduce glare.
How do I measure how many people are scanning my print QR codes?+
Use redirect URLs with UTM parameters: https://example.com?utm_source=flyer&utm_medium=print&utm_campaign=spring2026. Each unique QR code URL (one per campaign, per print format) lets you track scans in Google Analytics or your analytics platform. Never use a QR code in print without a trackable URL — you'll have no idea if the campaign worked.
Should I use a short URL or a long URL in a QR code?+
Short URLs create less complex QR codes (fewer modules) which scan more reliably and can be displayed at smaller sizes. They also let you update the destination after printing. The trade-off: short URL services can go offline. For mission-critical campaigns, use your own custom short domain (go.yourcompany.com) rather than a third-party service.
