The single most common QR code: paste a URL, get a code, print it. No login, no redirect through some marketing platform that breaks next year. The code points where you say, and only where you say.
Dynamic QR codes (the kind that point at a third-party redirect) let you change the target later — but you pay a monthly fee, the redirect provider can shut down, and they often track every scan. Static QRs (what Zen QR makes) point directly at your URL. As long as your URL exists, your QR works.
QR codes scale module density with URL length — a long URL becomes a denser, harder-to-scan code. Use the shortest stable URL you control: example.com beats example.com/landing-page-summer-2026. If you need rotation, host a redirect on your own domain.
Print at least 2cm × 2cm (~0.8") for close-range scanning. For posters viewed from 2 meters away, scale to 10cm × 10cm or more. Always leave a quiet zone (margin) of at least 4 modules — the white space around the code is part of the standard. Avoid printing on glossy surfaces in bright light.
Scan the printed proof with two or three different phones before doing a large run. Different camera apps have different tolerance for color, contrast, and damage — what scans fine in iPhone's Camera might fail in an older Android scanner. Test, then print.
Use HTTPS. Use the shortest stable URL you control — example.com beats example.com/landing-page-summer-2026 for QR density and for memorability.
If you might need to change the destination later (event link, campaign URL), point the QR at a redirect URL on your domain and change the redirect server-side. Static QR + your redirect = poor man's dynamic QR.
Default 512 px is fine for screens. For posters and packaging, go to 1024 or 2048 px so the SVG/PNG holds up at large physical sizes.
Scan the proof with iOS Camera and a generic Android QR reader. If both work cleanly under normal indoor light, you're safe to print at scale.
Add a redirect on your domain that logs the hit, then redirects. You get scan counts, the customer keeps speed and trust, and you don't share data with a third-party QR analytics service.
From poster to landing page in one scan — drastically higher click-through than a typed URL.
Onboard a new product without printing a manual. The QR points to the latest documentation page.
Bus stops, café boards, in-window signs. Static QR + branded URL beats vanity short URLs for trust.
