QR code size guide
- 1
Rule of thumb: 1:10 ratio
Print size = scan distance ÷ 10. A 2 cm QR reads at 20 cm (business card distance); a 10 cm QR reads at 1 m (poster); a 30 cm QR reads at 3 m (window display).

Account for module density
QRs encoding longer URLs have more modules (smaller squares per cm). A v1 QR (21×21 modules) at 2 cm is fine; a v10 QR (57×57) at the same size scans unreliably.

Minimum scannable size: 2 cm
Most phone cameras struggle below 2 cm on glossy paper. Matte paper improves contrast; reflective stickers usually need 3 cm minimum.

Business cards & flyers
2–3 cm is standard. Use error correction level Q (25%) so logo overlays remain scan-safe.

Posters, billboards, outdoor
For a poster viewed at 1 m, use 10 cm. For a billboard viewed at 10 m, use 1 m. Add a 4-module quiet zone of white around the code.
Frequently asked questions
What is QRCode Suite?
QRCode Suite is a standalone QR code platform: create a free account and generate branded, dynamic QR codes in the browser — no WordPress required. Connectors bring the same codes to WordPress and WooCommerce, where orders can be attributed to specific QR codes.
Does QRCode Suite work without WordPress?
Yes. QRCode Suite is a standalone SaaS — sign up, create QR codes, and track scans entirely on qrcode-suite.com. The WordPress plugin is an optional connector that brings your codes into wp-admin and adds WooCommerce order attribution.
Does QRCode Suite require a separate subscription?
The Free plan is available at no cost — no credit card required. Paid plans (Pro €9, Business €29, Agency €79 per month) unlock unlimited codes, redirect rules, and more. There is no separate per-scan fee.
What QR code types does QRCode Suite support?
QRCode Suite supports 22 QR code types: Static URL, Dynamic URL, Plain Text, Phone, Email, Location, Link Hub, SMS, WhatsApp, Wi-Fi, vCard, Social profile, PDF, File download, App download, Coupon, Calendar event, Lead capture form, Review collection, Wholesale inquiry, Loyalty reward, and Custom payload.
Can I change the destination of a QR code after printing it?
Yes. Dynamic QR codes use a short redirect URL. You can update the destination from your dashboard at any time without generating or reprinting the code.
Is QRCode Suite GDPR-compliant?
QRCode Suite is built with GDPR in mind: raw IP addresses are never stored — visitors are counted with keyed hashes — bot traffic is filtered automatically, and scan events are purged once your plan retention window elapses. Consult your legal team for your specific obligations.
