+ The right QR code size depends on one thing: how far away will the scanner be? + This guide gives you exact minimum dimensions for every print surface. +
+Quick Rule of Thumb
++ QR code width = scan distance ÷ 10. Example: scanning from 30 cm → minimum 3 cm wide. +
+| Surface | +Scan Distance | +Minimum Size | +Recommended | +Format | +
|---|---|---|---|---|
| {row.surface} | +{row.scanDistance} | +{row.minSize} | +{row.recommended} | +{row.format} | +
+ Sizes are for QR codes with standard black-on-white contrast at error correction level Q or H. Reduce minimum sizes by 20% only in ideal lighting conditions. +
++ Use PNG at 300 DPI minimum for business cards, flyers, and small posters. Export at 10× your target print size in pixels (e.g. 3 cm at 300 DPI = 354 px). +
++ SVG is a vector format — it scales to any size without quality loss. Use SVG for all A2+ posters, banners, and billboards. QR Master exports SVG directly from the generator. +
++ Use Level Q (25% recovery) or Level H (30% recovery) for print — especially if you add a logo. Higher error correction means more modules and a slightly larger minimum size. +

++ Common questions about Google Review QR codes. +
+ +A static QR code encodes data permanently — you cannot change it after printing. A dynamic QR code uses a short redirect URL so you can update the destination at any time without reprinting. Dynamic codes cost more but are essential for print campaigns where links change.

A dynamic QR code routes through a redirect you control, so you can update the destination at any time without reprinting. Dynamic codes are essential for any campaign where URLs change.
+A static QR code encodes your data — a URL, contact, WiFi password, or plain text — directly into the QR pattern. Once generated and printed, that data is permanent. You cannot change it.
+Static codes work fine for:
+The problem starts when you use static QR codes for business campaigns where URLs change — menus get updated, promo pages expire, link structures migrate. Every change forces a full reprint.
+ +A dynamic QR code encodes a short redirect URL (e.g., qrmaster.net/r/abc123) instead of your final destination. You control where that redirect points in a dashboard. Change the destination, and the printed code automatically sends scanners to the new URL — no reprint needed.
Dynamic codes also enable:
+| Feature | +Static QR Code | +Dynamic QR Code | +
|---|---|---|
| Edit destination after print | +No | +Yes | +
| Scan analytics | +No | +Yes | +
| Reprint needed when URL changes | +Yes | +No | +
| Cost after printing | +€0 (but reprints add up) | +Subscription fee | +
| Works offline (WiFi, vCard) | +Yes | +URL-based only | +
| Best for | +One-time / permanent use | +Campaigns, print, marketing | +
Here is where the math matters. Many businesses default to static QR codes because they are free to generate. But when the linked URL changes — which happens more often than expected — the cost of reprinting is significant.
+ +A restaurant prints 200 table tent cards with a static QR code linking to their PDF menu. The menu changes quarterly (seasonal updates). Each reprint batch costs €60 in printing.
+A retailer places 500 shelf talkers with a static QR linking to a seasonal promotion page. The promotion runs 6 times per year.

+Dynamic is the right choice when:
+Get started with a dynamic QR code generator to create codes you can update after printing. Pair it with QR code tracking to see exactly who scans and from where.
+ +The choice between static and dynamic QR codes comes down to one question: will the destination ever change? If yes, use dynamic — the subscription cost is almost always lower than the cost of reprinting. If no, static is free and perfectly adequate.
