Create a QR code for Google reviews: free step-by-step guide (2026)
A QR code for Google reviews is the fastest way to turn on-site customers into reviewers: scan, tap the stars, done. This guide gets your review QR code created for free in under five minutes — and covers the print mistakes that ruin scan rates.
Which link does the QR code need?
Every review QR code starts with the direct link to your review dialog (format g.page/r/…/review). Our Google review link guide shows where to find it. Important: the link must open the star selector directly, not just your profile.
How do I create the QR code for free?
Right here: paste your review link or Place ID and get a static QR code as SVG or PNG. It is generated inside your browser, never expires and does not redirect through anyone else's server.
Place ID lookup, a comparison of the link formats and the print rules in detail are on the review link and QR code generator page.
Beware of “free” generators
What matters when printing?
- Quiet zone: four modules. The QR specification requires a clear margin four modules wide on all sides — a module is one of the small squares. Cropping that margin so the artwork fits better makes the code unreadable. It is the single most common printing mistake.
- Contrast: dark code on a light background. No white-on-colour, no gradients behind the code, no photo backdrop.
- Laminate matt, not gloss. Glossy film reflects ceiling lights exactly where the camera needs contrast.
- Error correction M is the usual standard and leaves headroom for scratches without shrinking the modules unnecessarily.
- Add a call to action: “Scan & review — takes 30 seconds” works better than a bare code, because the code alone does not say what happens next.
- Test before printing — iPhone and Android, from a realistic distance, in real lighting.
How big does the code need to be?
There is no official minimum size, but there is a reliable rule of thumb: scan distance divided by ten gives the edge length you need. It holds for clean codes with a proper quiet zone and is deliberately conservative — when in doubt print bigger, it costs nothing.
| Placement | Typical scan distance | Edge length by rule of thumb |
|---|---|---|
| Table or counter stand | 20–30 cm | 2–3 cm |
| Invoice, receipt, packaging | 25–30 cm | 2.5–3 cm |
| Reception desk, slightly further away | 50 cm | 5 cm |
| Shop window from outside | 1–1.5 m | 10–15 cm |
When the scan still fails
- Missing quiet zone — see above, the classic.
- Backlight or reflection: a code directly under a spot or behind glossy film loses contrast. Moving it is cheaper than reprinting.
- Too small for the distance: counter sizes fail reliably in a shop window.
- The code points at the profile, not the form: not a scanning problem but a link problem — and the most common reason people drop out even though the scan worked.
- Behind metal: irrelevant for QR, but worth knowing if you also use NFC — metal blocks it there.
Where to place it
- Checkout counter (the waiting moment while paying)
- Tables in restaurants and cafés
- Reception desk in practices, studios, salons
- Invoices, receipts, packaging
- Shop window (for passers-by after hours)
QR's limit — and when NFC is better
QR works everywhere but has friction: open camera, aim, tap the link. Modern smartphones support NFC — hold the phone to the sign and the link opens instantly, no camera needed. The highest conversion comes from combining both: NFC for the quick tap, QR as fallback. That's exactly how our review stands are built — pre-configured, retargetable anytime, with scan statistics. More in NFC stands for Google reviews.
Conclusion
A review QR code takes five minutes and costs nothing — what matters is the right link (straight into the review dialog), a static code, and placement with a call to action exactly where customers already wait.
FAQ
- How big does a QR code for Google reviews need to be?
- As a rule of thumb: scan distance divided by ten. For a stand on the counter that means an edge length of 2–3 cm; in a shop window viewed from the street, 10–15 cm. More important than size is the four-module quiet zone all round.
- Do QR codes expire?
- A static code contains the destination URL itself and never expires. Only codes from providers that insert their own short URL can expire — when that subscription ends, the printed code points nowhere.
- Does a QR code work through a shop window?
- Yes, glass is no obstacle for the camera. Watch out for reflections and make sure the code is large enough seen from outside. NFC, by contrast, does not work through glass.
- Can I put my logo on top of the QR code?
- Error correction usually tolerates a small logo in the centre; the quiet zone at the edge does not. If you want to combine them, put the logo next to the code rather than on it, and test with two devices before printing.
- Do I need NFC as well?
- You do not — a QR code reaches every device with a camera. NFC saves the camera step and is therefore faster at a counter. Our stands carry both so the question does not need answering.
