Wedding photo QR codes, explained
A wedding photo QR code is a printed square that opens a photo page when a guest points a phone camera at it. There is nothing to install. Size it at about a tenth of the distance you want it scanned from, print it dark on light, and put it where people already stand still.

What happens when a guest scans it
Every phone sold in the last several years reads QR codes from the normal camera app — no separate scanner. The guest points, a notification appears, they tap it, and a web page opens.
What that page does depends entirely on what you pointed the code at, and this is the part most guides skip:
- A camera page. The browser asks permission to use the camera and the guest shoots from the page itself. Photos land with you as they're taken. This is what event camera services use.
- A form for adding files. The guest picks photos already on their phone. Works after the fact, but re-creates the every-guest-must-remember problem.
- A shared album link. Same as sending the link any other way — the code just saves typing.
- A gallery to look at. One-way; useful for showing the developed photos afterwards, not for collecting.
Only the first one collects at the moment of the photo. If you're choosing a service, that's the question to ask.
How big should a wedding QR code be?
The working rule is a 10:1 ratio: a code scans reliably from about ten times its own width. Everything follows from that.
| Where it goes | Scanned from | Print at least |
|---|---|---|
| Table card, order of service, menu | ~30 cm / 12 in | 3 cm / 1.2 in |
| Bar sign, easel card at eye level | ~1 m / 3 ft | 10 cm / 4 in |
| Welcome board across a room | ~3 m / 10 ft | 30 cm / 12 in |
Round up. A code that's slightly too big costs nothing; one that's slightly too small fails silently — the guest points, nothing happens, and they put their phone away and don't try again.
Where to put it
Codes get used where people are standing still with a free hand. In practice:
- One per table, in the table-number holder — the highest-return placement by a distance
- The bar, at eye level, where people queue with nothing to do
- By the toilets. Unromantic, and consistently one of the most scanned spots at any event
- The back of the order of service, so it's in every hand during a quiet twenty minutes
- Not the entrance. People arrive holding coats and looking for their seat, and scan nothing for the first ten minutes
What to write next to it
The code needs a sentence, or people don't know what it does and won't risk it. Short, plain, and it should say what happens:
It states the action, removes the install objection, and sets the expectation about when they'll see anything. Avoid "scan me" on its own: it tells a guest to do something without telling them why, and most won't.
Five things that stop a code working on the day
- The venue has no signalThe code scans, the page won't load. Check reception in the actual room, not the car park, and ask about guest wifi — then put the wifi name and password on the same card.
- It's printed light on darkInverted codes look better on a dark palette and scan far less reliably. Dark code, light background, every time.
- It's behind glossy acrylic under a spotlightGlare wipes out the contrast the camera needs. Matte finish, or angle it away from the lights.
- It's on a curved surfaceBottles, candle holders and anything cylindrical distort the pattern past the point the decoder can correct for.
- Nobody told anyoneThe most common failure and the least technical. One line during the speeches beats every printed card in the room.
Test it before the day
Print one at final size, on the final paper stock, and scan it with the oldest phone you can borrow, at the distance and under the light it will actually live in. That five-minute test catches four of the five failures above.
Common questions
Do guests need an app to use a wedding QR code?
No. Modern phone cameras read QR codes natively, and a well-built photo page runs in the browser. If a service asks your guests to install something before they can shoot, it has given up the main advantage of using a code at all.
How big should a wedding QR code be?
About a tenth of the distance you want it read from. Roughly 3 cm for a table card read at arm's length, 10 cm for a bar sign at a metre, 30 cm for a welcome board across a room. Round up, and keep the white border.
What if the venue has no phone signal?
Ask about guest wifi and print the network name and password on the same card as the code. If there is neither, in-the-moment capture won't work reliably and you're better off with physical cameras.
Can one QR code be scanned by everyone?
Yes. A single code can be printed as many times as you like and scanned by every guest — you don't need one per person. Copy the same artwork onto every table card.
Do QR codes expire?
The code itself doesn't; the page it points at can. Avoid free link shorteners for anything printed, because the shortener is a second thing that has to still exist on the day.
