QR Codes on Wedding Invitations: How to Use Them (and Get Them Right)
Where to put a QR code on your wedding invitation, how big to print it, website vs personal RSVP codes, testing before you print, and signs for the day.
In short
A small QR code on a printed invitation means guests can reply from their phone in seconds, and you skip the RSVP card, the extra stamp and the trip to the letterbox. Done well, it's barely noticeable. Done badly, it either won't scan or it takes guests somewhere they can't do anything useful.

Two kinds of QR code
A website QR code takes everyone to the same place: your wedding website. It's perfect for save the dates, welcome signs and the back of the invitation. Guests can still RSVP by searching their name.
A personal RSVP QR code is different for every household. Scanning it opens their invitation, already knowing who they are and which events they're invited to. Their reply goes straight into your guest list with no typing of names. It's the best option for printed invitations, but it means each envelope gets its own card, so keep track of which card goes in which envelope.
On Online Wedding Invitation, the Share & print page gives you both: a website QR to download, and a sheet of printable RSVP cards with a code for every household.
How big should it be?
- At least 2 cm square on an invitation; 2.5 cm is safer.
- Bigger for signs: around 8–10 cm on an A4 sign that people will scan from a step or two away.
- Leave a clear margin around it (the "quiet zone"). Don't crowd it with borders or florals.
Colours and contrast
Dark code on a light background, always. Deep ink, charcoal or navy on white or cream scans perfectly. Gold foil, pale blush on white, or a light code on dark card can fail on older phones. Our codes use your theme's text colour, which keeps them readable while matching the rest of the stationery.
Test before you print the lot
- Print one proof at the real size on the real paper.
- Scan it with an iPhone and an Android phone, ideally an older one.
- Check it opens the right page, and for personal codes, the right household.
- Then print the run.
Where it goes on the invitation
Most couples put it on the RSVP card or the back of the invitation, with a short line beside it (more lines to copy in our invitation wording guide):
Scan to RSVP by 1 February
Everything you need to know, and your RSVP, is here
Keep a short web address under it too (your website link) for anyone whose camera won't cooperate.
QR codes on the day
- Welcome sign: "Scan for the timeline and the menu."
- Tables: a small card linking to your website, where guests can find the photo gallery afterwards.
- Shuttle or parking signs: a code to a map, handy at regional venues where phone signal is patchy (load the page before you lose reception).
Posting printed invitations?
Australia Post now delivers regular letters every second business day in most areas, so allow more time than you used to (our invitation timeline). A QR code means guests can reply the minute the envelope arrives instead of posting something back.
Each code opens that household's own reply page. More on our online wedding RSVP.
Quick questions
How big should a QR code be on a wedding invitation?
At least 2 cm square, and 2.5 cm is safer, with a clear margin around it. On an A4 sign, make it about 8 to 10 cm.
What colour should the QR code be?
Dark on light: deep ink, charcoal or navy on white or cream. Gold foil or a pale code can fail on older phones.
What's the difference between a website QR code and an RSVP QR code?
A website code takes everyone to the same page. A personal RSVP code is different for each household and opens their own invitation, so replies need no typing.
