A QR code on a printed wedding invitation works when it is at least 2 x 2 cm (about 0.8 in), printed in dark flat ink on a light background, with clear space on every side, and tested on the real card before the full run. Put the fixed facts on paper (your names, the date, the venue) and let the code open a page that carries everything else: directions, timings, photos and replies.
If replies are your main reason for adding the code, our page on the RSVP QR code covers that side. This guide covers the printed card itself: what the code should open, where it sits, how big to print it, what to write next to it, and what to do about guests who never scan.
What the QR code on your invitation should open
Decide this first, because it changes the wording on the card and how long the code stays useful.
| The code opens | Good for | Watch out for |
|---|---|---|
| A wedding website only | Directions, schedule, dress code, travel | Replies still need a paper card or a second step |
| An RSVP form only | Collecting replies | Guests look elsewhere for the address and timings |
| One page with details and replies together | Both, from a single scan | Nothing extra, as long as the page stays live until the day |
Our pick is the third row. One scan should answer “where, when, what do I wear” and “let them know I’m coming” without a second link to find. That is how a wedding website built on Link Invitation works: the invitation, the event details and the reply form are the same page, so the code on your card opens all of it.
A code can also open a photo gallery or your love story if those live on the same page. Keep the card’s promise short, though. Tell guests the one or two things they will get from scanning.
Where to put the code on the card
The code is a tool, not the centerpiece. Place it where the eye lands last.
- On the main invitation: low on the card, under the date and venue lines, centered or tucked into a lower corner.
- On a details card: if your suite has an enclosure card for directions and accommodation, the code belongs there. It keeps the main card clean and puts the code next to the information it extends.
- On a reply card: only if the code replaces the paper reply. Printing both a code and a mail-back form on the same card asks the guest to choose, and some will do neither.
- On save the dates: a code that opens your page works here too, as long as that page is ready to show before the invitation goes out. More on that in our guide to save the dates.
Keep the code away from folds and the center crease of a folded card, out from under wax seals, ribbon, belly bands and vellum wraps, and well inside the trim line so the printer’s cutting tolerance does not shave off its white border.
Size, clear space and contrast
Three specs decide whether a printed code scans.
Size. Print the code at least 2 x 2 cm (0.79 in). That holds a typical web address of up to 72 characters and reads from about 20 cm away. For other distances, use a 10:1 rule: the reading distance is about ten times the code’s width. A card held in the hand sits comfortably inside that range. A welcome sign read from 1.5 meters needs a code about 15 cm wide by the same ratio.
Clear space. Leave a blank margin four modules wide on every side, the standard set by the QR code’s inventor. A module is one of the small squares in the pattern. Do not crop that border in your design file, and do not let text or illustration creep into it.
Contrast and ink. Use dark squares on a light background, with black on white the safest combination. Avoid red or orange as the dark color, and never invert the code (light squares on a dark background), because some scanners will not read it. Print the code in flat ink: a code in regular or raised foil will not scan reliably, so keep the foil for your names and borders.
One more factor sits inside the code: the longer the web address it holds, the denser the pattern and the harder it is to read. If your invitation link can be renamed to something short, do it before you generate the code.
The pre-print QR checklist
Run this before you send the final file to the printer, and again on the printed proof.
| Check | Target | Why |
|---|---|---|
| Size | At least 2 x 2 cm (0.79 in); larger if the card is dark, textured or busy | Reads at about 20 cm with a typical web address |
| Scanning distance | Code width about one tenth of the reading distance | The 10:1 rule for anything read from further away |
| Quiet zone | Four modules of blank space on each side | Phones use the margin to find the code’s edges |
| Contrast | Dark code on a light background; black on white is the safest | Phones read the difference between dark and light, not the color |
| Colors to avoid | Red or orange as the dark color; inverted (light on dark) codes | Some scanners cannot read them |
| Ink | Flat ink on the code; keep foil, glitter and metallics off it | Shiny finishes reflect light and break the read |
| Address length | Shortest version of your link before the code is made | Fewer characters, simpler pattern |
| Placement | Off folds, under no seals or ribbon, inside the trim line | Physical damage to the pattern or its border |
| Page status | Invitation published and link name final before printing | The code holds the exact address, so keep the name fixed once cards are printed |
| Test devices | Printed proof, real paper stock, ordinary indoor light, at least two phones including an older one | A screen preview hides paper texture, glare and print spread |
| Fallback | Short web address and a name with a phone number printed near the code | For guests who do not scan |
If the proof hesitates on any phone, make the code bigger before changing anything else. Size is the setting that buys the most reliability.
What to write next to the code
“Scan me” tells guests nothing. The line beside the code should say what they get and what to do, in one or two short sentences.
Some lines to adapt:
- Scan for directions, the day’s schedule and to reply by June 14.
- Point your phone camera at the square for maps, timings and your reply.
- Everything else you need is here: venue directions, hotel details and our reply form.
- Scan to reply, or call [name] at [number] and they will reply for you.
Print the reply-by date in words on the card, not only behind the code. A guest who never scans should still know the date. An iPhone scans QR codes straight from the Camera app or Control Center, so “open your phone camera” is a fair instruction for iPhone guests, with no app to download.
Guests who won’t scan
Some guests will not scan, whether from habit, an older phone or simply preferring paper. Plan for them on the card rather than chasing them later.
- Print a short web address under the code, so the page can be typed in.
- Name a person and a phone number. A parent, sibling or friend who can reply on a guest’s behalf turns a missing reply into a two-minute call.
- Keep the essentials in print. Date, time, venue name and address belong on the card in full. The code adds to the card, it does not replace it.
- Consider a short paper reply run. A handful of mail-back reply cards for the guests you know prefer them costs little and removes the guesswork.
If plans change after the cards are printed
This is where the code earns its place. Ink is fixed; the page behind the code does not have to be.
| You can still change | Keep fixed once cards are printed |
|---|---|
| Ceremony and reception times | The link name or web address the code holds |
| Venue details, maps and directions | Whether the page is published and live |
| Schedule, dress code, hotel notes, photos | The printed date, if it moved (send a notice, the card still shows the old one) |
| The reply-by date on the page |
Edit the page once and everyone sees the latest version, including guests who scan a printed card. Settle your link name before you print. The code holds that exact address, so treat the name as fixed once the cards are ordered.
One thing to know about printed codes in general: if you print one card design for everyone, every card carries the same code, so the page cannot tell who scanned it. Plan to check replies that arrive that way against your guest list.
Design tips that keep the code from spoiling the card
- Frame it on purpose. A thin keyline, a small label above it or a matching corner motif makes the code look placed rather than pasted.
- Match the color carefully. A deep navy, forest green or charcoal from your palette can replace black if the contrast stays high. Test it.
- Keep it small but honest. Size it to the checklist minimum and resist shrinking it for looks.
- Be cautious with logos and styled dots. QR codes have built-in error correction that lets a partly damaged code still read. A monogram in the middle or restyled dots uses up some of that margin before the card ever gets a smudge. Proof them on paper before you commit.
- Give it room. The quiet zone is part of the design. Plan the layout around it.
A QR code that opens a page you can keep editing
If you want the code on your card to open a page that does the rest of the work, Link Invitation gives you one. Your invitation comes with a QR code you send to your own printer (we do not print cards), and it opens your invitation page: event details, maps, a countdown, add to calendar, a photo gallery, and the reply form. You can also build a printable QR sign for the welcome table.
For the guests who are not getting paper, each one gets a personal invitation link with their name on it, sent from your own WhatsApp, one tap per guest, as described in WhatsApp delivery. You can see who opened their link and when, and follow replies on a live RSVP dashboard, where replies from a scanned card wait for your review before they count.
Pricing is a one-time payment per invitation, with no subscription and unlimited guests: Essential is $29 and you build it yourself; Excellence is $99 and it is designed for you. Essential is free to build and preview before you pay, and you can keep editing after you publish.
Frequently asked questions
Is it tacky to put a QR code on a wedding invitation?
Not when it is placed with care. A small code low on the card or on a details card reads as a practical extra, much like printing a wedding website address. It looks out of place when it is the biggest thing on the card or replaces the date and venue. Keep the essentials in print, size the code modestly and give it a clear label.
Should I still include a paper RSVP card?
That depends on your guest list. If nearly everyone uses a smartphone, a code that opens your reply form can replace the paper reply card. If you have guests who prefer mail, print a small run of reply cards just for them, and keep a name and phone number on the invitation as a third way to answer.
Can I use the same QR code on save the dates and invitations?
Yes, if the code opens a page that will hold the full details later. Guests who scan a save the date see what is ready now, and the same printed code shows the updated page once you add the schedule and reply form. Make sure the page is published before the save the dates are mailed.
Do QR codes on wedding invitations stop working?
A code that holds your page’s address directly keeps working as long as that address stays live. It stops when the page is taken down or the address changes. Some generator services route codes through their own short links, which then depend on that service staying active, so read the terms before you use one for printed cards.
