Wedding Invitation QR Code: What to Link, Where to Put It, and How to Test It

A QR code on a printed wedding invitation does one job: it takes a guest from a card that can never change to a page that can. Done well, it replaces the reply card, the details insert and the "what was the venue address again?" text. Done badly, it is a small black square that nobody scans and everybody asks you about.

This guide covers what to link, where to put the code, how big and how contrasty it needs to be, and how to test it before you pay for printing.

Why a QR code belongs on a printed invitation

Many couples now send a hybrid suite: one printed card plus a link to a digital page. The card sets the tone and ends up on the fridge. The page carries everything that changes or needs an action, such as the schedule, directions and the RSVP form.

The practical advantages are simple:

• You can fix a typo, update a start time or add parking details after the cards are already in the post.
• Replies arrive in one place instead of in the mail, in texts and in DMs.
• You can drop the separate reply card, details card and map insert, which lowers the print bill.

If you are not printing anything, you do not need a QR code at all. Send the link directly (our guide to digital wedding invitation etiquette covers how). The QR code exists for paper.

Decide what the code links to

Use one code with one destination. The best destination is the page where a guest can read the details and reply in the same visit, which is usually your digital invitation page. If you have not built one yet, see how to create a digital wedding invitation.

Good destinations:

• A digital invitation page with the RSVP form on it
• A wedding website with a clear RSVP section

Destinations to avoid:

• A PDF download, which is slow and hard to read on a small screen
• A form that asks guests to log in
• Several codes on one card, because guests will not know which to scan
• A link you plan to change later

A printed code can never be edited, so the address behind it has to stay live until after the wedding. Do not point it at a temporary or draft page.

Where to put it

• On the reply card. Replace the mail-back card with a line such as "Scan to reply by 1 March". This is the most useful placement.
• On the main invitation. Keep it small, in a bottom corner or on the back, so it does not compete with the wording.
• On the details card. A good home if you already have one for lodging and schedule.
• At the venue. On signs, table plans and the order of service, linking to the day's schedule or a map.

Whatever you choose, print the short web address as plain text next to the code. Some guests will not scan, and typing a short address is easy enough.

Size, contrast and materials

These are rules of thumb. The only real test is a printed proof.

• Size. About 2 cm (0.8 in) per side is a commonly used minimum for scanning at arm's length. Go bigger if your link is long, because longer addresses make denser codes.
• Clear border. Leave blank space around the code, roughly the width of four of its small squares. Printed text, borders or flowers touching the code can stop it from scanning.
• Contrast. Dark code on a light background. Pale gold or blush on cream looks lovely and scans badly. Light-on-dark (reversed) codes also fail on some phones.
• Materials. Foil, letterpress, vellum overlays, textured paper and dark stock can all make a code unreadable. Print it as flat ink on a smooth area.
• File type. Give your printer the vector (SVG) version so it stays sharp at any size. Use PNG for screens.

Make it and test it, step by step

1. Finish the page first. Publish your invitation page and confirm the link works.
2. Generate the code. Paste the link into the free QR code generator, check the contrast score, and download the SVG for print and the PNG for digital use. Nothing is uploaded when you do this.
3. Place it in your design with a clear border around it.
4. Print a proof at actual size on the actual paper you plan to order.
5. Scan it on at least three phones, including an older one, in dim light and from arm's length.
6. Test on mobile data, not just Wi-Fi, because that is what most guests will use.
7. Hand it to one older relative and watch whether they can scan it without help. If not, enlarge it or make the printed address more prominent.
8. Order the full print run only after all of that passes.

Common mistakes

• Linking to something temporary, then watching the page disappear before the wedding
• Printing the code too small to scan from a card on a table
• Using low-contrast brand colours that look great and scan badly
• Putting the code over a photo or pattern
• Forgetting the plain-text address for guests who do not scan
• Adding a second code for the registry, a third for the hotel and a fourth for the playlist. Put all of that on the page behind one code instead

What the page behind the code should contain

The code is only as useful as the page it opens. Guests should land on the date, time, venue and map, the dress code, and the RSVP form. If you are unsure what belongs there, our list of what to include on a wedding invitation works as a checklist, and the wedding RSVP guide for hosts explains how to collect and chase replies once they start coming in.

Frequently asked questions

Do I need a QR code if I already have a wedding website? Only if you are sending printed invitations. The code saves guests from typing a web address, and nothing more.

Will the QR code expire? A code generated directly from a web address contains the address itself, so it keeps working as long as the page does. Check that the page stays live until after the wedding.

Is a QR code too casual for a formal invitation? Not if it is tidy and placed on the reply card or the back of the invitation. Keep the front of the main card clean.

Should I add a logo or colours? Keep it simple. Every addition lowers scan reliability, so if you add anything, test the printed proof again.
