How to Make a QR Code for a Wedding Invitation

A paper invitation has little room for a map, gift details, an RSVP and photos. That is why many couples add one QR code that opens a mobile invitation page. A pretty code is nice, but what matters first is that every guest can open it without trouble. Here is the process from preparation to print.

1. Decide the link first

A QR code is only a container for an address. If you make it before the destination is settled, you may have to reprint everything later.

• Pick one destination: a mobile invitation, an event info page or an RSVP form. Instead of cramming several links into one code, gather them on a single page.
• A page that only opens when you are logged in will not open for guests. Try it in a private window or on someone else's phone.
• After printing, the address inside the code cannot change. You can edit the page content, but choose an address that will stay alive.
• Do not publish a guest list or phone numbers on a public page.

2. Choose a shape and colors

Heart and couple shapes fit an invitation well. Mandu QR offers built-in shapes such as a heart and a bride-and-groom silhouette, plus presets that go with them. The following habits keep it pretty and readable.

1. Use dark modules (deep rose, burgundy, navy) on a light background. Pale pink dots look even weaker once printed.
2. Do not hide the three large corner squares, the finder patterns.
3. Leave generous empty space around the code so floral borders or ornaments from the card design stay away from it.
4. A center logo or monogram can hurt scanning. Keep it small and test it.

3. Add wording and a frame

A bare code does not say what it is. Add one short line. The frame and caption feature in Mandu QR lets you place text directly below the code.

• Examples: "Open the invitation", "Directions and RSVP".
• For guests who are not used to scanning, also print a short address or a contact method they can type.
• A long caption shrinks the code, so keep it brief.

4. Print size

Invitations are small, so the QR tends to end up small too. As a rule of thumb, treat about 2.5 cm wide as the lower limit for close-range scanning and aim for 3 cm or more. Make it larger if you use a shape or a logo. The true minimum depends on how long the address is and on print quality, so a test print is the only reliable answer. Keep an SVG, which stays sharp at any size, and hand the printer an SVG or a large PNG.

5. Test checklist

1. The downloaded file opens the invitation page right away.
2. A test print scans on both iPhone and Android.
3. The page opens while logged out, or on another person's phone.
4. It loads at a reasonable speed on mobile data.
5. The address will stay online for months after the wedding.
6. Ask an older relative to scan it once. It is the most honest test.

6. If you send a mobile invitation

For invitations shared through a messenger or text, a QR code is often unnecessary because guests can simply tap the link. It becomes useful when the same invitation appears on a venue sign or a thank-you card. In that case save a PNG and keep using the original downloaded file instead of repeated screenshots. When someone scans a code from a screen, raise the screen brightness and hold the screen flat.

• Sign at the venue entrance: people stand farther away, so print it 10 cm or larger.
• Thank-you card: link a photo album together with your thanks.
• After the event, close the RSVP page or turn it into a photo-sharing page so an old code does not lead somewhere unexpected.

Mandu QR is free, needs no sign-up, and does all of this in your browser. The address you enter is not sent to a server.
