QR codes on wedding invitations

Felice Caricati · November 12, 2026 · 2 minute read

In short

A QR code on the invitations opens the wedding website, where guests find the venues and times and can RSVP. Put it on the back or on a separate card, print it at least 2 centimetres wide and test it with several phones before printing every copy.

What it is for

The invitation stays something to keep, and the QR code adds what doesn’t fit on the card, from the map to the RSVP form. Guests scan it with their phone camera and don’t need to install anything.

Where to put it

On the front it risks stealing the attention from your names. The back of the invitation or a small card in the envelope works better, with one line saying what it opens.

For example: “Scan the code for the details of the day and to RSVP.”

How big to print it

Below 2 centimetres some phones struggle to read it. Leave a white margin around it and print it dark on a light background. A gold QR code on cream paper looks lovely, but often won’t scan.

Before sending it to print

Print a test copy and scan it with at least two different phones, in low light and from a distance. Check that it opens the right website and that the website is already live: if it isn’t published yet, whoever scans the code only sees “Our website will be online soon”.

Once the website is live, the dashboard has the QR code ready to download as SVG, the format print shops prefer. The code points to the website address, which stays the same even if you change texts or template.
