How to Make a QR Code for an Event (RSVPs, Tickets, Schedules and Check-In)

Events are one of the best places to use QR codes. Guests already have their phones out, and a code on an invitation, poster, badge or table can take them straight to the RSVP form, the schedule, the venue map or the WiFi. The QR code itself takes a minute to make. What decides whether it helps is what the code opens and where you put it.

This guide walks through both, from the first invitation to the feedback form after the event. For the basics of turning any link into a code, see how to make a QR code for a link.

Step 1: Decide what each code should open

A QR code can only hold one thing. Before you make it, decide what a guest needs at that exact moment:

If you need guests to find several things, the simplest option is one event page with everything on it: date, time, address, schedule, RSVP button and FAQs. Then one code on the invitation can lead to all of it.

Step 2: Use a short, stable link

The link inside a static QR code cannot be changed after you print it. So choose a link that will keep working:

• Use a page you control where possible, such as a page on your own website. If the time or room changes, you update the page and the printed code still works.
• Avoid links that expire, such as temporary file-sharing links or one-time invite links.
• Do not put personal ticket links on public posters. A personal ticket or check-in link belongs to one guest. Public signs should point to a general page.
• Keep it short. Shorter links create simpler codes that scan more easily, especially when printed small.

If your RSVP form is a Google Form, our guide to QR codes for Google Forms covers the right link and sharing settings. If the code should open a printable schedule, see QR codes for a PDF.

Step 3: Generate the QR code

1. Open the QR Studio generator and choose the URL tab.
2. Paste your event link. Remove any extra spaces before or after it.
3. Keep dark modules on a light background for the most reliable scans. Event colors are fine, as long as the contrast stays strong.
4. If you add a logo, keep it small and leave the three corner squares clear.
5. Scan the preview with your phone camera and confirm the right page opens.
6. Download the PNG and place it in your invitation, poster or slide.

QR Studio creates static codes in your browser, so the link is stored in the pattern itself, with no account or redirect service in between. Static codes do not expire; they keep working for as long as the link inside them does.

Codes for other event needs

Venue WiFi

A WiFi code lets guests join the network without typing a long password. Use the WiFi tab, enter the network name and password exactly as they are, and put the code on table cards or near the entrance. Our WiFi QR code guide and the post on making a WiFi QR code explain the settings. Use a guest network rather than your private one.

Speaker and staff badges

A vCard code on a badge lets people save a speaker's or organizer's contact details in one scan. Keep the card short (name, organization, email, website) so the code stays easy to scan. See the vCard QR code guide.

Venue location

For directional signs or invitations, link to a map pin for the venue entrance or parking. Our guide to QR codes for a location shows how to get a link that opens the right spot.

Short information without internet

The Text tab stores a short message inside the code itself, such as "Doors open 6 pm. Workshop in Room 204." Phones can show it even without a data connection. The downside is that you cannot update it after printing, so use it only for details that will not change.

Can a QR code add the event to a calendar?

Some generators offer a special calendar-event format, but support for it varies between phones and scanner apps. QR Studio does not have a calendar tab. A more reliable approach is to link to an event page with an "Add to calendar" button, or to a calendar invite file hosted on your own site.

Size and placement

A widely used guideline is to make the code roughly one tenth of the scanning distance in width, then test it. Some examples:

For example, a sign people will scan from about 2 meters away should have a code about 20 cm wide. The QR code size guide and QR code size for print have more detail.

A few placement tips:

• Add a call to action such as "Scan to RSVP", "Scan for the schedule" or "Scan for WiFi".
• Print a short URL under the code so people who cannot scan can type it.
• Put codes at eye level and away from glare, and keep them out of crowded doorways where people cannot stop.
• On slides, make the code large and leave it on screen long enough for the back row to scan.

Track scans with UTM tags

Static codes do not count scans by themselves. If your event page uses an analytics tool, you can add UTM parameters to the link so visits from each printed code show up separately. For example:

https://example.com/spring-fair?utm_source=poster&utm_medium=qr&utm_campaign=spring-fair

Make one code with utm_source=poster and another with utm_source=flyer, and you can compare which placement brought more visits. The extra text makes the code denser, so print tagged codes a little larger.

Test before you print

1. Scan every code with at least two phones, ideally one iPhone and one Android phone.
2. Test while signed out of any accounts to see what a guest will see.
3. Submit a test RSVP and check that it arrives. Delete the test entry afterwards.
4. Print one proof at the real size and scan it from the real distance.
5. On event day, scan the codes once more after they are put up.

If a code will not scan, work through QR code not scanning.

Frequently asked questions

Can I make a QR code for an event for free?

Yes. Paste your event page or RSVP link into the URL tab in QR Studio, check the preview and download the PNG. There is no signup.

Can I change the event details after printing the QR code?

Not inside a static code. But if the code points to a page you control, you can update that page and the printed code will show the new details.

How big should a QR code be on an event poster?

A common rule is about one tenth of the scanning distance. A poster scanned from 1–2 meters needs a code about 10–20 cm wide.

Do event QR codes expire?

Static QR codes from QR Studio do not expire. A code stops working only if the link inside it stops working.

Can one QR code do everything for my event?

One code can open one link, so point it at an event page that lists everything. Use separate codes for WiFi or contact cards.
