How to prepare a QR code for a trade show booth

A QR code at your booth can send visitors to a product page, contact form, demo signup, or digital brochure. But a code that scans on your laptop screen may fail when printed small, placed under bright lights, or viewed from a few feet away.

Set up the destination first, then check the code at its actual printed size and from the distance visitors will use it. The QR Code Generator can make a code for a link and lets you customize colors and add a logo.

Prepare the QR code

1. Open the QR Code Generator and choose the link or URL option. Enter the complete destination, including https://, and check the address carefully for typos.
2. Use a page that works well on a phone. Make sure visitors can reach the important information quickly, and that the page does not require a login they may not have. If the event venue has unreliable internet, consider whether the page will still be useful on a mobile connection.
3. Choose a dark foreground on a light background. You can use brand colors, but keep the code easy to distinguish from its background. If you add a logo, keep it modest in size so it does not cover too much of the pattern.
4. Save or export the code using the largest or highest-quality option available. Avoid taking a screenshot of a small preview, since enlarging it for print can make the edges blurry.

A URL QR code contains the address you enter. If that address changes after printing, the code will still point to the old one. A stable redirect link that your team can update later can help avoid reprinting, if you have one.

Choose the right print size and design

Visitors will scan from close range

For a sign on a counter or a handout visitors can pick up, a code around 2 to 3 inches wide is a practical starting point. Print a sample at the intended size and try scanning it with more than one phone. If the code is densely patterned because the URL is long, give it more space or use a shorter, stable address.

Visitors will scan from farther away

A code on a standing sign should be larger than one on a brochure. As a rough starting point, allow about 1 inch of code width for every 10 inches of scanning distance, then test the result in the actual booth layout. A visitor should not have to approach the sign or hold a phone at an awkward angle to scan.

You want to include a logo or brand colors

Keep enough contrast between the dark modules and light background. Avoid putting a light code on a dark background unless you have tested it thoroughly, and do not place decorative artwork behind the code. A logo can make the design feel branded, but it also covers part of the pattern. Read how to choose QR code colors that still scan before using a less familiar color combination.

You are choosing error correction

Error correction helps a QR code remain readable if part of it is damaged or obscured, but higher correction can make the pattern denser. If your generator offers this setting, select it with the design in mind and test the printed result, especially if you add a logo. See how to choose a QR code error correction level for the tradeoffs.

Fix common print problems

1. Leave a clear border. QR codes need an empty margin around the pattern, often called a quiet zone. Do not let a border, text, or nearby graphic touch the code. Keep a clear margin on all four sides in the printed layout.
2. Increase the size before changing the design. If phones struggle to focus on the print, enlarge the code and test again. Shrinking the code to fit a busy layout can leave too few clear details for a camera to read.
3. Use stronger contrast. If a code scans inconsistently, switch to a dark code on a plain light background. Avoid low-contrast brand shades, shiny surfaces, and patterns that compete with the QR modules.
4. Remove or reduce the logo. If the code fails after you add a logo, make the logo smaller or remove it. A clean code is more important than a logo in the center.
5. Print a fresh proof. Check the final PDF or print file at its actual size. Do not judge only from a zoomed-in screen preview, and avoid stretching the code out of its square shape.

Test it in the booth conditions

Print one proof using the same material and size planned for the booth. Place it at the intended height and angle, then scan from where a visitor is likely to stand. Test with at least two phones if possible, and check that each opens the correct page rather than only confirming that the camera recognizes a code.

Try the proof under the venue's lighting if you can. Glare from a glossy sign, reflections from a protective sleeve, or a strong light aimed at the code can make scanning unreliable. Matte printing and a slight change in angle may help. Also check that the code is not partly hidden by a stand, a brochure, or a queue of people.

If you are comparing a static code with a service that lets you change its destination later, make sure you understand whether the service adds tracking or requires a subscription. This guide to static and dynamic QR codes explains the difference.

Keep a copy of the final code and its destination with your event files, so the team can verify the link or reprint the sign if needed.
