How to use QR codes on flyers and posters

Decide what one thing the QR should do

A flyer or poster has the attention of someone walking past. You have two seconds to make them want to scan, then five seconds for the scan to do something useful. Pick one job for the QR—not three.

Common single-job picks for small businesses:

• Open a booking page – salons, dentists, fitness classes, repair shops.
• Open a menu – restaurants, food trucks, bakeries.
• Open an event RSVP – workshops, openings, pop-ups.
• Open a special offer page – seasonal promos and grand openings.
• Save a contact card – freelancers, real-estate agents, plumbers.
• Open directions – first-time visitors to hard-to-find storefronts.

Each one of those uses a different LocalQRTools generator: Link QR, Menu QR, Event / RSVP QR, Contact QR, or Location QR.

Where on the flyer should the QR go?

The bottom-right corner is the safest spot. Eyes scan top-to-bottom, the QR feels like a "next step," and it stays out of the way of the headline.

Other reliable placements:

• Bottom-center – good when you want the QR to feel like a clear call-to-action.
• Right column on a vertical poster – works if you have a body-copy block on the left.
• Top-right – fine for posters viewed from a distance where people read the headline first.

Avoid placing the QR over a busy background image, gradient, or photograph. The contrast will be inconsistent and scans will struggle.

What to write next to the QR

One short sentence is enough. Tell people exactly what happens after they scan. Skip "scan me" by itself—it's vague and doesn't sell the action.

• "Scan to book"
• "Scan for tonight's menu"
• "Scan for class times"
• "Scan to RSVP"
• "Scan for directions"

If your audience skews older, add a one-line backup like "or visit example.com/menu" so people who don't scan can still find the page.

How big should the QR be?

The right size depends on how far away people will read the flyer:

• A5 / quarter-page handouts – at least 2.5 cm (1 in) per side.
• A4 / letter flyers – at least 3 cm (1.2 in) per side.
• Posters viewed at 1-2 m (3-6 ft) – at least 5 cm (2 in) per side.
• Posters viewed at 3-5 m (10-16 ft) – at least 10 cm (4 in) per side.
• Bus stops, large windows – 15-25 cm (6-10 in) per side.

Test by printing a single proof, mounting it where the real one will hang, and trying to scan from a normal viewing distance. If it takes more than two seconds to focus, increase the size.

Margins and contrast

• Leave at least the equivalent of four QR modules of white space on every side of the code—this is called the "quiet zone." Without it, scans start failing.
• Use dark on light, not light on dark. Most phone scanners assume dark modules on a light background. Inverted QRs sometimes work, but you lose reliability for no real benefit.
• Don't print the QR over a photograph. If you must, add a solid white panel behind the QR.
• Avoid colored QRs unless contrast stays high. Black on white is the most reliable; black on yellow or pale blue can also work; anything close in luminance won't.

Print quality matters more than design

The single most common reason flyer QRs fail is low resolution. If you export a 100-pixel QR and stretch it to print at 5 cm, the modules blur and scans break. Always export the QR at print resolution—on LocalQRTools, the downloaded PNG is high-res enough for most flyer and poster sizes up to A3 / tabloid.

For larger posters, generate the styled PNG and upload it directly to your printer's design tool without rescaling.

Posters specifically: longevity

Posters live outside or in busy spaces for weeks or months. Two practical adjustments:

• Use a Link QR pointing to a permanent page on your site, not a campaign-specific URL that might expire.
• If you want to update the destination later, point the QR to a redirect URL on your own domain (like yourbusiness.com/poster) and change what that redirects to. The QR stays the same.

Common mistakes

• QR with no label—people don't know what they'll get.
• QR placed too close to the edge of the page (paper-cut margins shave off the quiet zone).
• Multiple QRs on the same flyer—forces a choice and reduces the chance of any single scan.
• QR pointing to a page that doesn't open well on mobile. Always test the destination on a phone, not a laptop.
• QR pointing to a homepage when the flyer was about a specific offer. Land on the relevant page.
