A QR code can connect a printed item to a website, menu, map, contact form, catalogue or campaign page. Scanning depends on the entire printed result—not just whether the code works on a computer screen. The code needs sufficient size, a clear quiet zone, strong contrast, suitable material and a destination that is ready for mobile visitors.

Start with the destination

Core print requirements

• Keep the code square and do not stretch it.
• Maintain a clear quiet zone on all four sides.
• Use strong contrast between the dark modules and light background.
• Avoid busy photos, metallic effects or transparent areas behind the code.
• Do not place the code across folds, perforations, seams, curves or trimming risk.
• Use a vector code where possible, or a raster file with adequate resolution at final size.
• Test from the exported print-ready PDF and from a physical sample.

How large should a printed QR code be?

There is no universal size because scanning depends on data density, print quality, viewing distance, surface and phone camera. A simple code on a close-view business card can be smaller than a code intended for a wall sign. Longer encoded data produces a denser pattern and may require more printed area.

QR codes on business cards

A business card is handled at close range, but space is limited. Keep the code away from trim and rounded corners, and avoid surrounding it with dense contact details. Pair it with a short instruction such as “View portfolio” or “Save contact.”

When ordering standard business cards, consider paper, lamination and finishing together. Strong gloss, reflective effects or a fold across the code can make scanning less reliable under some lighting. Test the finished specification rather than only an office-paper proof.

QR codes on flyers and brochures

Flyers provide more space for context. Use the code near the relevant offer or call to action, not automatically in the smallest footer area. On folded brochures, keep it on a flat panel and clear of fold lines.

Browse current flyer and brochure printing options, then prepare the code at the actual panel size. If the same artwork will be produced in A6, A5 and A4, test the smallest version separately; simple proportional scaling may make the code too small.

QR codes on stickers and labels

Sticker codes can connect packaging to instructions, registration, warranty information or product pages. The applied surface matters: a code can distort when a flexible label wraps around a narrow bottle or crosses a pouch gusset.

• Measure the flat or gently curved label panel.
• Keep the code away from the cut edge.
• Test transparent labels over the real packaging colour.
• Check condensation, scuffing and handling where relevant.
• Use a suitable format from the custom sticker range and test the applied sample.

QR codes on menus

A menu QR code may open a digital menu, ordering page, feedback form or social profile. Place it where diners can reach and scan without moving tableware. Include a readable alternative—such as a short URL or staff assistance—when access to essential information depends on the code.

For printed table menus, review the current menu sheet printing choices and test the code under restaurant lighting. Do not position the code too close to rounded corners, trimming or frequently handled edges.

QR codes on posters and signage

Viewers may stand farther away, so the code generally needs to be larger and supported by a clear instruction. Installation height and safe stopping space matter: do not expect people to scan a code from a moving vehicle or unsafe position.

For rigid promotional or directional applications, compare the display sign printing formats and select a code size based on realistic scan distance.

Colour, white ink and special finishes

Black on white is the safest starting point because it provides strong contrast. Brand colours can work when the dark and light areas remain clearly separated, but pale modules on a light background are risky. Transparent, metallic, holographic and textured materials require additional testing.

Do not place spot UV, foil, embossing, a fold or a perforation over the code. If a premium finish is used elsewhere, preserve a flat, high-contrast scanning area.

Pre-print QR testing checklist

1. Open the destination on several phones and networks.
2. Confirm the page is correct, secure and mobile friendly.
3. Export the final artwork with the code at output size.
4. Print a 100% scale proof on a similar background.
5. Test near and far, straight-on and at slight angles.
6. Test under the expected lighting and after any intended lamination.
7. Check that no trim, fold, seam or mounting hardware enters the quiet zone.
8. Ask another person to scan without being told exactly where to aim.
