Print sizing
QR code sizing is mostly about scan distance. The farther the camera is from the code, the larger the printed code needs to be.
Use the smallest practical payload, strong contrast, and a clear quiet zone so camera apps can detect the code quickly.
Key decisions
Start with 2 cm or 0.8 in
That is a useful minimum for close-range items such as business cards, labels, and table tents.
Scale up for distance
Posters, windows, and wall signage need larger codes because scanners stand farther away.
Protect the quiet zone
Keep a clean margin around the code so nearby images, borders, or text do not interfere with scanning.
Common QR code size targets
| Placement | Suggested minimum | Production note |
|---|---|---|
| Business card or label | 2 cm / 0.8 in wide | Use short URLs and test after printing |
| Flyer or menu | 3-4 cm / 1.2-1.6 in wide | Leave visible instruction text nearby |
| Poster or window sign | 10 cm / 4 in or larger | Test from the actual viewing distance |
Before sending artwork to print
- Print one proof at final size and scan it with multiple phones.
- Avoid glossy reflections across the QR code area.
- Do not place text, logos, or borders inside the quiet zone.
- Use vector files when the artwork will be resized by a designer or printer.
Frequently asked questions
What is the minimum printed QR code size?
For close-range scanning, start around 2 cm or 0.8 inches wide. Increase the size for longer scan distances or dense payloads.
How large should a QR code be on a poster?
Use at least 10 cm or 4 inches wide for typical poster viewing, then test from the actual distance people will scan.
Why do some QR codes need to be larger?
Longer payloads create denser QR codes with smaller modules. Short URLs and simpler data usually scan more easily.
