How to Choose a QR Code Size for Print
There is no universal print size. The reliable choice depends on scanning distance, the amount of encoded data, the material, lighting and the phones your audience uses.

Start with scanning distance
A business card is scanned close up while a poster may be scanned from several steps away. Make the code larger as the expected distance increases, and ensure a person can comfortably frame the whole code in their camera.
Account for pattern density
Long URLs and detailed contact cards create more modules. At the same physical size, each module becomes smaller and harder to reproduce. Use the final payload during testing, remove unnecessary text and enlarge a dense code rather than compressing it.
Protect the quiet space
Keep a clear, consistent light border around all four sides. Nearby text, artwork, folds or trim can interfere with detection. Do not crop the margin supplied by the generator when placing the asset in design software.
Export and proof correctly
SVG is appropriate when artwork must scale without pixelation. PNG is suitable when exported at adequate resolution and not enlarged later. Always test the placed artwork and a real proof on the final material.
- Place the final code at its intended dimensions.
- Check that the layout did not crop or distort it.
- Print one proof using the production material and finish.
- Scan from realistic distances with multiple phones.
