Print QR Sizing
A QR Code that cannot be scanned is a printed decoration. Size, resolution and format determine whether the code works at the intended scanning distance — every time.
Definition
Print QR sizing covers the dimensional, resolution and format specifications required for QR Codes to scan reliably in printed applications. A QR Code that looks correct on screen may fail to scan when printed at insufficient size, at low resolution, or when scaled from a raster format — all common errors in QR Code print production.
The Scanning Distance Rule
The fundamental sizing principle for print QR Codes is the 10:1 rule: the QR Code should be at least one-tenth of the distance from which it will typically be scanned.
| Expected scanning distance | Minimum QR Code size | Typical application |
|---|---|---|
| 20–30 cm (close range) | 2 cm × 2 cm | Table menu, receipt, business card, product label |
| 50 cm | 5 cm × 5 cm | A4 flyer, small poster, brochure page |
| 1 metre | 10 cm × 10 cm | A3 poster, shelf display, event programme cover |
| 2–3 metres | 20–30 cm × 20–30 cm | A1 poster, exhibition display, retail signage |
| 5+ metres | 50+ cm × 50+ cm | Large format outdoor, stage backdrop, banner |
These are working minimums. When in doubt, make the QR Code larger — there is no maximum size, and a larger code at a given distance is always easier to scan than a smaller one.
File Format: SVG for Print, PNG for Digital
This is the single most important technical decision in QR Code print production:
SVG (Scalable Vector Graphics) — use for all print applications
Vector format. Scales to any size without quality loss. A QR Code in SVG can be placed on a business card or a billboard from the same file — the output quality is identical at any size. Required for professional print production.
PNG (Portable Network Graphics) — use for digital applications only
Raster format. Has a fixed pixel dimension. Looks sharp at its native size or smaller. Becomes pixelated when scaled beyond its native resolution. Appropriate for websites, presentations, emails and social media where the display size is known and fixed.
The critical error: downloading a QR Code as PNG at its default export size (often 300–500px) and then scaling it up in a design application for large-format print. The result is a blurred, pixelated code that may not scan. Always use SVG for print.

Resolution for Raster Print Production
If SVG is not possible and raster output is required (some older print workflows only accept TIFF or high-resolution PNG), the QR Code must be exported at sufficient resolution for the intended print size:
- Standard print resolution: 300 DPI at the final intended print size
- High quality / premium print: 600 DPI at the final intended print size
- Calculate required pixel dimensions: print size in inches × DPI = required pixel dimension
Example:
A QR Code to be printed at 5cm × 5cm = approximately 2 inches × 2 inches at 300 DPI requires a 600px × 600px raster file minimum. At 600 DPI, 1,200px × 1,200px.
Quiet Zone: The Mandatory White Border
Every QR Code requires a clear white border — called the quiet zone — around all four sides. The quiet zone allows the scanner to identify the code boundaries and distinguish the code from surrounding content.
Minimum quiet zone: 4 module widths on all sides (a "module" is one square unit in the QR Code matrix). In practice: ensure there is visible white space between the QR Code edge and any surrounding text, graphics or background colour.
Common quiet zone errors:
- Placing the QR Code directly against a dark background with no white border
- Text or design elements placed inside or touching the code boundary
- Clipping the quiet zone when cropping the QR Code image in a design application
Testing Before Mass Production
Before committing to mass print production, always test scan a physical proof at the intended final size:
- Print a proof at actual production size (not scaled on screen)
- Scan with the native camera app on iOS
- Scan with the native camera app on Android
- Scan from the expected viewing distance
- Verify the correct destination opens
If the code fails to scan on physical proof, increase the size, increase resolution or switch to SVG before going to production.

FAQ
What is the minimum size for a QR Code in print?
2cm × 2cm minimum for close-range scanning (20–30cm). Apply the 10:1 rule: minimum code size = expected scanning distance ÷ 10. For 1 metre scanning distance: 10cm × 10cm minimum. When in doubt, go larger.
Should I use SVG or PNG for a QR Code in print?
Always SVG for print. SVG scales to any size without pixelation — essential for professional print production. PNG is raster-based and becomes pixelated when scaled beyond its native resolution. Use PNG only for digital applications (websites, email, presentations) where display size is fixed.
