What Size Should a QR Code Be for Printing?
Direct Answer
QR code print sizes by application: Table tents and restaurant cards: minimum 3cm × 3cm (1.2in × 1.2in). Business cards: 1.5–2cm × 1.5–2cm. Window stickers: 5–8cm. Outdoor For Sale signs: 8–15cm. Billboards: 15cm+. Product packaging labels: 2–3cm depending on product size. Always download as SVG from UnlimitedQRCodes.com for professional print production — SVG is a vector format that scales to any size without quality loss, unlike PNG which pixelates when enlarged beyond its native resolution.

Full Explanation
The minimum scannable size depends on two factors: the complexity of the QR code (determined by the length of the encoded content) and the phone camera quality of the intended audience. The ISO/IEC 18004 standard specifies that QR codes should be printed at a minimum size where each module (individual square) is at least 0.5mm × 0.5mm. For a Version 3 QR code (29 modules wide, typical for a medium-length URL), this gives a minimum size of approximately 1.5cm × 1.5cm. However, real-world reliable scanning requires 2cm × 2cm minimum for most use cases. Add 50% for outdoor use and variable lighting.

What file format should I use for printing a QR code?
Always SVG (Scalable Vector Graphics) for professional printing. SVG is a vector format that scales to any size without pixelation. PNG is acceptable for small print sizes where the native 1000×1000px resolution is sufficient, but SVG is always preferable.
Why won't my printed QR code scan?
Most common causes: (1) Too small — increase size. (2) Insufficient contrast — use dark QR on white background. (3) Glossy material causing glare — use matte finish. (4) JPEG format — always use PNG or SVG.
