Quick Answer

Use the 10:1 rule: scanning distance should be about 10× the QR code size. Example: for 2 meters distance, aim for ~20 cm QR size. Always test-scan a print proof before production.

Step-by-Step Guide

  1. Determine the expected scanning distance (table, wall, poster, billboard).
  2. Apply the 10:1 rule to estimate minimum size.
  3. Adjust for data density (more data = more modules = needs larger size).
  4. Use error correction wisely (higher EC can increase complexity).
  5. Export in SVG for print or high-DPI PNG (300 DPI).
  6. Print a proof and test-scan in real lighting conditions.

Why QR Code Size Matters

A QR code that's too small won't scan reliably. The golden rule: QR Code Width = Scanning Distance ÷ 10.

Frequently Asked Questions

What is the minimum QR code size for business cards?▼
Common safe minimum is around 0.8–1.0 inch (2–2.5 cm), depending on data density and print quality.
How does scanning distance affect size?▼
Farther distance needs larger codes. Use the 10:1 rule as a baseline.
Does more data require a bigger QR code?▼
Yes—more data increases module density and reduces scannability at small sizes.
