Calculate Minimum QR Code Size
How the Size Calculation Works
QR code scanability depends mostly on viewing distance. Our calculator uses the industry-standard formulas:
- • Indoor rule: QR Height ≈ Distance ÷ 10
- • Outdoor rule: QR Height ≈ Distance ÷ 8
These formulas ensure the QR code has enough visual size for cameras to recognize the pattern quickly, even in imperfect conditions.
When You Should Increase the QR Code Size
- • Low lighting or dim restaurants
- • Glossy or textured print materials
- • Outdoor glare or reflections
- • Moving viewers (cars, pedestrians)
- • High-value marketing campaigns
