QR Code Best Practices

Design Best Practices

Your QR code needs to be scannable and visually appealing. Here's how:

Size Matters

• Minimum: 2cm x 2cm (0.8" x 0.8")
• Recommended: 3cm x 3cm for print materials
• Billboard/Large format: Scale proportionally to viewing distance

Contrast & Color

• Dark pattern on light background works best
• Maintain at least 40% contrast ratio
• Test colored codes on multiple devices
• Avoid very light colors that cameras struggle to detect

Placement Strategy

Physical Location

• Eye level is ideal (easier to scan)
• Well-lit areas only
• Flat surfaces when possible
• Away from reflective materials

Context is King

• Always include a call-to-action
• Explain what happens after scanning
• Make the value proposition clear
• Consider the user's situation

Technical Optimization

Error Correction

QR codes have built-in redundancy. Choose the right level:

• Low (7%): Maximum capacity, perfect conditions
• Medium (15%): Standard use case
• High (30%): Outdoor, curved surfaces, logo overlay

Landing Page Optimization

• Mobile-first design is essential
• Fast loading times (<2 seconds)
• Clear above-the-fold content
• Single, clear call-to-action
