QR Code Best Practices: Design & Implementation
Design Principles for Scannable QR Codes
Size Requirements:
- Minimum: 2cm × 2cm (0.8" × 0.8") for close viewing
- Recommended: 3-4cm × 3-4cm (1.2-1.6" × 1.2-1.6")
- Distance rule: QR size = viewing distance ÷ 10
- Example: Viewed from 3 meters away = 30cm QR code
Contrast & Colors:
- ✅ Best: Black on white (highest contrast)
- ✅ Good: Dark blue on white, dark green on white
- ⚠️ Risky: Light colors, low contrast combinations
- ❌ Avoid: White on black (inverted), yellow on white, pastels
- Rule: Dark foreground, light background
Quality Standards:
- Generate as vector (SVG) for print, not raster (PNG/JPG)
- Print resolution: Minimum 300 DPI
- Avoid compression artifacts
- Test scan before mass printing
Call-to-Action (CTA):
- ✅ Specific: "Scan for Menu" (tells what they get)
- ✅ Action-oriented: "Scan to Save 15%" (creates urgency)
- ✅ Benefit-focused: "Scan for Free Guide" (shows value)
- ❌ Generic: "Scan Here" (no motivation)
- ❌ No CTA: Just QR code (confusing)
Strategic Placement
Physical Considerations:
- Height: Eye level (140-160cm) for standing, table level for sitting
- Lighting: Well-lit areas, avoid glare or shadows
- Surface: Flat, smooth surfaces scan better than curved/textured
- Accessibility: Easy to approach, no obstacles
- Protection: Laminate outdoor QR codes, protect from weather
Context Matters:
- Restaurants: Table tents, menus, receipts
- Retail: Product displays, checkout counters, windows
- Events: Entrance, registration, sponsor booths
- Real estate: Yard signs, brochures, open house signs
- Transportation: Bus stops, subway ads (quick scan time)
