QR Code Best Practices for Beginners
QR Code Best Practices for Beginners
Essential guidelines to create QR codes that scan reliably, look professional, and deliver results.
Getting Started Right
Creating an effective QR code is more than just generating a square pattern. Following best practices ensures your QR codes work reliably, look professional, and achieve your goals—whether that's driving website traffic, sharing contact information, or connecting customers to your content.
This guide covers the essential best practices every beginner should know. If you're completely new to QR codes, start with our beginner's guide to understanding QR codes first.
Sizing Your QR Code
Size is one of the most critical factors for QR code success. Too small, and it won't scan. Too large, and it may overwhelm your design.
The 10:1 Distance Rule
A simple rule: the QR code should be approximately 1/10th of the expected scanning distance.
| Scanning Distance | Minimum QR Size | Use Case |
|---|---|---|
| 20 cm (8 in) | 2 cm (0.8 in) | Business cards, product labels |
| 1 meter (3 ft) | 10 cm (4 in) | Posters, table tents |
| 3 meters (10 ft) | 30 cm (12 in) | Banners, storefront windows |
| 10 meters (33 ft) | 1 meter (3 ft) | Billboards, large displays |
Pro Tip
When in doubt, go larger. A slightly oversized QR code will still scan, but one that's too small won't work at all.
Contrast and Color Guidelines
Proper contrast between foreground and background is essential for scanners to read your QR code correctly.
Essential Color Rules
- Dark on light: Use dark foreground colors on light backgrounds
- Minimum contrast: Maintain at least 4:1 contrast ratio
- Avoid: Light colors on light backgrounds (yellow on white)
- Avoid: Dark colors on dark backgrounds (navy on black)
- Never invert: Light foreground on dark background rarely works
Safe Color Combinations
- • Black on white
- • Dark blue on white
- • Black on light yellow
- • Dark green on cream
- • Yellow on white
- • Light gray on white
- • White on black
- • Red on green
The Quiet Zone
The quiet zone is the white space surrounding your QR code. It's not just aesthetic—it's essential for scanning.
- Minimum size: 4 modules (small squares) wide on all sides
- Color: Should match the background color of the QR code
- Don't crowd: Keep text, logos, and other elements outside this zone
- Borders: If using a border, it should be outside the quiet zone
Common Mistake
Placing the QR code too close to edges or other design elements is a top cause of scanning failures. Always maintain the quiet zone.
Testing Your QR Codes
Never skip testing. A QR code that doesn't scan is worse than no QR code at all.
Testing Checklist
- Scan with at least 3 different smartphones (mix of iOS and Android)
- Test in various lighting conditions (bright, dim, artificial)
- Try scanning from different angles
- Test at the expected scanning distance
- Print a test copy at final size before mass printing
- Verify the destination URL loads correctly
- Have someone unfamiliar with the code test it
What to Check
- Does the code scan on the first attempt?
- Does the destination load quickly?
- Is the destination mobile-friendly?
- Is the content what users expect?
Common Mistakes to Avoid
1. No Call to Action
Always tell users what they'll get by scanning. "Scan for 10% off" beats a lonely QR code.
2. Linking to Non-Mobile Pages
QR codes are scanned on phones. The destination must be mobile-optimized.
3. Using Static Codes for Campaigns
Use dynamic codes for marketing so you can track performance and update destinations.
4. Poor Placement
Avoid placing QR codes on curved surfaces, reflective materials, or in low-light areas.
5. Broken Links
With static codes, a changed URL means a useless QR code. Dynamic codes solve this.
Dynamic vs. Static: Which to Choose
For most beginners, dynamic QR codes are the better choice. Here's why:
Dynamic (Recommended)
- Change destination without reprinting
- Track scan analytics
- Fix mistakes after printing
- Smaller, simpler code pattern
Static
- Free forever
- Works offline (for embedded data)
- No dependency on external service
- Cannot be changed once printed
