QR Code Best Practices
Follow these rules for scannable QR codes.
High Contrast
Dark foreground on light background.
Black on white is best.
Light on dark may not scan.
Adequate Size
Minimum size depends on scanning distance.
1 inch at 6 inches away (business card).
4 inches at 3 feet away (flyer).
8 inches at 10 feet away (poster).
Test Before Printing
Scan with multiple phones (iPhone and Android).
Test from intended distance.
Test in different lighting conditions.
Provide Context
Tell people what the QR code does.
“Scan for menu” or “Scan to call us”.
Increases scan rates significantly.
Track Scans
Use a URL shortener with analytics.
Create unique QR codes for each campaign.
Measure which marketing channels work.
Common QR Code Mistakes
Even experienced marketers make these errors.
Avoid them for scannable codes.
Mistake 1: Low Contrast
Light gray on white background.
Phone cameras cannot distinguish patterns.
Always use high contrast.
Mistake 2: Too Small
Printing a 100×100 pixel code on a billboard.
Drivers cannot scan from far away.
Match size to viewing distance.
Mistake 3: No Quiet Zone
QR code touching other design elements.
Scanners need white space around the code.
Add at least 4 modules of padding.
Mistake 4: Broken Destination
QR code links to a 404 page.
Always verify the destination works.
Test every QR code before printing.
Mistake 5: Logo Too Large
Logo covering 40% of the code.
Scanners cannot read the pattern.
Keep logo under 20% of code size.
