QR Code Size Recommendations for Easy Scanning

The size of your code affects whether people can scan it. Here's what works best:

Optimal Sizes by Format:

• Business cards, brochures: At least 2 x 2 cm (0.8 inches)
• Posters, billboards: Use 1 cm of code size per 1 m of viewing distance
• Digital screens: At least 240 x 240 pixels for good resolution

Sizing Depends On:

• Viewing distance (further = larger code)
• Phone camera quality (older models need larger codes)
• How much data is in the code (short URLs are better)

Don't shrink codes to make designs look better. Codes must stay large enough to scan easily.

Tip from Epic Brander: "Make sure your code is big enough for easy scanning from the expected distance."

QR Code Placement Best Practices

Where you place QR codes affects if people see and use them.

Best Placements:

• Posters/flyers: Center or at user eye-level
• Product packaging: Front or back panel—avoid folds
• Business cards: Back or corner away from text

Avoid:

• Edges or rounded corners
• Shiny areas or spots with glare
• Busy images behind the code—use high contrast backgrounds

Industry Tips:

• Retail: Entryway, checkout counter
• Events: Registration booths, banners

From Epic Brander: "Avoid placing codes in areas that can be bent, folded or are hard to see."

QR Code Printing Specifications You Can't Ignore

Low print quality leads to scan failures. Use these specs:

Must-Have Print Settings:

• Resolution: At least 300 DPI (dots per inch)
• Colors: Use dark codes on light backgrounds
• Quiet zone: Leave a 4-unit blank border around the code
• Error correction: Use medium or high level to keep it readable even if damaged

Best Print Materials:

• Matte finishes reduce glare
• Laminated paper, vinyl, or metal for outdoor durability

Test how your print looks across formats—like flyers, labels, or signage—to ensure quality.

Epic Brander says: "Pay careful attention to contrast and print quality."

QR Code Mobile Optimization

Most QR codes are scanned on phones. Your setup must work well on mobile.

Make It Mobile-Friendly:

• Use short URLs to keep code data small and fast to scan
• Don't embed big image files
• Landing page must be responsive and load fast (<3s)

Test For:

• Multiple screen sizes
• Old and new phone models
• Differences between iOS and Android

Advice from Epic Brander: "Design with mobile scanning in mind; and always test across devices."

QR Code Testing Before Launch

Before making QR codes public, you MUST test them.

Testing Checklist:

• Test with multiple devices – both old and new models
• Try from different distances and angles
• Use various lighting conditions
• Scan after printing to see if appearance changes scan results

Tools:

• Native phone camera
• QR code scanning apps or browser extensions
• Online code checkers

Catch problems before users find them.

Epic Brander reminds: "Scan-test every printed code in different environments by different people."

QR Code Landing Page Design Tips

Where your QR code leads matters. If the landing page is bad, users leave.

Essential Features:

• Clear message matching the QR code promise
• Mobile-first responsive design
• Fast loading speed—under 3 seconds
• One strong call to action (CTA)
• Cut out clutter—less is more

Good landing pages complete the QR code journey with helpful content or deals.

Make sure to connect pages with analytics so you can track what users do.

QR Code Call to Action Examples That Work

QR codes work best when paired with clear, direct CTAs.

CTA Examples:

• "Scan to get 10% off your next purchase."
• "Scan to view our event schedule."
• "Download our free app."
• "Scan for instant access to our menu."

CTAs should sit right next to or surrounding the code, in bold fonts that draw the eye.

CTA Goals:

• Lead magnets like email signups
• Bonus content
• App downloads
• Special offers

Epic Brander shares brand examples of well-used CTAs generating big engagement.

FAQ

Q: How big should a QR code be on a billboard?

A: As a rule of thumb, use 1 cm of QR code size for every 1 meter of viewing distance. For billboards that are viewed from far away, this means significantly larger codes.

Q: Can I customize the colors of my QR code?

A: Yes, but ensure high contrast between the code and background. Dark codes on light backgrounds work best to ensure scannability.

Q: Why is testing QR codes necessary?

A: Testing ensures that your QR codes work across different devices, scanning apps, and in various real-world conditions, preventing user frustration.
