- Medium (M) - Recovers 15% damaged data. Good balance of size and reliability.
- Quartile (Q) - Recovers 25% damaged data. More reliable for print materials.
- High (H) - Recovers 30% damaged data. Most reliable, largest QR codes.

Static vs Dynamic QR Codes – What's the Difference?
📌 Static QR Codes
- Permanent – Content cannot be changed once generated
- Free – No ongoing costs or subscriptions
- Self-contained – All data stored directly in the QR code
- No tracking – No analytics or scan data
- Works offline – No internet needed to scan
Best for: Print materials, business cards, static information that won't change
🔄 Dynamic QR Codes
- Editable destination – Can change the target URL after printing
- Analytics tracking – See scan counts, locations, devices
- Usually paid – Requires subscription service
- Redirect-based – QR code points to a short URL that redirects
- Requires internet – Redirect service must be online
Best for: Marketing campaigns, A/B testing, content that may need updates
Our generator creates static QR codes – permanent, free, and self-contained. Perfect for most use cases where content won't change.
How QR Codes Work (Simple Explanation)
QR (Quick Response) codes are two-dimensional barcodes that store information in a grid of black and white squares. Here's how they work:
- Data encoding – Information (text, URL, etc.) is converted into binary and arranged in a grid pattern
- Pattern recognition – Three corner squares help scanners orient and read the code
- Error correction – Redundant data allows scanning even if partially damaged
- Scanner decodes – Camera apps read the pattern and convert back to original data
QR codes support many formats: URLs, plain text, contact info (vCard), WiFi credentials, email addresses, phone numbers, and more.
History: Developed in 1994 by Denso Wave for tracking automotive parts. Now universal for mobile interactions.
What Size Should a QR Code Be for Printing?
For reliable scanning, printed QR codes need adequate size based on viewing distance:
| Use Case | Recommended Size | Scan Distance |
|---|---|---|
| Business cards | 1.5–2 cm (0.6–0.8 inches) | 10–15 cm |
| Flyers & brochures | 2–3 cm (0.8–1.2 inches) | 30–50 cm |
| Product packaging | 2–3 cm (0.8–1.2 inches) | 30–60 cm |
| Posters (A3/A2) | 3–5 cm (1.2–2 inches) | 1–2 meters |
| Billboards | 10+ cm (4+ inches) | 5+ meters |
Pro tip: Always test-print at final size and scan from intended distance before mass production.
Common QR Code Mistakes to Avoid
📏 Too small
QR codes under 1.5 cm may not scan reliably. Follow size guidelines above.
🎨 Low contrast
Light colors on light backgrounds fail. Use dark code on white background.
🖼️ Overcrowded design
Placing QR codes on busy backgrounds reduces scan success.
📄 Damaged prints
Creases, folds, or smudges can break scanning. Use error correction.
🔗 Very long URLs
Long URLs create dense QR codes. Use URL shorteners first.
❌ No testing
Always test QR codes with multiple devices before finalizing.
How Much Data Can a QR Code Store?
QR codes have different capacities based on version (size) and error correction level. Maximum characters per QR code (version 40, low error correction):
| Data Type | Max Characters | Example |
|---|---|---|
| Numeric | 7,089 characters | Phone numbers, IDs |
| Alphanumeric | 4,296 characters | URLs, product codes |
| Binary (bytes) | 2,953 bytes | Small images, encrypted data |
| Kanji/Kana | 1,817 characters | Japanese text |
Note: Higher error correction reduces capacity. For most uses (URLs, contact info), capacity is more than enough.
