Error Correction Levels Explained
QR codes have built-in error correction that allows them to remain scannable even when partially damaged, dirty, or obscured. Choose the right level for your needs:
| Level | Recovery | Best For |
|---|---|---|
| L (Low) | 7% of data | Digital screens, clean environments — smallest QR code size |
| M (Medium) | 15% of data | General use — good balance of size and durability |
| Q (Quartile) | 25% of data | Printed materials that may get scratched or folded |
| H (High) | 30% of data | Outdoor signs, packaging, environments with wear and tear |
Tips for Better QR Codes
- Keep data short — shorter text produces simpler, easier-to-scan QR codes. Use URL shorteners for long links.
- Test before printing — always scan your QR code with a phone before printing. Try different scanning apps and distances.
- Maintain contrast — QR codes need high contrast between the dark modules and background. Black on white works best.
- Leave quiet zone — always maintain a white border (quiet zone) around the QR code. Don't crop it too tightly.
- Size matters — for print, a QR code should be at least 2 cm (0.8 inches) wide. For scanning from a distance, make it larger.
Common Use Cases
- Business cards — encode your vCard contact info so people can save your details instantly
- Product packaging — link to product manuals, registration pages, or support resources
- Restaurant menus — link to an online menu, reducing physical contact and printing costs
- Event tickets — encode ticket IDs or event URLs for quick check-in
- Wi-Fi sharing — let guests connect to your Wi-Fi without typing the password
- Marketing materials — add QR codes to flyers, posters, and brochures linking to landing pages
Frequently Asked Questions
You can encode any text data: URLs, plain text, email addresses, phone numbers, Wi-Fi credentials, vCard contact info, or any other text up to 4,296 characters.
Error correction allows a QR code to remain readable even if part of it is damaged or obscured. Level L recovers 7% of data, M recovers 15%, Q recovers 25%, and H recovers 30%. Higher levels produce denser QR codes but are more resilient to damage.
QR codes are generated as PNG images with a white background and black modules. PNG is ideal for web use, printing, and sharing. The image has a 2-module quiet zone (white border) for reliable scanning.
Yes. QR codes can hold up to 4,296 alphanumeric characters. For URLs and short text, this is more than enough. Keep in mind that longer text produces denser, harder-to-scan QR codes — especially at smaller sizes.
