Frequently Asked Questions
What can a QR code encode?
QR codes can encode URLs, plain text, contact information (vCard), Wi-Fi credentials, phone numbers, SMS messages, email addresses, and more. The most common use case is encoding a URL for quick mobile scanning.
What is QR code error correction?
QR codes have built-in error correction (L, M, Q, H levels — 7% to 30% data recovery). Higher error correction allows the code to be read even if partially obscured or damaged, but also makes the code denser.
How large should a printed QR code be?
The minimum printable size for reliable scanning is about 2 × 2 cm (0.8 × 0.8 inches) at typical scanning distances. For posters or outdoor use, scale to at least 5 × 5 cm. A 10:1 ratio of distance to size is a good rule.
