常见问题(FAQ)
Can QR codes be different shapes?
Yes, QR codes can have customized shapes and designs, but the actual data matrix should remain square for reliable scanning. You can soften the corners, choose a pattern style, colors, frames, and add a logo while preserving the QR code's structure. Designs that alter or remove key scanning elements may reduce compatibility across devices and scanners.
Why are QR codes usually square?
QR codes are square because the international QR code standard is based on a square grid that contains data modules, finder patterns, alignment patterns, and a quiet zone. This structure allows scanners. to quickly detect the code's orientation and decode it accurately from different angles, distances, and lighting conditions. The square shape also maximizes data capacity while maintaining fast and error-free scanning.
What is the best shape for a QR code?
A square QR code is the best shape for compatibility, scan speed, and reliability. It follows the ISO standard used by virtually all QR code scanners and smartphone cameras. This ensures consistent performance across print and digital media.
If you want a branded look, customized the colors, pattern and eye styles, frame, and logo, instead of changing the entire square strcuture.
