- QR碼可以呈現不同的形狀 圓形或圓形、正方形、長方形或主題形狀。
- 正方形是最常見的QR碼形狀 因為它們的角落、圖案和安靜區使它們成為掃描器最容易和最可靠地準確解碼的形狀。
- 自定義QR碼形狀是可能的,但有一定限制。 保持實際數據矩陣為正方形,在其周圍添加裝飾性圖案或設計元素以保持可掃描性。
- 非傳統形狀的QR碼可能會降低掃描效能 透過影響位置檢測、錯誤更正和代碼方向,特別是在不同設備和掃描應用程序之間。
- 不改變核心的方形結構,來客製化您的QR碼 建立品牌化的QR碼,仍然保持易於掃描。在列印前後進行測試,以便及早解決問題。

常見問題(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.
