East Asian

The East Asian business card size has dimensions of 90 mm x 54 mm, which converts to approximately 3.54 inches x 2.12 inches. With a surface area of 48.6 sq cm or 7.53 sq inches, it has a more elongated, horizontal profile compared to other formats. It can fit inside a C6 envelope or sleeve like the Western European and Eastern European sizes.

This business card size originated in parts of East Asia including China, Hong Kong, and Singapore. It matches the Class 2 paper size defined in the Chinese National Standard GB/T 148-1997. The proportions are optimized for displaying Chinese characters vertically and English text horizontally. The 90 x 54 mm dimension fits slightly more content than the ISO A8 size popular in other Asian regions. It’s sometimes referred to as the Chinese, Hong Kong, or Singaporean business card size. Overall, the elongated format provides a unique look and feel that conforms to East Asian aesthetics and writing conventions.
