Japanese

The Japanese business card size has dimensions of 91 mm x 55 mm, which converts to approximately 3.58 inches x 2.17 inches. With a surface area of 50.05 sq cm or 7.75 sq inches, it is slightly longer and wider than the ISO A8 size popular in other Asian regions. Like other Asian sizes, it fits within a C6 envelope or sleeve.

This elongated business card format originated as the JIS P 0138-61 standard instituted in Japan in 1961. The proportions match the ISO A8 size but are extended by 1 mm in both dimensions. This allows a bit more space for displaying Japanese characters vertically and English text horizontally. The extended 91 x 55 mm size has become the standard for professional Japanese business cards known as meishi. It provides sufficient area for logos, titles, and contact details in a format that aligns with Japanese industrial and aesthetic standards. The size is sometimes referred to as the Japanese, meishi, or Asian business card size.
