Iranian

The Iranian business card size has dimensions of 85 mm x 48 mm, which converts to approximately 3.3 inches x 1.9 inches. With a surface area of 40.8 sq cm or 6.32 sq inches, it has a more elongated, horizontal profile. This size can fit within a custom envelope around 4 x 6.5 inches.

This slim card format originated as an Iranian Industrial Standard in 1997 as the country sought to standardize paper sizes. The proportions match Iran's standard A5 paper size, but shortened to create a narrow business card optimized for Farsi text. The elongated shape allows Farsi characters to be written top-to-bottom while accommodating English text beside. The 85 x 48 mm dimension fits key contacts without excess space. The proportional link to A5 paper enables easy printing. The size is sometimes referred to as the Iranian, Farsi, or Middle Eastern business card format for its specialized dimensions suiting the region.
