The counters and inter-character proportions of Nazanin are characteristic of Persian display lettering and typography. This is particularly true of Nazanin bold, which gives a strong image when used for display purposes. Nazanin possesses fuller, deeper characters than is normally exhibited in Arabic typography: its angled counters contributing to fluid, well-balanced, yet vibrant, letterforms. Originally designed for Farsi typesetting, Nazanin has now become popular for Arabic typesetting as well.
Nazanin is available in two OpenType weights: Nazanin Light and Nazanin Bold. Both of the fonts include Latin glyphs (from Palatino Roman and Palatino Bold, respectively) inside the font files, allowing a single font to set text in both most Western European and Arabic languages.
Nazanin incorporate the Basic Latin character set (Western CP 1252 Latin 1/ANSI and Macintosh US Roman) and the Arabic character set (CP 1256), which supports Arabic, Persian, and Urdu. They include tabular and proportional Arabic, Persian, and Urdu numerals, as well as a set of tabular European (Latin) numerals."
