Frank-Rühl (or Ruehl) is the ubiquitous Hebrew text font style. There are many fonts that belong to this style, and all are based on an early 20th-century design by Raphael Frank. Some of the fonts are actually called Frank-Rühl (or Ruehl) and some are not. It was originally designed in a single weight.

Bitstream developed Frank Ruehl for the Microsoft Windows operating system. The font is encoded with a Microsoft defined Hebrew character set, Hebrew Code Page 1255. Within the TrueType fonts, the characters are assigned Unicode character IDs. The font includes Hebrew characters, and Latin glyphs from Dutch 801 bold.
