A font family is a group of fonts that have similarities in design. One member of the font family may be bold, while another member of the same family may be italic (these characteristics are also referred to as font style). Families are generally grouped into categories based on design specifications such as serifs, fonts that resemble handwriting, or even its proportional spacing. The five generic font families consist of fonts in the categories of serif, sans-serif, cursive, fantasy and monospace. There are other font families such as Times, Script, Arial and Courier to name but a few of the more popular families.
