arial

Arial (also called Arial MT) is a sans-serif typeface and set of computer fonts in the neo-grotesque style. Fonts from the Arial family are included with all versions of Microsoft Windows after Windows 3.1, as well as in other Microsoft programs, Apple's macOS, and many PostScript 3 printers.
The typeface was designed in 1982 by Robin Nicholas and Patricia Saunders, for Monotype Typography.
Each of its characters has the same width as that character in the popular typeface Helvetica; the purpose of this design is to allow a document designed in Helvetica to be displayed and printed with the intended line-breaks and page-breaks without a Helvetica license. Because of their similar appearance, both Arial and Helvetica are commonly mistaken for each other.
The most widely used and bundled Arial fonts are Arial Regular, Italic, Bold, and Bold Italic; the same styles of Arial Narrow; and Arial Black. More recently, Arial Rounded has also been widely bundled.
In Office 2007, Arial was replaced by Calibri as the default typeface in PowerPoint, Excel, and Outlook.
