# Microsoft Sans Serif

Microsoft Sans Serif is a sans-serif typeface introduced with early Microsoft Windows versions. It is the successor of MS Sans Serif, formerly Helv, a proportional bitmap font introduced in Windows 1.0. Both typefaces are very similar in design to Arial and Helvetica. The typeface was designed to match the MS Sans bitmap included in the early releases of Microsoft Windows.

## History

Microsoft Sans Serif's predecessor is Helv (a shortened form of Helvetica), a bitmap font included with Windows 1.0 and later. In Windows 3.1, the bitmap font was renamed MS Sans Serif. "Helv" is still a valid alias for MS Sans Serif. OS/2 and its successor ArcaOS still name the font "Helv".
MS Sans Serif is the default system font on Windows 3.0, Windows 3.1, Windows 95, Windows NT 4.0, Windows 98, and Windows ME. A Euro symbol was added to this font for the release of Windows 98. MS Sans Serif is available in the font sizes 8, 10, 12, 14, 18, and 24. When changing the DPI settings in Windows 95 or later, Windows loads a different MS Sans Serif font, historically called the "8514" variant, which adds sizes 23 and 30 points (high DPI versions of sizes 18 and 24 respectively). Also, according to the strings hidden in the .FON file (on the original raster/bitmap variant), it is seen that the font was designed by Microsoft Corporation in 1987 (font sizes 8, 10, 12 and also a portion of the 8514/a version), also in 1985 by Xiphias, Los Angeles, CA (font sizes 14, 18, 24), also the 8514 version contains typefaces designed by Bitstream Inc. in 1989.

## Description

Microsoft Sans Serif is a TrueType font that is designed as a vectorized, metric-compatible variant of MS Sans Serif, distributed with Windows 2000 and later. This font also contains most glyphs shipped with any version of Windows until Windows Vista, excluding fonts supporting East Asian ideographs. The PostScript font name is MicrosoftSansSerif.
Despite being a vectorized replacement, there are subtle design changes. One example is the capital R - where in the original MS Sans Serif it was designed in the style of Helvetica, in Microsoft Sans Serif it becomes a compromise between Helvetica and the straight-diagonal descender in Arial; the descender curves at the top and is a straight diagonal at the bottom. Other examples include the tail in the lowercase a being shortened to a vertical stem, the top of the stem on the lowercase f curving down instead of horizontally, the hook at the descenders of lowercase y and j curving up, and the strokes in the middle of digit 8 intersecting at a different angle.
Version 1.10 of the font includes 1119 glyphs (1209 characters, 26 blocks), supporting Unicode ranges Alphabetic Presentation forms, Arabic, Arabic Presentation forms A-B, Cyrillic, General Punctuation, Greek and Coptic, Hebrew, Latin Extended-A, Latin Extended-B, Latin Extended Additional, Mathematical Operators, Thai.

OpenType features includes init, isol, medi, fina, liga for default Arabic script.

New OpenType scripts include Arabic MAR script. Additional OpenType features includes rlig for Arabic scripts.
Version 5.00 (supplied with Windows Vista and Windows Server 2008) includes 3053 glyphs (2788 characters, 36 blocks), which extended Unicode ranges to include Arabic Supplement, Combining Diacritical Marks Supplement, Combining Half Marks, Latin Extended-C, Latin Extended-D, Phonetic Extensions, Phonetic Extensions Supplement, Specials, Superscripts and Subscripts.

MS Sans Serif was given a PANOSE number that indicates it has "cove" serifs, while the PANOSE number for Microsoft Sans Serif indicates that is a sans serif.
Glyphs from Microsoft Sans Serif are also used in the typeface Kartika.

## Non-Microsoft operating systems

On October 16, 2007, Apple announced on their website that the next version of Mac OS X v10.5 ("Leopard"), would include Microsoft Sans Serif. Leopard also ships with several other previously Microsoft-only fonts, including Tahoma, Arial Unicode, and Wingdings. Microsoft Sans Serif has been included with all macOS versions since.
Retail versions of the font are sold through Ascender Corporation.
