The 'OS/2' table consists of a set of metrics that are required by OS/2 and Windows. It is not used by the Mac OS.

Type	Name of Entry	Comments
USHORT	version	table version number (set to 0)
SHORT	xAvgCharWidth;	average weighted advance width of lower case letters and space
USHORT	usWeightClass;	visual weight (degree of blackness or thickness) of stroke in glyphs
USHORT	usWidthClass;	relative change from the normal aspect ratio (width to height ratio) as specified by a font designer for the glyphs in the font
SHORT	fsType;	characteristics and properties of this font (set undefined bits to zero)
SHORT	ySubscriptXSize;	recommended horizontal size in pixels for subscripts
SHORT	ySubscriptYSize;	recommended vertical size in pixels for subscripts
SHORT	ySubscriptXOffset;	recommended horizontal offset for subscripts
SHORT	ySubscriptYOffset;	recommended vertical offset form the baseline for subscripts
SHORT	ySuperscriptXSize;	recommended horizontal size in pixels for superscripts
SHORT	ySuperscriptYSize;	recommended vertical size in pixels for superscripts
SHORT	ySuperscriptXOffset;	recommended horizontal offset for superscripts
SHORT	ySuperscriptYOffset;	recommended vertical offset from the baseline for superscripts
SHORT	yStrikeoutSize;	width of the strikeout stroke
SHORT	yStrikeoutPosition;	position of the strikeout stroke relative to the baseline
SHORT	sFamilyClass;	classification of font-family design.
PANOSE	panose;	10 byte series of number used to describe the visual characteristics of a given typeface
ULONG	ulUnicodeRange1	Field is split into two bit fields of 96 and 36 bits each. The low 96 bits are used to specify the Unicode blocks encompassed by the font file. The high 32 bits are used to specify the character or script sets covered by the font file. Bit assignments are pending. Set to 0 Bits 0–31
ULONG	ulUnicodeRange2	Bits 32–63
ULONG	ulUnicodeRange3	Bits 64–95
ULONG	ulUnicodeRange4	Bits 96–127
CHAR	achVendID[4];	four character identifier for the font vendor
USHORT	fsSelection;	2-byte bit field containing information concerning the nature of the font patterns
USHORT	usFirstCharIndex	The minimum Unicode index in this font.
USHORT	usLastCharIndex	The maximum Unicode index in this font.
USHORT	sTypoAscender
USHORT	sTypoDescender
USHORT	sTypoLineGap
