IBM Font Family Classifications
The section defines the family class and subclass values that may be used in the sFamilyClass field of a font’s OS/2 table. A font designer or supplier can assign these values in a font to provide a classification of the font family design. The registered values documented here were originally defined by IBM.
These values classify a font design as to its appearance, but do not identify the specific font family, typeface variation, designer, supplier, size, or metric table differences. It should be noted that some font designs can be classified equally well into more than class or subclass. Such designs should be matched to a classification for which substitution of another font design from the same class or subclass would generally result in a similar appearance of the presented document.
