'''SFNT'''是一套標準化的字體資料結構格式。許多常見的字體格式，例如[[PostScript]]、[[TrueType]]、[[OpenType]]、[[WOFF]]、[[Graphite|SIL Graphite]]<ref name="iana">{{cite web| url=https://www.iana.org/assignments/media-types/application/font-sfnt| title=Type name: application; Subtype name: font-sfnt| publisher=IANA| access-date=2016-06-09| archive-date=2016-06-25| archive-url=https://web.archive.org/web/20160625182623/http://www.iana.org/assignments/media-types/application/font-sfnt| dead-url=no}}</ref>等都使用其作為容器，提供各個字元標準化的定址表、資料結構等。該容器原先是由[[蘋果公司]]為了[[麥金塔電腦]]上的TrueType字體開發的<ref>{{Cite web<br />

由於SFNT制定的特性，其定址以<math>16^4=65536</math>個字元為一個字元表（table）的極限。<ref name="AppleDev">{{Cite web|url=https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6.html#Directory|title=The TrueType Font File|accessdate=2018-12-06|author=|date=|publisher=Apple Developer|archive-date=2018-12-06|archive-url=https://web.archive.org/web/20181206002004/https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6.html#Directory|dead-url=no}}</ref><ref>{{Cite web|url=https://my.oschina.net/wolfcs/blog/140473|title=OpenType字库文件 - WolfCS的个人空间 - 开源中国|accessdate=2018-12-06|author=WolfCS|date=2013-06-25|publisher=开源中国|archive-date=2018-12-06|archive-url=https://web.archive.org/web/20181206001951/https://my.oschina.net/wolfcs/blog/140473|dead-url=no}}</ref><br />
