The two most common font formats in current use are TrueType Fonts (TTF) and OpenType Fonts (OTF). In general, OTF is the newer, more flexible, better-supported, and higher-capability format. However it should be noted that many modern TTF files are actually OTF fonts designed to be compatible with where TTF fonts are expected. ## TrueType Font (TTF) Developed in the 1980's by Apple and Microsoft, TrueType Fonts (TTF) is a standard font format that can be read by computers and printers. While not the first such format, it was a significant enabler for cross-platform consistency, occurring at the expansion of computing and computer-based printing. TTF fonts are defined using quadratic (order 2) Beziers. ## OpenType Font (OTF) Developed in the 1990's by Microsoft and Adobe, OpenType Fonts (OTF) is a successor font format that expanded storage to up to 65,535 characters, and defined characters using cubic (order 3) Beziers, allowing greater control and flexibility of the characters themselves.
