TTF fonts are still much more popular than OTF fontsĥ. For designers, both amateur and professional, the main useful difference between OTF and TTF is in the advanced typesetting features. TTF font files are often much bigger compared to OTF font filesĤ. TTF fonts depends solely on a glyph table while OTF fonts can either have glyph tables or CCFģ. TTF is the file extension for TrueType fonts while OTF is the extension for OpenType fonts.Ģ. You do not need to choose one over the other as they can be used together in creating documents or printing layouts.ġ. The good news is that there is really no issue for the end user as almost all modern applications that use fonts are able to work with both TTF and OTF files. Since there is really no reason to stop using TTF in creating new fonts, most font makers still stick to what they know works, even if it is inferior to the alternative. The reason behind this popularity is the simplicity of making TTF fonts compared to OTF fonts that use CCF. It may be taking much longer than expected, but the number of OTF fonts is already on the rise. Although it may not have a very significant effect on your computer, it is also worth noting that the use of CCF in OTF could lead to file sizes that are significantly smaller, given that no special features are used in the font.ĭespite the proven superiority of OTF fonts, especially when using CCF, the use of TTF fonts is still very prolific. They may contain any combination of TrueType, CFF-OTF/T1, and bitmapped fonts, although nobodys really done bitmapped fonts since bitmap/T1 pairs fell out of favor due to the introduction of OTF containers. otf files if available theyre likely more modern and more complete. OTF also adds a few smartfont features, on top of the sfnt structure that is being used by TTF, to add additional language support to the fonts. So in answer to the original question: if youre talking about. The cubic Bezier splines used by CCF allow for fewer points to be used in defining how a character would look, compared to the quadratic Bezier splines used by TTF fonts. TTF depends solely on glyph tables that define how each character looks, while OTF is able to use glyphs along with CCF (Compact Font Format) tables. TTF stands for TrueType Font, a relatively older font, while OTF stands for OpenType Font, which was based in part on the TrueType standard.Ī significant difference between the two is in their capabilities. The ability to keep extra characters besides the usual ones (A-Z, 0-9, punctuations, and symbols. An example being that the former has a format capable of storing as much as 65,000 characters. OTF was designed to enable more functions than TTF. TTF and OTF are extensions that are used to indicate that the file is a font. OTF was also a hybrid creation with display font and printer font data packaged in a single platform. Many people ask us “What is the difference between True Type Fonts vs Open Type Fonts?”.
