The Thesis project

LucasFonts is the company of Dutch type designer
Luc(as) de Groot.


Luc(as) de Groot is mostly known for his Thesis project. Besides these and other retail fonts available via our web shop, LucasFonts offers every possible kind of service in adapting fonts to your needs and designing customized glyphs or complete typefaces. Contact

With Thesis, Luc(as) de Groot pioneered the concept of the all-purpose type system or superfamily. Thesis provides the user with three compatible styles – TheSans, TheMix and TheSerif – in a range of eight weights including real italics. The Thesis family has been expanded over the years (TheSans and TheMix are now available in three widths). TheSans also offers three ultra-narrow widths and several sub-families.

Taz Wide and Extended

Milestone 2014: Taz Wide and Taz Extended complement the Taz family. 10 weights each with 812 glyphs including Vietnamese (!), stylistic alternates, and 8 figure sets. Like all Taz fonts, they have square dots and punctuation marks, which can be switched to rounded versions for a softer look. Taz Wide has a generous width and saves vertical space. Taz Extended, as one of the widest fonts on the market, makes a vigorous impression and is ideally suited for contemporary editorial design, striking art and advertising..
