MAD Serif is the more elegant side to the MAD family, with a similar harshness to MAD Sans but with a shape that is more graceful and features that become sharper and delicate at points. It has an air of sophistication at certain sizes that give way to crudeness at larger sizes.

Like MAD Sans, it feels rough but is surprisingly balanced and in it’s proper spot. Ready for use in different sizes to give flair to headlines and an interesting texture to body copy, in twelve styles ranging from Light to Bold Italic in both Open and Fill Weights.

During his time at the Werkplaats Typografie, Dries was among CAD drawings and a fascination for these program’s inherent typeface arose. These two type families are a reinterpretation that tries to make the most of their grid-based nature — they are a tribute to historical and forgotten form.

MAD is an acronym for Machine Aided Design, a direct reference to CAD (Computer-Aided Design), which reveals the typeface’s starting point. Since early printing of CAD plans were done with plotters that drew every single line of the instruction, special typefaces had to be designed for the dimensions and other information. These were constructed out of lines and not outlines of shapes. With their rendering dictated by the resolution of the output device, their final form was not fixed.
