D-DIN is a sans serif font family based on the design of DIN typeface that was widely used for traffic, administrative and technical applications. It was defined by the German standards body DIN - Deutsches Institut fur Normung (German Institute for Standardization) in the standard sheet DIN 1451-Schriften (typefaces) in 1931. Similar standards existed for stencilled letters.
Originally designed for industrial uses, the first DIN-type fonts were a simplified design that could be applied with limited technical difficulty. Due to the design's legibility and uncomplicated, unadorned design, it has become popular for general purpose use in signage and display adaptations. Many adaptations and expansions of the original design have been released digitally.
D-DIN font family includes Normal, Condensed and Expanded styles in Regular and Bold weights and also Italic style.
