Karben 205 is inspired by the classic, no nonsense DIN, and has a form that follows its highly legible function. Based on a lozenge, it has a clean and pure geometry with even stroke weights. Karben 205 is characterised by its capital A, that retains the lozenge form in preference to a traditional A with oblique sides. Karben 205 is available in four weights, and is also available with character variations as Karben 105.

There are also monospaced variants of both Karben 105 and Karben 205.
