Kabel belongs to the "geometric" style of sans-serifs, which was becoming popular in Germany at the time of Kabel's creation. Based loosely on the structure of the circle and straight lines, it nonetheless applies a number of unusual design decisions, such as a delicately low x-height (although larger in the bold weight), a tilted 'e' and irregularly angled terminals, to add delicacy and an irregularity suggesting stylish calligraphy, of which Koch was an expert. A variety of rereleases and digitisations have been created.
