Overview
Kabel is a geometric sans-serif typeface that was designed by the German designer Rudolf Koch and released by the Klingspor foundry from 1927 onwards.
Kabel belongs to the "geometric" style of sans-serifs, which was becoming popular in Germany during its 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 that suggests stylish calligraphy of which Koch was an expert. A variety of rereleases and digitisations have been created.
Design
Kabel shows influence from Expressionism as much as from Modernism, and may be considered as a monoline sans-serif companion of Koch's Koch-Antiqua, sharing many of its character shapes and proportions. This is visible in its low x-height and its two-storey 'g' with a large, partly open lower loop, similar to William Morris's Troy Type, and its 'e' with a tilted centre-stroke, similar to early Renaissance typefaces and also seen in Morris's type designs. The termini of vertical and horizontal strokes are cut an angle, often at right angles to stroke direction, suggesting writing with a pen. This gives Kabel the effect of not quite sitting on the baseline and makes for a more animated, less static feeling than Futura. The capitals vary considerably in width and show influence of Roman square capitals, for instance in the wide 'M' and narrow 'E'. The capital 'W' has a four-terminal form. In the book/regular version, the uppercase 'U' has a stem to the right, which is especially noticeable in the light weight. The capital 'Y' forms a continuous stroke with its tail.
Koch marketed Kabel with a specimen showing the capitals supposedly derived from a construction grid of perfect rectangles and circles, but Walter Tracy and others have noted that this graphic does not really resemble the letters of the printed type, which were clearly drawn freely rather than by uncorrected geometry: "Koch probably drew [his] letters without constraint, and then 'rationalised' them afterwards…Koch was evidently not a man to be bound by arbitrary rules. In Kabel Light the arms of E are actually three different lengths, the bowl of R is deeper than that of B, and in P it is deeper still…and Y does not have the vertical stem shown in the diagram.
