Kabel is a geometric sans-serif typeface designed by German typeface designer Rudolf Koch, and released by the Klingspor foundry in 1927. The face was named to honor the newly completed trans-Atlantic telephone cable. Today the typeface is licensed by the Elsner+Flake GbR foundry.

Like its contemporary Futura it bears influence of two earlier geometric sans-serif typefaces; the 1919 Feder Schrift, drawn by Jakob Erbar, and more so his 1922 design called Erbar. Still, Kabel comes less out of the influences of German modernism, but more German expressionism. Stroke weights are more varied than most geometric sans-serifs, and the terminus of vertical strokes are cut to a near eight-degree angle. This has the effect of not quite sitting on the baseline and making for a more animated, less static feeling than Futura. Uppercase characters are broad and show influence of monumental roman capitals. The capital W is splayed and the G has no terminal. Lowercase characters a, e, and g show a link with Carolingian script.
