Walter Kaech: Rhythm and Proportion in Lettering

Walter Käch’s “Rhythm and Proportion in Lettering” is a short bilingual German/English essay that argues letterforms should be understood as the result of rhythmic movement rather than geometric construction.

Instead of treating letters as shapes built with compass and ruler, Käch frames them as traces of a tool moving through space, where proportion emerges from stroke flow, contrast, and spacing, drawing on historical examples like Roman capitals and critiquing Renaissance geometric methods as artificial, and supporting his argument with drawn alphabets and proportional analyses (including references to natural proportion and the golden ratio), making the book less a manual or system and more a didactic, almost polemical attempt to re-ground typography in calligraphic logic.
