A compact slab-serif design with sturdy, mostly uniform stroke weight and bracketed, blocky serifs. Proportions are relatively narrow with a tight, economical rhythm, and curves (C, O, S) are clean and restrained rather than overly rounded. Terminals are squared and consistent, with clear differentiation between straight stems and curved joins. Numerals follow the same pragmatic construction, making the set feel cohesive and deliberate in text.
Well suited for editorial layouts, book or long-form reading, and document-style typography where a compact serif can add structure without feeling ornate. It can also work in interfaces or data-heavy settings that benefit from clear letterforms and a steady rhythm, as well as headings when a typewriter-inflected voice is desired.
The overall tone is practical and no-nonsense, with a distinct typewriter and office-document flavor. Its compact stance and firm serifs create an editorial, archival feel that reads as dependable and slightly retro rather than luxurious or expressive.
The design appears intended to deliver a robust, space-efficient slab-serif voice with typewriter-like discipline—prioritizing clarity, consistent texture, and a straightforward, utilitarian presence in running text.
Counters stay fairly open at text sizes, and the slab treatment adds texture without heavy contrast. The punctuation and spacing shown in the sample create a steady, even gray value suited to continuous reading while still retaining a mechanical character.
