A compact slab-serif with sturdy, mostly monoline strokes and strongly defined, square-ended serifs. The letterforms are narrow with tight internal counters and a disciplined, vertical rhythm; curves are controlled and slightly squared off, especially in bowls and terminals. Serifs read as bold and supportive rather than delicate, giving the design a firm baseline and consistent texture in paragraphs. The lowercase shows straightforward construction with a modest x-height and clear differentiation between rounded and straight elements, while numerals are upright and pragmatic with even color.
Well suited to editorial layouts, book or report typography, and technical documentation where a firm, consistent texture is desired. It can also serve in compact headlines and captions when a sturdy slab-serif voice is needed without high-contrast refinement.
The overall tone is practical and workmanlike, evoking typewritten and industrial editorial typography. Its strong serifs and compact proportions lend a serious, institutional voice that feels archival and matter-of-fact rather than decorative.
Likely designed to deliver a dependable slab-serif texture in space-conscious settings, balancing typewriter-like sturdiness with enough regularity for continuous reading. The emphasis appears to be on clarity, economy of width, and a stable, authoritative presence.
In text, the face produces a dense, steady gray with pronounced serifs that help guide the eye along the line. The compact width and tight apertures make it feel space-efficient, while the squared terminals and low contrast keep the texture consistent at display and reading sizes.
