A wide, light slab-serif with crisp, square-ended serifs and largely uniform stroke weight. The letterforms favor open counters and generous sidebearings, producing an airy rhythm and a strong horizontal emphasis. Curves are clean and controlled, while terminals and joins stay rectilinear, giving the design a tidy, engineered feel. Numerals and capitals read evenly at display sizes, with clear silhouettes and minimal contrast-driven modulation.
Best suited to headlines, subheads, and short paragraphs where its wide proportions and slab structure can set a clear, authoritative tone. It works well for editorial layouts, book and magazine titling, posters, and branding that wants a measured, classic voice with strong, square serifs.
The overall tone is composed and literary, suggesting textbook, editorial, or institutional typography rather than expressive display. Its wide stance and sharp slabs add a faint mid‑century or typewriter-adjacent nostalgia, while still feeling orderly and contemporary. The result is confident and calm, with a slightly formal voice.
The design appears intended to deliver a clean slab-serif presence with broad proportions and restrained detailing, prioritizing clarity and an even reading texture. Its geometry and square serifs suggest an aim for a dependable, structured look that stands out through width and spacing rather than heavy weight or high contrast.
The font’s spacing and broad proportions make it most comfortable when given room, and the crisp slabs remain a defining feature even in smaller words. The lowercase forms appear straightforward and readable, with simple, uncluttered construction that keeps texture consistent across lines.
