A monoline sans with geometric construction and gently rounded terminals. Curves are drawn with smooth, near-circular bowls and open apertures, while straight strokes stay crisp and consistent in thickness. Uppercase forms feel roomy and balanced, with simple diagonals (A, V, W, Y) and largely symmetrical construction; the G includes a straightforward horizontal bar. Lowercase is similarly restrained and readable, using a single-storey a and g, a compact shoulder on r, and a clean, minimal t with a short crossbar. Figures are simple and evenly weighted, with round 0 and a clearly drawn 4, 7, and 9, maintaining the same calm stroke rhythm as the letters.
Well-suited to interface copy, web typography, and product design where a clean, dependable sans is needed. Its open counters and even stroke rhythm also make it a good option for short brand statements, wayfinding, and general-purpose print layouts.
The overall tone is modern and approachable, prioritizing clarity over personality-driven quirks. Its rounded geometry and open shapes give it a friendly, contemporary feel that stays neutral enough for broad UI and editorial use.
The design appears intended as a versatile, contemporary workhorse: geometric enough to feel modern, but softened with rounded terminals and open shapes to remain comfortable in continuous reading.
Spacing and proportions appear carefully regularized, producing a steady texture in paragraph settings. The design avoids sharp joins and decorative details, leaning on consistent curvature and straightforward forms for a cohesive, system-like appearance.
