A clean sans with a geometric backbone and generously rounded curves. Strokes are even and steady, with smooth joins and unadorned terminals that keep the texture consistent in both display and text. Round letters (O, C, G) read as near-circular, while straight-sided forms (H, N, E) stay crisp and orthogonal; proportions feel balanced rather than condensed or extended. Counters are open and the lowercase is straightforward, producing a calm, regular rhythm across words and lines.
Works well for interface copy, documentation, and general-purpose editorial text where neutrality and legibility are priorities. Its clean geometry also suits presentations, brand systems, and product graphics, and it can scale up for straightforward signage and headings without becoming brittle.
The overall tone is contemporary and unobtrusive, projecting clarity and approachability rather than personality-driven flair. Its restrained shapes and predictable spacing give it a professional, utilitarian voice that stays out of the way of content.
The design appears intended as a dependable, modern sans for everyday reading and communication—prioritizing clarity, consistent rhythm, and broad usability over decorative detail.
Numerals are simple and highly legible, matching the letterforms in stroke weight and curvature for a cohesive typographic color. The sample paragraph shows stable word shapes and consistent spacing, with rounded forms preventing the texture from feeling rigid or technical.
