A clean, geometric sans with monoline strokes and generously rounded curves. Bowls and counters are largely circular, with open apertures that keep letters airy and legible. Terminals are plain and crisp, and joins stay smooth without decorative breaks, producing an even, steady texture in text. Uppercase proportions feel balanced and slightly wide in the round letters, while the lowercase maintains simple, uncluttered construction with clear differentiation between similar shapes.
Well suited for interface typography, product and documentation systems, and general-purpose print or digital layouts where clarity is key. The open shapes and even rhythm also make it a strong option for signage, dashboards, and presentation graphics that need clean, quick reading.
The overall tone is modern and neutral, with a friendly clarity that reads as contemporary and functional rather than expressive. Its geometric regularity gives it a technical, structured feel, while the open forms prevent it from seeming rigid.
The design appears intended as a versatile, contemporary sans that emphasizes geometric consistency and everyday legibility. It aims to provide a dependable voice for systems-oriented design while remaining approachable in longer passages.
Digits follow the same geometric logic as the letters, using rounded forms and consistent stroke behavior for a cohesive set. In paragraph settings the spacing and straightforward shapes create a calm rhythm that stays readable at size without drawing attention to individual letter quirks.
