A clean geometric sans with round, near-circular bowls and consistent stroke thickness. The lowercase shows a tall x-height and compact ascenders/descenders, keeping lines dense and highly readable. Terminals are mostly straight-cut and crisp rather than fully rounded, while counters stay open and generous (notably in forms like e, a, and s). Overall spacing appears even with a steady rhythm, and the numerals are simple, clear, and aligned in a contemporary, utilitarian style.
It performs well in interface typography and product UI where clarity at smaller sizes benefits from the tall x-height and open counters. The clean geometry also suits brand systems, headings, and short editorial passages, and it should hold up well in wayfinding and signage where quick recognition matters.
The overall tone is modern and approachable, pairing geometric precision with soft, rounded forms. It feels calm and trustworthy rather than edgy, making it suitable for contemporary digital environments while still reading as friendly.
The design appears intended as a versatile, modern workhorse sans: geometric enough to feel contemporary and systematic, but drawn with enough openness and roundness to stay friendly in continuous reading and on screens.
Round letters like C, G, O, and Q lean strongly circular, giving the face a cohesive geometric backbone. Diagonals in V/W/X/Y are clean and straightforward, and the lowercase a and g read as single-storey forms that reinforce an informal, contemporary voice.
