A compact sans with a squared, superelliptical skeleton: rounds read as rounded rectangles, with straight-sided bowls and softly radiused corners. Strokes are consistently even and the spacing is tight, creating a dense, efficient rhythm in text. Curves terminate with crisp, squared ends rather than flared or calligraphic finishes, and many forms favor closed or semi-closed apertures (notably in letters like e, a, and s). Numerals and capitals follow the same boxy-rounded construction, producing a cohesive, modular feel across the set.
Well-suited for interface text, navigation systems, wayfinding, and other contexts that benefit from compact, orderly letterforms. It also works for brand systems and packaging where a contemporary, structured sans is desired, and for headlines that can leverage its distinctive rounded-rect geometry.
The overall tone is modern and functional, with a slightly industrial, signage-like clarity. Its rounded-rectangle geometry adds a friendly softness without becoming playful, keeping the voice neutral and matter-of-fact.
The font appears designed to deliver a contemporary sans voice with a distinctive superelliptical geometry, prioritizing compact economy, consistent stroke texture, and a clean, system-like coherence across letters and figures.
The design emphasizes verticality and compactness, which can make lines of text feel efficient and space-saving. The superelliptical construction is consistent across curves, giving the face a distinctive “rounded-square” character compared with more purely circular geometrics.
