A compact, heavy text-and-display face built from squared, superelliptical curves with softly rounded corners. Strokes are robust and fairly even, with subtle contrast that shows most clearly where curves meet straights. Counters tend to be tight and oval-to-rectangular, and many joins feel engineered and crisp, giving the letters a tall, condensed rhythm. Lowercase forms stay straightforward and vertical, with a single-storey a and a double-storey g, plus sturdy stems and short, efficient terminals.
Best suited to headlines, subheads, and short bursts of copy where a compact, high-impact voice is needed. It works well for posters, signage, packaging, and brand wordmarks that want a sturdy, engineered presence, and it can serve as a strong secondary typeface for emphasis within editorial layouts.
The overall tone is forceful and matter-of-fact, combining a contemporary, industrial clarity with a slightly retro newspaper-headline punch. Its compact width and dense color make it feel urgent and emphatic, while the rounded-square construction keeps it from becoming harsh.
The design appears intended to deliver maximum impact in limited horizontal space, using rounded-rectangle geometry to create a consistent, modern silhouette. Its restrained detailing and dense texture suggest a focus on clarity and authority in display settings rather than delicate, extended reading.
At text sizes the tight spacing and small internal counters can make the darkest letters (notably m, n, w, and dense uppercase forms) read as solid blocks, so it benefits from generous tracking and line spacing. The numerals follow the same tall, condensed construction, with strong verticals and simplified shapes suited to bold callouts.
