A tightly condensed display sans with tall proportions and compact internal spaces. Strokes are largely monolinear in feel with modest contrast, and terminals are clean and blunt, producing solid, rectangular silhouettes. Round characters read as rounded-rectangle forms rather than perfect circles, giving counters a squared, superelliptical character. The lowercase is small relative to the capitals, with short ascenders and descenders and a dense texture at text sizes; numerals follow the same narrow, sturdy construction for a consistent, space-efficient rhythm.
Best suited for headlines, titles, and short blocks of copy where space is limited and impact is needed—such as posters, signage, packaging, and brand marks. It can also work for compact labels and interface headers when set with ample spacing to keep forms from filling in.
The overall tone is forceful and utilitarian, with a compressed, upright stance that feels direct and attention-seeking. Its compact shapes and squared curves add an industrial, engineered flavor that reads confident rather than friendly, making it well-suited to bold statements.
The design appears intended to deliver maximum presence in minimal horizontal space, combining sturdy verticals with squared-off, rounded forms for a modern, industrial display voice. Its restrained detailing and uniform construction suggest a focus on legibility at large sizes and a consistent, punchy texture.
Because of the narrow widths and tight counters, the face gains punch in larger sizes where its superelliptical curves and strong verticals can be appreciated. In longer passages, the dense color and small lowercase can feel heavy, so generous tracking and line spacing help maintain clarity.
