Sans Superellipse Iffi 4 is a very bold, normal width, monoline, upright, normal x-height font visually similar to 'FF World' by FontFont, 'Home Room JNL' by Jeff Levine, 'Stallman' and 'Stallman Round' by Par Défaut, and 'Reload' by Reserves (names referenced only for comparison).

A heavy, geometric sans built from rounded-rectangle and superellipse-like shapes. Strokes are uniform and dense, with tight apertures and squared counters softened by generous corner radii. Curves resolve into flattened bowls and rectangular interior spaces, creating a compact rhythm with sturdy verticals and crisp terminals. Diagonals (as in K, V, W, X, Y) are straight and assertive, while round letters (O, Q, C, G) read as squarish ovals with consistent curvature. Figures are equally robust, with angular 1 and 7 and a compact, enclosed 8.
Best suited for display typography such as headlines, posters, brand marks, packaging panels, and bold UI or product labeling where strong presence and a tech-leaning character are desired. It works particularly well in all caps, short phrases, and large sizes where the distinctive squared-round forms can read clearly.
The overall tone is mechanical and futuristic, reminiscent of digital interfaces, industrial labeling, and arcade-era display typography. Its blunt geometry and softened corners balance toughness with approachability, giving it a confident, utilitarian voice.
The design appears intended to deliver a high-impact, contemporary voice by combining monolithic stroke weight with rounded-square geometry. It prioritizes uniformity, compactness, and a machine-made look to stand out in modern graphic and interface-oriented contexts.
The tight inner spaces and short openings in letters like S, C, and G emphasize a solid, stamped feel and can reduce clarity at very small sizes. The design’s consistent corner treatment and rectangular counters make it especially cohesive in all-caps settings and short, emphatic words.
