Round shapes carry this one. Bowls sit close to true circles, stems hold an even weight, and terminals cut clean and horizontal, which keeps the alphabet quiet even when the letters get big. Arcon is the geometric sans-serif behind that look, drawn by Zarthwork and released through the foundry martin zarth, visuelle & digitale kommunikation. Nothing here is fussy: the construction stays consistent from caps to lowercase, so tight headline tracking never breaks the rhythm.

Two files ship with the family, a Regular plus a companion style, which gives you enough separation to set a headline against a deck without reaching for a second typeface. Latin coverage runs past 277 languages, so multilingual layouts are not an afterthought. It handles display and text duty alike, and the range shows up in practice: strong across architecture and interiors portfolio spreads, comfortable on conference badges and session signage, clean under a SaaS pricing page headline, and steady enough to hold body copy in a short brand guidelines PDF. Numerals keep their geometry too, which helps on spec sheets and price tables where figures need to line up and stay legible at small sizes.

For contrast, put a low-contrast text serif underneath it for long reading passages and let Arcon take headings, captions and figures. A condensed grotesque also pairs well when column space gets tight. Arcon is free under the Open Font License for personal and commercial use, and the files download directly from this page.
