Square Unique ExtraBold by Dieter Schumacher

Bold, blocky geometric caps built from hard right angles

Square Unique ExtraBold builds its letters from thick, squared-off segments with small notched cuts, giving it a technical, circuit-board sort of precision. It is bold and geometric without leaning into a full digital or LCD look.

It suits tech and software branding, modern minimal logos, sci-fi interface mockups, and any design that wants a clean, blocky, engineered feel. Free to download for personal use.
