Zilla Slab

Zilla Slab is a contemporary slab serif with sturdy, even stroke widths and rounded terminals that give it a friendly but grounded appearance. It was developed by Mozilla and carries a distinctly modern engineering sensibility, avoiding the fussiness of traditional serifs while retaining the structure and authority that the slab category is known for. Its letterforms are clean and geometric without being cold, making it readable at a range of sizes and adaptable across digital and print contexts. The overall tone is confident and approachable, sitting comfortably between editorial seriousness and accessible warmth.

Because of its strong x-height and clear legibility, Zilla Slab works well as a display or heading typeface for tech companies, independent publications, and nonprofits that want a professional look without feeling corporate or stiff. It performs particularly well in editorial layouts where the headings need to carry visual weight and establish hierarchy without competing with body text. It also suits branding contexts for startups or mission-driven organizations that want to signal reliability and clarity, and it holds up in UI settings for marketing pages where primary headlines and call-to-action text need to read quickly and memorably.
