Tonos is a sans serif font family designed for UI and HMI contexts, supporting Arabic, Cyrillic, Greek, Hebrew, Latin, and Thai scripts. Its calligraphic heritage gives it a warm, humanistic quality carried across all scripts for harmony and legibility. Available in weights from Light to Bold with matching italics, two widths, and monospaced styles, Tonos also comes as a variable font with weight and width axes, offering versatility for functional yet engaging interface typography.
