Thuluth — meaning "one-third," a reference to the slant ratio of its strokes — is the most ornamental of the classical Arabic scripts. Historically reserved for titles, chapter headings, and monumental inscriptions rather than everyday writing, its tall ascenders and interlocking curves reward slow, deliberate reading rather than quick scanning.
Thuluth is part of the classical "six pens" system formalized in the 10th century alongside Naskh, and it remains the go-to style whenever a design needs to feel formal, ceremonial, or prestigious. Below are 4 Thuluth-style fonts — Katibeh (a Google Fonts family under the SIL Open Font License) alongside A Thuluth, Thuluth Alsmt7017, and ArbFonts Diwany Thuluth (self-hosted freeware sourced outside Google Fonts).
