TikTok Sans is the brand and product's custom font, created in 2022 by Grilli Type. It has since been expanded for all Roman languages, and to further strengthen global consistency, we expanded into the Arabic, Urdu, Kurdish, and Farsi languages. The new font family, TikTok Sans Arabic, will be implimented across the brand as well as product UI.

Led design direction, creative decisions, and oversight of the agency partner, Morcos Key, throughout the development of the typeface and brand typography guidelines, as well as coordinating feedback across several cross-functional teams.
