About
Noto Serif Lao provides Lao-script typography with the consistency and quality needed for publishing, web, and official documentation. The Lao script shares structural similarities with Thai but has its own distinct letterform conventions, which this typeface respects throughout its design. Integration with Latin and Latin Extended characters supports bilingual Lao–English typesetting.
Classification
Brings serif typographic structure to the Lao script, balancing the script's characteristically curved, closed letterforms with modulated stroke contrast drawn from traditional Lao manuscript conventions. A full nine-weight range supports diverse typographic applications.
