Variable and optional features of 'Saysettha Mai' Lao font can only be seen when using a browser that supports those features, such as a current version of Google Chrome, Opera, Mozilla Firefox or Microsoft Edge.

Saysettha Mai is a new font-family from Lao Script for Windows in a modern style with straight strokes as often found in primers and other recently printed materials. The font includes the full Unicode range for Lao with both Kmhmu and Lao Pali characters and is available as a single font, a TrueType Collection (.ttc) or a zip-archive with six stroke weights from Thin to Black in both Plain and Italic styles. For publishing purposes, it is also available as a zip-archive of 72 separate fonts in plan and italic styles from Thin to Black weight, UltraCondensed (half regular width) to UltraExpanded (twice regular width).

Note that Microsoft Word does not provide any way to apply Stylistic Set features to Lao text. For a free alternative that handles Lao text correctly in Word documents, download and install LibreOffice Writer.

For web use, and by apps such as Adobe InDesign that support variable TrueType fonts, a 3-axis variable TrueType version of SaysetthaMai (as used on this page) is available in .ttf and .woff2 formats. The variable font may be installed on Windows or macOS but as neither Windows nor macOS manage diacritic positioning correctly for variable fonts, it is usually better to install and use the separate SaysetthaMai font styles and use a non-installed copy of the variable font where supported by the app (e.g. Illustrator, InDesign).

(See also Saysettha and SengBuhan for details and examples of more new fonts.)
