Playpen Sans was designed by TypeTogether after over two years of primary research into handwriting education for Latin-based languages, available at primarium.info.

It is a variable font with a weight range from Thin (100) to ExtraBold (800) and supports three different writing systems—Latin, Greek, and Cyrillic—that cover over 700 Latin languages, including Vietnamese and 619 Sub-Saharan African languages, 54 Cyrillic languages, and Greek, along with 26 emoji. The Playpen Sans superfamily also includes an Arabic (Playpen Sans Arabic), Devanagari (Playpen Sans Deva), Hebrew (Playpen Sans Hebrew), and Thai (Playpen Sans Thai) fonts that expand the language support of the system.

Playpen Sans provides seven different glyphs for each character that are automatically applied as you type, using a built-in shuffler that both ensures variety and avoids repetition. This adds to the overall organic, spontaneous, and authentic feel of the handwritten style.
