What BoonJot is

BoonJot (บุญจด) is an open-source Thai and Latin handwriting family by Sungsit Sawaiwan, released through FontUni under the SIL Open Font License 1.1 with two styles, Regular and Italic. Its premise is unusual enough to be worth stating plainly: the designer set out to build a handwriting face that reproduces how a left-handed writer forms letters, and drew the whole thing on a computer rather than digitising scanned penmanship.

That origin explains the shapes. Each glyph began as a single stroke sketched in FontForge, was expanded to its proper weight there, then finished in Inkscape. The result is closer to a synthetic hand than a traced one — even, controlled, and free of the ink pooling that scanned handwriting fonts inherit.

BoonJot is not in the Google Fonts registry, which is why it rarely appears in the roundups that only crawl Google’s catalogue. The licence is the same OFL 1.1 that covers Google’s Thai families, so it carries the same commercial rights — see the Thai font licensing guide for what that actually permits.

Character design and tone

BoonJot reads as relaxed upright handwriting rather than connected script: the designer applied an italic aesthetic to upright characters instead of joining them, a decision made specifically so the face stays legible at small sizes on screen. That is the trade most handwriting faces refuse to make, and it is why BoonJot survives at UI sizes where a true script collapses.

The stroke is monolinear — the single-stroke drawing method leaves little thick-thin modulation — which keeps colour on the page even. Against the pen-pressure variation of a face like Mali or the brush weight of Sriracha, BoonJot is the flatter, more utilitarian hand.

Tonally it lands somewhere near a comic hand: informal, friendly, unfussy. It is a notes-and-annotations face, not a ceremonial one.

Weights and availability

BoonJot ships as two styles — Regular and Italic — with no weight axis; the italic arrived in the 1.0 release and the file shipping today reports Version 2.0 in its name table. Do not expect a Light or a Bold; this is a two-file family and the designer scoped it that way.

Character coverage is broader than most Thai handwriting fonts. The face covers Adobe Latin-4, most European languages, Vietnamese and Thai — verified in the font’s own cmap, which carries the full basic Latin alphabet, 87 codepoints across the Thai block, and Vietnamese precomposed forms. Download it from the GitHub releases page.

Best use cases

BoonJot suits work that wants a human hand without losing legibility — annotation, informal branding, and mixed Thai/Latin/Vietnamese settings. Strong briefs:

• Annotations, callouts and margin notes in diagrams and slides
• Casual branding, packaging and menus that want warmth over polish
• Multilingual settings that need Thai, Latin and Vietnamese from one file
• Note-taking and educational material where a handwriting face still has to be read at length

Where it does not fit: formal or institutional documents (reach for a looped body face), and any brief wanting calligraphic elegance — that is Plaimanas07’s territory, not BoonJot’s. Pair it with Sarabun or Anuphan for body text and let BoonJot handle the handwritten layer.

Licensing

BoonJot is free for commercial use: it is licensed under the SIL Open Font License 1.1, confirmed both by the GitHub repository’s declared licence and by the copyright string embedded in the font binary itself. Use, modification, embedding and redistribution are permitted; derivative works must stay under the OFL. Browse other verified commercial-safe options in free Thai fonts and handwritten Thai fonts.
