What Srisakdi is

Srisakdi is a handwritten Thai display face modelled on early Rattanakosin-period penmanship, published on Google Fonts by Cadson Demak in 2018 in two weights under the SIL Open Font License. It is the Google Fonts revision of TH Srisakdi, one of Thailand’s 13 National Fonts.

The lineage is documented in the project repository. Prof. Srisakdi Charmonman produced the original design; the drawing was commissioned to Akarameytee — Pairoj Peamjakapong — and Bavorn Joradol, who finished it for SIPA Thailand’s National Fonts project. The font carries the professor’s name (ศรีศักดิ์). On 7 September 2010 the Thai cabinet adopted the 13 National Fonts as the official public fonts for government agencies. In 2018 Cadson Demak reworked the whole set with Google Fonts, and Srisakdi entered the library in that batch, on 22 August 2018.

Few free fonts arrive with this much paperwork: a named professor, a 2010 cabinet resolution, and a foundry revision eight years later.

Character design and tone

Srisakdi imitates what Cadson Demak calls “controlled handwriting using western ink and paper” from the early Rattanakosin era — a 19th-century clerk’s hand, regularised into a typeface. The letterforms keep the slant and flicked tail of period manuscript writing, which gives every line a documentary, old-world cast.

The foundry’s own framing is generous: the repository describes Srisakdi as “an ideal of old style long reading Thai text face for retrospective occasions.” In practice the claim deserves a caveat. Google Fonts categorises the family as display, it ships only two weights, and the handwriting detail that charms at 40px clots at 14px. Treat Srisakdi as a headline and titling instrument; for paragraph-length retrospective text, its upright spin-off Thasadith was built for exactly that typesetting job.

The Latin is styled to match the Thai manuscript flavour, so bilingual title cards stay in period.

Weights and availability

Srisakdi ships two weights — Regular (400) and Bold (700) — in upright cuts only, with Latin, Latin Extended, Thai, and Vietnamese subsets. No italics, no intermediate weights.

Two weights is the smallest family in Cadson Demak’s National Fonts revision, and it constrains hierarchy: there is no Light for oversized title settings and no Medium between the two cuts. The earlier TH Srisakdi remains available through the original National Fonts distribution for documents that must match government templates.

How to download Srisakdi

Srisakdi is a free download from Google Fonts — the family ZIP contains both TTF weights, no registration required. Three routes:

1. Google Fonts ZIP — open the Srisakdi specimen, click “Get font”, and download the family.
2. CSS embed — load https://fonts.googleapis.com/css2?family=Srisakdi:wght@400;700&display=swap in a <link> tag, then set font-family: 'Srisakdi', serif;. Reserve it for headings in the stylesheet; body text is not its job.
3. GitHub source — the cadsondemak/Srisakdi repository holds the font files and project documentation.

Best use cases

Srisakdi belongs on anything that needs to read as a Thai historical document: exhibition titles, ceremony print, and retrospective editorial covers. Strong briefs:

• Museum and heritage exhibition titling, especially Rattanakosin-era subject matter
• Certificates, invitations, and ceremonial print
• Period film and book title treatments
• Restaurant and spirits branding trading on pre-modern Thai identity

Where it fails: interface text and body copy at screen sizes, corporate identity of any contemporary kind, and data-heavy layouts. It is a costume, and costumes do not belong in spreadsheets. For the same voice at text sizes, use Thasadith; for a looser script feel, Sriracha or Charm.

Pairings

Srisakdi sets the headline; everything else on the page should stand back. Three pairings:

• Thasadith — the natural partner: an upright sans spun off from this same family, for body text under Srisakdi titles
• Maitree — looped serif body when the page should stay antique throughout
• Sarabun — neutral body that lets the display face do all the talking

Display-plus-text system guidance is in the typography guide.

Licensing

Srisakdi is released under the SIL Open Font License — free for commercial use, web embedding, modification, and bundling, provided the OFL notice stays with the files. The copyright line reads “Copyright 2018 The Srisakdi Project Authors.” Verify at the Google Fonts specimen or the GitHub repository. The original TH Srisakdi was likewise distributed free under the National Fonts project, so neither generation of the design has ever cost anything.
