Preview TH Sarabun PSK
TH Sarabun PSK is a foundry/desktop font, so it can’t be embedded as a free webfont for a live preview here. See the specimen above for the real letterforms, or load your own text into the Thai Font Tester to compare it against the free Google Fonts alternatives.
What TH Sarabun PSK is
TH Sarabun PSK is the original looped humanist sans that became Thailand’s official government-document typeface: one of the 13 National Fonts (ฟอนต์แห่งชาติ) that the Council of Ministers designated in 2010, designed by Suppakit Chalermlarp and distributed free through f0nt.com. It is the file that agencies first installed to comply with the National Font mandate, and the direct predecessor of TH Sarabun New.
The name matters because two different files share the “Sarabun” label and Thai office workers mix them up constantly. TH Sarabun PSK is the 2007-era original from the SIPA National Font set. It works, but it shipped with rendering defects — spacing and diacritic bugs that surfaced in newer versions of Microsoft Office. Suppakit Chalermlarp revised it into TH Sarabun New in 2011, and that revision is now the file most templates expect.
For anyone auditing an old document, a legacy government template, or a decade-old thesis file, TH Sarabun PSK is still the typeface embedded in it. Understanding the PSK-versus-New distinction is the whole reason this page exists — see /learn/typography/ for how Thai document conventions evolved.
Character design and tone
TH Sarabun PSK is a looped (มีหัว) near-monolinear sans: clear circular consonant heads, open counters, and a plain, bureaucratic neutrality built for laser printing and photocopying. The loops on ก, ถ and ภ stay open at the 14–16pt sizes where Thai official documents set their body text.
Against Angsana New, the Windows-bundled serif it displaced as the de facto standard, TH Sarabun PSK drops the stroke contrast and dated terminal detailing. The result reads cleaner at the same size and photocopies without the loops filling in. The typeface expresses nothing — which, for a memo, a form, or a gazette page, is precisely the job.
The Latin companion is a plain humanist sans sized to sit evenly with the Thai, so bilingual official documents — visa forms, transcripts, ministry letterheads — hold a consistent texture across both scripts.
Weights and availability
TH Sarabun PSK ships four cuts — Regular, Italic, Bold and Bold Italic — the standard National Font loadout, distributed as TrueType through f0nt.com. There is no light, medium or display weight; the National Fonts were document faces, not branding systems.
The font is not on Google Fonts. The eight-weight family called Sarabun on Google Fonts is a separate, later OFL release in the same design lineage — not the same file and not the same licence. If you need to match a government template byte for byte, the PSK (or its successor New) TrueType file is the one to install.
TH Sarabun PSK vs TH Sarabun New
Install TH Sarabun New for any document you are creating today; keep TH Sarabun PSK only to open or match legacy files that already use it. TH Sarabun New corrected the rendering defects in PSK — including Thai-language problems in Microsoft Office — and is the version Thai users searching “th sarabun ดาวน์โหลด” actually want.
Both live in the same free National Font distribution. The practical rule: New for new work, PSK for backward compatibility. The web equivalent for either is Sarabun on Google Fonts.
Best use cases
TH Sarabun PSK belongs to legacy and compatibility work rather than new documents. Concrete briefs:
- Opening and editing older government files that already embed TH Sarabun PSK
- Matching decade-old ministry templates, tender documents and archived theses
- Auditing which Sarabun variant a legacy PDF or Word file was set in
- Any workflow that specifies “TH Sarabun PSK” by name and must not be silently upgraded
Where it does not fit: brand-new official documents (use TH Sarabun New), web projects (use Sarabun), and branding or display work, which two document weights cannot carry.
Licensing
TH Sarabun PSK is free to use: SIPA and the Department of Intellectual Property released the 13 National Fonts royalty-free for public and official use. Verify the distribution on the f0nt.com National Fonts page; the successor release adds a formal GPL-with-font-exception note on the TH Sarabun New page. Commercial use, redistribution and embedding in PDFs and Word files are permitted. For a plain-language walk-through of Thai font licences, see /learn/typography/thai-font-licensing/.
