What Anuphan is

Anuphan is a loopless Thai sans-serif from Cadson Demak, drawn as an independent Thai counterpart to IBM Plex. It ships seven weights in a single variable font, free on Google Fonts under the SIL Open Font License. Its Thai name is อนุพันธ์, as catalogued by ThaiFaces.

The project has an unusually candid origin note. The description shipped with the font on Google Fonts states it was intended for self-improvement and educational purposes — a designer’s study exercise that ended up in production distribution. Critically, Anuphan is not a modification of IBM Plex Thai. Per the project documentation, every Thai outline was drawn from the Latin version of IBM Plex Sans, working out what Plex’s engineered Latin logic would look like if a Thai script had been built from it directly.

The designer credit takes two forms depending on the source: the Google Fonts description names Mint Tantisuwanna, a type designer at Cadson Demak, while ThaiFaces records the Thai name กรกนก ตันติสุวรรณนา and dates the entry 18 December 2019. Google Fonts added Anuphan to its catalogue on 23 February 2023, per the METADATA.pb entry.

Anuphan’s weights — SemiBold exists, ExtraBold does not

Anuphan covers seven weights, Thin (100) through Bold (700). Anuphan SemiBold is weight 600 and is a real cut; Anuphan ExtraBold (800) and Black (900) do not exist, because the variable weight axis stops at 700. Confirmed by the METADATA.pb file in the google/fonts repository, which declares the wght axis range as 100–700.

The 700 ceiling is worth knowing before you start. Families like Noto Sans Thai and Kanit run to Black (900); Anuphan stops at Bold, so there is no heavyweight cut for posters or packaging, and no italic either. If a design tool offers “Anuphan ExtraBold”, that is faux bold generated by thickening outlines — and on Thai it crowds the space around vowel signs and tone marks until legibility suffers.

The upside of the variable build is intermediate weights: font-variation-settings: 'wght' 550; gives you a step between Medium and SemiBold without loading another file.

Where to download Anuphan free

Anuphan is a free download from Google Fonts: take the family ZIP with all seven static weights, or the single variable file covering the full 100–700 range. No registration, no payment.

1. Google Fonts ZIP — open the Anuphan specimen, click “Get font”, and download the family ZIP.
2. CSS embed — load https://fonts.googleapis.com/css2?family=Anuphan:[email protected]&display=swap in a <link> tag, then set font-family: 'Anuphan', sans-serif;.
3. GitHub source — the cadsondemak/Anuphan repository holds the source files under OFL-1.1 for self-hosting or modification.

Is Anuphan free for commercial use?

Yes. Anuphan is released under the SIL Open Font License, which permits use, embedding, modification and redistribution at no cost, commercial work included. Self-hosting the variable file in a commercial product requires no permission and no fee.

That covers client work, product interfaces, packaging, signage, webfonts and app embedding. What it excludes: selling the font files on their own, and applying the original Reserved Font Name to a modified version. See our Thai font licensing guide for the practical detail.

Character design and tone

Anuphan reads as engineered rather than expressive: loopless heads, low stroke contrast, and squared joins carried over from the IBM Plex Sans Latin it was drawn from. Consonants that traditionally carry a circular head — ม, บ, ภ — open into simplified hooks instead.

The result is closer to a Latin grotesque wearing Thai proportions than to a humanist Thai sans. Curves are tense, counters are open, and the vertical rhythm is even enough that mixed Thai-English paragraphs hold a single texture. That bilingual evenness is the design’s whole argument. Where Kanit brings geometric personality and Noto Sans Thai brings deliberate neutrality, Anuphan brings Plex’s drafting-table character: technical, slightly cool, consistent at small sizes.

The trade-off is warmth. Anuphan has little of it, and projects that want a friendly consumer tone will find it stiff — Prompt is the better fit there.

Anuphan versus IBM Plex Thai

Both sit in the Plex orbit, but IBM Plex Thai is the Thai script developed officially within the IBM Plex system, while Anuphan is an independent redraw of Thai from Plex’s Latin, not a modification of the existing Thai files. The difference is provenance, not just appearance.

• Choose IBM Plex Thai when your design system is formally tied to IBM Plex
• Choose Anuphan when you want a technical loopless Thai plus the convenience of one variable file
• Choose Noto Sans Thai when you need neutrality and weights up to Black

Best use cases

Anuphan fits product interfaces, developer documentation, and bilingual corporate sites where Thai text must match the discipline of IBM Plex or a similar engineered Latin. Strong briefs:

• Dashboards and admin interfaces with mixed Thai-English labels
• Technical documentation and API references for Thai-market software
• Fintech and enterprise products already standardised on IBM Plex
• Data-dense layouts where the variable weight axis earns its keep

Where it fails: anything that needs an italic (there is none), display work above Bold weight, and formal print contexts that still expect looped letterforms — Sarabun or another looped face belongs there instead.

Pairings

Anuphan pairs most naturally inside the Plex orbit, with a Thai serif added for editorial contrast. Three combinations:

• IBM Plex Thai — the obvious sibling for full bilingual design systems
• Noto Serif Thai — headline serif over Anuphan body for report and editorial layouts
• Sarabun — a softer looped alternate body when Anuphan runs too cool

The Thai typography guide covers loopless pairing logic in detail, and the full Thai font library has the rest of the field.

Licensing

Anuphan is released under the SIL Open Font License: free for commercial use, modification, embedding, and bundling, provided the OFL notice stays with the files. Verify at the Google Fonts specimen or the GitHub repository, which states OFL-1.1.
