What TH Chakra Petch is
TH Chakra Petch is the original SIPA National Font of that name — a modern loopless Thai face in four styles, designed by Thirawat Photwibunsiri and released free in 2007 by SIPA and the Department of Intellectual Property. Named “diamond wheel” (จักรเพชร), it carries the “TH” prefix of the government’s royalty-free set, and it is a separate file from the later Google Fonts family of the same name.
Chakra Petch is one of the National Font family’s contemporary faces. Built on a squared, geometric logic, it strips the loops from the Thai skeleton to produce a clean, modern (ตัวไม่มีหัว) look — a deliberate step away from the traditional looped document faces around it in the set.
The name is now shared by two things, and the distinction is the reason to read this page. The Google Fonts Chakra Petch is a later, OFL multi-weight family. The TH Chakra Petch documented here is the SIPA original, four styles, distributed free inside the National Font package — see /learn/typography/ for how loopless construction reshapes a Thai face.
Character design and tone
TH Chakra Petch is a loopless Thai face with a squared, geometric build: the traditional loops are opened out into clean strokes, giving the letters a modern, slightly technical silhouette. Details that a document face would keep are pared back, which is what makes the face read as contemporary rather than formal.
The strokes are even and the terminals disciplined. Set as headings the geometric structure reads with confidence; the loopless heads keep the face looking current next to the looped members of the National Font family. Latin support sits alongside the full Thai character set.
The tone is modern and structured — a designed, forward-looking Thai face rather than a neutral office default. It signals contemporary intent, which is exactly the register a loopless construction lends.
Weights and availability
TH Chakra Petch ships four cuts — Regular, Italic, Bold and Bold Italic — the standard National Font loadout, distributed as TrueType through f0nt.com. Download it from the f0nt.com National Fonts package, the single channel SIPA used for all thirteen originals.
If you need the multi-weight webfont version, that is the separate Google Fonts Chakra Petch family — different file, OFL licence, wider weight range and proper web packaging.
Best use cases
TH Chakra Petch suits modern, structured layouts that want a loopless Thai face from the free National Font set. Strong briefs:
- Headings, titles and signage with a contemporary, geometric feel
- Technology, gaming and youth-facing design that wants a loopless look
- Posters and display work needing a modern Thai voice
- Bilingual Thai-English layouts with a clean, squared texture
Where it does not fit: strict official correspondence, which expects Sarabun or TH Sarabun New, and long-form body reading, where a looped humanist face is easier on the eye.
