What ThaiSans Neue is

ThaiSans Neue is a free loopless Thai sans by Letsego, released on f0nt.com on 18 January 2013, in nine weights from UltraLight to Black, each with an italic — 18 styles in all. The official name is written “ThaiSans Neue”, but most people search “Thai Sans Neue”; both mean this font. The release page showed 707,204 downloads on 19 October 2026.

It is Thai Sans Lite redone as a complete family. The designer writes “เคยสัญญาไว้ว่าจะทำตัว Lite ให้สมบูรณ์ พอดีมีเวลาว่าง เลยถือโอกาสทำใหม่ครับ” (“I promised to finish the Lite, had some free time, so I took the chance to redo it”), and says the hard parts were proportions, stroke and stem width in the heavy weights, which forum members helped him resolve. The font files name the copyright holder and designer as Dhanbisishthabongs Kliauklom; Letsego is the f0nt.com name, and the designer page lists three fonts.

The release page carries a PayPal link for anyone who wants to support the designer. Payment is optional.

Every ThaiSans Neue weight, and its name in Word

ThaiSans Neue has nine weights, lightest to heaviest: UltraLight, ExtraLight, Light, Regular, SemiBold, Bold, ExtraBold, UltraBold and Black, each paired with an italic. There is no Medium. That order departs from the standard CSS weight-name table, which MDN gives as Extra Light = Ultra Light = 200 and Extra Bold = Ultra Bold = 800. In this font UltraLight is lighter than ExtraLight and UltraBold heavier than ExtraBold, going by the stem widths ThaiGraph measured in the files.

This table answers the most common problem: everything installed, but no heavy weights in the menu. In Word, Regular, Italic, Bold and Bold Italic sit under the single name “ThaiSans Neue”; every other weight gets its own abbreviated name, such as “ThaiSans Neue SemBd”. Pick that name and press I for its italic.

One more detail: two pairs share a usWeightClass value (UltraLight and ExtraLight at 250, ExtraBold and UltraBold at 800). If you write your own @font-face rules, assign each file a font-weight value that does not collide.

Where to download ThaiSans Neue

Download it from the f0nt.com release page. The zip contains License.pdf, a Files.txt of checksums, and two sets of fonts — an OpenType CFF folder (.otf) and a TrueType folder (.ttf), 18 files each. Install one set only. The release page states that clicking download means accepting the licence.

1. Open the ThaiSans Neue 1.0 page on f0nt.com and click download.
2. Unzip it and read License.pdf first (summarised in the next section).
3. Windows and Office: use the TrueType folder. macOS takes either set. Do not install both .otf and .ttf, or the names will duplicate in your font menu.

The files are version 1.00 from 2012. Files.txt lists CRC-32, MD5 and SHA-1 values for every file, so you can check that what you downloaded has not been altered — a good reason to download from the release page rather than an aggregator.

Is ThaiSans Neue free for commercial use?

Yes. Clause 1.2.1 of the License.pdf in the zip permits producing every kind of promotional media — print, electronic, online and other — for both commercial and non-commercial purposes. That file is the governing agreement, because f0nt.com’s licence says terms the font owner attaches to the font take priority.

The key clauses of License.pdf (Thai original, our summary):

• 1.2.1 — use for producing any media, commercial and non-commercial
• 2.2 — copy more than one set and install on unlimited computers
• 2.1 — no renting out the font or transferring rights under the licence to others without written consent
• 2.3 — no reproducing, modifying, translating, renaming, renumbering, re-encoding or rearranging the font without written consent, unless the law permits
• 2.4 — no removing or obscuring copyright or trademark notices
• 3 — supplied as-is, with no warranty and no liability for any damage

What the licence does not address directly is webfonts and app embedding. Converting to WOFF2 or subsetting could fall under “modify” or “rearrange” in clause 2.3, and putting the file on a server for every browser to download comes close to distribution. For that use, get the designer’s consent first. Alternatives that need no permission are SIL OFL families such as Kanit or Prompt; the Thai font licensing guide explains the differences between licence types.

Why ThaiSans Neue looks small, and what size to set

ThaiSans Neue’s Thai consonant height is 0.430 em against Kanit’s 0.540, so at the same size its Thai looks about a fifth smaller. Body text set in Kanit at 16pt needs ThaiSans Neue at about 20pt to look comparable. ThaiGraph measured the top of น in the Regular file against other fonts’ files from the google/fonts repository.

The right-hand column is the mean width of the consonants ก–ฮ divided by the height of น, which describes the letter proportions independent of point size. Scaled so the Thai is the same height, ThaiSans Neue is noticeably narrower than Kanit and Prompt, but still wider than a true condensed face like ThaiGraph Condensed.

In Word, set the size in the Complex scripts section of the Font dialog, which a Microsoft Q&A answer identifies as the section that controls the Thai font — not the Latin text section.

Using ThaiSans Neue in Word, PowerPoint, Canva and Figma

Install the TrueType folder and it works in Word and PowerPoint straight away, but embedding it in a PowerPoint file only works at Preview & Print level: recipients without the font can open the file read-only. The steps, per Microsoft: right-click the zip, choose Extract, select every file in the TrueType folder, right-click and choose Install.

• Word / PowerPoint — every file has fsType 4, which the OpenType specification defines as embeddable for viewing and printing, with documents opened read-only. If a team edits slides together, everyone should install the font. Embed fonts in the file is under File → Options → Save, per Microsoft.
• Canva — if a search of Canva’s font library does not find it, upload the files to a Brand Kit, available on Pro, Teams, Business, Education and Nonprofits; Canva says fonts “should be licensed for embedding”. ThaiGraph has not test-uploaded this set.
• Figma — ThaiSans Neue is not on Google Fonts (per the catalogue listing), so install it locally and pick it from the “Installed by you” filter, per Figma’s help page.
• Phones — standard iPhone and Android cannot install it as a system font; see installing Thai fonts on a phone.

What ThaiSans Neue is good for

ThaiSans Neue suits work that needs several levels of hierarchy from one loopless Thai family — presentations, posters, advertising and infographics — because it runs from UltraLight to Black with italics throughout. Italics in every weight are not standard among free Thai fonts; on Google Fonts, Kanit and Prompt offer the same (per Kanit’s METADATA file).

Where it does not fit:

• Websites and apps — the licence does not clearly cover webfonts (see the licence section above)
• Long body text — Héctor Mangas’s experiments, published by Typotheque, conclude that “For settings where more texts is presented, looped is preferred for all users”. Use a looped face such as Sarabun for body text instead

ThaiSans Neue or Kanit?

Choose Kanit when the work goes on a website or in an app, or when you want an open licence like the SIL OFL. Choose ThaiSans Neue for print and slides that want narrower Thai proportions, where you will not modify or redistribute the font files. Both have nine weights with italics, and both are loopless.

Pairings

ThaiSans Neue does its best work in headings with its heavy weights, so pair it with a looped face for body text. Two pairings that work:

• Sarabun — ThaiSans Neue Bold or Black headings over Sarabun Regular body text
• Noto Serif Thai — editorial work with a serif body, using ThaiSans Neue Light or Regular for captions and supporting data
