Angsana New (อังสนานิว) has been the default Thai serif of Word documents in Thailand for three decades. If you are here because it vanished after a fresh Windows 11 or Windows 10 install, the first section restores it. Its origins, the AngsanaUPC difference, the licence and the free substitutes follow.

Angsana New missing from Windows 11 or 10? How to restore it, and whether it works on Mac and phones

The font is not gone. Microsoft moved Angsana New out of the default Windows 10 and 11 install into an optional feature called Thai Supplemental Fonts, which you switch back on for free from Settings in five steps, with nothing to download from third-party sites. Mac, iPhone and Android do not have it in the operating system and there is no file to install, but Microsoft 365 subscribers get it inside Word, Excel and PowerPoint on those devices as a cloud font; outside Office, use the free Thai serif in the last subsection.

Restoring it on Windows 11

Steps per Microsoft’s documentation (revised 27 February 2025):

1. Right-click Start → Settings
2. Left pane: System → right pane: Optional features (Shortcut: right-click Start → Run → enter ms-settings:optionalfeatures → OK)
3. Select View features next to Add an optional feature
4. Find and tick Thai Supplemental Fonts
5. Select Next, review, then Add

Microsoft notes that on some Windows 11 builds the Optional features pane sits under Settings → Apps instead. If you cannot find it, the ms-settings:optionalfeatures shortcut opens the same pane on every build.

Restoring it on Windows 10

1. Right-click Start → Settings → System → left pane Optional features
2. Select the + next to Add a feature
3. Tick Thai Supplemental Fonts and select Add

For Windows 10 builds before 22H2, Microsoft’s Windows 10 font list gives the older path: Settings → Apps → Apps & features → Optional features.

The alternative: add Thai as a language and the fonts follow

The Windows 10 font list explains that most script-specific font packages “are added automatically by Windows Update when the associated languages are enabled in language settings (for example, by enabling a keyboard)”. So if you want full Thai language support, go to Settings → Time & language → Language & region (Windows 11) or Time & Language → Language (Windows 10), add Thai under Preferred languages and choose the language features you need during install. The shortcut to that pane is ms-settings:regionlanguage.

Both routes install through Windows Update, so the device must be online. Where an organisation blocks Windows Update, the optional feature will not install and needs either a temporary exception or a Features on Demand deployment.

Mac, iPhone, iPad and Android

Angsana New is not part of the Apple or Android operating systems and Microsoft has never released a file you could install yourself, but Microsoft 365 subscribers can use it inside Word, Excel and PowerPoint on Mac, iOS, Android and the web through Office’s cloud fonts. Apple’s Fonts included with macOS Sonoma lists no Angsana New, AngsanaUPC or any other Microsoft Thai font — the Thai face on Mac and iPhone is Thonburi, and Android uses Noto Sans Thai per the Android system font configuration. A Word file set in Angsana New opened on those devices without Microsoft 365 gets substituted and reflows.

The one legitimate route outside Windows is Office cloud fonts. Microsoft’s Cloud fonts in Office page explains that cloud fonts are hosted in the cloud by Microsoft 365 and available in the latest Office apps on Windows, macOS, web, Android and iOS (availability varies by app); the list includes Angsana New, AngsanaUPC, Cordia New, CordiaUPC, Browallia New and Leelawadee. Picking the font in the menu downloads it, and Microsoft states that documents created with cloud fonts “will render the same when opened in the Office apps listed in the table—without you having to embed them”. The scope is Office apps under a Microsoft 365 subscription only: the font does not appear in Font Book or other apps on the device, and it carries no webfont right. For anything outside Office, share a PDF or start from a free font that installs everywhere.

The free Thai serif that installs everywhere: Noto Serif Thai

If a document must open identically on Windows, Mac, phones and the web, use Noto Serif Thai — a Thai serif in nine weights under the SIL Open Font License, free from Google Fonts. Commercial use, web embedding and sending files to a printer are all covered. To install:

• Windows — right-click the .zip → Extract, then right-click the font files → Install, per Microsoft’s guide
• Mac — double-click the font file in Finder and click Install, per Apple’s Font Book guide
• iPhone / iPad — install through a font-manager app from the App Store and manage under Settings → General → Fonts, per Apple’s guide; usable in document apps
• Web — embed with @font-face or load from Google Fonts directly

If the destination is a Thai government agency, TH Sarabun PSK is the closer fit. All options are compared under “Free Thai serif alternatives to Angsana New” below.

What Angsana New is

Angsana New is the Thai serif Microsoft bundles with Windows and Office. Microsoft’s typography documentation describes it in one line: “a Thai font designed by Unity Progress and offered under license from Microsoft.” The copyright on the same page reads ”© 1992 Unity Progress. Portions © 2004 The Monotype Corporation. Portions © 2015 Microsoft Corporation.”

The family ships in four styles — Angsana New, Angsana New Bold, Angsana New Bold Italic and Angsana New Italic — packaged in a single file, Angsana.ttc (a TrueType Collection). That differs from Cordia New, which ships as four separate .ttf files.

Angsana New is the serif half of the default Thai pair on Windows, with Cordia New as the sans half. Both come from Unity Progress and share the same 1992 copyright year. That is why two decades of Thai contracts, government letters and academic papers look interchangeable — not because anyone chose the typeface, but because it was what the machine had.

Angsana New vs AngsanaUPC

They are two cuts of the same family that Microsoft ships side by side, not a replacement and a predecessor — AngsanaUPC and Angsana New both appear in the current Thai Supplemental Fonts list for Windows. “UPC” comes from the designer’s name, Unity Progress Corporation.

The difference that matters in practice is metrics: character widths, line heights and mark positioning are not identical between the two cuts. A legacy document laid out in AngsanaUPC will break lines in different places on a machine that only has Angsana New, changing pagination and shifting tables. Most “it printed differently from what I set” complaints trace back to this, not to the printer.

The fix is to install the whole set so files can call the exact cut they were laid out in, rather than substituting fonts document by document. The other UPC families that arrive in the same feature are DilleniaUPC, EucrosiaUPC, FreesiaUPC, IrisUPC, JasmineUPC, KodchiangUPC, LilyUPC and BrowalliaUPC.

Angsana New weights and styles

Microsoft lists four styles: Angsana New, Angsana New Bold, Angsana New Italic and Angsana New Bold Italic — two real weights, Regular and Bold, each with an italic companion. There is no Light, Medium, SemiBold or Black, and no variable-font version.

All four sit inside the single Angsana.ttc file, which is why copying the font between machines by dragging files so often comes up short: people look for four .ttf files that do not exist. Microsoft’s Windows 11 font list records the current version of that file as 5.05.

The font covers Thai and Latin — Microsoft’s OpenType data lists code pages 1874 Thai and 1252 Latin. A practical note: Thai stacks vowels and tone marks above and below the line, so Thai documents generally need a larger point size than a Latin document set for the same reading comfort. Test at real size before locking a template rather than inheriting values from an English one.

Where to download Angsana New (and fixing the missing font)

Microsoft offers no download. The Download row on the official page reads “N/A – Exclusively included with Microsoft products and services where applicable.” If your machine runs licensed Windows or Office, you already have the right to use it — the task is enabling it with the steps in the first section, not buying it and not downloading it.

Angsana New disappears from Windows 10 and 11 because Microsoft moved the Thai families out of the default install into an optional feature called Thai Supplemental Fonts, to reduce the operating system footprint, improve performance and optimise disk space. After a clean install or a cross-version upgrade, optional fonts are not enabled by default. Microsoft also states plainly that removing these fonts from the default install is a permanent change in behaviour that will remain in future releases. The only Thai font still in the default Windows 11 install is Leelawadee UI.

Are files from free font sites usable?

The Angsana.ttc and angsa.ttf files circulating on aggregator sites were extracted from Windows installations and carry no licence, because Microsoft has never sold or distributed this font as a standalone file. Installing them on a machine without a Windows or Office licence, or self-hosting them as a webfont, falls outside the licence completely. Use the steps in the first section, or move to an open-licensed family below.

Is Angsana New free? Can it be used commercially?

Free in the sense of being included in the Windows or Office licence you already paid for — not free in the open-licence sense. Commercial work on a properly licensed machine is fine: drafting contracts, producing reports, laying out books, exporting PDFs.

What is not permitted: redistributing the font files, embedding the font in non-Microsoft software or products, and self-hosting it as a webfont. Those require separate licensing through the enterprise route Microsoft links from its documentation. For web projects, starting from an open licence is faster and cheaper than negotiating.

Free Thai serif alternatives to Angsana New

If the document has to leave the Windows world — onto the web, to a printer, or to a colleague on a Mac — pick an open-licensed Thai serif from the start.

• Noto Serif Thai — the Thai serif from the Noto project under the SIL Open Font License, free for commercial use and web embedding. The closest match for the document-body role.
• Pridi — an OFL Thai serif with a more contemporary voice, better for editorial work that should not read as an official memo.
• TH Sarabun PSK — when the destination is a Thai government agency, this is the closer fit to the expected standard. See also the revised TH Sarabun New.
• Kinnari and Norasi — Thai serifs from the free font sets long used on Linux and in open-source document workflows.

Test them against your own copy in the font tester, or browse Thai serif fonts and free Thai fonts.

All 14 fonts that install together

Enabling Thai Supplemental Fonts once delivers all fourteen of Microsoft’s Thai families. Per Microsoft’s published list:

• Angsana New · AngsanaUPC
• Browallia New · BrowalliaUPC
• Cordia New · CordiaUPC
• DilleniaUPC · EucrosiaUPC · FreesiaUPC
• IrisUPC · JasmineUPC · KodchiangUPC · LilyUPC
• Leelawadee

If an old document opens garbled, install the whole set once rather than chasing individual files.

Best use cases

Angsana New is the default for formal Thai documents authored and read on Windows. Strong briefs:

• Formal Thai business correspondence in Microsoft Word — contracts, internal memos, official letters
• Legal documents and forms that still specify a Thai serif for body text
• Corporate templates that must stay compatible with thousands of existing files
• Academic work at Thai universities with fixed body-text formatting rules

Where it does not fit: websites (no webfont licence), brand and editorial print, and any job that requires shipping font files to a supplier. For those, Noto Serif Thai, Pridi or Niramit suit better; for a contemporary look, see Kanit and Prompt.

Pairings

Angsana New pairs inside Microsoft’s own Thai bundle, serving as the serif partner to Cordia New’s sans. Three pairings:

• Cordia New — the Unity Progress sans from the same year, for headings and UI
• Browallia New — the wider sans in the set, useful for separating heading levels
• TH Sarabun PSK — when the document is bound for a Thai public agency, move the body text to that standard

The Thai typography guide goes deeper on Thai-Latin pairing; the fonts directory has the full catalogue.

Licensing

Angsana New is proprietary software with Microsoft listed as the font vendor. Usage rights attach to that machine’s Windows or Office licence. There is no standalone sale, no public webfont licence, and no redistribution right. The official copyright line is ”© 1992 Unity Progress. Portions © 2004 The Monotype Corporation. Portions © 2015 Microsoft Corporation. All Rights Reserved.”

Microsoft’s product list for this font starts at Windows XP (font version 2.20) and runs through Windows 11, plus Office applications. Organisations needing rights beyond that scope must negotiate separately via the route linked from the Angsana New documentation. For work that should not involve licence negotiation at all, Noto Serif Thai and Pridi deliver Thai serif character under the SIL Open Font License with no conditions attached.

Frequently asked questions about Angsana New

Nearly every question about Angsana New is the same one — where the font went after a Windows reinstall and how to get it back without a third-party download — and the short, sourced answers are below.

Where can I download the Thai Angsana New font for Windows 11?

You do not download it. It is already on the machine as an optional feature. Enable it at Settings → System → Optional features → View features → Thai Supplemental Fonts → Next → Add, per Microsoft’s documentation. The PC must be online because Windows Update delivers the files. Copies on free-font sites carry no licence.

Why does Word have no Angsana New after a Windows upgrade?

Because Microsoft moved all fourteen Thai families into an optional feature that is not enabled after a clean install or upgrade. Microsoft describes this as a permanent change, so Word substitutes another font and lines reflow. Enabling Thai Supplemental Fonts once brings back Angsana New, Cordia New, Browallia New and every UPC family.

Can I use Angsana New on a Mac or iPhone?

Only inside Microsoft 365’s Office apps. Apple’s macOS Sonoma font list has no Angsana New and Microsoft distributes no standalone file, but Microsoft’s Cloud fonts in Office page lists Angsana New as a cloud font that Microsoft 365 subscribers can use in Word, Excel and PowerPoint on Mac, iOS, Android and the web. Apple’s system Thai font is Thonburi, a looped sans. For a Thai serif outside Office on a Mac, install Noto Serif Thai from Google Fonts by double-clicking the file and clicking Install in Font Book.

Do I need both Angsana New and AngsanaUPC?

Install both — and in practice they arrive together. Both live in the same Angsana.ttc file per Microsoft’s Windows 11 font list, and both switch on when you tick Thai Supplemental Fonts. Legacy documents laid out in AngsanaUPC get their original line breaks back once the exact cut they were set in is present.
