TheNational Fonts (Thai:ฟอนต์แห่งชาติ;RTGS: [font] haeng chat)^[1] are 2 sets offree and open-sourcecomputer fonts for theThai script sponsored by theThai government. In 2001, the first set of fonts was released byNECTEC. The 3Thai typefaces in the set; Kinnari, Garuda and Norasi; were intended to be public alternatives to the widely used commercial typefaces.^[2] Later on, Thai Linux Working Group (TLWG) released these 3 typefaces alongside 10 others asFonts-TLWG software package.^[3][4] In 2006,^[5] a computer font competition was held. 13 of these typefaces won the competition and later got adopted by theGovernment of Thailand as public and official fonts. Later in 2021, another typeface,Chulabhorn Likhit was selected as the 14th typeface in the set. Thus, the set has gained the nickname offourteen National Fonts. The typefaces and all of their subsequently developed versions are released by theSoftware Industry Promotion Agency (SIPA), together with theDepartment of Intellectual Property throughf0nt.com. Hence another nickname for the set,SIPA fonts (ฟอนต์ซิป้า).^[6][7] In 2018, 13 of these typefaces from this set have been revised by a localfont foundryCadson Demak (คัดสรร ดีมาก), along withGoogle Fonts.^[8][9]

In 2001, the first "National Fonts" set was released byNECTEC. It contains threeThai typefaces: Kinnari, Garuda, and Norasi. These typefaces were intended to be public alternatives to the widely used, yet licence-restricted, commercial typefaces that came bundled with major operating systems and applications.^[2] Later on, Thai Linux Working Group (TLWG) released these 3 typefaces alongside 10 others asFonts-TLWG software package. Aside from Waree, the other 12 typefaces were released underGPL.^[3][4]

On 2 August 2006,^[5]Abhisit Vejjajiva'sCouncil of Ministers organised a competition to replace all existing fonts the Thai Government had bought from the private sector, includingMicrosoft's Angsana New, Browalia New, Cordia New, and EucrosiaUPC, which were extensively used at that time, with fonts created by Thai nationals. The competition was part of the "Standard Fonts for Thai Public Sectors" Project (โครงการฟอนต์มาตรฐานราชการไทย) proposed by theMinistry of Information and Communication Technology. The Ministry was quoted as saying: "...Various fonts are now used among the public agencies, that's why the state papers have never become standard. The fonts are also from the private companies which monopolise the rights over them, so we cannot use them as much as we should...".^[10][11]

On 7 September 2010, the Council of Ministers officially announced the thirteen fonts as the public fonts, naming them the "national fonts". The public agencies were ordered to use these fonts, especially TH Sarabun PSK, in their state papers. They were required to cease to use the private sector's fonts by 5 December 2010, KingBhumibol Adulyadej's 83rd birthday. The legislative branch and the judicial branch were also asked for cooperation.^[12]

In 2018,Cadson Demak a local font foundry worked withGoogle Fonts to revise all existing 13 National Fonts, providing them with more hinting, a wider range of weights, and betterUnicode support. There is also a new font "Thasadith"^[13] which was inspired by TH Srisakdi. All of those fonts were released underOpen Font License.^[8][14] Cadson Demak expected that the release of these revised National Fonts to Google Fonts would result in higher adoption of Thai looped typefaces compared to Thai loopless typefaces.^[9]

On 6 July 2021, the Council of Ministers officially approved the royal font set "Chulabhorn Likhit", the 14th Thai government standard font set as proposed by theChulabhorn Royal Academy. The font is named to celebratePrincess Chulabhorn on the occasion of her 64th birthday and her graduation from the Doctor of Philosophy program in the Visual Arts Department, Faculty of Painting, Sculpture and Graphic Arts atSilpakorn University.^[15]

The font "TH Sarabun PSK" is used on the current logo ofThai Wikipedia. This logo was designed by Pratya Singto (ปรัชญา สิงห์โต), agraphic designer who runs f0nt.com, and was adopted by the Community as itwon a competition in 2008 ^[th].^[16]

The font "TH Sarabun PSK" has been used in theGovernment Gazette of Thailand (Thai:ราชกิจจานุเบกษา;RTGS: Ratchakitchanubeksa) since January 2011, replacing Angsana New. The Gazette's first volume using such font is volume 128, part 1 A, dated 7 January 2011, in which the "Ministerial Regulation Determining the Criteria and Procedure for Acknowledging the Aircraft Type Certificates or Supplementary Type Certificates issues by the State Parties to the Conventions governing the Application for Certificates of Airworthiness or by the States with which Thailand has adopted the similar Agreements, BE 2553 (2010)" ("กฎกระทรวงกำหนดหลักเกณฑ์และวิธีการรับรองใบรับรองแบบอากาศยานหรือใบรับรองแบบส่วนเพิ่มเติมที่ออกโดยรัฐภาคีแห่งอนุสัญญาหรือประเทศที่ได้ทำความตกลงกับประเทศไทย เพื่อขอใบสำคัญสมควรเดินอากาศ พ.ศ. 2553") was published.^[17]
