What PSL Tamnanthai is

PSL Tamnanthai (พีเอสแอล ตำนานไทย) is a loopless Thai display face with squared, wide letterforms from PSL SmartLetter, the Bangkok commercial type foundry. It comes in four styles, Regular, Italic, Bold and Bold Italic, and it is a paid font with no legitimate free version. Its product page on fontpsl.com files it under PSL Series 4, which the PSL catalogue index lists at 93 fonts.

PSL’s About page credits the PSL fonts to Phanlop Thongsuk (พัลลพ ทองสุข), their creator and copyright owner, and gives PSL SmartLetter as his pen name, so we credit him as designer. The product page itself gives no release year. Searches for “PSL Tamnanthai”, “psl tamnanthai” and ฟอนต์ตำนานไทย all mean this font. The rest of the foundry’s catalogue is at PSL SmartLetter Thai fonts.

Letterforms

In the specimen on PSL’s product page, the Thai letters of PSL Tamnanthai have no head loops, an even stroke throughout, squared bodies with rounded corners, and noticeably wider proportions than most Thai faces. The Arabic numerals are drawn in the same wide, squared manner. It is a face for short words with a strong personality, not for running text.

The specimen shows Thai consonants and the numerals 0 to 9 in all four styles, but no Latin letters, so we cannot confirm whether the files carry a full English alphabet. If your job needs Thai and English in one typeface, ask PSL before buying, or pair it with a separate Latin face.

Why people look for it

PSL Tamnanthai is a font people see in use first and then try to name. In font-identification threads, the askers describe it as “old-style” and one answer calls it a “Lanna-style font” — terms PSL’s own product page does not use.

In a Pantip thread from April 2022, the asker posted an image and asked “ฟอนต์ไทยแบบนี้โบราณ อันนี้ชื่อว่าอะไรครับ” (what is this old-style Thai font called?). The answer the asker chose was “PSL TamnanThai ใช่หรือเปล่าคะ ฟอนต์แบบล้านนา” (is it PSL TamnanThai? a Lanna-style font). In a thread on the f0nt.com forum from January 2021, the asker was looking for something “old-style” and got the reply “ฟอนต์ PSL Tamnanthai ไม่ฟรีครับ” (the PSL Tamnanthai font is not free).

Both threads say the same thing: people recognise the font by its look, and the licence is where they get stuck. This page answers both: where to buy it legitimately, and what to use if you do not.

Where to buy PSL Tamnanthai

The legitimate channel is PSL SmartLetter itself. The PSL Tamnanthai product page on fontpsl.com is still up, but the psl.mundesigns.com web store showed an “under construction” page when we checked on 30 October 2026, so the online cart could not be used that day. Contact PSL through the contact page on fontpsl.com.

An archived copy of the store’s product page, saved by the Wayback Machine on 7 June 2026, lists the four-style PSL Tamnanthai Pro Family at ฿500, and Google’s stored results for the store still list PSL Tamnanthai Pro Regular and PSL Tamnanthai Pro Italic at ฿300 per style, but we could not open the store to confirm the current price. Treat it as indicative until PSL confirms it.

PSL Tamnanthai is not on Google Fonts and has no legitimate free download. The “free download” files on font aggregator sites are not a PSL channel. PSL’s “about our fonts” page shows a NECTEC document certifying that a font is a set of computer instructions, and legal documents certifying that PSL fonts are copyrighted.

Licensing

PSL Tamnanthai is sold under PSL’s own licence, which comes in three types: education, home use and commercial use. Unless the licence says otherwise, one licence covers one user or one computer, and the term starts at one year, according to PSL’s “about our fonts” page.

The commercial type names its users explicitly: print shops, sign shops, business-card shops, sticker-cutting shops, and companies or other juristic persons. Installing on several machines or for several users has to be stated in writing on the licence, or approved by the copyright owner first. The term can differ where the licence or a promotion says so.

In practice: a sign shop or studio using PSL Tamnanthai in client work needs the commercial type, not the home-use one, should count the machines it will install on, and should budget for renewal. The Thai font licensing guide explains how to check a licence, and other paid families are in premium Thai fonts.

Free alternatives

If a commercial licence is out of budget, choose by what you actually want from PSL Tamnanthai: the old-style flavour, or the squared loopless structure. No free font gives you both the way the original does.

• The old-style flavour: in the forum thread above, the reply recommended BLK-Pohchang (เพาะช่าง) by บางลี่โฆษณา (Bangli Advertising), which f0nt.com lists as free for commercial use, dated 9 October 2009 and tagged old-style, stone inscription and conservation. Its shapes are very different from PSL Tamnanthai, so set your real words in both before deciding.
• The squared loopless structure: Chakra Petch from Cadson Demak is OFL in five weights, and TH Chakra Petch is the original National Font. Both are loopless and free for commercial use, and Chakra Petch’s cut corners read as technical rather than old-style.

For a commercial loopless face from the same foundry, see PSL Display, compare others in loopless Thai fonts, and set your own text in the Thai font tester before you commit.
