Its name is the Thai term for the tricolour, the national flag of Thailand. By the official account, the Thai letters are tall and narrow like those of older Thai printing types and finish in oval loops, proportions chosen to fit more text into a line without losing legibility. In the specimen the Latin has thin, flat serifs and a strong swing between heavy stems and hairlines, most visible in the Bold to Black cuts. The weights go from Thin 100 to Black 900, nine in all, each with an italic: 18 static styles and no variable version. The fonts hold 764 glyphs across Thai, Latin, Latin Extended and Vietnamese.

There is no variable font in the package. - **Look-alike Thai letters**: According to the official notes, ก ถ ภ ฤ ฦ and also ฎ and ฏ are close in shape, so very short Thai strings need a careful read. - **Designer field differs from the listing**: The official listing names Cadson Demak as designer; the font files give Katatrad Team as designer and Cadson Demak as manufacturer. - **Scripts stop at Thai and Latin**: Vietnamese and Latin Extended letters are present. Cyrillic and Greek alphabets are not. ## FAQs ### Is Trirong free for commercial use? Yes.
