# Roman-like Thai Typography (modern loopless Thai)

> A Thai type genre that drops the head loops of most Thai letters, so the script reads as an even sans like Helvetica. Older loopless forms exist, but this line began with Manop Srisomporn's Manoptica, drawn from 1973 for dry transfer; Manop faces spread through advertising and road signs, and Cadson Demak's corporate fonts (AIS's among them) carried it into branding and screens. Since 1999 it has also been set as body text in magazines, screens and operating systems, which remains controversial; families now ship looped and loopless Thai side by side, mostly recommending loopless for display.

- Period: 1973–present
- Where: Southeast Asia
- Origin: Bangkok, Thailand: the dry-transfer lettering of Manop Srisomporn, a commercial letterer who from 1973 drew Manoptica, a Thai face without head loops, in response to the Helvetica then printed on imported goods. Dry transfer, which DHA Siamwalla brought to Thailand with the transfer-sheet maker Mecanorma, carried his Manop faces into advertising, offset print and government signage; Cadson Demak (founded 2002) took the loopless look into corporate fonts and screen type. Loopless Thai as such is older: unlooped letters were normal in the Sukhothai period, fast handwriting lets head loops fall open, and designs that truncate or omit the loop were used in sign-making and decorative text from the nineteenth century. This entry covers only the monoline, Latin-sans-modelled line that began with Manoptica, not those older hand forms
- Branch: Rational modernism
- Also known as: Loopless Thai, Roman-like Thai typefaces (แบบตัวพิมพ์ไทยเสมือนโรมัน), Thai Modern (Linotype's name for the loopless styles of Neue Frutiger Thai)

## Use it with care

Loopless Thai is contested inside Thailand. Researchers such as Rachapoom Punsongserm find it harder to read in small, bold or justified body text and less legible across viewing distances than a Thai universal-design face, with letters that can be taken for Latin (พ.ร.บ. can read as W.S.U.), so keep it mostly to display sizes and set body, legal and small interface text in a looped face. Critics also see it as eroding the looped forms that mark Thai identity, and Cadson Demak, which popularised it, has since turned back towards looped faces. Have every Thai word checked by a fluent reader, since image models invent or garble Thai letters, and never pass shaped Latin letters off as Thai.

## How it works

- Drop the head loops: end Thai strokes in plain terminals of even weight (flat, squared or rounded), so the letters take on the colour of a Latin sans, most often a neo-grotesque like Helvetica, but also humanist or geometric models.
- Keep apart the letters that become confusable without loops (ก ถ ภ, บ ป, ข ช, ฎ ฏ) through width, notches, tails and the placement of vowels and tone marks, or keep a reduced 'obscure' head, a small slab or nib, where the face must also work as text.
- Use the loopless form above all for display: set headlines, packaging, advertising, signs, logotypes and interface headings large, heavy and tight; where running text or small interface text must also be loopless, use an obscure-loop or crossover face, and otherwise set it in a looped companion.
- Match the Thai to its Latin partner in weight, proportion and terminal shape, so both scripts read as one modern sans family in a brand, a sign or an interface.
- Leave out ornament, flourishes and traditional Thai motifs; let the stripped letterform, over flat colour or photography, carry a modern, commercial voice.
