Localize App Store Screenshots to Thai
ไทย
Thailand = ~70M people, high smartphone penetration.
Why Thai matters
Thailand's ~70M people are among the world's heaviest mobile-social and live-commerce users, and Thai shoppers buy comfortably inside apps. Thai is written with no spaces between words (spaces mark phrase or sentence breaks instead), so naive wrapping splits words mid-cluster, and the script stacks up to three vertical levels (consonant, vowel, tone mark) that collide without extra line-height.

Localization tips for Thai
- 1 Thai has no inter-word spaces. Use a dictionary-based Thai line-breaker (ICU/libthai) or text wraps mid-word and becomes unreadable.
- 2 Thai stacks vertically (base consonant, lower vowel (ุ ู), upper vowel (ิ ี ึ ื), and tone mark (่ ้ ๊ ๋)), so raise line-height ~40-60% or the marks clip the line above.
- 3 Choose loop style deliberately: looped Thai (with หัว head-loops, e.g. Sarabun) reads formal and official; loopless display faces (Kanit, Sukhumvit) read modern and trendy.
- 4 Keep a friendly-polite tone; the polite particles ครับ (male speaker) / ค่ะ (female) are usually dropped in short headlines but define register elsewhere.
- 5 Use Arabic numerals (123), not Thai numerals (๑๒๓). Thai digits look archaic in app UI even though they are technically more localized.
- 6 Partial localization is fine. Thai users read English UI labels alongside Thai headlines, so brand and tech terms can stay in English.
Fonts for Thai
Noto Sans Thai, IBM Plex Sans Thai, and Sarabun (a Thai government-standard looped face). Pick by loop style. Looped fonts carry the traditional head-loops and stack tone marks cleanly, while loopless display faces like Kanit look modern but need generous line-height so upper vowels and tone marks don't clip.
Most common mistake
Letting your design tool wrap Thai on character boundaries, which cuts words in half, and leaving line-height at Latin defaults, which clips the stacked tone marks (่ ้ ๊ ๋) sitting above tall vowels. Both make otherwise-correct Thai look broken.
