Quick definition
What are Thai translation services?
Thai translation services convert content between Thai and other languages for readers in Thailand and Thai-speaking communities worldwide. Professional Thai translation handles a tonal language written without spaces between words, polite registers, and local conventions such as Buddhist Era dates, so content reads naturally and displays correctly.

Language challenges
What makes Thai translation difficult?
The US Foreign Service Institute places Thai in Category III, languages with significant differences from English. These are the issues we manage on every Thai project:
No spaces between words
Websites, apps and subtitles need deliberate line-break handling so Thai text wraps in the right places.
Tones and tone marks
A missing or wrong tone mark changes meaning, so proofreading by native linguists is essential.
Polite registers
Formal Thai, polite particles and royal vocabulary must match the reader and the context.
Buddhist Era dates
Official and consumer content often needs B.E. years alongside or instead of Gregorian years.
Fonts and line height
Stacked vowel and tone marks need fonts and line spacing that render cleanly.
English loanwords
Technical and brand terms may stay in English, be transliterated or be translated, and need consistency.
How does Thai differ from English in localization?
Thai needs more than translation. These are the differences we plan for on websites, apps and print.
| English | Thai | What we do | |
|---|---|---|---|
| Script | Latin alphabet, 26 letters | 44 consonants plus vowel and tone marks | Use fonts that render stacked marks cleanly |
| Word spacing | Spaces between words | No spaces between words | Handle line breaks for web, app and subtitle text |
| Tone | Not written | Five tones shown with marks and letter classes | Native proofreading of every tone mark |
| Dates | Gregorian calendar | Buddhist Era years, 543 years ahead | Follow your channel and audience conventions |
| Formality | Neutral you | Polite particles and formal registers | Agree one register for your brand |

Frequently Asked Questions About Thai Translation
How much does Thai translation cost?
Thai translation is usually priced per source word. The rate depends on subject matter, file format, turnaround and any desktop publishing needed. Send us your files and we will provide a detailed quote.
Why is Thai difficult to translate and typeset?
Thai is tonal, uses its own script with stacked vowel and tone marks, and does not put spaces between words. Accurate tone marks, suitable fonts and careful line breaking are essential.
Do Thai documents need Buddhist Era dates?
Official Thai documents commonly use the Buddhist Era, which is 543 years ahead of the Gregorian year. We follow the convention your audience and channel expect.
Do you provide certified Thai translations?
Yes. We provide certified Thai translations of business, legal and personal documents with a signed statement of accuracy. Requirements vary by authority, so tell us where the translation will be submitted.
