Practical tips for Thai text

Thai runs without spaces between words — Grammar Checker estimates word count using boundary detection. For platform character limits, the character count is the more reliable figure.
Working across Thai and English? Paste one language at a time in Grammar Checker — mixed-language drafts produce counts that reflect both vocabularies combined.
Grammar Checker analyses your Thai text as-is. Finish all edits before running the final check — late additions change every count and reading time estimate.

Does Grammar Checker count Thai (ไทย) accurately?

Yes. Grammar Checker uses Unicode segmentation, so Thai text is measured against the same standard the operating system uses. Thai characters paste cleanly and are counted at the grapheme level, including diacritics.

What's the difference between word and character counts for Thai?

Words are space- and punctuation-bounded tokens; characters are individual letters, marks, and spaces. Grammar Checker reports both so you can match whichever your platform uses — characters for limit-based fields, words for length goals.

Can Grammar Checker handle mixed Thai and English drafts?

Yes — grammar checker counts the combined text without distinguishing language. For accurate per-language stats, paste each language separately. Mixed drafts return a total that reflects both vocabularies together, which is fine for length checks but misleading for keyword density.

Does Grammar Checker work for Asia dialects of Thai?

Yes. Grammar Checker treats text uniformly across dialects in the Asia region. Spelling and word choice differ between dialects, but the count and analysis logic does not — you'll get consistent numbers regardless of regional variant.

Glossary

Vocabulary you'll see counting Thai

The vocabulary behind Grammar Checker, from word counts to readability.

Word countSource ↗: The total number of word tokens in a piece of text, typically derived by splitting on whitespace and punctuation. Common in publishing, education, and SEO as a length metric.
Character countSource ↗: The total number of code points (or graphemes, in Unicode-aware tools) in a text. Platforms like SMS and Twitter enforce limits in characters, not words.
UnicodeSource ↗: The international standard that assigns a unique number to every character in every script. Modern text tools use Unicode so counts work consistently across languages and emoji.
Grammar checkerSource ↗: Software that flags spelling, punctuation, and grammar issues by comparing input text against rule-based or statistical models of a language.
Intl.SegmenterSource ↗: A JavaScript API that splits text into Unicode graphemes, words, and sentences using the same locale rules browsers use natively. Tools that use it count complex scripts correctly.

How we count, and when this page was checked

Word and character counts on this page use the browser's Unicode-aware Intl.Segmenter API, so figures match the underlying graphemes rather than guessing from byte length. Reading-time estimates default to 238 wpm (Brysbaert, 2019). Last editorial review: 2026-05-23.
