About this tool
AI models measure text in tokens, not words. As a rule of thumb, 1 token ≈ ¾ of an English word, or about 4 characters — so 1,000 words is roughly 1,300 tokens, and 1,000 tokens about 750 words. The exact number depends on the wording, language and punctuation.
Paste text for an exact GPT token count (with live word and character counts), or type a word count for a fast estimate. It's handy for fitting essays, articles, system prompts and documents inside a model's context window.
Words, characters and tokens explained
Characters are individual letters and symbols; words are space-separated; tokens are the sub-word pieces a model actually reads. A tokenizer keeps common words whole but splits rare or long words, so token counts sit between word and character counts for English text.
How many tokens per word by language
English averages about 0.75 words per token. Other Latin-script languages are similar, but Chinese, Japanese, Korean, Thai, Arabic and source code use more tokens for the same meaning — sometimes one token per character. Always check your real text rather than relying on a single ratio.

- Plan your prompt — Use the figures to stay within the model's context window.
Frequently asked questions
How many tokens is 1,000 words?
Roughly 1,300 tokens in English (1 token ≈ ¾ word). The exact count depends on the text — paste it above for a precise figure.
How many words is 1,000 tokens?
About 750 English words. Languages other than English and source code often use more tokens per word.
How many tokens is 500 words?
Around 650 tokens in English. Paste the actual text for an exact count, as punctuation and rare words change the result.
Why don't words and tokens match exactly?
Tokenizers split on sub-word pieces, spaces and punctuation, so common words may be one token while rare or long words are several.
Is the token count exact?
The count from pasted text uses the exact GPT (tiktoken) encoding. The words → tokens box is a quick estimate using the ¾-word rule.
