Tokens per character
A common rule of thumb is one token per four characters of English text. Enter a character count to estimate tokens.
Approximate for English prose (about 1.33 tokens per word, 4 characters per token). Counts vary by tokenizer and language. For an exact GPT count, paste your text into the counter.
The four-characters-per-token rule
A widely used estimate is one token per four characters of English text, including spaces. It is convenient because character count is trivial to measure, but it is only an average: dense code or non-English scripts can run closer to two or three characters per token, using more tokens than the rule suggests.
FAQ
Is four characters per token exact?
No, it is an average for English. For an exact count, paste the text into the token counter, which uses the real GPT tokenizer.
