How is average word length calculated?

Each whitespace-separated token is stripped of leading and trailing punctuation characters. The lengths of the remaining tokens are summed and divided by the total number of tokens. The result is rounded to two decimal places.

Does punctuation count toward word length?

No. Punctuation attached to the start or end of a word (such as commas, periods, quotes, or parentheses) is stripped before measuring. Internal hyphens and apostrophes are kept, so "don't" counts as 5 letters.

What is a typical average word length in English?

Average English word length in running text is typically between 4 and 5 characters. Simple, conversational text tends toward 4, while academic or technical writing often exceeds 5.

What is a good average word length for readability?

For a general audience, an average word length around 4 to 5 characters reads easily. Below 4 feels very simple; above 6 signals dense, academic, or technical writing that may need editing for clarity.

Is my text sent to a server?

No. All analysis happens entirely in your browser. Your text never leaves your device.

What do the "Min" and "Max" values show?

"Min" is the length of the shortest word found in the text, and "Max" is the length of the longest word found. Single-character tokens (after punctuation stripping) are included.
