Dense writing often comes from long words rather than long sentences, and that density is easy to miss when the wording feels precise.

Good to know
The average counts the letters and digits in each word and divides by the number of words, so punctuation and spaces between words are not included. Longer averages tend to read as more formal or technical, and the figure pairs well with a readability score.
Frequently asked questions
How is average word length measured?
It counts the letters and digits in each word, ignoring punctuation, then divides by the number of words.
Does punctuation count toward word length?
No. Only the letters and digits inside a word are counted, so a trailing comma or quote does not add to the length.
What does a higher average word length mean?
It usually signals denser or more technical vocabulary, which can be harder to read, so plainer words lower the average.
