FAQs
What is average word length?
It is the mean number of characters per word in your text — total letters divided by total words. Shorter averages generally mean simpler, easier-to-read writing.
What is a good average word length?
Plain English typically averages 4 to 5 characters per word. Academic or technical writing often averages 5.5 or more. There is no single ideal — it depends on your audience.
How does word length relate to readability?
Longer words tend to be harder to read, which is why readability formulas consider word and syllable length. Keeping your average down usually makes text more accessible.
How are words counted?
Words are sequences of letters and digits; surrounding punctuation is stripped before measuring length, so “hello,” counts as 5 characters.
Is my text sent to a server?
No. The calculator runs entirely in your browser with JavaScript, so your text never leaves your device.
