How the sentence counter works
Last updated 10 November 2026
Sentence length affects how easy writing is to read. Counting sentences helps you see whether your text is made of short, clear sentences or long ones.
How it works
- Sentences are split at . ! and ? followed by a space.
- Words per sentence = words ÷ sentences, which you can work out from the counts.
Why count sentences
Long sentences make text harder to read. Counting sentences, and the average number of words in each, shows you at a glance whether your writing is made of short, clear sentences or long, winding ones. It is useful for emails, reports, applications and web copy.
How sentences are found
A sentence is counted when the text reaches a full stop, an exclamation mark or a question mark followed by a space or the end of the text. Paragraphs are counted at blank lines. Words per sentence is the number of words divided by the number of sentences.
Where counts can go wrong
- Abbreviations such as Dr. or etc. can look like the end of a sentence.
- Decimal numbers and website addresses contain full stops.
- Lists and headings without punctuation may be counted as part of one long sentence.
- Quotations that end in a question mark inside a longer sentence can add an extra count.
Aiming for readable writing
There is no perfect average, because readers and topics differ. As a guide, plain writing tends to mix short and medium sentences and keeps one idea in each. If one sentence runs on for several lines, try splitting it.
