Why sentence length matters
Readers feel sentence length even when they never count it. A page of 30-word sentences tires people out; a page of 6-word sentences reads like a telegram. Skilled writers mix both — and the averages here help you see your pattern. For most web writing, an average between 12 and 20 words per sentence reads comfortably, with a few short sentences kept in reserve for emphasis. Like this one.
How to use it
- Paste your text — every figure updates as you type.
- Compare the longest sentence with the average. One giant outlier usually deserves a split.
- Need words, characters and reading time too? The Word Counter shows them all together.
Frequently asked questions
How does it decide where a sentence ends?
It looks for full stops, question marks and exclamation marks, and handles closing quotes and brackets. Abbreviations like "Dr." can occasionally be counted as an ending — every online counter shares this limit.
Does text without a final full stop count?
Yes — a trailing chunk of words with no ending punctuation is counted as one final sentence.
