Sentence Counter — Analyze Your Text's Sentence Structure
Paste your text to get an instant sentence count along with average sentence length. Perfect for improving readability and meeting assignment requirements.
Why Sentence Count Matters for Readability
Readability formulas like Flesch-Kincaid and Gunning Fog use average sentence length as a core variable. By knowing how many sentences your text contains, you can calculate whether your writing suits your target audience. Aim for 15-20 words per sentence for general audiences.
Improve Your Writing with Sentence Analysis
If every sentence in your essay is 30+ words long, readers will struggle. If they are all under 10 words, the writing may feel choppy. Use this sentence counter to find the right balance and create prose that flows naturally.
Frequently Asked Questions

Sentence count combined with average sentence length is a key readability indicator. Shorter sentences tend to be easier to read. Academic guidelines often suggest varying sentence length, and knowing your count helps you achieve that balance.
If your text ends without terminal punctuation, the tool still counts the trailing text as a sentence. This ensures you get an accurate count even for informal writing or notes.
