Count Sentences

Count the number of sentences in any text, with word count and average words per sentence.

What is a Count Sentences?

A sentence counter counts the total number of sentences in a block of text by detecting sentence-ending punctuation.

Sentence count is a key indicator of writing complexity and readability. Short average sentence length (under 20 words) correlates with easier reading. Academic writing guidelines, content style guides, and readability scores like Flesch-Kincaid all reference sentence count. Counting manually is tedious on anything longer than a paragraph.
