What is a Sentence Counter?

A Sentence Counter is a free online tool that counts the number of sentences in any text. Paste a paragraph, an essay or a full article and the Sentence Counter reads it and tells you how many sentences it holds, along with the word count, character count and paragraph count.

The tool marks the end of a sentence at a period, question mark or exclamation point. It also skips common abbreviations such as Mr., Dr. and etc. so the sentence count stays accurate. Students, writers, editors and teachers use the Sentence Counter to check the length and structure of their writing before they hand it in or publish it.

What sentence length tells you

Sentence length is one of the clearest signs of how easy your writing is to read. Use this scale while you edit, then check the average words per sentence shown by the Sentence Counter.

1 to 11 words12 to 20 words21 words and up
Quick tip: aim for an average around 15 to 20 words per sentence. The goal is not to make every sentence short, but to mix short and long sentences so the reader gets a natural rhythm.
Readability score explained

The Sentence Counter uses the Flesch reading ease formula, which is based on sentence length and word length. Match your score to the readers you write for.
