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.

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.
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.

| 90 to 100 | 5th grade | Young readers, simple steps | Very easy |
