The Sentence Counter analyses text to count sentences, words, characters, and paragraphs, while also calculating a readability score based on the Flesch Reading Ease formula. It is useful for writers, teachers, and content teams who want to ensure their writing is clear, appropriately complex, and hits specific length requirements.
Sentence length directly affects readability. Short sentences (under 15 words) are easy to scan and work well for web content. Longer sentences (25+ words) can convey complex ideas but risk losing readers. A healthy mix keeps content engaging. The Flesch Reading Ease score quantifies this - a score of 60 - 70 is considered standard for general audiences.
Paste or type your text into the input area. The counter updates in real time showing sentence count, average sentence length, word count, character count, paragraph count, and reading ease score. The readability indicator shows which audience level your content targets - from Very Easy (children's books) to Very Difficult (academic/legal texts).
