What is a Sentence Counter?
A sentence counter is a free online tool that automatically counts the number of sentences in your text. Instead of manually counting each sentence (which is time-consuming and error-prone), you simply paste your text and get instant, accurate results.
Our sentence counter uses smart algorithms to identify sentence boundaries by recognizing periods, question marks, and exclamation points—while correctly handling tricky situations like abbreviations (Dr., Mrs., Inc.), decimal numbers (3.14, 99.9), and ellipses (...).
Whether you're a student checking essay requirements, a writer tracking your progress, or an editor analyzing document structure, this tool gives you the sentence count you need in seconds.

Frequently Asked Questions
How does a sentence counter work?
Our sentence counter uses advanced algorithms to identify sentence boundaries by detecting periods, question marks, and exclamation points—while intelligently handling abbreviations (Dr., Mr., Inc.), decimals (3.14, 99.9), and ellipses (...). This ensures accurate counts even in complex text with varied punctuation.
What counts as a sentence?
A sentence is a complete thought that begins with a capital letter and ends with terminal punctuation (. ! ?). Our tool counts declarative sentences, questions, exclamations, and commands. Sentence fragments, incomplete thoughts, or phrases without terminal punctuation are not counted as full sentences.
Is there a limit to how much text I can count?
No! Our sentence counter has no character or word limits. Count sentences in a short email or an entire novel—it handles documents of any size instantly. The tool processes everything locally in your browser, so even large texts are analyzed in milliseconds.
How accurate is this sentence counter?
Our sentence counter is highly accurate (99%+) because it uses intelligent punctuation analysis. Unlike simple counters that just count periods, ours correctly handles edge cases like "Dr. Smith has a Ph.D." (1 sentence, not 3), decimal numbers, ellipses, and quotations. For best results, use proper punctuation and capitalization in your text.
Can I count sentences in languages other than English?
Yes! Our sentence counter works with any language that uses standard terminal punctuation (. ! ?), including Spanish, French, German, Italian, Portuguese, and more. It accurately counts sentences in multilingual documents and handles special characters and accents without issues.
Do you save or store my text?
No, never. All sentence counting happens locally in your browser using JavaScript. Your text never leaves your device, never gets uploaded to our servers, and is never stored anywhere. You can use this tool with complete confidence for confidential documents, personal writing, or sensitive content.
What's the difference between a sentence counter and a word counter?
A sentence counter counts how many complete sentences are in your text (based on terminal punctuation), while a word counter counts individual words separated by spaces. Our tool provides both metrics—plus character count and paragraph count—so you get a complete analysis of your text structure.
