What is a sentence counter?
Exactly what it sounds like. QuillBot’s sentence counter counts your sentences, so you can benchmark your project’s progress.
There’s no need to paste your piece elsewhere or manually count those periods when you’re using our sentence count checker.
When do I use a sentence counter?
Paragraph and sentence counters have a variety of uses, from helping you check your daily writing goals to meeting assignment requirements to creating viral content that’s just the right length.
How do I use an online sentence counter?
To use QuillBot’s free online sentence counter tool, just type or paste in your text, and our sentence counter will instantly—you guessed it—count the number of sentences.
Once you've finished working on your text, use the trash can icon in the top right corner to clear the window for a fresh start.
If you’ve changed or refined your text to meet a target sentence count, you can easily download or copy the updated text to your clipboard using the icons in the bottom right corner.
Who can benefit from using a sentence counter?
Students
Hitting the proper sentence count in an essay or response isn’t easy. Students can use our sentence counter to prevent work from going too long or too short.
Writers
Daily goals are vital for any writer, whether you’re an established author, an aspiring hobbyist, or a casual journaler. Our sentence counter can help you hit those goals.
Job seekers
When crafting cover letters or completing case studies for job applications, meeting a target sentence count could be the difference between making it to the next round or getting that “maybe next time” email.
Educators and researchers
Research abstracts and similar essays often have a strict minimum sentence count that can be difficult to achieve without a sentence counter tool.
How is QuillBot’s sentence counter different from other sentence counters online?
See everything you need (and more) at once
The word and character counts are displayed side by side, so whether you’re reviewing one or both for your project, there’s no extra clicking, hovering, or changing tabs to see one count or the other.
Plus, you can also see the character count for optimized Facebook posts (250 characters) and the hard limit for Twitter posts (280 characters) displayed right on the page in the bottom right-hand corner.
There’s no clutter
QuillBot’s sentence counter has a clean, intuitive, and clutter-free interface. You won’t be bothered by pop-ups or noisy ads, and it’s free.
Sentence counter FAQs
Is QuillBot's sentence counter tool free to use?
Yes. Just paste your text into our online sentence counter and let it do the work. No paywalls, no nonsense.
Can a sentence counter correctly identify sentences with abbreviations or numbers (e.g., Mr. Smith or 3.14)?
Absolutely. Our sentence counter tool is smart enough to know that “Mr.” doesn’t end the sentence and “3.14” isn’t a new thought. We keep our sentence counter accurate so your work is mistake-free.
What's the difference between a sentence counter and a word counter?
A word counter counts words and a sentence counter counts sentences. Think steps vs. miles. Beats vs. dance moves. Bricks vs. walls. Both are useful, but our paragraph and sentence counter gives you the bigger picture.
What is the ideal sentence length for better readability?
Sweet spot: 15–20 words. Long enough to say something smart; short enough to keep your readers awake.
Does sentence length affect the rhythm and flow of my writing?
Big time. If your sentences are too long, you lull your reader to sleep. If they’re too short, they’ll feel choppy. And if they’re all the same length, the piece will lack that spice that keeps readers engaged.
Can I use this sentence counter on my mobile device?
Yes. Whether you’re on your laptop, tablet, or phone, our online sentence counter plays nice with all screens.
Is the text I paste into the sentence counter saved or stored?
What you paste stays yours. Our sentence counter tool doesn’t save, store, or sneak a peek at your writing.
