Frequently asked questions
What is a sentence counter?
A sentence counter is a tool that automatically counts the number of sentences in your written work. It helps you track sentence structure, identify overly long or short sentences, and maintain clarity in your writing.
When should I use a sentence counter?
Use a sentence counter when editing content for readability, checking sentence variety, or meeting style guidelines. It’s especially helpful in marketing, academic, or professional writing where sentence flow and structure matter.
How do I use a sentence counter?
Simply paste your text into Grammarly’s sentence counter or start typing, and it will instantly display your total number of sentences, words, and characters. This helps you refine your writing as you go.
What’s the ideal sentence length for different types of content?
There’s no one-size-fits-all answer, but generally, sentences under 20 words are easier to read. For web and marketing content, aim for short, punchy sentences. In academic or technical writing, longer sentences may be acceptable if they remain clear. Here are some more details:
- Blog posts:
15–20 words per sentence (clear and reader-friendly) - Social media captions:
8–12 words per sentence (concise and engaging) - News articles:
20–25 words per sentence (informative yet easy to follow) - Academic papers:
20–30 words per sentence (detailed and structured) - Marketing copy:
10–15 words per sentence (persuasive and impactful)
Can a sentence counter help improve my writing?
Yes! By tracking sentence count and structure, you can identify overly complex sentences, run-ons, and choppy phrasing. This allows you to refine your writing for better readability.
How does a sentence counter differ from a word counter?
A word counter tracks the total number of words, while a sentence counter focuses on sentence structure and flow. Using both helps ensure your writing is clear, concise, and well balanced.
Does Grammarly’s sentence counter work with AI-powered writing tools?
Yes! Grammarly’s sentence counter works seamlessly with our free AI-powered tools. Use it alongside our blog post generator, cover letter generator, essay checker, and more.
