Word Counter: Track Words, Characters, Sentences, and Reading Time
Key Points
- Average reading speed is 200-250 words per minute—use word count to estimate reading time
- Character counts matter for social media (Twitter: 280 chars), SEO meta descriptions (155 chars), and SMS (160 chars)
- Word count requirements are standard in academic papers, articles, and professional writing
Word and character counts are essential metrics for writers, students, marketers, and developers. Whether you're hitting a word count requirement for an essay, staying within character limits for social media, or estimating reading time for a blog post, precise counting tools help you write to specification.

Average words read per minute
Common Use Cases
Academic Writing
Essays, theses, and research papers have strict word count requirements. Track your count in real time to stay within the 500-word essay or 10,000-word thesis limit.
Social Media & Marketing Copy
Twitter limits posts to 280 characters. Meta descriptions should be 150-160 characters. Ad copy often has strict character limits. Count before publishing.
Blog Post & Article Planning
SEO best practices suggest 1,500-2,500 words for in-depth articles. Estimate reading time (word count / 250) to set reader expectations.
Translation & Localization
Translation costs are often per-word. Get an accurate word count before requesting quotes from translators to budget accurately.
Writing Tips
For SEO blog posts, aim for 1,500+ words for in-depth topics—but prioritize quality over hitting a number.
Reading time estimate: divide word count by 250 for adults, 200 for technical content.
Check character count including spaces (for most limits) AND excluding spaces (for some international standards).
Use paragraph count and sentence count to gauge content structure—too many long paragraphs hurts readability.
