About the Word & Character Counter

A word count is rarely enough on its own. Whether you're optimizing a blog post for SEO, checking a tweet fits within 280 characters, or assessing whether an essay is readable for your target audience, you need more than a single number. This tool gives you words, characters, sentences, paragraphs, reading time, speaking time, Flesch-Kincaid readability, keyword density, and platform-specific character limits — all updating as you type.

What this tool measures

Core Counts

Words, characters (with and without spaces), sentences, paragraphs, and lines — the fundamentals for any writing task.

Readability

Flesch Reading Ease and Flesch-Kincaid Grade Level scores tell you how accessible your writing is for your target audience.

Platform Limits

Real-time indicators for Twitter/X (280), LinkedIn (3000), meta descriptions (160), and essay targets — highlights when you're over the limit.

Keyword Density

Top keywords ranked by frequency with a word cloud visualization — useful for SEO content audits and avoiding keyword stuffing.

Recommended content lengths

  • SEO blog post: 1,500–2,500 words for competitive topics
  • Meta description: 150–160 characters
  • Twitter/X post: up to 280 characters
  • LinkedIn post: 150–300 words for best engagement
  • Email subject line: 40–60 characters

Frequently asked

Is my text sent to a server?
No. All counting, readability analysis, and keyword extraction run 100% in your browser. Your text never leaves your device.
How is reading time calculated?
Reading time is estimated at 200 words per minute (the average adult silent reading speed). Speaking time uses 130 WPM, which is a comfortable presentation pace. You can adjust the WPM in the tool.
What is the Flesch-Kincaid reading ease score?
The Flesch Reading Ease score rates text on a 0–100 scale. Higher scores mean easier to read. 60–70 is plain English suitable for most audiences. Below 30 is very difficult (academic/legal). The grade level score estimates the US school grade needed to understand the text.
What is the ideal meta description length?
Google typically displays 150–160 characters of a meta description on desktop. The tool highlights when you exceed this limit in the SEO limits panel.
What is the Twitter/X character limit?
Twitter/X allows 280 characters per post. URLs count as 23 characters regardless of their actual length. The tool shows your remaining character count in real time.
