What is it
Character Counter is a free online tool that counts, in real time, how many characters, words, sentences, lines and paragraphs your text has. Simply type or paste the content into the text box to see the numbers change with each letter, without having to click any buttons.
In addition to the basic count, the tool calculates the estimated reading time of the text and evaluates the rhythm of the sentences, indicating whether they are Ideal, Tiring (sentences that are too long, without punctuation) or Chunky (very short sentences in sequence). This helps writers, content creators, and students review their own text before publishing or handing in work.
For those who write with SEO in mind, there is a word density analyzer: the system ignores articles, prepositions and other irrelevant words (so-called stop words) and shows the 3 most repeated words in the text, with the exact percentage of each one. This helps to check whether a keyword is being used in the right way, without seeming repetitive.
The tool also compares the size of your text with the most common limits on the internet: title for search engines (60 characters), meta description (155 characters), Instagram bio (150 characters), post on X (280 characters) and post on LinkedIn (3000 characters). Each limit appears on a progress bar that changes color as you approach or exceed the number.
How to use
- Paste or type your text into the tool's main box.
- Follow, at the top of the screen, the numbers of characters (with and without spaces), words, paragraphs and lines.
- See the estimated reading time and sentence rhythm right next to the counters.
- Check the word density panel to find out which terms are most repeated in your text.
- Look at the social media limit bars to see if the text fits in the title, meta description, Instagram bio, X or LinkedIn.
- Adjust the text as many times as you want: everything is recalculated instantly, without having to save or reload the page.
Tips
- For posts on X, keep an eye on the limit bar: it turns yellow near the end and red when you exceed 280 characters.
- A keyword density between 1% and 2% is usually considered healthy for SEO, avoiding excessive repetition of the same term.
- Sentences marked as Tired usually exceed 25 words: consider breaking them into two to make reading easier.
- All processing happens in your browser, so you can use the tool with drafts and internal texts without worrying about sending data to servers.
