Count words and characters as you type

The Word & Character Counter gives you live statistics for any text: words, characters (with and without spaces), sentences, lines, and estimated reading time. The counts update instantly as you type or paste, so you can hit a length target for a meta description, a tweet, an essay, or a form field without guessing. It is a fast, distraction-free way to measure text.

How it works

Everything is calculated locally in your browser with JavaScript. As soon as text enters the box, the tool tokenizes it into words and sentences and tallies characters and lines, then estimates reading time from a typical reading speed. Because nothing is uploaded, you can measure drafts, private notes, or client copy with full confidence that it stays on your device.

Practical use cases

  • Fit copy within a character limit for titles, bios, or SEO tags.
  • Track essay or article length against a word target.
  • Estimate how long a blog post will take readers to finish.
  • Check line counts for code comments or plain-text lists.

To reshape text before counting, the Case Converter and Remove Line Breaks are handy companions, and the Text Diff Checker lets you compare two versions once the length is right.

Private by design

Since all counting happens in-browser, no data is uploaded and nothing is stored. The tool is free, requires no account, and works on all modern browsers including phones. Close the tab and your text is gone.

Frequently asked questions

Both. The tool shows total characters including spaces and a separate count excluding spaces, so you can match whichever limit you need.
