How to use the Word Counter

  1. 1

    Type or paste your text into the text area.

  2. 2

    Eight statistics, target-length progress, and frequent terms update instantly as you type.

  3. 3

    Use 'Copy results' to copy the statistics to your clipboard, or 'Clear' to reset the input.

Features

  • Real-time counting: Results update instantly as you type — no button to press.
  • Language-aware segmentation: Uses Intl.Segmenter when available for languages that do not rely on spaces; results can vary with browser segmentation rules.
  • Eight metrics at once: characters, words, sentences, paragraphs, lines, UTF-8 bytes, and reading time on one screen.
  • Input analysis runs in this browser tab and the counting action does not upload the entered text.

FAQ

Q. Can it accurately count Japanese or Chinese words?

A. Yes. The Intl.Segmenter API performs language-aware word segmentation for Japanese, Chinese, Korean, and other non-space-separated languages. Browsers that don't support Segmenter automatically fall back to space-based counting.

Q. Is there a character limit?

A. There is no fixed input limit, but extremely long documents can update more slowly depending on device performance.

Q. Can I use it to check social media character limits?

A. Yes. It's ideal for checking Twitter/X's 280-character limit, Instagram captions, email lengths, and any other platform character restrictions.

Q. How are spaces and line breaks counted?

A. Characters (with spaces) counts every space, tab, and newline as one character. Characters (no spaces) excludes all whitespace — only visible characters are counted. Line count equals the number of newline characters plus one.

Q. Are HTML tags or Markdown syntax included in the count?

A. Yes. The tool counts the raw text as typed, so HTML tags (<p>, <br>, etc.) and Markdown syntax (#, **, -, etc.) are each counted as individual characters. To count only the visible content, paste the plain text without any markup.

Technical Deep Dive: How Character Counting Works

JavaScript's str.length returns UTF-16 code units rather than visible characters. This tool uses Intl.Segmenter with grapheme granularity, so joined emoji and combining-mark sequences are counted as user-perceived characters.

Word segmentation uses Intl.Segmenter with word granularity where the browser supports it. This is more useful than whitespace splitting for Japanese, Chinese, and Thai, but segment boundaries are browser- and locale-dependent and should not be treated as a linguistic guarantee.

Line count is the number of newline characters plus one. Windows CRLF endings are normalized to LF first, and an empty input reports zero lines.

The 'no-spaces' character count strips all whitespace using the regular expression /[\s\u3000]/g, which covers ASCII spaces (U+0020), full-width Japanese spaces (U+3000), tabs (U+0009), and all newline variants. This ensures full-width spaces common in Japanese text are excluded alongside standard ASCII whitespace.

Data Handling & Security Notes

Counting uses browser string APIs and does not make a request that uploads the text entered into the tool.

Page assets and unrelated browser activity can still create network entries. To inspect the action, let the page finish loading, clear the DevTools Network log, and type recognizable dummy text.

Input is held in React state for the current page session and is not intentionally persisted by this tool. Shared devices, extensions, clipboard history, and screen capture remain separate risks.

Practical Examples, Cautions, and Common Mistakes

Examples

  • Check article titles, meta descriptions, and social posts before publishing.
  • Verify application essays, reports, and form answers against length limits.
  • Compare original and translated text length before deciding whether to summarize.

Cautions

  • Counting rules differ by platform, so always confirm the final submission rule.
  • Emoji and combined characters may be counted differently by external services.
  • Line breaks and full-width spaces can change totals depending on the metric you use.

Common Mistakes

  • Optimizing only for character count while ignoring readability and search intent.
  • Counting copied text with extra signatures, spaces, or pasted boilerplate included.
  • Comparing Japanese character counts and English word counts as if they were equivalent.
