An online word counter processes any text you type or paste and instantly shows word count, character count, sentence count, paragraph count, and estimated reading time. No account needed, no installation, works in any browser.

Use the Word Counter for real-time word and character counts.

What an online word counter shows

The Word Counter displays:

MetricDescription
WordsTotal word count (whitespace-separated tokens)
CharactersTotal characters including spaces
Characters (no spaces)Characters excluding spaces
SentencesSentences ending with ., !, or ?
ParagraphsBlank-line-separated sections
Reading timeEstimated at 225 words per minute

All metrics update in real time as you type.

When to use an online word counter

SEO content writing: Blog posts need 1,500+ words for ranking depth. Monitor your word count as you write rather than finishing and discovering you’re at 800 words.

Meta description writing: Google truncates meta descriptions at ~155–160 characters. Paste your meta description and check the character count.

Academic writing: Essay word limits are strict. Count words as you write rather than at the end.

Social media: Twitter is 280 characters. LinkedIn posts perform best at 1,300–2,000 characters (engagement research). Facebook posts perform at 40–80 characters. Check character counts before posting.

Email subject lines: Subject lines above 60 characters get truncated in most email clients. Check before sending mass emails.

Freelance writing: Count deliverable words before invoicing.

Why different tools give different counts

You may get slightly different word counts from different tools. This happens because:

Hyphenated words: Is web-based one word or two? Most tools count it as one (split on whitespace, not hyphens). Some split on hyphens.

Numbers: Most tools count $1,234.56 as one word. Some don’t count numbers at all.

Contractions: don't, it's = 1 word each (no whitespace).

For consistency: Use the same tool for all your word count measurements if comparing across documents.

Reading time accuracy

The Word Counter uses 225 WPM — the median adult reading speed for general web content. Reading time estimates are approximate:

  • Technical articles with code examples take ~30% longer (adjust by multiplying by 1.3)
  • Academic content: 100–150 WPM (multiply by 1.5–2.0)
  • Fiction: 250–400 WPM (multiply by 0.6–0.9)

For a 1,500-word technical article: 1500 ÷ 225 × 1.3 ≈ 8.7 minutes. Display “9 min read.”

How to count words in specific document types

Microsoft Word: Shown in the status bar at the bottom. Or: Review → Word Count.

Google Docs: Tools → Word Count (Cmd/Ctrl + Shift + C).

VS Code / code editors: Most editors don’t show word count by default. Use the Word Counter — paste the content.

PDFs: Copy text (Ctrl+A, Ctrl+C) from the PDF and paste into the word counter. Note: some PDFs are image-based and don’t have selectable text.

Markdown files: Markdown formatting characters (asterisks, brackets, etc.) may inflate the count slightly. The actual rendered prose word count may be lower.
