Word Counter

The average adult reads 200–250 words per minute for non-fiction prose. This counter uses 238 WPM as the baseline, derived from multiple studies on adult silent reading. Skilled readers and those familiar with the subject matter often reach 300+ WPM. Screen reading is typically 20–30% slower than print reading. The reading time displayed is a rough estimate — actual time varies significantly based on text complexity, subject familiarity, and individual reading speed.

A standard double-spaced academic page (12pt Times New Roman, 1-inch margins) is approximately 250–300 words. Single-spaced is about 500–600 words per page. Reference counts for common formats: a novel is 80,000–100,000 words; a novella 17,500–40,000 words; a short story 1,000–7,500 words; a blog post 500–2,500 words; a tweet 10–30 words; a LinkedIn post 150–300 words for best engagement. A 5-minute speech at 130 WPM is approximately 650 words.

Twitter/X allows 280 characters per post (expanded from 140 in 2017). URLs count as 23 characters regardless of actual length. Instagram captions allow 2,200 characters but only the first 125 are visible without tapping "more." LinkedIn posts allow 3,000 characters. LinkedIn articles have no practical limit. SMS messages are 160 characters in GSM-7 encoding; messages with non-standard characters (emoji, accented letters) use UCS-2 encoding and are limited to 70 characters per segment. Meta descriptions for SEO should be 150–160 characters; page titles 50–60 characters to avoid truncation in search results.

This tool counts sentence-ending punctuation: periods, exclamation marks, and question marks. Consecutive punctuation (like "...") counts as one. Abbreviations such as "Dr.", "U.S.A.", "etc." may cause slight overcounting because they contain periods. For very short texts with no sentence-ending punctuation, the count defaults to 1 if any text is present. Academic readability formulas like Flesch-Kincaid define sentences the same way. For a more accurate count in complex texts with many abbreviations, dedicated grammar-checking tools are more reliable.

Keyword density is the percentage of times a keyword appears relative to the total word count: (keyword count / total words) × 100. The "Top Words" section above shows the most frequent meaningful words in your text, which approximates your keyword density. For SEO, keyword density guidelines have evolved significantly: search engines now focus on topical relevance and natural language rather than keyword frequency. Keyword stuffing (excessive repetition) is penalized. A natural density of 1–3% for primary keywords is generally accepted. Focus on semantic variations and related terms rather than exact-match repetition.

Research from multiple SEO studies suggests different optimal lengths depending on the goal. For ranking in competitive search results: 1,500–2,500 words tends to perform well for most topics. Long-form content (3,000–4,000+ words) ranks better for highly competitive terms because it provides more comprehensive coverage. However, quality beats length: a concise 800-word post that fully answers the search intent outperforms a padded 3,000-word post. Local business pages and simple informational queries often rank with 300–600 words. The right length is whatever it takes to fully answer the user's question.

Reading time uses 238 WPM (average adult silent reading speed). Speaking time uses 130 WPM, which is the average conversational speaking rate for presentations and public speaking. Professional broadcasters and fast speakers reach 150–180 WPM. Slow, deliberate speech for formal speeches or teaching is around 100–110 WPM. The US Federal Register defines "standard" speech at 140 WPM for public comment timing. If you are preparing a speech, calculate your actual rate by reading a 500-word sample aloud and timing yourself, then adjust the estimate accordingly.

This counter defines a word as any sequence of non-whitespace characters separated by spaces, tabs, or line breaks. This matches how most word processors (Microsoft Word, Google Docs) count words. Hyphenated words like "well-being" count as one word. Numbers ("42", "3.14") count as words. Contractions ("don't", "it's") count as one word each. URLs count as one word. This matches the industry standard definition. Some academic submission systems count differently — check specific requirements, as there can be a variance of up to 5% between counting methods for the same text.

Average sentence length (ASL) is total words divided by total sentences. Readability formulas like Flesch-Kincaid and Gunning Fog heavily weight sentence length: longer sentences are harder to read. Guidelines by reading level: elementary school: 8–10 words per sentence; average adult: 15–20 words; academic writing: 20–25 words; legal/technical documents: 25+ words (often too complex). Best practices for web content: aim for 15–20 words per sentence on average. Vary sentence length for rhythm — a short sentence after two long ones creates emphasis. The most readable writing mixes sentence lengths deliberately.

Unique word count (also called vocabulary richness or type-token ratio when divided by total words) measures lexical diversity. A high ratio suggests varied, rich vocabulary. A low ratio may indicate repetition. Type-token ratio = unique words / total words × 100. In natural speech: around 40–60%. In quality writing: 60–80%. In very short texts, the ratio is artificially high because every word is likely unique. For academic writing, a vocabulary richness score above 70% is generally considered strong. This metric also helps detect AI-generated content, which tends to have lower lexical diversity than human writing on the same topic.
