Word count, reading time, keyword density, and character frequency — instantly
Character Counter and Text Analyzer counts characters, words, sentences, paragraphs, and lines in any pasted or typed text. It shows character count with and without spaces, word count, estimated reading time, sentence count, paragraph count, average word length, and the top 10 most frequent words. All analysis happens locally in your browser — text is never sent to a server.
Character limits matter across many platforms: Twitter/X (280 characters per tweet), Instagram captions (2,200 characters), Facebook posts (63,206 characters), LinkedIn posts (3,000 characters), meta descriptions (155-160 characters), SMS (160 characters per message, 153 in a multi-part SMS). Keyword density analysis (from the top words list) helps with SEO — aim for 1-3% density for a target keyword in body text.
Reading time is estimated at 238 words per minute (average adult reading speed for online content, per Nielsen Norman Group research). Academic texts are read at 150-200 wpm. Technical documentation: 200-250 wpm. Fiction: 250-300 wpm. The estimator uses 238 wpm as a widely-used default for web content.

Result: 280 chars per tweet / 'Your text: 1,847 chars → 7 tweets needed'
SEO meta description
Result: 155-160 chars ideal / 'Your description: 167 chars → trim by 7-12 chars'
5-minute blog post length
Result: Reading time = word count ÷ 238 / 5 min × 238 = ~1,190 words minimum
What is the ideal blog post length for SEO?
According to multiple SEO studies (Backlinko, HubSpot, SEMrush), the average first-page Google result has 1,400-1,500 words. Long-form content (2,000-3,000 words) tends to earn more backlinks and higher rankings for competitive keywords. However, length should serve the reader — a 500-word post that perfectly answers a simple question outperforms a padded 3,000-word post. Write to the topic, not to a word count.
How many characters is a page of text?
A standard manuscript page (12pt font, double-spaced, 1-inch margins) is approximately 250 words = 1,300-1,500 characters. A single-spaced business page is approximately 400-500 words = 2,200-2,800 characters. An average paperback novel page is approximately 250-300 words.
What is keyword density and how do I calculate it?
Keyword density = (keyword occurrences ÷ total word count) × 100. If your target keyword appears 12 times in a 1,000-word article, density is 1.2%. Google's guidelines don't specify an ideal density, but SEO practitioners generally recommend 1-3%. Higher density risks 'keyword stuffing' penalties. Use semantic variations (LSI keywords) rather than over-repeating exact phrases.
How long does it take to read 1,000 words?
At 238 words per minute (average adult online reading speed): 1,000 words ≈ 4.2 minutes. At 150 wpm (slower technical reading): ≈ 6.7 minutes. At 300 wpm (faster general reading): ≈ 3.3 minutes. Medium.com's reading time estimates use 265 wpm. The New York Times uses 250 wpm. Reading time estimates are approximate — complex content takes longer than simple narrative.
What is the difference between characters and bytes?
ASCII characters (English letters, digits, common punctuation) use 1 byte each. Non-ASCII characters (accented letters, CJK characters, emoji) use 2-4 bytes in UTF-8. Twitter counts characters (not bytes) — an emoji counts as 2 characters in Twitter's counter. When storing text in a database, VARCHAR column lengths are often in bytes, not characters — a VARCHAR(255) might only hold 63-85 UTF-8 emoji characters.
