About the Audiobook Speed

Text and reading calculators help writers, editors, and content creators analyze documents, estimate reading time, and understand vocabulary and structure.

Reading speed context

Average adult silent reading speed is 200–300 words per minute for comprehension; speed readers can reach 400–700 WPM with varying comprehension. Audio narration typically runs 130–150 WPM. Estimate reading time for your target audience: technical content is read more slowly (150–200 WPM) than light fiction (300+ WPM).

Word and character counts

  • Blog posts: 1,000–2,000 words for standard SEO; 2,000–4,000 for comprehensive coverage
  • Short-form social: 280 characters (Twitter/X), 2,200 (Instagram captions), 700 (Facebook posts)
  • Academic abstracts: 150–250 words; conference papers: 4,000–8,000 words
  • Average book: 70,000–90,000 words for fiction; 50,000–80,000 for non-fiction
