Understanding the science and methodology behind our reading time calculations
Based on extensive research showing that average adult silent reading speed ranges from 200-250 words per minute.
Based on average speaking speed for clear, comprehensible speech in presentations and audiobooks.
Words are identified by splitting text on whitespace and filtering out empty strings.
Includes all characters including spaces, punctuation, and line breaks.
Reading time = Word count ÷ Reading speed (WPM)
We use PDF.js to extract text content from PDF documents. The library processes each page and combines the text for analysis.
Plain text files (.txt) are processed directly using the browser's built-in file reading capabilities.
Calculated by dividing total characters by word count. Helps indicate text complexity.
Based on 250 words per page, which is the standard for double-spaced, 12-point font documents.
Rough estimate based on 100 words per paragraph, typical for web content and articles.
These calculations provide estimates based on average reading speeds. Individual reading times may vary significantly based on text complexity, reader experience, and reading purpose. Use these metrics as general guidelines rather than precise measurements.
