Reading & Speech Pacing Tips
Standard Blog Reading Speed
Major publications like Medium and Substack use 200–250 WPM (default: 225 WPM) as their baseline benchmark for calculating 'X min read' badges.
Presentation & Keynote Pacing
Public speakers typically deliver 120–140 WPM. Slowing down to 110–120 WPM ensures complex technical points resonate clearly with audiences.
Flesch Reading Ease Score
Scores between 60–70 indicate standard plain English accessible to 8th-grade students. Scores below 50 reflect dense academic or legal prose.

Frequently Asked Questions
How does the Reading Time Calculator estimate reading durations?
Our calculator measures the total word count and calculates the duration using standard reading speed benchmarks (225 words per minute by default, as used by major publication platforms like Medium). You can also calibrate the WPM to match fast, slow, or presentation speaking speeds.
What is the difference between reading time and speech duration?
Silent reading is significantly faster (~200–250 WPM) because your brain processes visual text rapidly without physical speech constraints. Verbal speeches, keynotes, and podcast narrations typically occur at ~120–150 WPM to ensure proper audience comprehension and rhetorical pauses.
How is the Flesch Reading Ease score calculated?
The Flesch Reading Ease algorithm evaluates average sentence length and syllable count per word. Scores above 60 indicate accessible, standard English for broad audiences, while scores below 50 reflect complex academic or legal prose.
Are my manuscripts, articles, or confidential speeches sent to any server?
No. Everything runs strictly in-browser memory on your local machine. Your text is completely private and never transmitted over the internet.
