Estimate your reading time
200 words/min is the commonly used average for general reading. Your actual readers will vary - denser or more technical writing is read slower than this average.
Where the 200 words-per-minute figure comes from
200 words per minute is the most commonly cited average silent-reading speed for general adult readers, and it's the figure most publishing platforms use for their own "X min read" estimates. Real reading speed varies by reader and by how dense the writing is - technical or unfamiliar material gets read more slowly than casual prose, even by the same person.
This calculator lets you adjust the words-per-minute figure with slow/average/fast presets if 200 doesn't match your own audience or writing style, rather than locking you into one fixed assumption.
Questions
How many words per minute does the average person read?
200 words per minute is the commonly used average for general adult silent reading, and the figure most publishing platforms use for their own reading-time estimates.
Why would my readers read slower than 200 wpm?
Denser or more technical writing is read more slowly than casual prose, even by the same reader. If your content is unusually detailed or jargon-heavy, a lower words-per-minute figure will be more accurate.
Does reading time predict engagement?
No - reading time only measures length, not whether the content actually resonates. A short post can underperform a longer one depending on what's actually said and how it's structured.
How do I know what content format actually works for my audience?
NotesIQ's Content Type Breakdown classifies your Notes and shows which format (Personal Story, Question, List/Tips, Quote/Repost) your specific audience rewards, rather than guessing from length alone.
