Frequently asked questions
How is reading time calculated?
It divides the word count by an average reading speed (around 200–250 words per minute), so a 1,000-word piece takes about 4–5 minutes.
Can I change the reading speed?
Yes — adjust the words-per-minute to match your audience; children and technical readers are slower, skim-readers faster.
What reading speed should I use?
Average adults read 200–250 wpm; skimming is faster, careful study slower.
