How to use

  1. 1 Choose mode: Measure (time yourself reading a passage) or Estimate (how long will this book take).
  2. 2 For Measure: enter how many words you read and the elapsed time (minutes and seconds). Use a known-length passage from a book or article.
  3. 3 For Estimate: enter the book length in words. Average novel: 80,000 words. Average non-fiction book: 65,000 words. Long literary fiction: 100,000+ words.
  4. 4 Enter your WPM (use Measure mode first, or use the average 250 WPM).
  5. 5 Click Calculate to see total reading time and how many days at 30, 60, or 120 minutes of reading per day.

FAQ

Q What is the average reading speed for adults?

238 WPM for non-fiction and 260 WPM for fiction in English, per Brysbaert's 2019 meta-analysis covering 190 studies. The popular "average is 200 WPM" figure underestimates — that range is typical for slower readers or technical material requiring careful reading.

Q How can I improve my reading speed?

(1) Read 30+ minutes daily — sheer volume builds speed naturally. (2) Reduce subvocalization (silently mouthing words) with finger-tracking practice. (3) Don't re-read words — most regression hurts speed without helping comprehension. (4) Skim chapter intros and conclusions to map content before deep reading. Realistic improvement: 50-100 WPM in 4-6 weeks of focused practice.

Q Is speed reading real?

Genuine 600-800 WPM with good comprehension is achievable for highly trained readers on familiar material. Claims of 1,000-2,000+ WPM with full comprehension are not supported by cognitive science (Rayner 2016 review in Psychological Science in the Public Interest). What's called "speed reading" beyond ~500 WPM is usually skimming with reduced comprehension.

Q How long does it take to read a typical novel?

About 5-6 hours at the 250 WPM average, for an 80,000-word standard novel. The Hobbit (95K words): ~6.5 hours. 1984 (89K): ~6 hours. Long literary fiction like Anna Karenina (350K words): ~24 hours. Audiobooks at 1.5× speed reach similar pace; at 2× they're faster than most reading.

Q How many books can I read per year?

At 30 minutes daily and 250 WPM, you read about 4.5 million words/year — roughly 56 average novels. The Pew Research Center finds average US adults read 12 books/year. Bumping daily reading to 60 minutes doubles to 100+ books/year. Most "I can't read more" claims are time-allocation rather than speed-related.

Q Does reading on screen affect speed?

Slightly, in most studies. Screen reading is typically 5-15% slower than print, partly due to lower contrast, blue light, and the reader's tendency to skim digital content. E-ink displays (Kindle) show smaller speed differences than backlit screens. For long-form reading, many readers prefer print or e-ink.

Q What's the relationship between reading speed and comprehension?

Roughly inverse beyond ~400 WPM. Reading at your natural pace with full attention typically yields 70-80% comprehension. Doubling speed to 800+ WPM commonly drops comprehension to 30-50%. The trade-off depends on material — leisure fiction tolerates speed loss; technical or argument-heavy material requires slower reading for retention.

Q Should I track my reading speed?

Once or twice to know your baseline is useful. Daily tracking of WPM tends to make reading anxious and joyless, defeating the purpose. The more important metric is books finished per month and what you actually retain. Use this calculator periodically to verify improvement, not as an ongoing habit.
