Reading Time Calculator
Estimate how long it will take to read a piece of text or a given word count, at various reading speeds.
What this calculates
How long does it take to read this? Useful for planning study time, sizing up an article, or estimating how long an audiobook would be at speech speed. This calculator uses well-established reading-speed ranges and converts word count to minutes for slow, average, and fast readers.
Formula & how it works
Time (minutes) = word_count ÷ words_per_minute. Standard speeds: 150 wpm slow / 240 wpm average adult / 350 wpm fast / 500+ wpm trained speed-reader. Speaking pace averages 130–150 wpm — audiobook timings hover around there. For text with dense vocabulary or formulas, reduce speed by ~30 %.
Worked example
A 1,500-word blog post. At 240 wpm (average): 6.25 minutes. At 150 wpm (slow / careful): 10 minutes. As spoken audio at 140 wpm: 10.7 minutes. A 90,000-word novel takes ~6 hours at 240 wpm.
Frequently asked questions
How is reading speed measured?
Words per minute (wpm) of continuous reading with reasonable comprehension. Skimming is much faster but comprehension drops. Studies generally cap genuine comprehension at ~600 wpm even for trained readers.
Why do some speed-reading claims seem impossible?
Because they often are. Claims of 1,500+ wpm with full comprehension don't hold up in controlled testing. Eye-saccade physiology caps usable reading speed for any human at around 500–700 wpm with comprehension intact.
Does paste this into the calculator work for any language?
Word count is the input here. English averages ~5 characters per word; some languages (German) are denser, others (Chinese) use character counts entirely. Adjust by 10–20 % for languages with longer words.
How can I read faster?
Stop subvocalizing (the inner voice that 'reads aloud' in your head), widen your eye span, and skip back less. Apps like Spritz use rapid serial visual presentation to train this. Practice raises speed about 30–50 % within weeks.
