Paste text or enter a word or page count to calculate read time instantly. This free reading time calculator answers “how long will it take to read this?” with separate silent-reading, read-aloud, and audiobook estimates down to the second. It also works as a read time calculator, text to time calculator, time to read calculator, and reading time estimator without creating competing pages for the same intent.
At the 238 WPM non-fiction starting point, 100 words take about 26 seconds, 500 words take about 2 minutes 7 seconds, 1,000 words take about 4 minutes 13 seconds, 2,000 words take about 8 minutes 25 seconds, 5,000 words take about 21 minutes 1 second, and 10,000 words take about 42 minutes 1 second. Use the calculator for an exact text or a personal WPM.
Reading time in seconds equals word count divided by words per minute, multiplied by 60. The 238 WPM silent-reading baseline and 183 WPM oral-reading baseline come from Marc Brysbaert’s 2019 review and meta-analysis of 190 studies and 18,573 participants. VoiceBrief models audiobook narration separately at 150 WPM for 1x audio, 225 WPM at 1.5x, and 300 WPM at 2x. These are planning inputs, not guarantees about an individual reader or narrator.
The reverse planner uses the same formula in the other direction: available minutes multiplied by WPM equals the words that fit. For example, 10 minutes at 238 WPM fits about 2,380 words, or roughly 8 pages using the calculator’s 300-word page assumption.
Choose silent reading, read aloud, 1.5x audiobook, or 2x audiobook in the reverse planner. Actual time varies with text difficulty, familiarity, note-taking, pauses, headings, pronunciation, layout, and accessibility needs. Use a slower personal speed for technical first-pass reading and a faster speed only when your own comprehension remains acceptable.
The same page includes a free timed reading-speed test with an original passage and a comprehension check. Start the timer, read at a comfortable pace, stop when finished, and answer without looking back. The tool calculates words per minute locally in the browser. A correct answer lets you apply the measured WPM to the reading-time calculator; an incorrect answer prompts a retest because speed without understanding is not a useful planning baseline.
The result is one snapshot, not a standardized assessment. Reading pace changes with difficulty, familiarity, fatigue, and purpose. The measured WPM and comprehension answer stay in the current browser.
Libraries, course sites, publishers, and study-skills resources can add the responsive VoiceBrief calculator with the versioned public reading-time widget script. The widget has no cookies, analytics, or network requests after the script loads; pasted text stays in the visitor's browser. The versioned URL is stable and cacheable for long-lived embeds. Keep the visible VoiceBrief attribution when embedding it.
