Word Count to Reading Time and Speaking Time: The Numbers Behind the Estimate
October 21, 2026
Reading time is word count divided by reading speed. Research on adult silent reading of non-fiction puts the average near 238 words per minute, while comfortable speech runs around 130 to 160 words per minute. A 1,500-word article therefore takes about 6.3 minutes to read silently and 10 minutes to deliver aloud at 150 words per minute.

Divide the word count by the speed to get minutes. Use a lower speed for technical or dense material and a higher one for light reading. Presentations should also include time for pauses, slides, and questions.
| Word count | Silent reading (238 wpm) | Speaking (150 wpm) |
|---|---|---|
| 500 | 2.1 min | 3.3 min |
| 1,000 | 4.2 min | 6.7 min |
| 1,500 | 6.3 min | 10.0 min |
| 3,000 | 12.6 min | 20.0 min |
| 5,000 | 21.0 min | 33.3 min |
What Changes the Estimate
Reading speed varies between individuals, from under 150 wpm to over 400 for fast readers, and drops for unfamiliar topics, small screens, or second languages. Fiction is read faster than technical writing. Proofreading is slower, often around 200 wpm or below.
For speaking, a podcast host may talk at 150 to 170 wpm, while an audiobook narrator averages about 150 wpm. Slow, formal presentations run closer to 120 wpm.
Using It for Planning
For a 10-minute talk at 140 words per minute, aim for about 1,400 words, fewer if you plan to show slides or demos. For a blog post, many sites display reading time rounded to the nearest minute, so a 1,100-word article shows 5 minutes.
Use word count tools to monitor length while you write, and add a margin of about 10% when timing a speech, as nervousness often changes pace.
