How to use it
Using the reading time calculator
- 01
Count the words
Paste into the word counter or read the count from your editor.
- 02
Pick a realistic speed
Keep 238 for casual reading; drop toward 150 for dense material.
- 03
Plan the time block
Round up and add slack for notes or re-reads of tricky passages.
Good to know
Where 238 comes from
Marc Brysbaert’s 2019 meta-analysis pooled hundreds of studies and landed on 238 wpm for silent English reading; a far sturdier figure than the folk 200–250 range. It is now the standard default for reading-time estimates.
Content type shifts everything
Skimmable listicles fly; legal contracts crawl. Readers self-adjust speed to difficulty, which is why a manual override beats any universal constant when stakes are real; billable hours, exam prep, podcast scripts.
Why blogs show “x min read”
Medium popularized the badge and engagement followed: telling readers the cost upfront reduces bounce. The convention uses roughly the same arithmetic as this calculator, usually rounded to whole minutes.
How it's calculated
The math behind this calculator
Minutes = word count ÷ reading speed (wpm)Divide the word count by reading speed in words per minute. The default of 238 wpm comes from a large 2019 meta-analysis of silent reading rates in English; slow proofreaders run near 150 wpm while speed readers exceed 400.
Assumptions & limitations
- Average adult silent reading in English at about 238 wpm unless customized.
- Technical, dense or foreign-language text reads slower.
- Formatting, images and headings are ignored; pure prose pace.
Worked example
A 1,200-word article takes the average reader just over five minutes at 238 wpm.
FAQ
Frequently asked questions
- Is reading speed different for audiobooks?
- Narration averages near 150–160 wpm, well below silent reading; a “6 minute read” becomes roughly 8 minutes listened.
- Does this work for children?
- Younger readers are slower: around 150–180 wpm mid-elementary, rising toward adult speeds in the teens. Enter a lower wpm for honest estimates.
- How do I count words first?
- Paste the full text into our word counter; it reports words, characters, sentences and paragraphs together.
- Why does my e-reader disagree?
- Apps estimate from screenfuls and fonts rather than word counts; small differences of a minute are normal.
