Reading Speed Calculator
Divide the number of words you read by the minutes spent reading to calculate words per minute (WPM). Enter your own timed sample below. The calculator also estimates pages per hour and the reading time for a 250-page book, using an assumed 275 words per page.
Calculate your pace
Your reading speed
200 WPM estimated reading speed.
Roughly 44 pages per hour assuming 275 words per page.
A 250-page book would take about 344 minutes at this pace.

Read it. Recall it. Use it.
An original ReadSprint exercise based on James Clear’s two-minute rule excerpt. This is a short practice sample, not a full chapter summary or a validated reading assessment.
Make a new habit easy to begin by shrinking its opening action. Establish a repeatable start before adding difficulty.
How to measure your reading speed
- Choose a passage similar to what you want to read next. A familiar article and an unfamiliar technical chapter may produce different paces. Use a passage with a known word count; page count alone is not enough for an accurate WPM calculation.
- Start a timer when you begin reading. Read at a pace that lets you follow the argument. Stop at a clear boundary and record the words actually read, rather than the word count of an unfinished passage.
- Enter the word count and elapsed minutes. Convert seconds to a fraction of a minute: 30 seconds is 0.5 minutes, so 4 minutes 30 seconds becomes 4.5. Both inputs must be positive.
- Before looking back, write the passage's main claim and one supporting reason. Check them against the text. This is a practical self-check, not a standardized comprehension score; the calculator itself does not assess understanding.
- Repeat with another comparable passage if the first was interrupted or unusually easy. Keep the sample, conditions, and any pauses in your notes. Use a representative pace for planning instead of treating your fastest result as a target.
Worked example: 1,200 words in 6 minutes
The formula is WPM = words read ÷ minutes spent. For a 1,200-word passage read in 6 minutes, 1,200 ÷ 6 = 200 WPM. The calculator rounds the result to the nearest whole word per minute.
At the tool's assumed 275 words per page, 200 × 60 ÷ 275 is about 44 pages per hour. A hypothetical 250-page book contains 68,750 words under that assumption; 68,750 ÷ 200 rounds to 344 minutes, or about 5 hours 44 minutes. These are reading-only estimates, not a promise about a particular book.
| Words read | Elapsed time | Calculation | Reading speed |
|---|---|---|---|
| 600 | 3 minutes | 600 ÷ 3 | 200 WPM |
| 900 | 4.5 minutes | 900 ÷ 4.5 | 200 WPM |
| 1,200 | 8 minutes | 1,200 ÷ 8 | 150 WPM |
Use your pace to plan, then check what you understood
The 275-words-per-page conversion is a fixed planning assumption in this tool, not an average measured from your book. Layout, illustrations, footnotes, and edition can change the number of words on a page. If you know the text's word count, use the reading-time calculator for a more specific estimate. If you only have pages and a deadline, use the daily reading planner.
A WPM result describes this sample under these conditions. It cannot establish that you read faster than other people, predict performance in another language, or measure what you will remember later. Note-taking, rereading, breaks, and trying an idea add time beyond continuous reading.
Rayner and colleagues' review describes a trade-off between reading speed and accuracy. That research is a reason to check understanding when changing your pace; it does not validate this calculator or define a universal target. For a demanding section, make time to explain the idea and check the source before moving on.
Frequently asked questions
Is this a timed reading test?
No. You time your own passage and supply its word count and duration. The calculator divides those values; it does not run a timer, count the passage's words, or test comprehension.
Can I enter seconds or a partial minute?
Enter time in minutes, including decimals. Divide seconds by 60: 90 seconds is 1.5 minutes, and 4 minutes 30 seconds is 4.5 minutes.
Can I calculate WPM from pages read?
Only if you also know or estimate the words on those pages. Different editions and page layouts contain different word counts. The calculator's 275-words-per-page assumption is used for its planning estimates, not to measure your input passage.
Does a higher WPM mean I learned more?
No. The result measures pace, not comprehension, recall, or application. Explain the main idea without looking, compare your explanation with the source, and decide what you need to revisit.
Choose your next reading step
- Estimate reading time from words and WPM
