About this tool
This page does two jobs. First, it measures how fast you read: press Start, read a short passage at your normal pace, press Done, and you get your words per minute. Second, it turns that number into a plan: enter a book's length and the calculator tells you how many hours and minutes it will take, and, if you say how much time you can read each day, how many days that is and the date you would finish.
Everything runs in your browser. The passage, the timer and the sums stay on your device, and nothing is uploaded. The passage was written for this page, so it is not a famous text you may already know.
How it works
The test counts the words in the passage and divides by the time between Start and Done. That gives words per minute. The three questions afterwards are a sanity check: a speed means little if you took in none of it.
The book calculator multiplies pages by words per page, or takes a word count directly, then divides by your words per minute. If you took the test, your result is filled in for you; otherwise it starts at 238, a commonly cited average. Change any input and the answer updates straight away.
Words per page is the least certain input. As a rough guide, mass-market paperbacks are often around 250 to 300 words a page, trade paperbacks about 300, and dense hardcovers 350 to 400 or more. These are rough averages, and a book with wide margins or lots of dialogue will fall below them. If the publisher or an ebook store lists a word count, use that instead.
What is a normal reading speed?
A 2019 meta-analysis by Marc Brysbaert pooled many earlier studies and put average silent reading of non-fiction at about 238 words per minute, and fiction at about 260. Treat those as averages, not targets. Studies disagree because they test different people, texts and tasks: reading a simple story for pleasure is not the same as reading a technical report for a quiz, and a short timed test on a screen is not the same as an evening with a novel.
For that reason, the bands in this tool are rough. Roughly, under 150 words per minute is slow and careful, 200 to 300 is typical for an adult, and 400 or more usually means fast skimming. Your result on one passage, on one day, is a snapshot.
Why speed-reading claims fall short
Courses and apps often promise speeds of 1,000 words per minute or more. Reviews of the research on reading, including a widely cited 2016 review by Keith Rayner and colleagues, find that the faster you push beyond roughly 500 words per minute, the more you trade away comprehension. You are not reading faster; you are reading less of the text.
That does not make skimming useless. Skimming is the right tool for deciding whether a book is worth your time or for finding one fact. It is just not a substitute for reading when you want to understand and remember.
Reading more without reading faster
For most people the limit is time and habit, not speed. At 250 words per minute, twenty minutes a day is about 5,000 words, and over a year that adds up to many books. The calculator makes this concrete: put in a 300-page paperback and 20 minutes a day, and see the finish date.
- Attach reading to something you already do. A fixed slot, such as before bed or on the commute, beats good intentions.
- Keep a book within reach. A paperback in your bag fills small gaps that a phone would otherwise eat.
- Stop books you are not enjoying. A book you dread is a book that stops your habit.
- Vary the pace. Slow down for dense passages and let easy ones go quickly.
Planning a reading list or challenge
If you are setting a goal such as twelve books this year, run the calculator for each title on your list and add up the hours. Dividing the total by 365 shows the daily minutes you need, which is often smaller than people expect. It also helps you mix lengths: a few short books keep momentum while a long one runs in the background.
Planning is easier when you know what you own. A scan-and-search catalogue can show you what is already on your shelves before you buy another copy; Codexia is one way to keep that catalogue on your phone. For more book tools, see the books tools hub, or browse all free tools.
Frequently asked questions
What is the average reading speed for an adult?
A 2019 meta-analysis by Marc Brysbaert, covering many studies, put average silent reading of non-fiction at about 238 words per minute and fiction at about 260. Individual readers vary a lot, and 200 to 300 is a sensible typical range.
Is a higher reading speed always better?
No. Faster is only better if you understand and remember what you read. Light fiction you are enjoying can be read quickly, while a dense argument or a textbook chapter rewards a slower pace. Match your speed to the text and your purpose.
Can speed-reading courses really double my speed without losing comprehension?
The research does not support that. Reading well beyond roughly 500 words per minute usually means skipping or skimming, and comprehension drops as speed rises. You can get a little faster by reading more often and by cutting distractions, but there is no shortcut to dramatic gains.
How many words are on a page of a book?
It depends on the format. Mass-market paperbacks often run about 250 to 300 words a page, trade paperbacks around 300, and dense hardcovers 350 to 400 or more. These are rough averages, so use the word count if you know it.
Why does the calculator suggest 238 words per minute?
It is the commonly cited average for silent reading of non-fiction from the 2019 Brysbaert meta-analysis, so it is a reasonable starting point. If you take the reading speed test, the calculator uses your own result instead.
Is my text or result sent anywhere?
No. The passage, the timer and the book calculator all run in your browser. Nothing you type or measure is uploaded, stored on a server or tracked by this tool.
