Reading Time Calculator
Enter a word or page count and your reading speed to see how long a book will take, plus how many days at your own daily pace.
About this reading time calculator
Enter a book's total word count directly, or switch to page count and a words-per-page estimate if that's what you have handy — most novels average somewhere around 300 words per page, though trim size and font matter. Pick a reading speed (slow, average, or fast, in words per minute) or enter your own custom pace, and the calculator works out the total time to finish the whole book.
Set how many minutes you plan to read per day, and it also converts that total time into a day count at your own pace, with a simple row of session dots giving a quick visual sense of the commitment — useful for deciding whether a long book fits into a trip, a readathon, or just your regular routine before picking it up. For a very long book, the dot row caps out and switches to a simple "+N more days" note rather than drawing an unreasonably long strip.
Reading speed varies by content as much as by person: dense nonfiction, unfamiliar vocabulary, or a heavily footnoted text can run well under your usual pace, even if you're normally a fast reader. Treat the result here as a solid starting estimate rather than a stopwatch to hit — comprehension and enjoyment matter more than finishing on schedule.
Nothing you enter here is saved or uploaded; it's a simple one-time calculation that runs entirely in your browser, ready to reuse for the next book on your list.
Frequently asked questions
How many words are in an average page?
Around 300 words is a common estimate for a typical novel, though trim size, font, and margins all shift this. Adjust the words-per-page field if you have a more specific number for your book.
What reading speed should I use?
200 words per minute is a common average pace. If you know your own typical speed from experience, enter it directly with the Custom option for a more accurate estimate.
Why might a book take longer than the calculator says?
Reading speed varies by content as much as by person — dense nonfiction, unfamiliar vocabulary, or heavy footnoting can all slow you down well under your usual pace. Treat the estimate as a starting point.
What do the session dots represent?
Each dot is roughly one day of reading at your chosen daily minutes, giving a quick visual sense of how many sessions the whole book will take at that pace.
Is anything I enter saved?
No, this is a simple one-time calculation. Nothing is saved or uploaded anywhere.
