How Estimates Are Calculated
Estimates are based on the median reading speed of 214.5 minutes per 49,241 words. Your own pace may differ, but this provides a consistent baseline.

If the EPUB has no fixed print pagination, the tool starts with an estimated page count and lets you replace it with the page total shown by your own reader.

How the progress estimate works
The Reading Time tool estimates how long it will take to read a book from the catalog. It uses the book’s word count and the library’s median reading speed to give a rough estimate in minutes.
Keep in mind that these are estimates; individual reading speeds vary. Use them to plan your reading schedule or to compare books of different lengths before you start.
Length Categories
Books are grouped into four length categories: short (under 30,000 words), medium, long, and epic (over 100,000 words). Use these to gauge the scale of a title.
Book-Specific Estimates
Each book page shows its exact word count and estimated reading time. For example, 'The Little Skipper' is 15,362 words and takes about 67 minutes to read.
Planning a Page-a-Day Read
The Reading Tracker turns a chosen book into a simple daily plan. It records progress in pages, not minutes or sections. You set a current page, a total page count, and a daily goal. The tracker then estimates how many days remain. This works best when you have a specific book in mind, like "Ruth Fielding at Briarwood Hall; or, Solving the Campus Mystery — Context and Discussion" (id 293).
Setting Up Your Page Count
The tracker uses a default of 250 words per page to estimate the total pages. For "Ruth Fielding at Briarwood Hall" (46,333 words), that gives an initial estimate of ceil(46333 / 250) = 186 pages. You can replace that estimate with the page count from your own edition, which may differ.
The current page starts at 1, and you update it as you read. The daily goal defaults to 20 pages, but you can adjust it to whatever fits your schedule. For a 186-page book, 20 pages a day means about 10 days of reading.
Understanding the Estimates
The remaining time is proportional: if you are on page 50 of 186, you have 136 pages left. The estimated minutes are based on the book's reading time of 202 minutes, so the remaining time is 202 × 136 / 186, which is about 148 minutes. This is a rough guide, not a promise.
Finish days are calculated by dividing remaining pages by your daily goal. With 136 pages left and a 20-page goal, you would finish in ceil(136 / 20) = 7 days. If you change the goal to 10 pages, it becomes 14 days.
Tracking Progress Without Accounts
The tracker stores your progress in your browser's localStorage, so no account is needed. You can close the page and come back later — your current page and goal remain. This makes it easy to keep a reading log over days or weeks.
Keep in mind that the tracker does not record sections or minutes as progress. Only pages count. So if you read half a chapter, you must estimate how many pages that is. This keeps the system simple and consistent.
Using the Tracker with a Real Book
For "Ruth Fielding at Briarwood Hall," you might set a goal of 15 pages a day to finish in about 13 days. That is a comfortable pace for a 46,000-word book. The tracker helps you see if you are on track, and you can adjust the goal if life gets busy.
The tracker is a practical tool, not a judge. It simply shows you where you are and how much is left. That clarity can make a long book feel more manageable.
