Estimated Reading Time
Based on the book's word count and a typical reading speed, this is the number of minutes you might expect to spend reading the entire text.

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 Insights page provides a closer look at a book's reading metrics. You can see the estimated reading time, the number of text sections, and the average sentence length, which together give a picture of the reading experience.
These figures are estimates, not guarantees. Your actual reading time will depend on your own pace and how carefully you read. Still, they can help you decide whether a book fits your schedule.
Text Sections
The number of sections or chapters in the book. This can give you a sense of how the book is organized and how it might divide into reading sessions.
Average Sentence Length
The average number of words per sentence in the book. A lower average suggests shorter, punchier sentences, while a higher average indicates longer, more complex prose.
Turning Pages into a Plan: Using the Reading Tracker
The Reading Tracker is built around a simple idea: progress is measured in pages, not in time or sections. You set a daily page goal, record your current page, and the tool calculates how many days remain. This page-based approach works with any edition, because you can adjust the total page count to match the copy you are reading.
Setting Up Your Page Count
When you start a book, the tracker estimates the total pages using a standard of 250 words per page. For Night and Day — A Closer Reading, with 173,833 words, that yields an initial estimate of about 696 pages. If your own edition has a different page count — perhaps due to larger type or added introductions — you can replace the total with the number shown in your reading app or physical book. This flexibility ensures the tracker remains accurate to your copy.
The current page is the only other field you need to update. As you read, you enter the page you have reached, and the tracker recalculates your remaining time and finish date. Because the data is stored in your browser's localStorage, your progress persists between visits without requiring an account.
Daily Goals and Estimated Finish
The default daily goal is 20 pages, but you can set it to whatever is sustainable for you. The tracker then estimates the number of days to completion by dividing the remaining pages by your daily goal. For Night and Day, if you have 600 pages left and read 20 pages a day, you are looking at 30 days. If you increase your goal to 30 pages, that drops to 20 days. The calculation is straightforward and helps you plan around your schedule.
Estimated remaining time is also shown in minutes, proportional to the book's total estimated reading time. This can be a useful cross-check: if you know you have a two-hour flight, you can see whether the remaining pages fit. The tracker does not record sections or minutes as progress — only pages — so you always know exactly where you stand.
Why Pages, Not Chapters?
Pages are a universal measure across editions, whereas chapters vary in length and number. A book like Night and Day has 35 text sections, but those sections may span many pages each. Tracking by page keeps your progress consistent, regardless of how the book is divided. It also makes it easy to compare your pace across different books, since you are always measuring the same unit.
The tracker's simplicity is its strength. It does not require you to estimate time spent reading or count sections; it just asks for a page number. That makes it easy to maintain, even if you only update it once a day. For long novels, this steady, page-based approach can turn a daunting project into a manageable series of daily steps.
