Reading time or pages: which one should you track?

Time and pages measure different things. Pages count output. Time counts effort. When you have both you get a pace, which is the useful part.

Two different measurements

The two most common ways to track your reading are pages and time. Every reading app I have seen picks one and hides the other.

Both are useful. They measure different things.

Pages measure output. It is what you got done. It is how you finish a book.

Time measures effort. It is what you spent. It is how you fit reading into your day.

Pages alone

If you only track pages, your log looks like a productivity dashboard. Pages this week, pages this month, pages this year. Book count is a byproduct. It is clean and satisfying and it hides how long you actually sat with the book.

Two people can both do 100 pages a day. One did it in 40 minutes on the train. The other did it in three hours on a Sunday. Same output, completely different lives.

Time alone

If you only track time, the log looks more like a habit tracker. Minutes today, streak this week, hours this month. It is closer to the truth of what happens, but it says nothing about what you were doing with those minutes. Ten minutes of manga and ten minutes of Wittgenstein are not the same ten minutes.

Both together give you pace

Time plus pages gives you pace. Pages per minute. That is the number that actually says something about you as a reader today, with this book.

Once you have pace you can:

Predict how long a book will take at your current speed
Compare genres without lying to yourself
Notice when a book is dragging (your pace drops)
Notice when a session was unusually good (your pace jumps)

I have 64 sessions logged this year. The pace changes with the book. It changes with the day of the week. It changes over months. If I only tracked pages I would think I read faster on weekends. If I only tracked time I would think Sunday and Saturday were the same. Because I track both, I can see that Saturday sessions are almost twice as fast as Sunday sessions. Same person, same books, different attention.

The practical thing

If you have to pick one, pick time. Pages are easy to remember and can be filled in later. Time is not. Once a session is over you cannot remember how long you spent. Time has to be measured while it happens or it is lost.

If you can, track both. That is exactly what Lecturameter does. Start a session, read, stop. Enter the pages. You now have effort, output and pace, all three, without doing any math.

The point of tracking anything is that you learn something from the data. Track only pages and you learn how much. Track only time and you learn how often. Track both and you learn about yourself.
