If you are 30 and read one book a month, you have about 600 books left. At 40 it is about 490, at 60 about 280. That is how many books you can read in a lifetime at that pace, going by the latest US life table and the median length of a novel. Find your age and your pace below.

Before you look at the table: this number tends to be unpleasant for about five minutes. After that it makes quite a few things easier.

How many books can you read in a lifetime: the table by age

Find your age, then the column closest to how you read. Results are rounded to the nearest ten.

Your age Years ahead 4 books a year 12 books a year 24 books a year 52 books a year
20 59.2 240 710 1,420 3,080
25 54.5 220 650 1,310 2,830
30 49.8 200 600 1,190 2,590
35 45.2 180 540 1,080 2,350
40 40.6 160 490 970 2,110
45 36.1 140 430 870 1,880
50 31.7 130 380 760 1,650
55 27.4 110 330 660 1,420
60 23.3 90 280 560 1,210
65 19.4 80 230 470 1,010
70 15.7 60 190 380 820
75 12.3 50 150 290 640
80 9.2 40 110 220 480

These paces cost less time than they sound. Four books a year is about 4 minutes of reading a day. Twelve is 13 minutes. Twenty-four is 25 minutes, and a book a week is 55 minutes, roughly one episode of a series.

How we worked it out

The sum is simple: years ahead × books a year.

The years come from the US Social Security period life table for 2023, the one used in the 2026 Trustees Report. It lists men and women separately, so we took the average of the two: at exactly 30, that is 47.5 years for men and 52.1 for women. It is a population average and says nothing about any one person. Your genes, health and eyesight get more of a vote.

To turn books into minutes we assumed two things. A book is 368 pages, the median in our sample of 53 prize-winning novels. The pace is about 57 pages an hour: 238 words a minute from a 2019 meta-analysis, at 250 words a page. So one book takes about 6.5 hours.

Others have run a version of this sum. Literary Hub did it in 2017. In 2023 The Economist estimated that someone who reads from the age of seven will get through about 770 books, based on a panel of 1,500 Americans in which readers finished an average of 11 books a year. We are relying on ETX Studio’s write-up for that figure.

Is 600 books a lot or a little?

Depends where you stand.

15 mof shelf for 600 books
27%of US adults read more than 10 books in a year
129.9 mbooks counted by Google in 2010

At 2.5 centimetres each, 600 books fill about 15 metres of shelf (roughly 49 feet). They would fit in one good-sized room. A whole reading life in one room. Give that a moment.

On the other hand, a book a month already puts you ahead of most people. In a Gallup poll from December 2021, 27% of US adults had read more than ten books in the past year and 17% had read none.

Now the number that ends all ambition. In 2010, Google engineers counted 129,864,880 books in the world, treating different editions of one title as separate books. For each of your 600, that leaves about 220,000 you will never open. Nobody reads everything. You can stop trying and breathe out.

The best number in this article: 10 minutes a day

Here the maths gets kinder. Reading time comes in small pieces, and small pieces add up to a lot over decades.

Extra time a day More books a year More books if you are 30 More books if you are 60
5 minutes almost 5 about 240 about 110
10 minutes over 9 about 470 about 220
15 minutes 14 about 710 about 330
20 minutes 19 about 940 about 440
30 minutes 28 about 1,410 about 660

That assumes you read every single day, which nobody does. Pick up a book four days out of seven and 10 minutes gives you about 270 extra books instead of 470. Still worth having. The reading goal calculator shows what a plan like that means in pages, and how many books to read a year covers setting a goal.

Your to-read list at this scale

This is funny or frightening, depending on the length of your list.

To-read list Years at 12 books a year Share of what is left at 30 At 40 At 60
50 books about 4 8% 10% 18%
100 books about 8 17% 21% 36%
200 books about 17 33% 41% 72%

And meanwhile books you have never heard of will come out, and someone will recommend them over coffee. A long list is fine. It just works better as a menu than as a plan. Here is how to keep a TBR list that stays useful, and when you can’t choose, try the TBR picker.

What to do with this number

Four ideas, none of which involve reading more.

Give up on books without guilt

A book you are not enjoying will take several more hours and one of those 600 places. Fifty pages take less than an hour and are usually enough to tell. The other 300 are more than five hours that could go somewhere better. More on that in when to DNF a book.

Go back to your favourites

If places are limited, why read the same book twice? Because this number is not a score to push up. A favourite book can be a different book ten years later, and you a different reader. If that means 599 instead of 600, the world will cope.

Read what you feel like reading

Romance, manga, a beach thriller and Russian classics each take up one place on this shelf. Nobody will check your “100 books to read before you die” list at the end. Audiobooks count too, and for adults the research is fairly consistent.

Start with today’s five pages

If you are 60, you still have about 280 books ahead at a modest pace. If you haven’t finished a book in two years, the table starts today and doesn’t look back. Five pages count.

Track your pace in Talemi

Talemi is the reading tracker app we are building. You log the page you are on and your progress shows on the book’s spine on your shelf. A daily goal and stats show how much you really read, so you can find your column in the table without guessing. Day off? Your shelf isn’t going anywhere. See how Talemi works and join early access.

FAQ

How many books can you read in a lifetime? At a book a month, a 30-year-old has about 600 left, and at a book a week about 2,590. The Economist estimated about 770 over a whole life for American readers.

How many books does the average person read in a lifetime? There is no solid figure. The Economist’s 770 only covers people who read at all, and in its panel 46% had read no book that year.

Could you read 10,000 books? In theory. At 20, you would need about 170 books a year, roughly 3 hours of reading a day for about 59 years.

How many minutes a day does a book a month take? About 13 minutes a day, for a 368-page book at an average pace.

Do audiobooks count? In our sum, yes. What counts is the book you got to know, not whether you held it.

Does this table predict how long I will live? No. A life table is a population average based on mortality data, and this table is a bit of fun with numbers that may help you choose books.
