Why Fewer People Are Finishing the Books They Start

The average American starts around 12.6 books a year but finishes only about 5. And the reason isn't as simple as phones destroying everyone's attention span.

E-reader data shows that many readers decide whether to continue within the first 50–100 pages. Meanwhile, a 2025 study covering more than 236,000 people over two decades found a surprising pattern: fewer Americans are reading for pleasure, but those who still do are spending more time reading than they did twenty years ago.

The story isn't simply that we're becoming incapable of finishing books.

Reading appears to be splitting in two.

The Gap Between Starting and Finishing

Ask someone how many books they've started this year.

Then ask how many they've actually finished.

The numbers probably won't match.

A 2022 survey of 2,000 American adults found that 52% hadn't completed a book in the previous year, while nearly three in ten said they generally don't finish the books they start. Among those who do read, the average was about 12.6 books started versus roughly 5 completed.

That means a lot of books are being opened with good intentions and quietly abandoned.

There's even a name for it now:

DNF: Did Not Finish.

Once, leaving a book halfway through could feel like failure. Today, quitting has become increasingly normal.

But here's where the story gets interesting.

What Happens After We Open a Book?

Surveys tell us what people remember doing.

E-reader data can show what they actually did.

Jellybooks, which analyzes reading behavior from e-readers, found that fewer than half of tracked books are finished by most readers. Only around 5% are completed by three-quarters or more of the people who start them.

And readers tend to make the decision surprisingly early.

The critical point is often somewhere between page 50 and page 100.

Whatever makes someone abandon a book usually doesn't happen near the end.

It happens near the beginning.

Did You Know?

Jellybooks' engaged-reader data also shows a striking age difference: roughly 70% of tracked books were finished among readers over 45, compared with around 10% among readers under 25.

That's one company's reader panel, not a universal measure of all readers but the difference is striking.

Maybe It's Not an Attention-Span Problem

The obvious explanation is familiar:

Phones ruined our attention spans.

But the data doesn't fit that story neatly.

A 2025 study analyzed more than 236,000 respondents from the American Time Use Survey between 2003 and 2023. It confirmed that reading for pleasure has declined substantially.

But then researchers found something unexpected.

Among people who still read for pleasure, average daily reading time actually increased from about 1 hour 23 minutes in 2003 to roughly 1 hour 37 minutes in 2023.

If everyone's ability to concentrate were simply collapsing, you'd expect committed readers to be reading for less time too.

They're not.

Instead, the pattern looks more like polarization.

A smaller group is reading deeply.

A larger group is barely reading at all.

That is a very different story from "nobody can concentrate anymore."

We Also Learned That It's Okay to Quit

There's another shift happening alongside the numbers.

Readers are becoming more comfortable abandoning books.

Librarian Nancy Pearl famously suggested the Rule of 50: give a book 50 pages, and if it isn't working, put it down.

For older readers, she later suggested subtracting their age from 100 to determine how many pages to try, essentially recognizing that time itself becomes a more precious resource.

Pearl has acknowledged that the rule wasn't based on scientific research. It was, in her words, essentially a way of giving readers permission to stop reading something they weren't enjoying.

And perhaps that's part of the cultural shift.

Finishing every book is no longer automatically considered virtuous.

Time is limited. Books are not.

Perhaps the Problem Is the Menu

There's another possibility.

Maybe modern readers aren't simply distracted.

Maybe they're overwhelmed by choice.

Think about the average reader's environment today.

A recommendation appears on Instagram.

Another arrives through an algorithm.

A friend suggests three more.

Your "to-be-read" list grows.

Your bookshelf fills.

Your Kindle fills faster.

And suddenly, while reading one book, you're already thinking about the ten others waiting for you.

Psychologist Barry Schwartz's work on choice overload offers a useful lens here: when the number of options increases, satisfaction with the choice we make can decline because all the alternatives remain visible in our minds.

There isn't a dedicated study proving that choice overload causes people to abandon books.

But it's an intriguing possibility.

Perhaps the modern reader isn't struggling because there are too few good books.

Perhaps there are simply too many.

Knowlegic Perspective

It's tempting to tell a simple story:

People are distracted.

Phones have destroyed attention spans.

Nobody finishes anything anymore.

But the data tells us something more nuanced.

The people who continue reading for pleasure aren't necessarily reading less deeply.

They're reading more.

The bigger change appears to be happening in the size of the reading population itself.

And that leads to a more interesting question:

Why is the gap between people who read and people who don't becoming wider?

Maybe the future of reading isn't about everyone reading fewer books.

Maybe it's about fewer people reading and those who remain becoming even more committed to it.

Perhaps finishing a book was never the real achievement.

Choosing the right book to finish might be.

We now have more books, more recommendations, more reviews, more lists, and more ways to discover what everyone else is reading.

But attention remains finite.

So the challenge isn't necessarily to read more.

It may be to choose better, stay longer, and give one good book enough time to change your mind.

Because somewhere between the 12.6 books we start and the 5 we finish, there is a question worth asking:

What would happen if we stopped collecting books—and started giving them our full attention?

And if you made it all the way here, congratulations, you've already beaten the book-abandoning statistics. Now go finish something else.
