How to build a reading habit

How to build a reading habit: the short version

1. Pick an amount you could manage on a bad day. Ten pages or 15 minutes is enough. Ten pages a day finishes about 12 books a year.
2. Attach it to something you already do every day. "After I finish dinner, I will read ten pages" works better than "I'll read more."
3. Read in the same place, at the same point in your day. The fixed cue is what turns a decision into a habit.
4. Read books you want to read, and stop the ones you don't. People build stronger habits around things they enjoy.
5. Expect it to take about two months. If it still takes effort after four weeks, that's normal.
6. Don't start over after a missed day. One miss doesn't undo the habit. Read the next day.
7. Keep a record. A log or a streak shows you a pattern your memory won't.

The rest of this page is the evidence behind each step, and what the numbers add up to.

How long does it take to build a reading habit?

A reading habit takes about two months to become automatic for a typical person, and anywhere from under three weeks to most of a year for an individual. Those figures come from studies of other daily habits, such as drinking water, flossing and exercise. We haven't found a study that measures reading habits specifically.

The best-known study is by Phillippa Lally and colleagues at University College London, published in 2010. They asked 96 volunteers to repeat one eating, drinking or exercise behaviour every day, in a context they chose, such as "after breakfast", for 12 weeks. For the 39 people whose results could be modelled well, the behaviour took a median of 66 days to reach 95% of its peak automaticity. Individuals ranged from 18 to 254 days.

A 2024 systematic review of 20 studies and 2,601 participants, led by Ben Singh at the University of South Australia, found the same pattern. The four studies that reported a timeline gave medians of 59 to 66 days and means of 106 to 154 days, with individuals ranging from 4 to 335 days. The means sit well above the medians because a minority of people take much longer.

So plan for about two months before reading feels like something you do rather than something you decide to do, and don't read a slow start as failure.

Where does "21 days to form a habit" come from?

The 21-day figure comes from Maxwell Maltz, a plastic surgeon, who wrote in his 1960 book Psycho-Cybernetics that patients took about 21 days to get used to a new face. From that and similar observations, he concluded that "it requires a minimum of about 21 days for an old mental image to dissolve and a new one to jell."

He was describing how long people take to adjust to a change, not how long a new behaviour takes to become automatic, and he said "a minimum". In Phillippa Lally's 2010 study of habit formation, 18 days was the fastest anyone reached automaticity, and the median was more than three times as long.

How many minutes a day should you read?

There is no research-based minimum for adults. The amount that builds a habit is the amount you will repeat every day, because repetition in a consistent context is what the habit studies measured. Fifteen or 20 minutes is enough to finish well over a dozen books a year:

These figures assume the average adult reading speed for fiction, 260 words a minute (Brysbaert, 2019), 275 words a page and 300-page books, read every day. The reading goal calculator works it out for your own speed and books.

For comparison, Americans aged 15 and over averaged 16 minutes a day reading for personal interest in 2025, according to the Bureau of Labor Statistics. The typical American adult read 2 books that year. The reading statistics page has the details and the sources.

Is 10 pages a day enough?

Yes, 10 pages a day is enough to finish about 12 books a year if they're 300 pages long, or 18 if they're 200 pages. That's more than most Americans read: in a December 2025 YouGov poll, 19% of the US adults surveyed said they read ten or more books in 2025. At the average reading speed, ten pages takes about 11 minutes.

When and where should you read?

Read at the same point in your day, in the same place, and attach reading to something you already do. Every participant in Phillippa Lally's 2010 habit study tied their new behaviour to a context they had picked, such as "after breakfast", and the habit grew with repetition in that context.

The most practical tool from this research is an if-then plan, which psychologists call an implementation intention: "When this happens, I will do that." In a 2006 meta-analysis of 94 independent tests with more than 8,000 participants, Peter Gollwitzer and Paschal Sheeran found that making a plan like this had a medium-to-large effect on reaching a goal (d = 0.65), compared with only intending to. For reading, fill in the blanks:

After I [something I do every day], I will read [pages or minutes] in [a place].

For example: "After I get into bed, I will read ten pages before I pick up my phone." Or: "After I sit down on the train, I will read until my stop."

What about the time of day? A 2024 review of habit studies, led by Ben Singh, found that habits practised in the morning, and habits people chose for themselves, tended to be stronger. Those studies were about habits like flossing and exercise, though, and a reading slot you'll actually hit every day is worth more than a better one you'll skip.

What happens if you miss a day?

Missing one day doesn't break a reading habit. Phillippa Lally's 2010 study of how habits form found that "missing one opportunity to perform the behaviour did not materially affect the habit formation process." Consistency over weeks still counted: people who did the behaviour more consistently were more likely to show the steady rise in automaticity the researchers were measuring. A single miss didn't reset it.

The practical rule is to read the next day and treat the miss as a miss, not as a reason to start over. It's also why a streak that drops to zero after one missed day is harsher than the research: it counts a single miss as a restart.

Chaptify's streak is built with this in mind: missing a single day doesn't break it, so one busy day doesn't erase the progress you've already made. The aim is consistency over time, not perfection.

How do you read more instead of scrolling?

Pick the moment you usually reach for your phone and make reading the planned response to it. Americans aged 15 and over spent 2.6 hours a day watching TV in 2025 against 16 minutes reading, according to the Bureau of Labor Statistics, so for most people the time is already there. An if-then plan works here too: "When I get into bed, I will read before I open my phone."

The rest is about the order things come in. A book on the pillow, or an e-book app on the home screen where the social apps used to be, makes reading the first option rather than the one you have to remember.

Which books should you start with?

Start with books you expect to enjoy, and give yourself permission to stop one that isn't working. A 2024 review of habit research, led by Ben Singh, lists affective judgements, meaning how much people liked the behaviour, among the factors that significantly influenced how strong a habit became. A reading habit built on books you like has that working for it. A worthy book you dread opening works against it.

How do you track a reading habit?

Record each day you read, with the minutes or pages, and look back at the record once a week. Most surveys of reading ask people to remember a whole year of it. A record shows the days you actually read.

A notebook works, and so does a spreadsheet: how to track your reading has a free template and compares the options. Chaptify, the app we make, counts every day you read toward a streak and times each session, so the record builds itself while you read.

What a reading habit looks like for me

By Ellis Newton, co-founder of Chaptify

My reading habit is pretty simple: two chapters before bed. During the school year, I make time to read every night before I go to sleep. During the summer, I usually read in the morning instead. It might not sound like much, but that small, consistent routine has helped me get through some pretty big books. Most recently I finished Crime and Punishment and Emma, and I'm reading The Count of Monte Cristo now.

What has helped me stick with these books isn't trying to read every free moment I have, or completely replacing things like scrolling with reading. It's having a specific time when I know I'm going to read. Once it became part of my routine, it stopped feeling like something I had to convince myself to do. I also use Chaptify to time my reading sessions and keep track of my progress, which gives me a little extra accountability and makes it satisfying to see how far I've gotten. For me, the habit is less about reading a huge number of pages every day and more about showing up consistently.

I've applied the same idea to a lot of other parts of my life. Staying consistent in the gym has helped me build a physique I'm genuinely proud of, and staying consistent with studying has helped me reach grades I'm proud of. Even with my health, I've found that the small things I do consistently have a much bigger impact than what I do once in a while.

Reading has been the same for me. I don't think you need to read for hours every day to become a reader. You just need to make reading something you consistently come back to. That's the idea behind Chaptify: making it easier to build a reading habit by giving you a reason to show up every day.
