How Many Books Does Bill Gates Read Each Year?
Gates reads around 50 books per year, a pace he has maintained for decades. In a 2021 Reddit AMA, Gates noted that on vacation he reads about three hours a day, which helps him work through a large volume of titles. During working weeks, he blocks at least one hour daily. According to his friend Bernie Noe, as documented in the 2019 Netflix documentary "Inside Bill's Brain," Gates reads roughly 150 pages per hour with about 90 percent retention — a rate that, combined with disciplined daily habits, makes a book-per-week pace achievable. The key, Gates has said, is protecting that reading time rather than treating it as optional.
The Gates Method: Notes, Concentration, and Finishing Every Book
Gates has four consistent rules. First, he only starts a book he intends to finish: "I refuse to stop reading a book in the middle, even if I don't like it," he told Time in 2017. Second, he takes handwritten notes: "I take tons of notes in the margins while I read." In his 2021 AMA he added that he takes notes on about 20 percent of books because it "takes at least 2x as much time," but "for a lot of books that is key to my learning." Third, he prefers physical books specifically because writing in margins is easier. Fourth, he emphasizes that concentration is non-negotiable: "When you're reading you have to be careful that you really are concentrating."
Think Weeks: Gates's Intensive Reading Retreats
Twice a year since the 1990s, Gates has taken solo "Think Weeks" at a secluded cabin, secluding himself for seven days to read books and research papers without meetings or visitors. As documented in "Inside Bill's Brain" (Netflix, 2019), Gates would sometimes read through a dozen or more books during a single Think Week, occasionally working 18-hour days. Gates has described Think Weeks as essential "CPU time" — time to think freely about complex problems. The practice exemplifies his belief that deep, focused reading without interruption produces qualitatively different insights than the same reading done in fragmented sessions.
What Bill Gates Reads: Genres and Subject Matter
The overwhelming majority of Gates's reading is nonfiction, centered on science, global health, energy, climate, history, and business — subjects that directly inform his philanthropic work. He has an affinity for authors who synthesize vast amounts of data into accessible arguments; Steven Pinker and Vaclav Smil are two he returns to. In a 2017 tweet he wrote: "I wait for new Vaclav Smil books the way some people wait for the next Star Wars movie." He reads some fiction, looking for characters who help him see the world differently. As he told Time in 2017: "Every book teaches me something new or helps me see things differently. Reading fuels a sense of curiosity about the world."
GatesNotes: Where Gates Shares What He Reads
Since at least 2010, Gates has maintained GatesNotes, his personal website where he publishes book reviews, year-end lists, and summer reading recommendations. The platform has made him one of the most influential individual book recommenders in the world. A high-profile example: in 2018, Gates called Hans Rosling's Factfulness "one of the most educational books I've ever read" and arranged free digital downloads for all U.S. college graduates that year. He posts reviews of nearly every major title he reads, letting readers trace his intellectual interests across more than a decade of lists covering science, biography, history, and policy.
What Everyday Readers Can Learn from the Gates Approach
The habits Gates describes are teachable. He blocks time rather than fitting reading in opportunistically. He reads with a pen in hand, which forces active engagement. He does not multitask while reading. He commits to finishing books even when they challenge his views. And when he wants to understand a topic deeply, he reads multiple books on the same subject before forming conclusions; former colleague Mike Slade observed that Gates routinely reads at least five books on a topic to reach a decisive insight. In 2022, Gates distilled this into advice for his younger self: "Read a lot and discover a skill you enjoy."
