Quick answer: The Bible is generally named the best-selling book of all time, with estimates in the billions of copies distributed over the centuries. Among novels, Don Quixote (about 500 million claimed), The Little Prince and A Tale of Two Cities are often listed, and among series, Harry Potter leads with over 600 million copies. All such numbers are estimates.

No audited global ranking exists
Best-seller lists often change weekly, but all-time rankings are harder because records are incomplete. This guide pulls together the figures most often cited and explains how to read them.
Table of Contents
The Top of the List
Religious texts are by far the most distributed books in history, and the Bible is usually listed first, with estimates running into the billions of copies. Because the numbers include copies given away by organizations over many centuries, they are not comparable to retail sales of a modern novel. Many lists therefore separate religious and secular books.
Best-Selling Novels and Classics
| Book | Author | Claimed copies |
|---|---|---|
| Don Quixote | Miguel de Cervantes | about 500 million |
| A Tale of Two Cities | Charles Dickens | about 200 million |
| The Little Prince | Antoine de Saint-Exupery | 140 to 200 million |
| The Lord of the Rings | J.R.R. Tolkien | about 150 million |
| The Hobbit | J.R.R. Tolkien | about 100 million |
| Harry Potter and the Philosopher’s Stone | J.K. Rowling | about 120 million |
| The Alchemist | Paulo Coelho | 65 million or more |
Many of these figures come from publishers or reference works and are rounded. Some earlier sales were never fully recorded.
Best-Selling Series and Authors
Harry Potter is the best-selling book series, with more than 600 million copies sold worldwide, according to publishers. Agatha Christie is often listed as the best-selling novelist, with around two billion copies of her books sold in English and other languages, and Shakespeare and Danielle Steel are also on such lists. Authors such as Stephen King, James Patterson and Colleen Hoover sell in the tens or hundreds of millions.
Best-Selling Nonfiction
Alongside religious books, popular nonfiction includes The Diary of a Young Girl by Anne Frank, with tens of millions of copies, Dr. Spock’s Baby and Child Care, and cookbooks such as Joy of Cooking. Self-help classics like Think and Grow Rich and Rich Dad Poor Dad have also sold tens of millions.
Why the Numbers Disagree
Sales figures are usually self-reported, rounded and sometimes include different editions, translations or box sets. Some count copies printed, not sold. Others mix print, ebook and audio. A fair comparison needs the same method, which is rarely available for books from different eras.
Where to Find Current Best-Seller Lists
For up-to-date weekly rankings, check The New York Times Best Sellers, USA Today and Publishers Weekly in the US, or the Sunday Times list in the UK. You can browse top titles on Amazon too. These lists reflect recent sales, not all-time ones.
How to Read Sales Claims Critically
Phrases like over 100 million copies sold appear on covers and in press releases, but they are not always independently checked. Some counts combine translations or include copies given away. Others include box sets, so one purchase counts as several books. When you see a big number, ask who reported it and what it includes. Reference works like Guinness World Records and publisher statements are useful, but should be treated as estimates.
Best-Sellers by Decade
Best-seller lists reflect their time. In the 1990s, thrillers and legal dramas ruled. The 2000s brought Harry Potter, The Da Vinci Code and Twilight. The 2010s saw The Hunger Games, Gone Girl and a boom in young adult fiction. The 2020s have had a surge in romance and romantasy, partly driven by social media communities. Looking at these trends can help you see what readers want and what might come next.
Where Audiobooks and E-Books Fit
Modern best-seller counts increasingly include digital formats. Audiobooks are among the fastest-growing segments, and e-books account for a significant share of fiction sales. A book that does well in one format may not top print lists, so check which formats are counted before you compare. Services like Audible also publish their own popularity lists.
How to Explore the Best-Sellers Yourself
A fun way to use these lists is to read your way through them. Pick one title from each category: a classic, a children’s favorite, a modern series opener and a nonfiction hit. Keep a simple list in a notebook or a reading app, rate each book and compare your taste with the crowd. You may find that some of the most popular books are not to your liking, and that is fine. Reading widely helps you understand why certain stories connect with so many people, and gives you great material for book club conversations.
