Roald Dahl is generally credited with writing around 50–60 books, depending on what is counted, with most reliable children’s-literature and education sites giving a figure of about 49–50 published books in his lifetime, plus additional posthumous and repackaged works.

Why the numbers differ

Different sources give slightly different totals because they count different things.

  • Some only count his children’s books and novels , giving totals in the high teens to low twenties (for example, about 19–21 core “books” like Matilda , The BFG , etc.).
  • Others include short story collections, poetry, autobiographies, and adult fiction , which pushes the total toward roughly 49–50 distinct book-length works.
  • A few guides also add “inspired by” and repackaged titles (toddler books, activity books, creative-writing guides using his characters), leading to higher counts well above 60, though these are not all fully original works by Dahl.

Simple takeaway

For a quick, practical answer to “how many books did Roald Dahl write”:

  • A commonly cited figure for original books authored by him (children’s books, adult novels, short-story collections, autobiographies, and poetry) is around 49–50.
  • If you only mean famous children’s books like Charlie and the Chocolate Factory , The Witches , and Matilda , then it is around 20 main titles.
