How many pages in the biggest book roald dahl wrote?

It's difficult to definitively say which Roald Dahl book is the "biggest" in terms of pages.

Here's why:

* Page count varies by edition: Different publishers use different page sizes and formatting, making page counts inconsistent.

* No single metric: "Biggest" could refer to page count, word count, or even physical size.

However, some of Roald Dahl's longest books include:

* "The BFG": Often cited as one of his longer novels.

* "Charlie and the Chocolate Factory": Another popular choice for a longer book.

* "Matilda": While not as lengthy as some others, it's considered a substantial work.

To find the most accurate page count for a specific book, you should consult the edition you have.
