The thickness of a one-million-word physical novel mainly depended on the plot, character description, story structure, and other factors. Different types and styles of novels would have different book thickness. Generally speaking, the thickness of a physical novel with a million words was between 2 cm and 10 cm. However, the specific thickness still needed to be calculated according to the actual situation. For example, if the plot of the novel was very compact, the character description was profound, and the story structure was complicated, then the thickness of the book might be relatively high; if the plot of the novel was relatively flat, the character description was simple, and the story structure was simple, then the thickness of the book might be relatively low.
