The length of a storyboard depends on the type of project and how much detail the creator wants to include. There is no fixed number of pages or panels, but generally a storyboard is as long as it needs to be to cover all the major scenes or events of the story. For example, in storyboarding for writers, a storyboard for book might include one panel for each chapter or key scene. This means that for a novel with 20–30 chapters, the storyboard could also have around 20–30 panels. In film or animation, storyboards are often much longer, with dozens or even hundreds of panels, because every camera angle or shot is planned visually. When creating a storyboard for a book, the usual rule is that it should be long enough to show the complete structure—beginning, middle, and end—but short enough to remain clear and manageable. Writers often keep it flexible, so the length can expand or shrink as new ideas are added or removed.
