In Step 2 of the story creation process, click the gear icon next to “Describe Your Story” to configure additional Advanced options.

The first setting lets you choose your "Book Size." The book sizes that are available are based on your plan level which you can learn more about here.

⚠️ If you change the book size after your book is completed, the current cover and illustrations will be removed and regenerated to fit the aspect ratio. Your story text and characters will stay the same.

Next choose your spread layout, with three options available: Single Image, Dual Image and Mixed.
Single Image: Displays one image per spread, ideal for full-focus illustrations or scenes where a single visual tells the story clearly.
Dual Image: Splits the spread into two images, allowing you to show contrasting scenes, before-and-after moments, or two related perspectives side by side.
Mixed: A flexible layout that combines both single and dual image spreads throughout your book for variety and dynamic storytelling.

⚠️ If you change the spread layout after your book is completed, the current illustrations will be removed and regenerated to fit the new layout. Your story text and characters will stay the same.

Choose how many sentences should show on each page.

Choose your text placement.
Fixed: The story text will remain in the same position on every page.
Smart Fit: The story text will no longer be anchored to the bottom of the page. Instead, it will be automatically resized and positioned in the most suitable location for each illustration.
