If you're using Layout Library, the page dimensions are:
- 550pt x 630pt for Book
- 1100pt x 630pt for Presentation
If you're using Fully Editable, these can differ and be set to custom so we suggest you add a shape panel and drag it to cover the full page, then look at the height and width in the right hand shape settings as this will be the size of the page.
If you need them in a different measurement metric, the below may help convert it for you!
