Five different layouts can be set up for any page:
- One column layout: the content has full width
- Two-column layout with left sidebar
- Two-column layout with right sidebar
- Three-column layout with left and right sidebars
- Three-column layout with two sidebars on the right
First set the default layout in the customizer, it will be the default for all pages and posts. Then you can set a different layout for every page in the right side of the editor.
