Full width page without widget

Hi there,
in the page editor, you’ll find a box where you can specify the page layout without sidebars:

You can also choose a different layout for individual posts/pages. In the Post/Page editor, there is a Layout metabox at the bottom. Choose the preferred layout from here.

Does this help?
