About using single-page and two-page master pages

You can create single-page or two-page master pages in Publisher. Commonly, you will choose which kind of master page to use depending on how you set up your publication. If you set up your publication to be viewed as two-page spreads, you should use two-page master pages. If you set up your publication to be viewed as single pages, you should use single-page master pages.

Note   If you are working on a Web publication, you can view only single pages and can use only single-page master pages.
