The page numbers on the document pages do not always match the page numbers below the page thumbnails. Pages are numbered with integers, starting with page 1 for the first page of the document. Because some PDFs may contain front matter, such as a copyright page and table of contents, their body pages may not follow the numbering shown in the Page Navigation toolbar.
You can number the pages in your document in a variety of ways. You can specify a different numbering style for a group of pages, such as 1, 2, 3, or i, ii, iii, or a, b, c. You can also customize the numbering system by adding a prefix. For example, the numbering for chapter 1 could be 1-1, 1-2, 1-3, and so on, and for chapter 2, it could be 2-1, 2-2, 2-3, and so on.
