Add page numbers and page count in Docs
If you'd like to add page numbers to a document you're editing in Google Docs, click the Insert menu and mouse over Page number. From the Page number sub-menu, choose where you want the page numbers placed on the page: Top of page or Bottom of page.
To insert a page count, click the Insert menu and select Page count. If you've inserted page numbers, the page count will show at the top or bottom of the page, next to the page number. If you haven't inserted page numbers, the page count will be inserted where your cursor is placed in the document.
Page numbers and page count are useful together to tell document viewers where they are in your document. First insert page numbers, then page count. Then, go to the header or footer and type "of" in between the two numbers. If a viewer is on page two of a five page document, they'd see "2 of 5" at the top or bottom of the page.
To delete a page number, go into the header or footer of the document and delete the page numbers.
