Word 2016 can not only automatically number your pages, but it also lets you place the page number just about anywhere on the page and in a variety of fun and useful formats. Heed these directions:
Click the Insert tab.
In the Header & Footer area, click the Page Number command button.
A menu drops down, showing various page-numbering options. The first three are locations: Top of Page, Bottom of Page, and Page Margins (the sides of the page).
Choose where to place the page numbers.
If you want your page numbers on the bottom of the page, choose the Bottom of Page option.
Pluck a page-numbering style from the list.
You see oodles of samples, so don't cut yourself short by not scrolling through the menu. You can even choose those famous page X of Y formats.
Dutifully, Word numbers each page in your document, starting with 1 on the first page, up to however many pages long the thing grows.
Here's the good part: If you delete a page, Word renumbers everything for you. Insert a page? Word renumbers everything for you again, automatically. As long as you insert the page number as described here, Word handles everything.
To change the page number format, simply choose a new one from the Page Number menu.
If you merely need to reference the current page number in your document's text, choose the Current Position item in Step 3. Word inserts the current page number at the insertion pointer's location.
The page numbers are placed in the document's header or footer.
Page numbers can be removed just as easily.
