Insert page numbers in Word 2010 ("automatic pagination")
Our add header / footer tutorial goes in depth into options, including automatic pagination, for your Word 2010 documents. This tutorial goes straight to inserting page numbers.
Double-click inside the top margin of your open document, and Word opens the header in edit mode (double-click near the bottom of the page to add page numbers in the footer).
The cursor (insertion point) starts blinking, the "Header and Footer Tools / Design" tab will automatically be activated in the Ribbon: click on the "Page Number" dropdown.
The "Top of Page" and "Bottom of Page" menus include the same content for the header or the footer: pick a pagination scheme by clicking on it (notice that the menu includes a scrollbar). "More Page Numbers from Office.com" checks for available online templates.
With "Page Margins", Word will show page numbers alongside any edge of the sheet!
"Current Position" lets you insert the page number within your own formatting (e.g., you can insert spaces to offset this number, or include an image before it, etc.)
Click on "Format Page Numbers" to switch to letters or roman numerals, optionally including chapter numbers with headings, or (re-)starting page count at an arbitrary number.
"Remove Page Numbers" eliminates pagination, but keeps your header/footer intact.
Once you are done, hit Escape (Esc) to return to your document.
Tip: double-click in the header / footer area to edit your pagination settings after the fact.
