Essential for reports and papers
Any document running more than a couple of pages benefits from page numbers, and using Word's automatic numbering means the numbers update themselves correctly whenever pages are added or removed -- no manual renumbering required.
Pairs well with a table of contents
Page numbers are most useful alongside a table of contents that references them, so readers can jump straight to the section they need instead of scrolling through the whole document.
Frequently Asked Questions
I want the cover page and table of contents excluded from numbering entirely.
Insert a section break to divide the document, then set the page numbering to restart from the section that begins your main body text -- that lets the cover and table of contents stay unnumbered.
Can I use Roman numerals instead of regular numbers?
Yes -- under "Page Number Format," you can change the number style from Arabic numerals to Roman numerals (i, ii, iii).
