Running Header in Word Online: Add and Format One Easily

To add a running header in Word Online, open the document, choose Insert > Header & Footer > Header, select a layout, and type the text you want repeated at the top of your pages. Word for the web repeats a standard header throughout the document automatically. You will need an editable document and an internet connection; page numbers and first-page variations are optional.

What You’ll Need

A Microsoft account with access to Word for the web, and a web browser.
A document you can edit. If it is shared, you need editing permission rather than view-only access.
The header text you want to use, such as a report title, your surname, a chapter name, or a short running title. Decide whether it should appear on every page or whether the first page should be different.

Step-by-Step

Open the document in Word for the web. Sign in to Microsoft 365, open the file from OneDrive or SharePoint, or go to Word for the web and choose the document. Check that you can edit it. If the file opens in read-only mode, ask the owner for edit access or choose an available editing option before trying to change the header. Word for the web saves edits to an online file as you work, though it is sensible to wait for the saved status before closing the tab.
Open the header controls. Select the Insert tab on the ribbon. Choose Header & Footer, then choose Header. Depending on the ribbon layout or window width, you may need to open a menu to see these options. If the ribbon is simplified, expand it or use the relevant menu under Insert; do not type the header into the first line of the document body.
Choose a header layout. Select a built-in header style if Word presents layout choices. A simple, blank layout is usually best for a plain title or surname. Some styles include extra elements, such as a line or a page-number area. If the style inserts content you do not need, select that content and replace or delete it while the header is active. The header area is separate from the document text, even though it appears on the same page.
Enter the text that should repeat. Click in the header placeholder and type your wording. Keep it concise so it does not crowd the page or overlap with other header items. For example, a school paper might use Nguyen on the left and a short paper title on the right; a work report might use Quarterly Sales Review. Use the exact capitalization and spelling you want throughout the document, because editing this shared header changes it on every page that uses it.
Format the header text. Select the words in the header, then use the options on the Home tab to change the font, size, color, bolding, or alignment. You can also use the paragraph alignment controls to position text. A restrained style—often smaller than the main body text—keeps the header readable without competing with the document. Use the formatting controls while the cursor is in the header; otherwise, your changes may apply to body text instead.
Add a page number if you need one. With the header area active, open Insert > Page Numbers and choose a top-of-page option if available. Review the choices before selecting one, since some layouts add a number in a particular position or include other formatting. A page number is a field, not ordinary typed text, so it can update as pages are added or removed. If you only need a repeated title and no numbering, skip this step.
Choose whether the first page should match. Most documents use the same header on the title page and later pages. If you need a blank or different first-page header, look for the Different First Page option in the header and footer controls and turn it on, if that option is available in your Word for the web interface. Then edit the first-page header separately from the following-page header. Check the result carefully: enabling this option can make the first page look empty until you add content to its separate header area.
Exit the header and check the pages. Click in the document body, or use the available close-header control, to return to normal editing. Scroll through several pages and confirm that the header repeats, is aligned as intended, and does not collide with text. If the document is long, inspect a page near the beginning, one in the middle, and the final page. Wait for Word to finish saving, then reopen or preview the file if the header is important to a submission or print job.

A running header normally repeats automatically because it belongs to the page header area, not because the same words were copied onto each page. New pages that use the same document section inherit that header. If your document has section breaks, however, some sections can have separate headers; a change may not appear everywhere until you edit the relevant section or connect its header to the preceding section. If you are unsure whether the document has sections, check the pages after major layout changes rather than assuming every page uses one shared header.

Common Mistakes

Typing the header in the body. Text placed above the first paragraph is not a real header and will not repeat automatically. Use the header command and type in the distinct header area.
Adding the same words to every page manually. This creates extra editing work and can leave pages inconsistent when the document changes. Put the shared text in the header once instead.
Editing the wrong area. The header can be close to the top of the page, but it is separate from the body. If a font or alignment change affects your paragraph, undo it and click inside the header before applying the formatting again.
Assuming a first-page setting applies everywhere. A different-first-page option creates a separate first-page header. Adding text to one header area does not necessarily populate the other, so inspect both when you use that setting.
Using a long title or oversized type. A header that is too wide or tall can wrap, look crowded, or reduce usable page space. Shorten the wording or reduce its font size rather than inserting spaces to force it into position.
Expecting a header change in one section to update every section. Documents with section breaks may have independent headers. Check later sections if a header suddenly changes or disappears after a page-layout change.

Tips

Keep the wording short. Running titles work best when readers can identify the document quickly without taking attention away from the page. Follow any style guide or assignment instructions if one specifies exact wording, placement, font, or page numbering.
Use alignment controls rather than repeated spaces. Spaces can shift unpredictably when fonts, margins, or page sizes change. Use the ribbon’s alignment tools, or a header layout that places items where you want them.
Check the whole page, not just the header. A header can look fine by itself but feel too close to the first line of text. Review the page with body content visible and check that the header does not cover anything.
Think about print as well as the browser view. If the document will be printed or exported, inspect Word’s print preview before distributing it. Printer margins and page size can affect how close a header appears to the edge.
Use a page-number field instead of typing a number. A typed number stays the same on every page, while an inserted page number updates to match its page. If numbering must start at a particular value or follow a complex section scheme, the desktop Word app may offer more controls than the web interface.
Make a copy before a major redesign. This is especially useful in a shared document or a file with multiple sections. A copy makes it easier to compare the layout or recover the earlier version if the header settings become confusing.

Troubleshooting

The header does not repeat. First confirm that you inserted it through Insert > Header & Footer > Header, rather than typing at the top of the first page. Then check whether the later page belongs to another section or whether Different First Page is enabled. If the issue affects only pages after a section break, inspect that section’s header and its connection to the preceding section. Word for the web may not expose every advanced section control, so open the file in the desktop Word app if you need to change those settings.

The header option is missing or unavailable. Expand the ribbon or check the Insert tab’s menus. If the document is view-only, request editing permission. If it is protected or uses a format with limited editing support, save an editable copy if you have permission, or open it in the desktop app. Refreshing the browser can help with a temporary display issue, but wait for any unsaved changes to finish saving first.

The header is hidden while you work. Switch from a reading-focused view to an editing or page-layout view, if available, and scroll to the top of a page. The header can be less obvious when the document is zoomed out or displayed in a view that prioritizes reading. Use print preview to check how it appears on the page.

The text is too close to the page edge or overlaps the body. Reduce the header font size or shorten its text first. If you need to adjust its position or the page margins and cannot find the required controls in Word for the web, open the document in Word for Windows or Mac. Avoid inserting blank lines in the header as a spacing fix; they can change the header’s height and create inconsistent-looking pages.

Changes are not visible on another page. Make sure the file has finished saving, then check another page in the same section. Look for a different first-page header, a section break, or an independently formatted section. If changes still appear missing, reload the document only after confirming that the save has completed.

Frequently Asked Questions

What is a running header?
A running header is text or other content placed in the page header area and repeated across pages. It often identifies a document, chapter, author, or report.

Will Word Online repeat my header on every page automatically?
Yes. A standard header repeats on pages that share the same section and header settings. A different first-page setting or a section break can make some pages behave differently.

Can I put a page number and title in the same header?
Usually, yes. Add the header text, then use the page-number option for a top-of-page number. Check the layout afterward, because available number styles and placement controls can vary in Word for the web.

Can the first page have no header?
Look for Different First Page in the header controls and enable it if available. The first page then has its own header area, which you can leave blank while keeping a header on later pages.

Can I use different headers in different sections?
Yes, section breaks can allow different headers, but managing whether sections share headers can require controls that are easier to find in desktop Word. Check the affected section before changing the header so you do not alter other pages unintentionally.

Does Word for the web have the same header controls as desktop Word?
No. It supports common tasks such as adding and formatting a header, but some advanced layout and section controls may be limited or arranged differently. If an option you need is unavailable, choose Open in Desktop App when offered and continue in Word for Windows or Mac.
