How to Add an MLA Header in Word (Step by Step)

To add an MLA header in Word, insert an automatic page number at the top right of the page, then type your last name and a space before it. Word will repeat the surname and update the page number throughout the document. Before you start, check whether your instructor has any special instructions; MLA papers generally use a surname followed by a page number in the upper-right corner, with no comma or label.

What You’ll Need

A document open in Microsoft Word for Microsoft 365 on Windows. The steps are similar in Word for Mac, with a note where the menus may differ.
Your surname, typed exactly as it should appear on the paper.
Your instructor’s formatting requirements, if they differ from standard MLA setup.

Step-by-Step

Open the document and check the page layout. Open the paper in Word and confirm that you are editing the right file. Standard MLA page setup uses one-inch margins. On Windows, you can check these under Layout > Margins; choose Normal if your instructor has not specified something else. The running header is separate from the first-page heading, which usually lists your name, instructor, course, and date at the left side of the page. Do not put that information in the header.
Go to the page-number controls. On the ribbon, select Insert > Page Number. In Word for Mac, use Insert > Page Number as well; depending on the build, it may open a dialog or a menu with position and alignment choices. Choose a top-of-page option. A page number inserted through this command is a field, so Word can change it automatically on later pages.
Choose the right-aligned top position. In Word for Windows, select Top of Page > Plain Number 3. This layout places the number at the top right. If your Word version shows different previews or names, choose the simple top-of-page design aligned to the right, not a decorative style or a bottom-of-page number. On Mac, choose the equivalent top position and right alignment in the Page Number menu or dialog.
Put the cursor before the page number. Word opens the header area and inserts the number field. Click immediately to the left of the number, or use the left arrow key until the insertion point is before it. Take care not to select the number itself. The number may have a light gray background on screen; this is field shading and does not print.
Type your surname and a space. Enter your last name, then press the spacebar once so it reads, for example, Garcia 1. Keep the surname and number on the same line. Do not add a comma, colon, dash, the word Page, or a first initial unless your instructor specifically asks for a different style. If your surname includes a hyphen or more than one word, use the name form your instructor expects.
Check the font and alignment. The header should be simple and consistent with the paper. Select the surname and number only if you need to adjust their font, size, or style; use the font and size required for your assignment. The number should remain at the right edge, with the surname directly before it. Avoid changing the paragraph alignment after choosing the right-aligned page-number layout, since that can shift the whole header to the left.
Close the header and inspect the first page. On Windows, choose Header & Footer > Close Header and Footer, or double-click in the main body of the page. On Mac, use the Close Header and Footer control if shown, or double-click in the document text. Confirm that the separate first-page heading remains in the body of the paper and that the running header is above it, not mixed into the heading.
Check a later page and save. Scroll to page two and at least one later page. Each should show the same surname with the correct, automatically increasing number in the top-right corner. If the header is correct, save the document. The number on the first page is normally 1 unless your instructor has given different instructions or the document includes a preceding section.

Common Mistakes

Typing the number instead of inserting a page-number field. If you type a 1 yourself, Word will repeat that same character in the header on every page. Use Insert > Page Number so Word creates a field that increments automatically.

Putting the running header in the body text. The header belongs in Word’s header area, not in the first line of the paper. Typing it into the body can make it appear only once and can disrupt the spacing of the first-page heading. Double-click in the top margin to tell whether you are editing the header; Word will display a header boundary and a contextual header tab.

Adding extra punctuation or a label. Standard MLA running headers normally show the surname and page number, such as Garcia 2, without a comma or the word Page. Follow your instructor’s specific rules if they ask for a variation.

Making the first page different by accident. Word can suppress the first-page header when Different First Page is selected. That setting is useful only when your assignment calls for a different first page. Otherwise, leave it unchecked so the surname and page number appear consistently.

Confusing the header with a title page. MLA papers generally do not need a separate title page unless the instructor requests one. The running header is still used with the regular first-page heading; it does not replace the heading or the paper’s title.

Tips

Use Word’s built-in page-number field even if the paper is only a few pages long. It saves time when you insert or remove paragraphs, because the page numbers adjust without manual edits. If you later add a title page or divide the paper into sections, check the numbering again rather than assuming the field settings stayed appropriate.

Keep the header plain. MLA formatting is not improved by adding a border, color, bold styling, a running title, or extra spaces between the surname and number. A single space is enough. If the surname and number look far apart, first check that the paragraph is right-aligned and that no tabs or extra spaces were inserted.

For a normal paper, Word’s default header position is usually suitable. Standard MLA setup places the header about one-half inch from the top of the page. If it appears too high or low, open the header and look for the position control on the contextual Header & Footer tab. Change the header-from-top measurement only if needed, and keep it consistent across pages. Avoid dragging the header boundary by eye, because small mouse movements can create inconsistent spacing.

Make a final visual check in Print Layout or Print Preview. The header may look close to the top edge on screen, but the preview helps you confirm it sits inside the page margins and does not overlap the body text. Also follow any course-specific template or instructions when they conflict with general MLA conventions.

Troubleshooting

The same number appears on every page. The number may have been typed as ordinary text rather than inserted as a field. Double-click the header, remove the manually typed number, and insert one through Insert > Page Number > Top of Page. Then place the cursor before the field and type the surname plus one space. Check page two to confirm that the value increments.

The header is missing from page one. Double-click the header area on the first page and look for Different First Page on the Header & Footer tab. Clear the checkbox if the first page should match the rest. If the instructor wants no number on page one, leave the option selected and make sure the later pages still have the correct header.

The number starts at the wrong value. A document may contain a section break or inherited numbering settings. Click in the affected section’s header, open Insert > Page Number > Format Page Numbers, and review whether numbering is set to continue from the previous section or start at a chosen value. For a standard paper that begins on page one, set the first page of the paper to start at 1. If sections are linked, changing one can affect another, so inspect each section after making a change.

The surname and number are on the left, or the header shifted. Reinsert a right-aligned top-of-page number style, or select the header paragraph and choose right alignment from Home > Paragraph > Align Right. Remove any tabs or repeated spaces between the surname and field. Avoid pressing Tab repeatedly to push content across the line; alignment controls are more reliable.

The number looks gray or disappears when you click away. A light gray background often marks a Word field and is not printed. Use Print Preview to check the actual result. If the number vanishes entirely, confirm that you did not delete the field while editing and that the header is not hidden by a first-page or section setting.

Frequently Asked Questions

Should an MLA header include my first name?
Usually, no. The running header normally uses your surname followed by the page number. Your full name belongs in the first-page heading unless your instructor specifies another format.

Does the first page get a page number in MLA?
Usually, yes. The first page normally shows your surname and page number just like the following pages. Use Different First Page only when the assignment instructions call for a different first page.

Should I type the page number myself?
No. Insert it with Word’s Page Number command so it is a live field and updates automatically when the document changes.

Where should the MLA header sit?
It belongs in the upper-right header area, typically about one-half inch from the top of the page. Keep it clear of the body text and consistent across the document.

Do I need a separate title page?
Not usually. MLA papers commonly use a first-page heading and the paper’s title in the body. Add a separate title page only if your instructor or assignment directions require one.

Will the steps work in Word for Mac?
Yes. Use Insert > Page Number and choose a top-of-page, right-aligned option. Some controls appear in a dialog rather than the same Windows-style dropdown, but the goal is the same: a surname followed by Word’s automatic page-number field.
