How to Change Margins in Microsoft Word

Word’s margin controls sit under Layout > Margins: pick a built-in preset like Normal, Narrow, or Wide for a one-click change, or open Custom Margins to type exact top, bottom, left, and right measurements. Every margin change also asks where it applies — the whole document, just the current section, or everything from the cursor forward — so one file can hold both a wide title page and a narrower body. If the whole Margins button is grayed out, the file is almost always protected — open Review > Restrict Editing, choose Stop Protection, and the presets come back to life.

Use a built-in margin preset#

Open the Layout tab and click Margins. Word shows a gallery of ready-made options with their measurements listed right in the menu, and clicking one applies it immediately — no dialog box, no confirmation. If the document has more than one section, the preset applies only to the section your cursor is sitting in.

Preset	Top / bottom	Left / right	Typical use
Normal	1”	1”	Word’s default for most documents
Narrow	0.5”	0.5”	Fitting more text on each page
Moderate	1”	0.75”	Reports and printed handouts
Wide	1”	2”	Notes, annotations, or generous side space
Mirrored	1”	inside/outside margins swap per page	Double-sided printing and booklets

Set custom margins for exact measurements#

None of the presets fit every requirement — an academic paper asking for 1.25 inches, or a résumé template that needs 0.9 inches. For that, go to Layout > Margins > Custom Margins. That opens the Page Setup dialog on its Margins tab, where you type separate values for Top, Bottom, Left, and Right (add a Gutter value too if the document will be bound). Word measures in inches by default in the US; switch that unit in File > Options > Advanced, under Display > “Show measurements in units of,” if you’d rather work in centimeters or points.

The same Page Setup dialog has a Layout tab for a related but different setting — how far the header and footer text sits from the page edge — which is worth checking if you’re also placing a logo or page number when you add a header in Word; that distance is independent of the body margin you just set. If you want your custom numbers to stick for every new document, not just this one, click Set As Default in the bottom-left corner of the dialog. Word warns that this rewrites the Normal template, and the new default takes effect the next time you open Word.

Apply margins to the whole document vs. one section#

At the bottom of the Custom Margins dialog is an Apply to dropdown, and it’s the setting people miss most often. It controls how far the change reaches:

Apply to option	What it affects
Whole document	Every page, regardless of section breaks
This point forward	Everything from the cursor’s current position to the end of the file
This section	Only the section break the cursor is currently inside (appears only if the document has section breaks)
Selected text	Only whatever you’ve highlighted, replacing “This point forward” when text is selected

To give one part of a document its own margins — a landscape appendix, a wider-margin cover sheet — you need a section break there first (Layout > Breaks > Next Page, or another break type), then reopen Custom Margins with the cursor inside that section and choose “This section.” Without a break, Word has nothing to draw the new margin’s boundary against, and the change either applies everywhere or refuses to save the way you expect.

When a margin change doesn’t stick#

Symptom	Likely cause	Fix
Only part of the document changed	Apply to was set to “This point forward” instead of “Whole document”	Reopen Custom Margins and switch Apply to
“This section” option is missing	No section break exists in the file	Insert one via Layout > Breaks, then reopen margins
Printed page still cuts off text	Margin is narrower than the printer’s minimum printable area	Check the printer’s properties for its minimum margin, then widen yours
New documents still open with the old margin	Set As Default only changes the template for documents created after that point	Reopen this file and reset its margins manually too

Margins are one of the settings that quietly breaks when a document gets copied, converted, or emailed between different Word versions, so it’s worth a quick check after any of those. That goes double for a file that started life as a PDF converted to Word, since conversion tools often reconstruct margins imperfectly — and worth a second look if the document also has tracked changes turned on, since a reviewer’s edits and a margin adjustment can both shift where text lands on the printed page.

Common questions#

Why is the Margins button grayed out?#

The document is protected or opened read-only. Go to Review > Restrict Editing and select Stop Protection, or clear “Always Open Read-Only” under File > Info > Protect Document, then reopen the file.

Why did my margin change apply to only part of the document?#

The Apply to box in Custom Margins was set to “This point forward” instead of “Whole document.” Reopen Layout > Margins > Custom Margins and switch Apply to before clicking OK.

How do I change Word’s margins from inches to centimeters?#

Word follows your regional setting, but you can force the unit: go to File > Options > Advanced, find “Show measurements in units of” under Display, and pick Centimeters. The Custom Margins boxes then accept centimeter values.

Why do I get “One or more margins are set outside the printable area”?#

The margin is smaller than your printer’s unprintable border. Choose Fix to let Word bump it to the minimum, or widen the margin yourself, then check the printer’s properties for its true minimum.
