How to Change the Default Font in Microsoft Word

If every new document you open starts with Calibri 11pt and you'd rather be working in something else, you're not stuck with it. Word lets you change the default font permanently — but the method, and what "permanent" actually means, depends on a few things about how you work.

What "Default Font" Actually Means in Word

When Word opens a blank document, it pulls formatting from a template file called Normal.dotm. This template controls the baseline appearance of new documents — including the default font, size, line spacing, and paragraph style. Changing the default font means updating that template so every new blank document inherits your preferred settings automatically.

This is different from:

  • Changing the font in a single document (which only affects that file)
  • Changing a font in a specific style like Heading 1 (which only affects that style)
  • Changing fonts in a template other than Normal.dotm (which only affects documents built on that template)

Understanding this distinction matters, because if you apply a font change the wrong way, it looks like it worked — until you open a new document and it reverts.

How to Change the Default Font in Word 🖊️

On Windows (Microsoft 365 / Word 2016 and later)

  1. Open a blank Word document
  2. Go to the Home tab and click the small arrow in the bottom-right corner of the Font group to open the Font dialog box
  3. Choose your preferred font, style (Regular, Bold, etc.), and size
  4. Click Set As Default at the bottom-left of the dialog
  5. When prompted, select All documents based on the Normal template and click OK

That last step is critical. If you choose "This document only," nothing changes globally.

On Mac (Microsoft 365 / Word for Mac)

The steps are nearly identical:

  1. Open a blank document
  2. Go to FormatFont from the menu bar
  3. Set your preferred font, style, and size
  4. Click Default → confirm you want to apply it to all documents based on the Normal template

Using the Style Method (More Control)

For users who want deeper control — particularly if you use styles throughout your documents — the better approach is modifying the Normal paragraph style directly:

  1. Right-click Normal in the Styles pane
  2. Select Modify
  3. Change the font settings in the dialog
  4. Check New documents based on this template
  5. Click OK

This method updates the font wherever the Normal style is applied, which tends to be more consistent across complex documents.

Why the Change Sometimes Doesn't Stick

This is one of the most common frustrations, and it has a few known causes:

CauseWhat HappensFix
Selected "This document only"Change applies to current file onlyRedo and select Normal template option
Normal.dotm is read-onlyWord can't save changes to the templateCheck file permissions on the template
IT/admin policyOrganization-managed installs may reset defaultsContact your IT department
OneDrive sync conflictCloud sync overwrites local template changesPause sync before making changes
Word installed on multiple devicesChanges made on one device don't apply elsewhereRepeat on each device

The Normal.dotm file lives in a specific folder on your machine. On Windows, it's typically found at C:Users[YourName]AppDataRoamingMicrosoftTemplates. On Mac, it's in ~/Library/Group Containers/UBF8T346G9.Office/User Content/Templates. If something keeps resetting, that's the file to examine.

What Changes and What Doesn't 🔍

Changing the default font affects new blank documents going forward. It does not:

  • Retroactively change fonts in existing documents
  • Override fonts set by a different template (e.g., a company letterhead template)
  • Affect documents received from other people
  • Change fonts in documents that use styles explicitly set to a different font

If you open a document someone else created and it shows a different font, that's expected — their document has its own embedded formatting.

The Variables That Affect Your Outcome

Several factors shape how this plays out in practice:

Version of Word — The menus and dialog labels differ slightly between Word 2013, 2016, 2019, and Microsoft 365. The core method is the same, but screenshots or tutorials from older versions may show different button placements.

How you use Word — If you mostly work from blank documents, updating Normal.dotm solves the problem cleanly. If you work from custom templates (legal forms, branded documents, academic formats), those templates have their own font settings that override Normal.dotm entirely.

Managed vs. personal install — On a personal computer, you have full control. On a work or school machine managed by an IT department, your ability to permanently modify templates may be restricted or regularly reset by policy.

Single device vs. multiple devices — There's no built-in sync for Normal.dotm across devices through Microsoft 365. If you work across a desktop and a laptop, you'd need to update the default font on each machine separately, or manually copy the template file between them.

Shared documents workflow — If your work involves frequent collaboration or documents that travel between users, default font settings matter less than you'd expect. Received documents carry their own formatting, and shared templates often govern the look regardless of what your personal defaults are set to.

The right approach depends significantly on what you're actually trying to solve — whether it's a personal preference for solo work, a consistency need across a team, or something in between.
