Change your default font before you start typing

The fastest way to change Word's default font is to open a blank document, select all text with Ctrl+A (or Cmd+A on Mac), then pick a new font from the Home tab. After you change it, click the small arrow in the bottom right corner of the Font group and select Set as Default. Word will ask you to confirm — choose All documents based on the Normal template and click OK. Every new document you create will use that font from then on.

This method works the same way in Word 2019, Word 2021, and Microsoft 365. The location of the Set as Default button is identical across all three versions. If you cannot find the arrow, look for a tiny diagonal line with an arrow pointing to it in the Font group on the Home tab — that opens the font dialog where the option lives.

Changing the default does not affect documents you have already created. Those keep whatever font they were using when you made them. Only new blank documents will open with your chosen font.

Key Takeaways

  • Open a blank document, select all text with Ctrl+A, pick your font, then click the arrow in the Font group and choose Set as Default.
  • Choose "All documents based on the Normal template" when Word asks you to confirm the change.
  • The default font change only affects new documents you create after making the change, not existing files.
  • If you use multiple computers or share documents with others, they will see your chosen font only if it is installed on their machine.
  • You can change the default font size, color, and line spacing the same way — select them all before you set as default.

Why Word defaults to Calibri (or Aptos in newer versions)

Microsoft Word comes set to Calibri as the default font in older versions and Aptos in Word 2024 and newer Microsoft 365 subscriptions. These are sans-serif fonts — they have no small lines at the ends of letters — and they were chosen because they read clearly on screens and in printed documents. Calibri has been the standard since Word 2007.

Aptos is Microsoft's newer choice, designed specifically for digital reading and printing. If you have a recent Microsoft 365 subscription and your default font switched to Aptos without you changing it, that is why. You can switch back to Calibri or any other font using the method above.

Change font size and spacing at the same time

When you set a new default font, you can also change the default size and line spacing in one step. After you select all text in a blank document, adjust the font size (usually in the same Font group), line spacing (on the Home tab under Paragraph), and any other formatting you want. Then click the Font dialog arrow and select Set as Default.

For example, if you want all your documents to use 12-point Garamond with 1.5 line spacing, select all, change to Garamond, change the size to 12, set line spacing to 1.5, then set as default. Word will remember all three settings for every new document.

Be careful not to change formatting in an existing document and then set it as default — Word will only explore the default to new documents, not the one you are currently editing. Always start with a blank document when you want to change the default.

What happens if the font is not installed on another computer

If you send a document to someone else and they do not have your chosen font installed on their computer, Word will substitute it with a similar font automatically. The document will still open and be readable, but it may not look exactly the way you formatted it. The text might wrap differently, spacing might shift, and the overall appearance could change.

Common fonts like Arial, Times New Roman, Calibri, and Garamond are installed on almost every Windows and Mac computer, so documents using those fonts usually look the same everywhere. Newer or specialty fonts are less likely to be on someone else's machine. If you are sharing documents with others, stick to widely available fonts to avoid surprises.

Revert to Word's original default font

If you want to go back to Word's factory default, open a blank document and change the font back to Calibri (or Aptos if you have Word 2024 or newer). Select all, then set it as default the same way. You can also delete the Normal template file, which will force Word to recreate it with the original settings, but changing the font directly is simpler.

The Normal template is the file Word uses to create every new blank document. It stores your default font, spacing, margins, and other formatting choices. Deleting it is safe — Word will rebuild it automatically the next time you open the program — but it will also erase any other customizations you have made to new documents.

Different default fonts for different document types

Word only has one default font for all new blank documents. You cannot set one font for letters and another for reports using the standard interface. However, you can create custom templates with different default fonts and use those instead of the blank document.

To do this, create a document with your chosen font and formatting, then save it as a template by going to File, then Save As, and choosing Word Template (.dotx) from the file type dropdown. Give it a name like "Letter Template" or "Report Template". The next time you want to start a new document, go to File, then New, and your custom template will appear as an option to use instead of the blank document.

Frequently Asked Questions

Will changing my default font affect documents I already have open?

No. The default font change only applies to new documents you create after making the change. Any document you have already started or finished keeps the font it had when you created it. Close and reopen an existing document and it will still use its original font.

Can I set a different default font for Word and Excel?

Yes. Each Microsoft Office program has its own default font setting. Changing the default in Word does not change Excel's default. Open Excel, select a blank cell, change the font, then look for the equivalent Set as Default option in Excel's Format menu. The steps are slightly different for each program.

What if I cannot find the Set as Default button?

Look for a small arrow or diagonal line with an arrow in the Font group on the Home tab. Click it to open the Font dialog box. The Set as Default button is at the bottom of that dialog. If you still cannot find it, you may be using an older version of Word — try right-clicking the font name in the font list instead.

Does my default font choice sync across my devices if I use Microsoft 365?

No. Each device stores its own default font setting. If you change the default on your laptop, your desktop computer will not automatically update. You will need to change the default separately on each machine you use Word on.

Can I change the default font just for this document?

Yes, but it is simpler to just change the font in that document without setting it as default. Select all the text, pick your font, and leave it at that. Only use Set as Default if you want every new document to use that font going forward.
