Outlook Change Customize Navigation Pane Font Size

Yes, you can change the font size of the navigation pane in Outlook, but there is no dedicated setting for it. The navigation pane (which shows Mail, Calendar, People, and Tasks) uses the Windows system font size, so you adjust it through Windows display settings, not within Outlook itself. Below we explain the exact steps for Windows 10 and 11, what to expect, and a few workarounds if you want more control.

How Outlook’s Navigation Pane Font Size Works

Outlook is a desktop application that follows the Windows system font scaling. The navigation pane—the column on the left with icons and folder names—uses the same font as other Windows apps. When you increase the Windows display scaling (e.g., from 100% to 125%), Outlook’s navigation pane text becomes larger. This is not a per-app setting; it affects all text in Outlook, including the message list, reading pane, and ribbon.

If you only want to enlarge the navigation pane without changing other Outlook text, there is no built-in option. You can, however, use Windows’ per-app DPI override (explained later) to scale Outlook independently, but that will scale the entire Outlook window, not just the navigation pane.

How to Change the Font Size via Windows Settings

Here are the steps for Windows 10 and Windows 11:

  1. Right-click on the desktop and select Display settings (or go to Settings > System > Display).
  2. Under Scale and layout, find the dropdown labeled Change the size of text, apps, and other items (Windows 10) or Scale (Windows 11).
  3. Choose a percentage higher than your current setting—e.g., 125% or 150%. The default is often 100% or 125% depending on your screen resolution and size.
  4. Windows will ask you to sign out or restart for the change to apply to all apps. Sign out and back in, or restart your PC.
  5. Open Outlook. The navigation pane text should now be larger.

Note: Increasing scaling will make everything on your screen larger, not just Outlook. If you only want Outlook to be larger, use the per-app DPI override method below.

Per-App DPI Override for Outlook

If you want to enlarge Outlook without changing the rest of your system, you can force Windows to scale Outlook separately. This is useful if you find the global scaling makes other apps too large.

  1. Close Outlook completely.
  2. Right-click the Outlook shortcut (on the desktop or in the Start menu) and select Properties.
  3. Go to the Compatibility tab.
  4. Click Change high DPI settings.
  5. Check the box Override high DPI scaling behavior.
  6. In the dropdown, select System (Enhanced) or System. System (Enhanced) is usually better for modern apps.
  7. Click OK and then Apply.
  8. Restart Outlook. It should now use the system scaling factor you set in Windows, even if you later change the global scaling back.

This method scales the entire Outlook window, not just the navigation pane. There is no way to isolate the navigation pane specifically.

Using Windows Magnifier as a Temporary Workaround

If you only need a quick zoom-in on the navigation pane without changing any settings, you can use the built-in Magnifier tool:

  • Press Windows key + Plus (+) to open Magnifier.
  • Use Windows key + Plus to zoom in, and Windows key + Minus (-) to zoom out.
  • You can set Magnifier to follow the mouse cursor, so it enlarges the area you point at.

This is not a permanent solution, but it helps if you need a quick look at a small text.

Common Problems and Misconceptions

“I changed the Windows scaling, but Outlook didn’t change.â€� This can happen if you didn’t sign out and back in after changing the scaling. Also, if you have the per-app DPI override set to Application, Outlook will ignore the system scaling. Check the Compatibility tab.

“I want to change only the navigation pane font, not the whole app.� Outlook does not have a built-in option to customize the navigation pane font size independently. You can only change the overall font size via Windows scaling.

“The text is too large now.� Simply revert the Windows scaling to a lower percentage, or disable the per-app override.

Alternatives: Changing Font Size in Other Parts of Outlook

While the navigation pane uses the system font, you can change the font size of the message list and reading pane within Outlook’s settings:

  • Go to File > Options > Mail.
  • Under Compose messages, you can set the default font for new messages.
  • For the reading pane, go to View > View Settings > Other Settings and adjust the column font size.

These changes do not affect the navigation pane.

Frequently Asked Questions

Q: Can I change the navigation pane font size in Outlook’s options?
A: No, Outlook does not have a built-in setting for the navigation pane font size. It follows the Windows system font scaling.

Q: Will changing Windows display scaling affect all my other apps?
A: Yes, it will increase the size of text and icons in all applications that support scaling. Some older apps may appear blurry; you can fix that with the per-app DPI override.

Q: Why is my Outlook navigation pane text so small?
A: This usually happens when your Windows display scaling is set to a lower percentage, or your screen resolution is very high (e.g., 4K) without scaling. Increase the scaling in Windows settings.

Q: Is there a way to make only the navigation pane larger without affecting the rest of Outlook?
A: No, not directly. You can use the per-app DPI override to scale the entire Outlook window, but that will also enlarge the message list and ribbon.

Q: Does Outlook for Mac have a different way to change the font size?
A: On a Mac, you can use the macOS system font size settings (System Preferences > Displays > Larger Text) to scale Outlook. Outlook for Mac also has a zoom feature for the reading pane (View > Zoom).
