How to Make Outlook Email Text Bigger

If you squint at your Outlook inbox or struggle to read message text, you can enlarge the font in a few clicks. This guide shows you how to increase text size for the folder pane, message list, reading pane, and the emails you compose. You’ll need access to Outlook’s settings—no special permissions required.

What You’ll Need

• Outlook desktop app (Windows or Mac) or Outlook on the web (browser).
• For the desktop app, a Microsoft account or work/school account that’s already signed in.
• For the web version, a supported browser (Edge, Chrome, Firefox, Safari).

Step-by-Step

Outlook Desktop (Windows)

1. Open Outlook on your Windows PC.
2. Click the File tab in the top-left corner.
3. In the left sidebar, select Options.
4. In the Outlook Options window, click Mail in the left pane.
5. Under the Compose messages section, click the Stationery and Fonts button.
6. In the dialog that appears, you’ll see three font buttons: New mail messages, Replies and forwards, and Composing and reading plain text messages. Click each one and choose a larger font size (e.g., 14 or 16 pt) from the Size dropdown. Click OK after each.
7. To change the reading pane font, go back to Outlook Options and select Mail → Reading pane (or in some versions, Display). Look for a Font button and increase the size there.
8. For the folder pane and message list, click View tab, then View Settings (or Change View → Manage Views). Click Other Settings, then under Column Font and Row Font, choose a larger size.
9. Click OK on all open dialog boxes to save changes.

Outlook on the Web (Browser)

1. Go to outlook.com or your work/school Outlook web app and sign in.
2. Click the gear icon (Settings) in the top-right corner.
3. Scroll to the bottom of the Settings pane and click View all Outlook settings.
4. In the settings window, select General → Accessibility.
5. Under Text size, drag the slider to the right to increase the font size. You’ll see a preview. Click Save at the bottom.
6. To change the font for emails you write, go to Mail → Compose and reply. Under Message format, you can set a default font size for new messages and replies. Choose a larger size (e.g., 14 or 18).

Outlook Desktop (Mac)

1. Open Outlook on your Mac.
2. In the top menu bar, click Outlook → Preferences.
3. Click Fonts.
4. You’ll see buttons for Message list, Reading pane, Compose, and Notes. Click each and choose a larger font size.
5. Close the preferences window—changes save automatically.

Common Mistakes

• Only changing the compose font: Many users change the font for new emails but forget that the reading pane and folder list have separate settings. You need to adjust each one individually.
• Using the Zoom tool instead of font settings: In Outlook on the web, pressing Ctrl+Plus zooms the entire browser page, which can break the layout. Use the accessibility slider for clean text scaling.
• Changing the wrong default: In desktop Outlook, the “Stationery and Fonts” dialog has three separate buttons—if you only change “New mail messages,” replies and forwards will still use the old size.
• Not saving changes: In the web version, you must click Save after adjusting the slider. If you close the settings window without saving, your changes are lost.

Tips

• If you only need to read one email quickly, hold Ctrl (Windows) or Cmd (Mac) and scroll up with your mouse wheel to zoom in—this works in the reading pane.
• Set your default font size to 14 pt or higher for comfortable reading; 12 pt is often too small for long emails.
• In Outlook on the web, you can also use your browser’s built-in zoom (Ctrl+Plus or Cmd+Plus) to enlarge everything, but be aware it may cause horizontal scrolling.
• If you use Outlook on multiple devices, you’ll need to set the text size on each device—settings don’t sync across platforms.

Troubleshooting

• Font size didn’t change in the reading pane: In desktop Outlook, the reading pane font is controlled by the “Reading pane” settings, not the compose fonts. Go to File → Options → Mail → Reading pane and set the font there.
• Changes only apply to new emails, not existing ones: That’s normal—the compose font only affects messages you create after the change. To read old emails with a larger font, adjust the reading pane font.
• Web version slider doesn’t affect the message list: The accessibility slider in Outlook on the web only changes the reading pane and compose area. To enlarge the folder list, use your browser’s zoom (Ctrl+Plus) or increase the browser’s default font size in its settings.
• Font size reverts after restart: Make sure you clicked OK or Save in every dialog. In desktop Outlook, if you close the Options window without clicking OK, changes are discarded.
• Can’t find the “Stationery and Fonts” button: In newer Outlook versions, it may be under File → Options → Mail → Compose messages. If you still don’t see it, try the View tab → View Settings → Other Settings → Font for the reading pane.

Frequently Asked Questions

Does changing the font size in Outlook affect emails I send?

Yes, changing the default compose font will apply to new messages you create. However, recipients may see a different font if their email client overrides it—but the size you choose will be reflected in most clients.

Can I make the text bigger only for a specific email?

Yes. In the reading pane, hold Ctrl (Windows) or Cmd (Mac) and scroll up with your mouse to zoom in on that email. This is temporary and resets when you select another message.

Why doesn’t the accessibility slider in Outlook on the web change the folder list?

The slider is designed for the reading pane and compose area only. To enlarge the entire interface, use your browser’s zoom feature (Ctrl+Plus or Cmd+Plus).

Will these settings sync across my devices?

No. Outlook desktop and web have separate settings. You’ll need to adjust the text size on each device you use.

What is the best font size for readability?

Most people find 14 pt comfortable for reading on screen. If you have vision issues, try 16 pt or higher. The accessibility slider in the web version goes up to 24 pt.

Can I set a larger font for replies only?

Yes. In desktop Outlook, the “Replies and forwards” button in the Stationery and Fonts dialog lets you set a different size for replies. In the web version, you can set a separate font for “Replies and forwards” under Mail → Compose and reply.
