Before You Start

Microsoft Outlook Desktop App: This guide is written for the full desktop version of Outlook included with Microsoft 365, Outlook 2021, or Outlook 2019 on Windows. The steps are very similar for macOS, but menu locations may differ slightly.
Identify Your Goal: Know which part of Outlook you want to change. Changing the font for reading emails is a different setting from changing the font you write with.

Check first: The most common point of confusion is the difference between changing the font for reading versus composing. Adjusting one will not affect the other. This guide covers both, so make sure you follow the correct steps for your needs.

Step-by-Step Instructions

1. Temporarily Increase Font Size While Reading an Email

This is the quickest way to make a single email easier to read without changing any permanent settings. It's perfect for when you receive a message with unusually small text.

Open the email in the Reading Pane or in its own window. Look to the bottom-right corner of the Outlook window. You will see a Zoom slider with a percentage next to it (e.g., 100%). Click and drag the slider to the right to increase the font size, or click the '+' button. The text in the email body will get larger immediately. This change is temporary and only affects the email you are currently viewing. It will reset for the next email you select.

Tip: You can also use a keyboard shortcut. Click anywhere inside the email's body, then hold the Ctrl key on your keyboard and scroll up with your mouse wheel to zoom in.

2. Permanently Change the Default Font Size for Reading Emails

If you find yourself zooming in on every email, it's better to change the default setting. This method does not work for all email formats (HTML emails with hard-coded fonts may override it), but it works for most plain text messages and helps set a baseline.

First, navigate to the View tab on the Outlook ribbon at the top of the screen. Click on View Settings, which will open a new "Advanced View Settings" window. In this window, click the Other Settings button. You'll see options for "Column Font" and "Row Font." For the Reading Pane, the key is to ensure the "Use compact layout..." setting is configured correctly, though the primary control is the zoom feature. For plain text emails, the setting is located elsewhere. Go to File > Options > Mail > Stationery and Fonts. Click the Font button under "Composing and reading plain text messages" to set a comfortable size, like 12pt.

3. Change the Default Font Size for Composing New Emails

This is how you control the font that your recipients will see. If people have told you that your emails are hard to read, this is the setting you need to change. It controls the font for new messages, replies, and forwards.

Click on the File tab in the top-left corner, then select Options from the left-hand menu. In the "Outlook Options" window, click on the Mail category. Now, click the Stationery and Fonts button. A new "Signatures and Stationery" window will appear. Here you will see separate sections:

New mail messages: This sets the font for brand new emails you compose.
Replying or forwarding messages: This sets the font when you reply or forward. You can set it to be different from new messages if you wish.

Click the Font button for each section you want to change. Select your desired font (e.g., Calibri, Arial), font style (e.g., Regular), and size (12pt is a good standard). Click OK on each window to save your changes.

4. Increase the Font Size of the Email List (Inbox View)

Making the text in your list of emails larger can dramatically improve how quickly you can scan your inbox. This changes the font for the sender, subject, and date columns.

Go to the View tab on the ribbon. Click on View Settings. In the "Advanced View Settings" window that pops up, click on Other Settings. In this new dialog box, you can adjust the font sizes for different parts of the list. Click the Font button next to "Row Font" to change the size of the text for each individual email in the list. A size of 10pt or 11pt is often more readable than the default. You can also change the "Column Font" if the headers ("From", "Subject", etc.) are too small. Click OK to apply the changes.

Tip: If your changes don't seem to apply, you might be using the "Compact" message list layout. Try switching to the "Single" layout under the View > Change View menu, and then re-apply your font settings.

5. Enlarge the Font in the Folder Pane

The Folder Pane is the column on the far left that lists your Inbox, Sent Items, Drafts, and other folders. You can't change this font size directly within Outlook's font settings, as it's controlled by your computer's operating system.

To make this text bigger, you need to change your system's display scaling. On Windows 11, right-click your desktop and choose Display settings. Under "Scale & layout," you'll find a "Scale" dropdown menu. The default is usually 100%. Try increasing it to 125%. This will make text and icons larger across all of your applications, including the Outlook Folder Pane. You may need to sign out and sign back in for the changes to take full effect.

This is a system-wide change, so be prepared for everything on your screen to get bigger. If this is too drastic, you may have to stick with the default size in the Folder Pane.

6. Adjust the Font Size in Your Outlook Calendar

Just like your inbox, your calendar can become hard to read. You can increase the font size for appointments and meetings to make your schedule clearer.

Navigate to your Calendar in Outlook. Go to the View tab on the ribbon, and just as you did for the mail view, click View Settings. Click on Other Settings. In the dialog that opens, you can change the font for the "Time" and the main "Font" used for appointments. Click the respective Font buttons, choose a larger size, and click OK. This will make the text within your calendar grid larger and easier to see at a glance.

Common Problems When You Make Outlook Font Bigger

Problem: My font changes don't seem to save or apply correctly.

Sometimes, an Outlook view can become corrupted, preventing changes from being saved. The simplest fix is to reset the view to its default state. Go to the View tab and click the Reset View button. After resetting, try applying your desired font size changes again. Note that this will also reset any other customisations you've made to that view, such as column arrangements.

Problem: I made the font bigger, but people say my emails are still tiny.

This is a classic mix-up between the reading font and the composing font. You likely used the Zoom slider or changed the view settings, which only affects how you see emails. To control what your recipients see, you must change the composing font. Go to File > Options > Mail > Stationery and Fonts and set the font for "New mail messages" and "Replying or forwarding messages."

Problem: The font is larger for some incoming emails, but not others.

This happens because many companies send marketing or transactional emails using HTML, which can have the font size "hard-coded" into the message. These specific font styles will often override your personal Outlook reading settings. There isn't a simple way to force your font on all HTML emails, but your settings will still apply to plain text emails and many standard HTML messages.

Problem: The menus, ribbon, and buttons are still too small.

The main user interface elements of Outlook (like the File, Home, and View tabs) are not controlled by the font settings within the application. Their size is determined by your overall Windows (or macOS) display scaling settings. To make them bigger, you must increase the scaling for your entire operating system, as described in Step 5.

Advanced Tips for Making Outlook Font Bigger

Use Conditional Formatting for Important Emails: Want emails from your manager to stand out? You can use Conditional Formatting to automatically make them appear with a larger font in your email list. Go to View > View Settings > Conditional Formatting. Click Add, give your rule a name (e.g., "Manager"), click the Font button to set a larger size, and then click Condition to specify the criteria (e.g., "from: manager@example.com").
Create and Save Custom Views: If you sometimes need a very large font but don't want it all the time, create a special view. Set up the font sizes exactly as you like them in your message list and reading pane, then go to View > Change View > Save Current View As a New View. Give it a name like "Large Print." Now you can easily switch between your standard view and your large print view from the "Change View" menu.
Understand Plain Text vs. HTML: Be aware that Outlook has a separate font setting for plain text emails. You can find it in File > Options > Mail > Stationery and Fonts under the "Composing and reading plain text messages" section. If some emails still appear in a small, basic font like Courier New, adjusting this setting will likely fix it.

How To Make Outlook Font Bigger FAQ

How do I make the font bigger in the Outlook mobile app?

The Outlook app for iOS and Android doesn't have its own internal font size settings. Instead, it respects the system-wide font size you've set on your device. To change it, go into your phone's main Settings app, then look for Display or Accessibility, where you'll find a "Font Size" or "Text Size" slider.

What about the web version of Outlook (Outlook.com)?

For Outlook on the web, you have two main options. The easiest is to use your browser's built-in zoom function (press Ctrl and + on Windows, or Cmd and + on Mac). To change the default font for composing emails, click the gear icon (Settings) in the top right, then View all Outlook settings > Mail > Compose and reply. You can set your default message font size there.

Will changing my font in Outlook affect Word or Excel?

No. All the font settings described in this guide are contained entirely within the Outlook application. They will have no effect on other Microsoft Office programs like Word, Excel, or PowerPoint.
