Restart Outlook Watch out for

Before You Start

You will need a working installation of the Microsoft Outlook desktop application (e.g., Outlook for Microsoft 365, Outlook 2019, 2021). This guide focuses on the desktop version, as settings for Outlook on the web (Outlook.com) or mobile apps are different.
Basic familiarity with your computer's operating system (Windows) is helpful, especially for adjusting display settings that can affect Outlook's interface fonts.
Ensure Outlook is closed before making system-wide display changes, and restart it afterwards for changes to take full effect.

Check first: Understand that there isn't one single setting to change *all* font sizes in Outlook. You'll need to adjust different settings for composing emails, reading emails, and the Outlook interface itself. Changing display scaling in Windows will affect all applications, not just Outlook.

Step-by-Step Instructions

Adjust Font Size for Composing New Emails

This setting changes the default font, size, and colour used when you create a brand new email message. This helps ensure your outgoing messages are clear and easy for recipients to read.

Open Microsoft Outlook.
Click on the File tab in the top-left corner of the Outlook window. This will take you to the Backstage view.
In the left-hand navigation pane, click on Options. This will open the Outlook Options dialogue box.
In the Outlook Options window, select Mail from the left-hand menu.
Under the "Compose messages" section, locate and click the Stationery and Fonts... button. This opens another dialogue box titled "Signatures and Stationery".
Under the "Personal Stationery" tab, find the "New mail messages" section. Click the Font... button next to it.
A standard Font dialogue box will appear. Here, you can choose your desired Font, Font style (e.g., Regular, Italic, Bold), and most importantly, the Size. Select a larger size that suits your needs, such as 12 or 14 points, depending on your preference.
Click OK to confirm your font selection in the Font dialogue box.
Click OK in the Signatures and Stationery dialogue box.
Click OK in the Outlook Options dialogue box to apply all changes.

Tip: You can see a preview of your selected font, style, and size in the Font dialogue box before you confirm, helping you decide if it's readable enough.

Adjust Font Size for Replying and Forwarding Emails

Similar to new messages, you can set a default font for when you reply to or forward emails. This ensures consistency in your communications and prevents the default font from reverting to something smaller after the initial message.

Follow steps 1-5 from the previous section to navigate to the Signatures and Stationery dialogue box (File > Options > Mail > Stationery and Fonts...).
Under the "Personal Stationery" tab, find the "Replying or forwarding messages" section. Click the Font... button next to it.
In the Font dialogue box that appears, select your preferred Font, Font style, and Size. Again, choosing a larger size will enhance readability for your replies and forwards.
Click OK to confirm your selection in the Font dialogue box.
Click OK in the Signatures and Stationery dialogue box.
Click OK in the Outlook Options dialogue box to save these changes.

Tip: If you use different fonts or sizes for new messages versus replies, remember that the recipient's email client ultimately determines how the font displays on their screen, but your chosen size provides a good starting point.

Temporarily Zoom the Reading Pane

When you're reading an email in the Reading Pane (the preview area for messages), you can quickly and temporarily increase the text size without changing any default settings. This is useful for particularly long emails or when your eyes need a momentary break.

Open Outlook and click on an email in your Inbox or any other folder to display it in the Reading Pane.
Look for the Zoom slider at the bottom-right corner of the Outlook window. It usually shows a percentage (e.g., 100%).
Click and drag the slider to the right to increase the zoom percentage. The text in the Reading Pane will immediately become larger.
Alternatively, you can hold down the Ctrl key on your keyboard and scroll your mouse wheel upwards. Scrolling downwards will decrease the zoom.
A third method is to go to the View tab on the Outlook ribbon, and in the "Zoom" group, click Zoom. You can then select a preset percentage or type in a custom one.

Tip: The Reading Pane zoom often resets when you switch emails or restart Outlook. If you want a more permanent change for reading, you might need to adjust your system's display settings, as detailed in a later step.

Change Font Size for the Message List (Inbox Items)

The message list shows details like sender, subject, and date for each email in your inbox. Making these larger can greatly improve navigation and quick scanning of your emails. Outlook's direct controls for this are somewhat limited, but there are effective methods.

Open Outlook and navigate to your Inbox or any other mail folder.
Go to the View tab on the Outlook ribbon.
In the "Current View" group, click on View Settings. This will open the Advanced View Settings dialogue box.
Click the Other Settings... button.
Under the "Grid Lines and Font" section, find the "Row Font" area. Click the Font... button.
In the Font dialogue box, select your desired Font, Font style, and Size for the message list rows. Choose a larger size to make the sender and subject lines more visible.
Click OK to confirm your font choice for the rows.
You can also adjust the font for "Column Font" if you wish to change the headers of the columns (e.g., From, Subject, Received).
Click OK in the Other Settings dialogue box.
Click OK in the Advanced View Settings dialogue box.
You may need to restart Outlook for these changes to fully take effect across all views.

Tip: This change applies only to the current view you are in (e.g., 'Compact' view). If you switch to a different view or create a new custom view, you might need to apply these settings again.

Increase Font Size for the Folder Pane and Outlook Interface

The Folder Pane (left-hand side, showing your mail folders) and other elements of the Outlook interface (like the ribbon, status bar) are often controlled by your computer's overall display settings, rather than directly by Outlook. Adjusting these can make the entire application easier to use.

Close Outlook completely before proceeding with these steps, as system display changes often require applications to restart to apply correctly.
For Windows 10/11: Right-click on an empty area of your desktop and select Display settings.
Under the "Scale and layout" section, find the "Change the size of text, apps, and other items" or "Scale" dropdown menu.
Select a higher percentage (e.g., 125%, 150%). This will scale all elements on your screen, including the Outlook interface, making fonts and icons larger.
Once you've selected a new scale, close the Display settings window.
Re-open Outlook. You should now see that the Folder Pane, the ribbon, and other interface elements have increased in size.
For older Windows versions: The process might involve going to Control Panel > Appearance and Personalization > Display and adjusting the "Make text and other items larger or smaller" setting.

Tip: Increasing the system-wide display scaling affects *all* applications on your computer, not just Outlook. Test different percentages to find a comfortable balance that works across all your software.

Adjust Font Size for Calendar, Tasks, and Contacts Views

Outlook's Calendar, Tasks, and Contacts sections often have their own specific view settings for font sizes. These might not always be directly tied to the main mail view settings.

Open Outlook and switch to the Calendar, Tasks, or Contacts view using the navigation bar at the bottom or left side of the Outlook window.
Once in the desired view (e.g., Calendar), go to the View tab on the Outlook ribbon.
Click on View Settings in the "Current View" group.
Depending on the specific view (e.g., Day/Week/Month for Calendar, List for Tasks), you may see an Other Settings... button or a direct Conditional Formatting... option.
If an Other Settings... button is available, click it. Look for options related to "Font" or "Row Font" and adjust them as you did for the Message List.
If there's a Conditional Formatting... option, you can use it to apply different font styles and sizes based on specific conditions, which can sometimes indirectly make certain items stand out more. However, this is more complex than a general font size change.
For calendar views, specifically, some elements like the time scale on the left or event details within the grid might also be affected by the Windows Display Settings mentioned in the previous step.
Adjust the font size as needed in the respective dialogue boxes and click OK through all open windows to apply the changes.

Tip: Customising calendar views can be very specific. For instance, in the Calendar, you might find options like 'Font for appointments' under 'Other Settings' depending on your Outlook version. Explore all available 'Font' buttons within the 'View Settings' for each specific Outlook module.

Common Problems When You Increase The Font Size In Outlook

Important: Always restart Outlook after making significant font or display changes, especially those related to system settings, to ensure they apply correctly.

Changes Aren't Taking Effect

Problem: You've adjusted a font setting, but the text size in Outlook hasn't changed, or only partially changed.

Solution: Outlook often needs a full restart for font changes to be applied across the entire application. Close Outlook completely (ensure it's not just minimised or running in the background processes) and then reopen it. If you changed Windows Display Settings, a system restart might even be necessary for some older Windows versions or specific display drivers, though typically closing and reopening apps is enough.

Only Some Fonts Changed

Problem: You increased the font size, but only new emails are larger, or only the reading pane, while other parts of Outlook remain small.

Solution: As this guide explains, Outlook has multiple, independent font settings. You might have only adjusted the font for composing new messages, or only for the message list. Review the step-by-step guide and ensure you've adjusted the specific font setting for the area you want to change (e.g., Folder Pane, Reading Pane, Calendar view). Remember that the Folder Pane and main interface elements are typically controlled by Windows Display Settings.

Text Looks Blurry or Pixelated

Problem: After increasing the font size, particularly via Windows Display Settings, some text or images in Outlook (or other apps) appear blurry or less sharp.

Solution: This can happen with display scaling, especially on certain monitors or graphics cards. Try adjusting the display scaling percentage in smaller increments (e.g., from 100% to 125%, then to 150%) to see if a particular setting causes blurriness. Ensure your display drivers are up to date. Sometimes, simply choosing a different font (even at the same size) can make a difference if the current font doesn't scale well. In Windows, you can also explore advanced scaling settings if available, though these are less common now.

Recipients Don't See My Chosen Font Size

Problem: You set a large font size for your outgoing emails, but recipients still say the text is small, or it looks different on their end.

Solution: The font and size you choose for composing emails are suggestions. The recipient's email client (e.g., Gmail, Apple Mail, another Outlook) determines how the message is ultimately displayed on their screen. Their own default settings, zoom levels, and even the type of device they are using (desktop, tablet, phone) can affect the appearance. While your chosen font size increases the chance of readability, you cannot force a recipient's client to display it exactly as you see it. Focus on choosing a universally readable font like Arial, Calibri, or Times New Roman, and a size that is generally considered good for reading (e.g., 11-14pt).

Outlook.com (Web) Font Size Is Still Small

Problem: You've made changes in the desktop Outlook app, but the font size in Outlook.com (accessed via a web browser) is unchanged.

Solution: The desktop Outlook application and Outlook.com (the web-based version) are separate platforms. Settings made in one do not transfer to the other. To increase font size in Outlook.com, you need to use your web browser's zoom function (usually Ctrl + + to zoom in, Ctrl + - to zoom out, or check your browser's menu for zoom options) or its specific display settings. Outlook.com itself also has limited accessibility settings in its own settings menu.

Advanced Tips for How Do I Increase The Font Size In Outlook

Utilise Windows Accessibility Settings

Beyond simple display scaling, Windows offers dedicated accessibility features that can help. Go to Settings > Accessibility > Text size (Windows 11) or Ease of Access > Display (Windows 10). Here, you can adjust "Text size" which specifically scales text elements across Windows and compatible applications like Outlook, often with better clarity than general display scaling.

Customise Your Reading Pane Further with Conditional Formatting

For advanced users, Outlook's "Conditional Formatting" can make specific emails stand out with larger fonts. Go to the View tab > View Settings > Conditional Formatting.... Here, you can create rules (e.g., emails from a specific sender, or with certain words in the subject) and apply a custom font size, style, or colour to them. This won't change everything, but it's great for prioritising or highlighting important messages with increased visibility.

Keyboard Shortcuts for Quick Zooming

Remembering keyboard shortcuts can save a lot of time. For quick zooming in the Reading Pane or when composing an email:

Hold Ctrl and scroll the mouse wheel up to zoom in.
Hold Ctrl and scroll the mouse wheel down to zoom out.
When composing an email, you can also select text and use Ctrl + Shift + > to increase font size or Ctrl + Shift + < to decrease it.

Consider a High-Resolution Monitor

If you frequently struggle with small text despite all settings, investing in a larger, high-resolution monitor can make a significant difference. A larger screen allows for higher scaling percentages without making elements feel cramped, providing more screen real estate and sharper text at larger sizes.

Reapply Settings for New Profiles or Computers

If you set up Outlook on a new computer, create a new Outlook profile, or reinstall the software, remember that your font preferences will likely revert to default. Make a note of your preferred font settings so you can easily reapply them, saving you time and frustration.

How Do I Increase The Font Size In Outlook FAQ

Q: Can I change the font size for just one specific email I'm sending?

A: Yes, when composing an email, you can select specific text and use the font controls in the "Text Formatting" group on the "Message" tab (or "Format Text" tab) of the ribbon to manually change its font size, style, and colour. This overrides your default settings for that particular text selection.

Q: Do these font size changes affect Outlook on my mobile phone?

A: No, these settings are specific to the desktop version of Microsoft Outlook on your computer. Mobile Outlook apps have their own interface and settings, usually controlled by the phone's overall display and accessibility settings rather than the Outlook app itself.

Q: Why do my emails still look small to other people even after I increased my sending font?

A: While you set a preferred font size for your outgoing emails, the recipient's email client and their personal display settings ultimately determine how the email renders on their screen. They might have their own small default font settings, or be viewing it on a device with a very small screen. You can't control how it looks on their end, but sending in a larger, standard font size generally improves readability for most.

Q: How can I reset all my Outlook font settings back to default?

A: There isn't a single "reset all fonts" button. You would need to manually go back through each setting you changed (Composing New Emails, Replying, Message List, etc.) and reset them to Outlook's original default values (e.g., Calibri 11pt for composing, or whatever was there initially). For interface fonts controlled by Windows, you'd revert your Windows Display Settings scaling to 100%.

Q: Can I make the navigation pane (where Mail, Calendar, People, Tasks icons are) larger?

A: The size of the icons and text in the main navigation pane (bottom-left of Outlook) is generally tied to your Windows Display Settings' scaling factor. Increasing the overall Windows display scale (as described in "Increase Font Size for the Folder Pane and Outlook Interface") will make these elements larger.
