Fast Answer
- Zoom slider: Bottom-right corner of the reading pane, drag to 125% or higher
Before You Start
- Your Microsoft Outlook account, installed on Windows, Mac, or accessed through a web browser. The steps differ slightly depending on which version you use.
- Check your Outlook version to see which menus are available. Look under File, then Office Account, or click Help in the top menu.
- Confirm whether you want to change the text size for reading only, for writing new emails, or for all folders and menus permanently.
How To Increase The Font Size In Outlook
Use the Zoom Slider for a Quick Temporary Fix
Open Outlook and click on any message in your inbox. Look at the bottom-right corner of the reading pane. You will see a percentage number and a small slider bar next to it. Drag the slider to the right to enlarge the text in the email you are reading.
For a more precise adjustment, click on the percentage number itself. A Zoom dialog box opens, letting you choose from preset sizes like 125% or 150%, or type in a custom percentage up to 200%. This is the fastest way to see larger text instantly.
Change the Font Size for Reading Emails Permanently
To make every email you open display in a larger font, you need to change the default zoom level for the reading pane. Click on the View tab in the top ribbon. Then click on the View Settings button, which looks like a small spreadsheet icon. In the Advanced View Settings dialog box, click Column Settings. Look for the option that says Other Settings.
Inside Other Settings, find the section labelled Displayed Mail. There is a control called Zoom. Click the Select Font button and choose a font size that is comfortable for you, typically 14pt or 16pt. Click OK on every open dialog box to apply the change. Every email you open in the reading pane will now display with that larger font size.
Increase the Font Size of the Folder and Message List
If the sender names, subject lines, and folder names are too small, you can adjust the text size for the entire Outlook interface. On Windows, go to File, then Options. In the Outlook Options window, select General from the left sidebar. Look for the Personalize your copy of Microsoft Office section.
Click on the drop-down menu next to Office Theme and select the option that says Colorful, Dark Gray, or Black. Directly below this, you will see a setting for Office Background. Neither of these changes font size. To adjust interface text size, you must change your Windows display scaling settings, not Outlook settings.
Set a Default Font for All New Messages You Write
When you compose a new email, the text appears at a default size of 11pt in Calibri. To change this to a larger size, go to File, then Options, and select Mail from the left sidebar. Scroll down to the Compose Messages section. Click the Stationery and Fonts button.
A dialog box opens with three tabs: New mail messages, Replying or forwarding messages, and Composing and reading plain text messages. For each tab, click the Font button and choose a larger size like 14pt or 16pt. Click Set as Default, then OK. Your new emails, replies, and forwards will all use the larger font automatically.
Change Font Size in Outlook on the Web
If you use Outlook through a browser, the Zoom control works differently. Click on the gear icon in the top-right corner of the screen. Select Settings, then General, and click on Accessibility. You will see an option for Message density. Choose the Comfortable option to increase the spacing and text size in the message list.
For the reading pane, use your browser's built-in zoom controls. Press Ctrl and the plus key on Windows, or Cmd and the plus key on Mac, to enlarge everything on the page. The browser zoom remains active until you change it back, even after you navigate to different emails.
Increase Font Size for Printing Emails
When you print an email, Outlook uses the page setup defaults rather than the font size you see on screen. To print with larger text, click File, then Print. Before clicking the Print button, select Print Options at the bottom of the print preview screen.
In the Print dialog box, click Page Setup. Choose the Paper tab and notice the Scaling option. Set the scaling to 150% or 200% to enlarge the email text on paper. You can also go to the Format tab and adjust the font size directly if the email uses a single standard font.
Use the Reading Pane in Full View Mode
Sometimes the text appears small because the reading pane is narrow. Widen the reading pane by dragging the vertical divider bar between the message list and the reading pane to the left. This gives the text more space to expand and can make standard-size fonts look larger.
For an even better view, double-click on an email to open it in its own window. The message window uses a larger default font size than the reading pane. You can then drag the window corner to make it as large as your screen allows.
Adjust Font Size with the Mouse Wheel or Trackpad
If you prefer a hands-on approach, hold down the Ctrl key on your keyboard and scroll upward with your mouse wheel. Each notch of the wheel increases the zoom level by 10%. Alternatively, use two fingers on your trackpad and swipe up while holding Ctrl.
This adjustment works in the reading pane, the message list, and the folder pane simultaneously. The zoom level you set applies to the entire Outlook interface, not just the open email. You can quickly reset to 100% at any time by holding Ctrl and pressing the 0 key.
Set a Default Zoom Level for the Reading Pane
If you find yourself adjusting the zoom every time you read an email, set a permanent default. In the reading pane, click the percentage value to open the Zoom dialog box. Choose a percentage such as 125% or 150%, then click OK. When you close and reopen Outlook, this setting may reset.
For a persistent default, return to the View tab and click View Settings, then Other Settings. Look for the Zoom option and click Choose a default zoom level. Select your preferred percentage. Every folder in Outlook will use this zoom level whenever you switch between them.
Change Font Size for a Single Email Message
To increase the text size within one specific email without applying the change globally, use the Zoom feature on the Message tab. Open the email in its own window by double-clicking it. On the Message tab, locate the Zoom group and click Zoom. Select a percentage larger than 100%.
This action changes the display of the current message only. When you close the message and open the next one, the zoom returns to your default setting. This is useful for emails with very tiny print, such as forwarded PDFs or pasted web articles.
Reset or Adjust Zoom When It Is Stuck
If Outlook opens every email at a tiny size and the zoom slider does nothing, the custom zoom setting may be corrupted. Go to the View tab and click Reset View. This restores the default zoom level for the current folder. If the problem persists across all folders, close Outlook completely.
Right-click the Outlook icon and select Run as administrator, then try changing the zoom. On a Mac, go to Outlook Preferences, choose Read, and reset the Zoom control to 100%. If the font returns to normal, save your settings and restart the application.
Common Problems When You Increase The Font Size In Outlook
- Font size resets to 100% after restart: The zoom slider only applies to your current session. Set the default zoom level in View Settings, then Other Settings, or change the font size in Outlook Options to make it stick.
- Font size changes in the reading pane but not in the message list: The reading pane and message list have separate zoom controls. Use the zoom slider for the reading pane, and adjust the Windows display scaling for the message list text.
- Emails you write are still small even after changing the default font: The default font only applies to new messages, replies, and forwards. Existing draft emails keep the font you set when you created them. Create a new email to test the change.
- Printed emails cut off text on the right side: Increasing print scaling enlarges the text but may push it beyond the page boundary. Reduce the scaling to 125% or adjust the page margins in Page Setup.
- Outlook on the web does not save the zoom level: Browser-based Outlook follows your browser settings. Use the browser zoom controls and your browser will remember the level for that site on your next visit.
Advanced Tips For Increasing The Font Size In Outlook
- Use large fonts in Windows entirely: On Windows 10 and 11, go to Display Settings and set the Scale to 125% or 150%. This affects all applications, not just Outlook, so your email, calendar, and contacts all display larger text.
- Create a custom quick step to enlarge fonts: Go to Home, then Quick Steps, and create a new step that applies a larger font size to selected emails. When you run the quick step, the selected message text enlarges without affecting other emails.
- Modify the Normal template for consistent font sizes: In Outlook, click New Email, then switch to the Format Text tab and change the font size. Click Set as Default and confirm. This changes the default for your primary email account only.
- Use Mailtips for read alerts on small text: Outlook displays Mailtips at the top of the reading pane for emails that may have display issues. Enable this feature under Mail Settings to get warnings when an email uses very small fonts.
- Pair keyboard zoom with reading pane width: Widen the reading pane to at least two-thirds of your screen width and then apply the zoom slider. The combination provides the largest readable text without changing the actual font.
- Backup your settings before making permanent changes: Export your Outlook settings via File, Options, then Advanced, and select Export. This saves your current font and zoom preferences so you can restore them if a change does not work out.
