Text size too small in mail

Dear @Steve Saxon,

Good day, thank you for reaching out to Q&A Forum. From my research, this is a very common issue. It is often related to display settings within the email compose window. You can try the following approaches, starting with the quickest option:

1.Quick fix 

When composing a new email, hold the Ctrl key on your keyboard and scroll your mouse wheel upward to zoom in. You can also use the Zoom control, as suggested by the Q&A Assist above. This usually resolves the issue immediately if the text size was unintentionally zoomed out.

2.Set Default Font Size

1. In Classic Outlook, go to File > Options.
2. On the left, select Mail.
3. Click the Stationery and Fonts button.
4. Under New mail messages, click the Font button.
5. Set your preferred font (e.g., Calibri or Aptos) and Size (usually 11 or 12).
6. Do the same for Replying or forwarding messages.
7. Click OK on all windows to save.

This ensures new emails start with the correct text size.

I hope this information is helpful. Please follow these steps and let me know if it works for you. If not, we can work together to resolve this. Thank you for your patience and understanding. If you have any questions or need further assistance, please feel free to share them in the comments so I can continue to support you. I'm looking forward to your reply.

In Classic Outlook for Windows, there are two common places where text size can suddenly appear very small: the message body when composing, and the message list/reading pane. Try the relevant steps below.

1. If the text is small while composing a new email

Use the Zoom control for the compose window:

1. In the new email window, place the cursor in the message body.
2. On the ribbon, go to Format (or the formatting/Zoom option in the compose window).
3. Select Zoom.
4. Choose a higher zoom percentage (for example, 125% or 150%) and apply.

If the default composing font itself has changed to a smaller size, reset the default font:

1. Press Alt+F, T to open Outlook Options.
2. Use the arrow keys to select Mail.
3. Press Alt+F to open Stationery and Fonts.
4. In Signatures and Stationery, choose which default you want to change:
   • Press F for new mail messages.
   • Press O for replies and forwards.
   • Press N for composing/reading plain text messages.
5. In the Font dialog, press Alt+S to move to Size, then type a larger size (for example, 11 or 12) and press Enter.
6. Press Tab until OK is selected, then press Enter.
7. Back in Outlook Options, press Tab until OK is selected, then press Enter to save.

2. If the text is small in the message list or reading pane

If using the new Outlook for Windows interface, adjust the message list and reading pane text size:

1. From the menu, select View > View settings.
2. Select Mail > Layout.
3. Under Text size and spacing, choose Medium or Large.
4. Select Save.

To temporarily enlarge a specific email in the Reading Pane:

1. Select the email so it appears in the Reading Pane.
2. On the menu, select View > Zoom.
3. Use + to increase zoom (up to 200%) or - to reduce it.
4. Use Reset if needed.

If the issue persists only in certain folders, also verify that Windows display/text scaling has not recently changed, as that can affect Outlook’s UI text size.
