Font size changes when replying to email in Outlook in Windows 10

When sending emails, it is important to format the message properly, including the font size. If the text is too small, it can discourage the recipient from reading the entire message. Some users of Outlook face a problem when they reply to any Outlook email – the font size becomes smaller. This problem mainly persists with Microsoft Outlook. The default email service sometimes shrinks the size of text when you reply to someone.

Font size changes when replying to email in Outlook

The problem isn’t just with the reply option, but with the Forward mode too. You can barely see and understand the text you have typed, even though the font size in your toolbar remains unchanged. To fix this, do the following:

Go to the File
Select Options
Choose Mail
Click Stationery & Fonts
When you reply to or forward a message, you can choose to include all the original message text, or just a portion of it.
Choose the font you want and then select the size. After that, click OK.

We’ll go over the above steps in more detail

Open Microsoft Outlook. Find the “File” tab on the Ribbon menu and click it.

Choose the Outlook Options from the list of options displayed. Under the Outlook Options window, switch to the Mail option.

The ‘Stationery and Fonts’ button under the ‘Compose messages’ panel lets you change the default fonts and styles, colors, and backgrounds. Then, switch to the ‘Personal Stationery’ tab to make further changes.

Under the “Reply or forwarding messages” section, click the Font button and select the desired size. The default is 11.

When finished, hit the ‘Ok’ button to save the changes and exit. You should not experience the problem hereafter.

To adjust your zoom settings in Microsoft Outlook: Open Outlook. In the bottom right corner of the Outlook window, find the zoom slider and adjust it to the desired position. This will apply to all other Microsoft Outlook replies, automatically.
