UPDATE: To change the default font, font size and color, refer to our how to change the default font in Mail app in Windows 10 guide.
With the Mail app in Windows 10, you can read and respond to email messages from multiple accounts. It also allows you send and receive files and pictures as well.
While composing a new email message or replaying to a message, you might want to use a different font and font size than the default font. Choosing a specific font and font size is quite easy with the Mail app. In this guide, we will see how to change the font and font size in Windows 10 Mail app.
Remember that the Mail app doesn’t allow you to change the default font or font size. This means that the new font and font size is applicable only to the email message that you are currently composing. Also, there is no option to change the font or font size of texts in other areas of the Mail app.
It’s worth pointing out that the font that you choose for your new email message in the Mail app overrides the default font set in your email account. For instance, if you have set Calibri as the default font in your Outlook.com email account, it won’t be used when you choose a new font in the Mail app.
