Can you change the font type and size on the Outlook app?

There is no way within the Outlook app on Android to customize the font type of composed emails. It’s a curious omission. If you need more control over fonts on Android, consider alternative Android email apps instead.

You can change the font size to an extent in composed emails by highlighting any text in an email you’re composing and selecting between Body, Subhead, or Title in the bottom bar. There is no granular control, so if you want your subheading to be a specific size, you’re out of luck.

However, you can change the font size displayed within the app by adjusting your Android phone’s system-wide font size. This is also possible on the iPhone. You can also change the display density in the Outlook app, which will, in turn, reduce the font size.

How to change the font density on the Outlook app

1. Tap your profile image at the top-left.
2. Select the settings cog in the bottom left.
3. Tap Appearance.
4. Select the Density tab.
5. Choose between Roomy (the largest font option), Cozy, and Compact (the smallest font option).
