How to Enlarge Email Font for Reading in Windows Mail: FAQ

Will Mail for Windows remember the zoom level?

No, you have to zoom in every time anew—or, of course, use Windows preferences to change the display font size.

Will changing the Windows zoom level make text bigger as I draft emails in Mail?

Yes.

The general Windows text zooming (or all-around interface scaling) will make text in emails bigger as you write them, too.

Note: This will not change the email’s font size for the recipient.

Can I enlarge the interface only for Windows Mail?

No.

You can change the interface size and zoom level only across all Windows applications and the operating system itself. You can, however, zoom in to a message’s content right in Mail for Windows.
