how can i magnify text in email without changing the font

[Scooter]

the text in my email (both incoming and newly created) seems to have gotten
smaller even though I haven't changed the font or any other settings I can
think of.

If you hold down the Ctrl key and scroll up and down, it will change the size.

Sounds like you're using Word and changed the zoom factor.
