What you call "splitted views" are called "windows" in Emacs.

The font zooming I cited changes the size of a frame's default font. But you can
use other fonts anywhere you want. You would need to do some Emacs-Lisp coding
(unless someone else has done it), but you could use a different font in
different contexts (e.g. some window). However, there is no such thing as a
window's font, the same way there is a frame's font, so I don't think that what
you want would be straightforward.

If you use one window per frame (e.g. non-nil `pop-up-frames'), then you can
"have a view of a file in a smaller font" while the other frames (e.g. other
files) remain at the same font size. IOW, if you use Emacs frames the way you
are now using Emacs windows, then you can have what you want immediately. If you
stick to Emacs windows, then you will probably need to do some work to get what
you want.
