I'm not aware of any command or function in Emacs that adjusts text size
according to number of columns.  You've mentioned zooming in and out, by
which I assume you mean either `C-x C-+' and `C-x C-' or the
corresponding mouse binding <C-mouse-4> (i.e., holding down the Control
key while scrolling the mouse wheel).  But that command is
text-scale-adjust, which actually changes the height of the font, and
correspondingly the width, but AFAIK you cannot make it adjust the font
size by a specific number of columns.
