For a start, some lines about sizes on vnc:
It starts with the vncserver: that has a size once it is started. On
M$Windows its the size of the console display, on unix, its the size you
give it with "-geometry XXXxYYY", the `vncserver` script has some build in
default wich you can change with any text editor, numbers at this point can
be rounded to a multiple of 4. This is all considdered pixel size, nothing
more, nothing less.

Then there is the viewer. That just gets the entire picture in its pixel
size. By default it matches every vnc-server pixel to a local pixel. If the
local display is smaller than the remote, then you should get scrollbars in
the vncviewer window.

Some vnc-viewers can zoom. That just removes pixels or doubles pixels,
depending in what direction you zoom.

Some vnc-viewers can go in full-screen mode. I don't know what they do with
the desktop geometry since I don't use it.

Back to your problem: It is true that a 24 point character is the same size
on the viewer display regardless of the vncserver-side geometry: 24 point is
mapped to a number of (24?) pixels. If the vncviewer does not zoom in any
way, every remote pixel is mapped on a local pixel, hence changing the
remote display size does not alter the local picture size.

If the viewer does not provide scrollbars if the vncsession does not fit in
the desktop window, that is an error/bug (or is it a setting?)

Waiting is never a solution, you have to step on the bus to get somewhere.
Asking directions here points you to: Check the settings of the viewer, Try
to find an other viewer with more options or just work with it.
