I've thought of such things from time to time, and concluded that the
style authors have more knowledge of typesetting than I do, and that my
opinion of "more appropriate space" probably enjoys less acceptance than
their opinion.

However there is a case to make for being able to change it... you just
first need to ask yourself if you are sure that you know better than the
class designers. If you decision is based purely on "it's too wide" then
you probably don't know better and you should leave it alone.

Font sizes in Lyx and Latex are given names:

So first you need to think if you literally want "10.5pt" or if you want
to set the size of one of the name styles or sizes to 10.5pt.

You can mess with tie \fontsize{}{} command; insert this in your pre-amble:

\newcommand\sizetf[1]{\begingroup\fontsize{10.5}{12}\selectfont{#1}\endgroup}

then you can use the command

\sizetf{I'm in 10.5pt}

(I wish Lyx supported adding per-document layouts and elements in the
same way that it supports adding Latex commands in the preamble)

You probably want to read this:

And you may find it easier to use these if you define a lyx .module file
to go with them. Look at existing lyx module files to work this out, and
