The concept of "pitch" doesn't really exist for proportional fonts
(of which Arial is one instance), as in a proportional font 5 "m"s
might occupy much the same space as 10 "i"s.<br>

The vertical interline interval (called the "leading" in TeX) is in
normal circumstances controlled by a TeX variable \baselineskip, so
you could add some debugging code to tell you the current value of
\baselineskip — however, if any lines are excessively tall and/or
deep, TeX may ignore \baselineskip and honour some other parameters,
into which I will not go here ...<br>
<br>
LaTeX (which is what I assume you are using) does not expect you to
modify \baselineskip directly (it provides, I believe, alternative
control sequences which you <i>are</i> expected to use), but that
does not prevent you from interrogating \baselineskip if you need to
know the intended leading, from which you can then compute the
intended lines per inch. It will <i>probably</i> be of the order
of 14.4pt for a 12pt font (i.e., roughly five lines per inch) but
that statement comes with no guarantees ...<br>
