Of course, if you take it that way, there is nothing I can respond.

\newlength{\foo}

\settoheight{\foo}{$\dfrac{x}{x-1}$}

and just supposed I should eyeball things and replace \foo by
whatever would look good (\left.\rule{0mm}{4mm}\right| seemed good
enough in the event.)

But I did wonder about the need for

\newlength{\foo}

However, this being early (for me) morning, I didn't worry and was
happy just being able to control the height of the vertical bar.
