[Tex/LaTex] \perp and \parallel with equal height


I'm looking for a way to get symbols for perpendicular and parallel with an equal height. I want to use the symbols as a superscript to a function like


However, it looks kind of awkward since the two symbols are not displayed at the same height (the parallel sign is way larger). If I use


the symbols have approximately the same height but are not aligned properly in the vertical direction.

Update: I found out that


produces what I'm looking for. Still this is kind of a hack and more consistent solution would be really appreciated.

I suggest you construct a symbol using vertical rules. One version that will adapt itself to different math modes is

\newcommand{\myparallel}{{\mkern3mu\vphantom{\perp}\vrule depth 0pt\mkern2mu\vrule depth 0pt\mkern3mu}}

which you can use as


The height of the \vrule here automatically adjusts to the height of \perp, setting the depth to 0pt makes it fit with the base of that symbol too.
