Need name suggestion for the axis controlling apex in variable font

Hello TypeDrawers!

This is my first topic here, hopefully I'm doing it right.

Currently I am playing with variable font format and want to add an axis controlling the middle apex especially on M and W.
I try to create something like this:

What's the best name for this axis? Is "Middle apex height" right?

Any suggestion will help.

Thank you!

    Crotch?

    An “apex” is at the top, like the join at the top of /A or perhaps the one in the middle of /W. “Crotch” is the opposite, the center join in the /M, but because of its particular anatomical meaning, is arguably not an ideal word to use in an interface. Also, if the middle part of the /W is also adjusted downwards, it is no longer an apex, yet still arguably not a crotch.

    “Vertex" is an appropriate word that would apply to the center junction in both /M and /W.

    waistline?

  • Depth? Cleavage?
  • waistline?

    To me, that means primarily the height of the traditionally mid-height things, such as the crossbar on H, centre bar of E, and possibly the middle bits of P, R, G, F as well.

    I was thinking the middle bits of the M and W where all hell breaks loose ;-)
  • Center joint/break?

    Since it seems to be only relevant to M and W, there is more clarity in mentioning them than in any other words you choose. So call it "M-W Center Depth" or similar.
    I do believe "depth" is more descriptive than "height" here because it's a matter of how far the angle plunges into the letterform, in either direction. "Height" implies distance above the baseline, and I assume that you aren't making it so that setting a "low" center is deep for M and shallow for W.
  • While the term cleavage seems good🙂🙂🙂, I think vertex depth describes it well!

    Yes, I agree with you. Depth is the better term I think, and I am planning to make it clearer for the user by adding (M,W,w) after "Vertex Depth".
