Auto size shape layer to text

Size:

mLay=thisComp.layer("Text");

mRect=mLay.sourceRectAtTime();

mPadX=20; //padding width

mPadY=20; //padding height

X=mRect.width+mPadX*2;

Y=mRect.height+mPadY*2; //alternatively fixed value: Y=70;

[X,Y]

Position:

mLay=thisComp.layer("Text");

mPos=mLay.transform.position;

mRect=mLay.sourceRectAtTime();

mPadX=20; //padding width

mPadY=20; //padding height

cHalfX=thisComp.width*0.5;

cHalfY=thisComp.height*0.5;

X=mPos[0]-cHalfX+(mRect.width+mPadX*2)*0.5;

Y=mPos[1]-cHalfY+(mRect.height+mPadY*2)*0.5;

[X,Y]

You can literally find hundrerds of alternate examples, but here you go:

mLay(this Comp.layer("Text");

mRect=mLay.sourceRectAtTime();

mPadX=20; //padding width

mPadY=20; //padding height

X=mRect.width+mPadX*2;

Y=mRect.height+mPadY*2; //alternatively fixed value: Y=70;

If you have the code already, you can simply dial in a fixed value for the second paramater instead of the .height(). not sure what else you need to know.
