Not sure why TweenSize isn’t part of BillboardGui. All gui objects share UDim2 as Size already.

Because BillboardGui is a layer collector, not a gui object.
A layer collector contains gui objects. The purpose of it is to contain the gui objects, not to be one of them. Anything you’re hoping to accomplish with BBG:TweenSize would be better done by having a 1,0,1,0 frame as a descendant of the BBG, and tweening that instead.
