UE5 bring static mesh close to the camera for inspection

Hi,

I have a SideViewCamera and when I click on a static mesh I want it to lerp position and scale towards the centre of the camera but I need a way to determine when it at the correct position and scale to take up the majority of the vertical or horizontal screen size.

Any suggestions on how to accomplish this. I have tried to having a mesh attached to the camera but it doesnt feel quite right

Thanks in advance
