Get Size of Sprite?

Hi, I need to get the size of the ‘background’ sprite in order to divide it into sections to know where to create UI elements and also place other sprites on top of it.

Any hints/tips much appreciated!

Actually now that I created a new Actor, placed my sprite in the actor, added a camera boom, it suddenly looks like I am able to do what I wanted by placing Plane components and stuff on the Actor

Is this the right approach? Previously I had a sprite on the level and a camera on the level.
