Unity Engine

Hi everyone,
suppose I have a rectangular (width more larger then height) Texture to use as background…I want to position my camera in a way that at the start of the game the whole heigth of background is visible indipendently by the resolution of mobile devices…
Maybe I must set camera.size…but how I can achieve my goal??

Thanks!!!

In orthographic camera type, camera size = distance from center of the screen to top or bottom edge of the screen.
So if you have plane with height 10, for background, setup your camera size at 5
