How to scale different GUI objects to fit screen size ANDROID

Hi, i was just wondering if there is an easy way to just auto scale all you GUI elements.
for instance I know when your creating an Rect you can just use Screen.width/2 and so on, but when it comes to gui text objects, scaling font, and gui textures etc. is there a way that you can just scale everything out?

-thanks in advance for any help!

void OnGUI()
GUI.matrix = Matrix4x4.TRS(, Quaternion.identity, new Vector3(1.0f * Screen.width / 1024, 1.0f * Screen.height / 768, 1));

//CODE of GUI… set button,score,texture
