Keep aspect ratio?

I'm wondering how to keep an aspect ratio, IDK how to explain but like they say a picture is worth a thousand words(they are phones the black is the screen, and the green is the space that my game should use.) My games aspect ratio is 3:2:

 

Use two cameras, background "LetterBox"-camera just to draw back background (set clear flags to Solid Color) and Main camera for actual rendering. Then set the main camera dimensions accordingly:

Code (csharp):

1.  
2.  public void CalculateMainCameraDimensions()
3.     {
4.         // Maintain the 16:10 aspectratio using letterboxing (vertical or horisontal depending screen dimensions)
5.        
6.         if (LetterboxBgCamera.aspect < 1.6f)
7.         {
8.             MainCamera.rect = new Rect(0f, (1.0f - LetterboxBgCamera.aspect / 1.6f) / 2.0f, 1.0f, LetterboxBgCamera.aspect / 1.6f);
9.         }
10.         else
11.         {
12.             MainCamera.rect = new Rect((1.0f - 1.6f / LetterboxBgCamera.aspect) / 2.0f, 0, 1.6f / LetterboxBgCamera.aspect, 1.0f);
13.         }
14.          
15.     }
16.  

You can call this every frame and test it live in editor by changing game view dimensions....
