How do I know my game is the right size for the iPhone?

In Unity, navigate to Edit > Project Settings > Player

Select the correct option (tab) under Per-Platform Settings, then click on the ‘Resolution and Presentation’ tab , but most importantly, check the Other Settings tab.

Or : just set your game view to 3:2, or 4:3 (doesn’t work for certain GUI application methods/plugins)
