         screenType = "Slate";
     } else if (inches < 14) {
         screenType = "WorkHorsePC";
     }
     else 
     {
         screenType = "FamilyHub";
     }
     ApplicationDataContainer localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
     localSettings.Values["screenType"] = screenType;
 }

 

머 거창해 보이지만 실제로는

 

var bounds = Window.Current.Bounds;

 

이렇게만 얻어오면 된다.
