You could use the ApplicationView.PreferredLaunchViewSize Property to set the size of your UWP APP.

1. Set a minimum value for the size using ApplicationView.SetPreferredMinSize(Size) Method.
2. Set a value for the size of the app as you want by setting the ApplicationView.PreferredLaunchViewSize Property
3. Apply the size by setting ApplicationView.PreferredLaunchWindowingMode Property.

Please refer to the following code:

        public MainPage()
    {
        this.InitializeComponent();

        //set minimized size
        ApplicationView.GetForCurrentView().SetPreferredMinSize(new Size(200, 200));
        // change to smaller size
        ApplicationView.PreferredLaunchViewSize = new Size(400, 400);
        ApplicationView.PreferredLaunchWindowingMode = ApplicationViewWindowingMode.PreferredLaunchViewSize;
    }
