Provide SizeChanged="Window_SizeChanged" just like below:

Then in your Window_SizeChanged method you can have the updated sizes as follows:

        private void Window_SizeChanged (object sender, SizeChangedEventArgs e)
        {

        var ah = ActualHeight;
        var aw = ActualWidth;
        var h = Height;
        var w = Width;
        Console.WriteLine ("ActualHeight(updated height value): {0}, ActualWidth(updated width value): {1}, Height(before size change): {2}, Width(before size change): {3}", ah, aw, h, w);
        }
//output:
// ActualHeight(updated height): 744, ActualWidth(updated width): 1382, Height(before size change): 600, Width(before size change): 1200
