Please check ScrollBar style( stored in the general.xaml file ), the matched part like above screenshot is VerticalThumb , you could copy the following style in your page resource, and detect VerticalThumb load event, and get the ActualHeight property with following code.

private void VerticalThumb_Loaded(object sender, RoutedEventArgs e)
{
    var verticalThumb = sender as Thumb;

    var height = verticalThumb.ActualHeight;
}
