How do I know the current width of system scrollbar?

As you know, one can customize the width of the scrollbar width in Display Properties -> Appearance -> Advanced -> Item: ScrollBar. The default value is 17. However, I can't assume this is always the case, is it possible for me to retrieve this value?
