Down arrow width

Question

So, in winforms, each drop-down list has this little arrow on the right that tells the user about the drop-down list, like this:

Now, how do I understand how wide this figure is? The reason is that I use ControlDrawToBitmap, it doesn’t paint the text for the combo boxes, and I can redraw the contents, I just hit some of the arrows (which are drawn correctly).
