It's the same as the window title bar, IIRC it's the size of the screen font +3 pixels, so if you use the default Topaz 8 font, the screen bar will be 11 pixels high. This isn't guaranteed though, changing the appearance using VisualPrefs or other patches, or newer versions of the OS (e.g. OS 4) can and will change this, and so you shouldn't rely on the size being calculated like that. Instead, it's possible to query the screen's structure and determine the title bar height, so if your program depends on screen height, you can always adjust to match any screen.
