For this task, we can create a temporary window, and subtract its usable area from its size. This gives us the size (in pixels) used for decorations. Then we can query the screen size and subtract the size of those decorations.
For example:
<lang J> (".wd 'qscreen') -&(2 3&{) (wd'pclose') ]-/".'qform',:&wd 'pc a closeok; cc g isidraw; pshow; qchildxywh g'
1348 750</lang>
Here, we had a screen with 1366 by 768 pixels (width and height), and space for decorations subtract 18 from each of those dimensions.
