Depends on what you are hunting.
I like smaller 6" or 7" height for deer - just enough to get gun out window and clear view for scope.
I like 12" tall for night time pig hunting to allow more open view for scanning and shooting with NV.
Width according to blind size but like to leave some wall to hide behind and help eliminate "skylighting" by daytime game animals.
