John is right.... I never assume that any stud is where is supposed to be... 16" centers is standard but unless I know fir certain I'm not going to put a hole in the drywall...

Like Amos said, buy a 10 buck stud finder...

BTW, too bad the name of this thread isn't more interestin' 'cause I think the ladies would be havin' a ball (no pun intended) with it...
