Re: 25 lb mirror in drywall
50lb picture hanger and you should be good. Do you have a stud to hang from or is it going to be just in the drywall? If no stud to nail to then you may want to have 2 "hanging spots" in the wall and run 2 tiny eye bolts in the back of the mirror and use some wire between the 2 hooks and hang it that way. Also if there is a female involved with this project you need to struggle as much as possible and not make it look easy or you will be doing more then just hanging picture. I get to hang a new light today because I'm so handy.
