The closet in my master bedroom is 10" deep and 7' wide with only one door (gotta love an old house!). I ripped down the entire front wall of the closet, and plan to put a new one at about 18", with two four-panel doors that open out from the center. I picked up two 24" doors at an architectural salvage. My two questions are: 1) I'm considering using either 2x3's or metal studs for the new (non-loadbearing) wall. Any compelling reasons to use one or the other? 2) Having never framed in a door, are there any "rules of thumb" for the size of the frame? Will 48 1/4" be wide enough for hinges and to allow the doors to swing open freely? Do I need an extra 1/2"? I am planning to have either magnets or some other mechanism at the top of each door to hold them closed (no moving parts at the doorknobs).
