Doors – What size prehung door to buy

If you're having the same problem I had, and it's a case of rubbing but the door could be forced closed (so it's just slightly off), I just made a note of where it was rubbing with a bit of crayon (wipes off easily), then took a small hand plane to shave down that area slightly.

Unfortunately, I also made the mistake of passing off the plane to my house mate, who wasn't familiar with its use, and he ended up taking a chunk off of his bedroom door. I have no idea how he managed to do it. So, for using a plane -- you want long strokes, and try to shave the door off -- if it gets caught and starts splitting the grain, stop, move back further, and then lightly shave down past where you had the problem.

If the existing setup works, I don't see any reason why it wouldn't work with new doors instead. One down side to this setup though, is that doors without jambs aren't that secure and could probably be kicked in fairly easily. If it were my garage, and I didn't want a standard fold up door or a roll-up, I'd probably put in 2 larger barn style doors, or if you have the space, one of those sliding barn style doors that has an overhead track to slide on.
