We're going to install a new linen closet off the hallway next to our recently(ish) remodeled bathroom. The wall in question is load bearing.

I know how to properly build out the King and Jack studs, and if this weren't load bearing I'd just put in cripple studs, but since this is load bearing I figure on installing sistered 2x? over the doorway resting on doubled up jack studs. The only question I have is - 2 by WHAT?

It's a 30" door if I recall correctly (it's reclaimed from another part of the house and I haven't measured it lately) so I'm thinking sistered 2x12's will be MORE than sufficient.

How many floors above this one? – Tester101 Jun 6 '14 at 13:46

International Residential Code 2012

Chapter 6 Wall Construction

Section R602 Wood Wall Framing

R602.7 Headers. For header spans see Tables R502.5(1) and R502.5(2).

Table R502.5(2)

So if you're on the top floor, you can use 2 2x4's (unless the building is 36' wide, in which case you'll need 2 2x6's). If you have a floor above, you'll need 2 2x6's (unless the building is 36' wide, in which case you'll need 2 2x8's).

Just the attic above, so perfect. I'll use x6 anyway just for overkill though. – The Evil Greebo Jun 6 '14 at 14:00
