Prehung doors in 2x6 walls

First of all, I've never hung a door before, so forgive me of any blatant stupidity.
I'm building a small cottage in the back of my property. I built it with 2x6 walls. It's all framed, sheathed, roofed. I went and bought a 36" prehung door from Lowes, then realized that the frame it is hung in is sized for 2x4 walls. Does it matter? It looks like the inside of the frame (and hence, the barrels of the hinges) will be about 1" shy of the face of the inside wall. To me, this seems like a problem. Is the door going to bind against the corner of the opening every time it's opened? Are there specially prehung doors for 2x6 walls? Eventually, I will also get to this same question for some in-swing french doors, where I imagine the answer (either way) will be the same.

Thanks for any help!!

Prehung doors can be ordered to any wall thickness, but usually, 4 9/16 and 6 9/16 are standard sizes. I wouldn't be suprised if the stores you were in did not handle the doors that are the correct width for a 2x6 wall.

You either need to:

1) return the door and get one that has the right jamb width (for your 2x6 wall thickness) or

2) add a 2" extension jamb onto your 4 9/16 prehung door. The extension jamb must be added to the side of the door opposite the hinge, because the hinge must be installed flush with the wall surface, or else as you surmised, it will bind when it opens.

If you decide to go with the 2nd option, you can purchase jamb stock to match your prehung doors, and just rip it down to size. One 81" jamb will give you 2 pieces once it is cut, and they also make shorter ones that you can get to cut up for the top extension jamb.
