If the studs are exactly perfect, you can install the prehung as
is. You are missing the shim clearance.

It would be normal to have the rough opening (stud to stud, no gyp
sheathing) 2" over door size. This would allow door, 2 pieces of
3/4 jamb stock, and 1/2' of shim clearance. In your circumstance,
this would be 38". You could probably drive the studs over the
1/4", but I would try it in the opening first.

You would not hang a door on studs. Doors are meant to be hung on
jamb casing


The rough opening width as it is now measures is 36-1/4", according to
the OP. The prehung door measures 37-1/2" wide. That is 5/4", or
1-1/4", wider than the rough opening. That is quite a bit larger than
1/4".

I bought a 36" pre-hung door, thinking that was what I needed to
fit an existing 36 1/4" opening that never had a door. About 2
minutes away from home, with the door lashed to the top of the
car, it suddenly occurred to me that maybe the door itself was
36" wide, and the frame was extra, so I checked before unloading
the door and found that it's 37 1/2" wide overall.

Obviously I could just take the door back without having to do a
whole lot of extra handling, but it seems that the next smaller
size is 32" rather than 34" and would be too narrow.

If I simply discard the frame with which the pre-hung door came,
how difficult would it be to hang the door in the existing
opening, and how much money am I likely to be wasting by having
bought a pre-hung door rather than a "bare" door? -- The prehung
doors were on sale, but I couldn't see what the regular price
was; the "bare" doors did not seem to be on sale, but I didn't
look at them, so I have no idea of the price.

Other suggestions?
