Good catch. Yes, a typo. I meant 83 3/4, not 79 3/4, for this situation. |

Hard to trim METAL! You will find they are all going to be a half inch smaller than the nominal size frown Then why is *bob's* (upthread) 36" (presumably closer than half an inch to 36!) Because the contention they're _all_ "nominal less half" is simply not so...some prehungs are less-quarter and it's certainly possible to buy and find full-width door slabs which will have finished openings "nominal plus" clearance rather than the door being smaller. The "less-half" varietal is probably the most common of new units available now, but it isn't unique and certainly wasn't in the past, either. -- |

I have anything from "right on" to a 1/2" smaller and one that is about 1/4" smaller (steel door so I know it wasn't modified). My guess is that manufactures make doors for standard rough openings and the thickness they choose for the jam determines the actual door size. (for PREHUNG doors) I am curious how building inspectors deal with clear opening sizes for accessible routes since even a full size door is smaller because of the stops. I expect lots of variation on *interior* doors. But, I figured exterior door would have far less wiggle room! Nope as I told you some several responses above...they build to a RO and the final interior opening turns out to be what it is--the two of -1/2" and -1/4" are pretty common for width but the length (height) is also dependent upon those factors plus how they design the threshold. If you're trying to order a door slab to fit an existing opening, see above as well, there's a whole lot more besides just the exterior dimensions to worry about, especially if you're talking steel, not wood, where field modification is much more of a trick...particularly things like number, size, placement and setback of hinges, hole locations, etc, etc., etc., ... You're missing the point. It doesn't matter whether I'm looking to replace just the slab (reusing existing frame) *or* replacing the entire frame (with a prehung unit) -- if the RO is sized too narrow!

(the ones for sale, not the ones you walk through at the front of the store) That will tell me what they *sell* but won't explain why the two doors I observed (different homes, different widths, different construction techniques) are "off". If all doors are 35.5, then you have determined that a nominal 36 door is actually 35.5. I find it unlikely a custom door is a half inch different. Modern doors are always about 1/2" narrower than their listed size. There has to be some gap around the door, and that 1/2" is your gap. The INSIDE of the frame is the listed size (32" 34" 36", etc). If you're replacing an entire door and frame, you need the OUTSIDE measurements of the frame, an you make your rough opening about 3/4" larger, so you can align the frame and apply the shims. Some OLD doors were the actual listed size, but not always.... (Of course back then, the frames had to be 1/2" bigger than the listed door size). |

(A neighbor's door is 31.5" wide which I would assume qualifies as a 32" door] Both are correct for the given situation. If you are actually considering a new door the best idea is to have the place that you intend to purchase the door have their guy come out and measure. Most will charge for this but if you make the door purchase with them they will deduct that charge from the purchase price and order (or take from stock if you are lucky) a door to suit your needs. A mistake in measurement by you *will* be expensive. If they make a measuring mistake then the onus on them. Hiring it out will get pricey. The buck will have to be replaced (to use a COTS door) *or*, a custom door ordered, *or* a custom jamb, etc. In either case, we're looking at a fair bit of labor (time) and folks tend not to like to work for free (or, for the sale of the door) If you just want to take a flyer and 'do-it-yourself' then also consider door height, left or right swing, hinge size and location and boring the door for lockset and dead bolt yourself or having that done for you. I'd originally considered just replacing with a prehung -- to eliminate all the "fitting". But, the RO isn't wide enough to "simply" do so. The next alternative was to leave the frame in place and swap the slab out. This would require drilling the door to fit MY frame (so, I don't save much on labor -- except I no longer have to remove the frame!) But, the 35.5" confounds on that score -- unless I start inspecting individual prehung offerings hoping to find a 35.5" door that I can REMOVE from its frame and coerce into *my* frame! Then, I've got a 35.5" door drilled for *it's* prehung frame that I have to HOPE I can fit to my EXISTING frame. (too many things have to fall into place for this to be a joyous outcome) |

Hey, I'm out of here. As I said upthread, I have no desire to play data collection grunt for armchair, remote "pondering" as to how I should proceed. Thanks for your time but the question asked has been answered. I can now look at ALL of my options and sort out how best for me to proceed without "try this" sort of advice. [No, I don't care to explain all the OTHER options that I have so someone else can comment on how appropriate they may or may not be.] Sorry, I don't mean to be "short" and I appreciate the comments -- from all. But, these things tend to drag on BEYOND what is necessary (at least what's necessary for *me* to sort out how to proceed). |

Another complication: we lived in Europe for a while courtesy of (er, at the order of) my employer at the time.
Those German doors did not just swing into the jamb. They overlapped. Twice. There was a double jog in the jamb and a double overlap on the door. Wish I could get one like that here. |

If he plans to replace just the door itself, then maybe his question is OK. If he is planning on replacing the door and the jamb, then I think that he should determine the RO measurements and then shop for a pre-hung door armed with that information. +1 |

Sometimes even we engineers need to do lab work, not count of design drawings... -- I'd just pull the trim molding off to see the RO. Assuming he's replacing the door, it has to come off anyhow. But then again, the scope of the actual project hasn't been stated. It's almost certainly a RO where you can find a replacement door to fit, there are probably a lot of choices. Yeah, me too. The hole thru the jamb isn't all that reliable in that you'll hit whatever blocking is there and not know for certain whether it's fill or actual framing...I was simply pointing out to OP that the best answer isn't necessarily the answer to the question asked and likely isn't going to come from analysis/documentation but experiment/observation instead. Of course, if he were to simply take existing slab measurements including those of other specifics outlined and went with those to the local purveyor of goods... -- |

If you didn't bother to read through almost two years of discussion, try this: "Typically the rough opening required when installing a prehung door should be sized 2 inches wider and 2 inches higher than the prehung door itself. For example a two-foot, eight inch (32) by six feet, eight inch high (80) prehung door, would require a rough opening width of 34 inches and a height of 82 inches." Your opening is too big for a 32" and too small for a 36". If it's plumb, you can most likely slip in a 34" prehung door even though the RO is a shade skimpy. |
