Door and pass-through openings
A door that sticks, drops or will not latch is almost never the door. It is the opening it was hung in.

Quick answer
What size rough opening does a standard interior door need?
The usual rule is the door width plus two inches and the door height plus two and a half, which allows for the jamb and shim gap on a typical pre-hung unit. But manufacturers vary and some jamb details want more, so the real answer is the rough opening the specific door you have bought calls for. We will frame to that figure rather than to the rule of thumb.
The work
What openings actually involves.
Framing an opening is arithmetic plus judgement. The arithmetic is the rough opening: the actual door width, plus the jamb on each side, plus the shim gap, plus the margin the hinge side needs. Get that wrong by half an inch in either direction and you either cannot fit the jamb or you are shimming out a gap too wide for the casing to cover. It is a small sum and it is got wrong constantly, which is why so many interior doors in finished basements never quite work.
The judgement is everything else. Which way should it swing, and into what — because a door that opens into a light switch or blocks a radiator is a framing decision, not a trim decision. Whether a pocket or barn door is better than a hinged one in a tight hall. Whether a pass-through wants a square head or an arch. Whether the opening needs a header at all, because a non-bearing partition over a wide pass-through still needs something to carry the plate above it even if it is carrying nothing else.
And then the limit. New openings in load-bearing walls, widening an existing bearing opening, and removing a wall to make a wide pass-through are all structural work. They need an engineer, a permit and a different trade. We will look, tell you what we think is bearing and what is not, and be clear about which side of that line your opening falls on — before you have paid anyone for anything.

What’s included
Everything the openings scope actually covers.
Written into the estimate, not assumed. If something on your job is not on this list, it gets priced and named before anyone starts.
Rough opening from the real door schedule
01Framed to the actual door and jamb you are using, including the shim allowance. We would rather see the door, the jamb detail or the order sheet than work from a nominal size and hope.
Headers, cripples and trimmers set properly
02A header sized to the opening with full-height trimmers and cripples above, so the plate above the opening is carried and the head of the opening stays straight when the board goes on.
Swing and clearance thought through
03Hinge side and swing direction worked out against switches, radiators, furniture and the next door along. A door that opens the wrong way is a framing decision and it is cheap to get right and expensive to change.
Cased openings and pass-throughs
04Square-headed or arched openings between rooms framed with proper returns and consistent reveal depths, ready for casing, so the opening reads as a designed aperture rather than a hole with trim round it.
Pocket and barn door preparation
05Pocket door cavities framed to the manufacturer's rough opening, and barn door walls given a header and continuous backing where the track lands. Sliding hardware needs more framing than people expect and it needs it before the board.
Clear word on what is bearing
06An assessment of whether the wall is bearing, stated before any work is priced. Where it is, we say so and stop — engineer and permit, then we can frame the non-structural part around it.

Openings questions
Not covered here? Call and ask — you’ll get a real answer, not a “depends on the job”.
In a non-bearing partition, yes, and it is a straightforward half-day job plus the drywall repair around it. In a bearing wall it is structural work needing an engineer and a permit, and we do not self-perform it. The first thing we do on this enquiry is work out which of the two you have, and we will tell you plainly either way.
In a genuinely tight space — a small bathroom, a narrow hall — it solves a problem nothing else solves, and modern hardware is far better than the rattling frames people remember. The honest trade-offs are that the wall it slides into cannot hold anything heavy, cannot easily carry electrical, and needs the cavity framed before the board. Where there is room for a hinged door, a hinged door is simpler and quieter.
The reliable indicators are which direction the floor joists above run, whether the wall continues down to a foundation or a beam, and whether anything lands on it from above. Those can usually be determined from the basement and the attic, which is where we look. Where it is genuinely ambiguous, the right answer is an engineer rather than a guess, and a guess is the expensive option.
