Door Rough Opening Dimensions


Since the 70's, I've framed (or had framed) door rough openings 2-1/2" over. But jamb stock seems to have evolved from a full 3/4" to 5/8" thick or even less nowadays. Thinking of going to only 2" over. What are your practices?

Re: Door Rough Opening Dimensions


I always get the product info on the door used Before rough and use that, plus shimming.

Likewise, learned at 2 1/2" and like it that way. This gives plenty of leeway to make the fit perfect plumb and shift to desired centering. Of course, we use mostly wider casings, 3 1/2" or larger, so the gap is always well covered.

Are you saying a 2'-8" door isn't always exactly 32" wide in your area? That thought never occurred to me. I can understand with windows - they're either actual or 1/2" under callout depending on the manufacturer.

Re: Door Rough Opening Dimensions


Our interior doors get framed door size plus 2 1/4. Our suppliers doors are a full 36 or 32 plus reveal and they still use 3/4 jambs so 2 inch over gets a little tight at time. For exterior doors typically they are 2 1/4 over also per the ro specs from manufacturer.

I have always framed 2" over. It seems to work out pretty good.

Re: Door Rough Opening Dimensions


I guess I should have prefaced my question with a recent experience with some volunteer work for H4H. I was assigned to hang six doors in the three bedrooms. The casing was the tiniest stuff I've ever seen - 1-13/16" wide.

Re: Door Rough Opening Dimensions


I frame 2" over most of the time, but if I'm not rushed and the planets are in proper alignment, I do 1 3/4 just because I can.

Re: Door Rough Opening Dimensions


In GENERAL.....2". Exterior doors I go 1/2" wider, double doors 2-1/2, bypass actual to + 1 depending on the casing. 2-1/2 on the height every time. Lots of other variables like handicap accessible.

Re: Door Rough Opening Dimensions


I like 2 1/2. 2" is too tight, it only leaves about a 1/4 and that's too small to get the spray foam nozzle into.

I don't work on houses, commercial only. So yes I have made the mistake of the RO being to big or to small by using some generic addition. Never again. It doesn't take all that much time to find out the product info before hand.

I actually don't even remember the last time I installed a 2-8 door, maybe on a closet somewhere but everything is 3-0+ out here because of ADA.

Re: Door Rough Opening Dimensions


I go with 2 1/2"(width and height) on exterior doors and 2" on interior doors, usually allows ample shiming room

Re: Door Rough Opening Dimensions


It depends on how plumb your walls are.

If they are real good 2" is enough.
I used to do 2 1/4, but since I started doing trim behind my framing ,I have cut it down to 2"
