Wheelchairs require a minimum of 2'-8" CLEAR [which really means a 2'" door as the door itself has width which encroaches on the opening], laundry rooms typically require 28 doors [32"] as most laundry equipment requires the width to be introduced into the room, elevators require a 28 door [32"] for reasonable access and entry doors are typically a bit wider at 30 [36"].
A double door unit typically requires a bit more width as it has a center part called a T-astragal [this is the projection of the "usually" stationary door that allows for the "always" active door to have a positive stop against which to close]. Proper designing is not merely creating something that looks good on paper, it must translate to workable dimensions in the field, else the end product will be a disappointment and acrimony.
Rather than joy, it will be the overwhelming, though avoidable, status of the building process. Site by. By using our website, you agree to the use of cookies as described in our Cookie Policy Accept. Like viewing an iceberg - what you see is only part of the story!!!
Categories General 37 Guest Post Mark the rough opening of the door on your base plate and top plate, clamping their wide faces together for both convenience and accuracy and working horizontally on the subfloor to frame the wall containing the door. Make the marks 35 inches apart — 30 inches plus 2 extra inches to allow for the jambs of either a prehung door or your site-built jambs for a slab door, and an additional 3 inches for the thickness of the jack studs.
The pairing of the studs strengthens the door opening and prevents the wall from twisting. Mark only the top plate for the locations of the cripple studs that run every 16 inches on center from the top plate to the header. Place a small arrow or "V" pointing to the cripple-stud marks to distinguish them from the full-stud markings. Measure, mark and cut a pair of headers from the 2-by-8 lumber.
These will fit between the king studs, if the door is in a load-bearing wall. Alternatively, if the door is not in a load-bearing wall, use 2-by-4 lumber. For example, for a inch door in a inch rough opening, the headers will be 35 inches long to reach between the king studs and set atop the jack studs. Push the header against the top plate and transfer the cripple-stud marks to it, using a speed square.
For example, commonly available widths include 18, 20, 22, 24, 26, 28, 30, 32, 34 and 36 inches. Adjust a side-to-side unlevel floor by putting wood or asphalt shingle shims under the subfloor to level it. Make a similar adjustment if the unlevel condition is preventing the door from swinging open fully; you may have to raise the jambs to provide clearance, then shim the floor under the door.
