Framing a door can be a great DIY project, that is if done right.

Here are the steps that you can follow:

  1. How to frame a door

Buy your door first so you can measure it and base your frame from those measurements. You’ll also need 2×4 lumbers, a level, some nails, a circular saw, and a hammer or nail gun.

From your measurements, add two inches to the width and 1½ inch to the height to know the exact dimensions of your door frame.

  • Use a saw to cut a top plate with the same width as the rough door opening. Nail this piece into the ceiling joists. Do the same with the soleplate and attach it into the floor joists without nailing the part between the width of the door since you’re going to remove some of it.
  • Create your king studs by cutting four pieces of wood with the same height as the distance between the top and soleplate. Nail the two king studs against between the plates and against the sides of the opening. Install the other two with the same width as the door plus five inches.
  • Create your jack studs by cutting two pieces of wood that are the same height as the new door plus 1 ½ inch. Nail these parts to the two inner king studs.
  • Create a header by cutting two pieces of wood with the same width as your jack studs and nailing them together, after which you should nail that header to your jack studs.
  • Create cripple studs by cutting one or two pieces of wood with the same width as the distance between the header and top plate. Nail those studs in place.
  • Cut out the soleplate between the jack studs using a saw and you’re all set to install your new door.
  1. How to frame a wall with a door

If you’re extending space or building a basement or shed, you would need to build a wall with a door in it.

In that case, you would also need to know how to frame your door together with your wall. But before you do that, check your local building code to make sure that you’re complying with all the standard rules of building a wall with a door.

  • Start by measuring the length of the wall that you’d want to build and include the ceiling height in different areas of that wall. Find the shortest floor to ceiling measurement and use that as your reference in building your frame.
  • To know how many studs you’ll need to build the wall, divide that length by 16 inches, and add two studs for your “end studs.” Use 8-foot lumber for lengths 8 feet and below and 10-foot lumber for over 8 feet.
  • Take account of the materials for your door frame, which will consist of two king studs, two jack studs, and a header.
  • Cut your top and bottom plates following the length of the wall and cut all your studs according to the shortest ceiling measurement subtracted by the thickness of two plates.
  • Cut your jack and cripple studs according to the measurements of your door opening. Also, cut the header according to the same measurements of the frame.
  • Build your wall frame by putting the top and bottom plates side by side and mark both plates simultaneously measuring every 16 inches along the length for your studs. Also, don’t forget to mark the location of your door opening.
  • Separate both plates and put the studs between them according to your measurements. Attach all the framing members using a nailer to create your wall. Make sure that the jack studs have the correct distance for your door casing. Nail the king studs, jack studs, and header in position.

Finally, you can then position and attach the wall making sure that everything is fitted properly. Use a drill with a masonry bit to drill a hole for securing the wall with the door frame to the concrete floor.

After everything is in place, you can cut the bottom plate so you can already attach the new door.

What should the rough opening be for a 36 inch door?

Standard Sizes

A 36” x 80” pre-hung single door will use a rough opening of approximately 38-1/2” x 82-1/4” to fit. Always remember to square up your door before you nail the frame in place to assure it will close properly.

How do you frame a rough opening for a Prehung door?

Framing rough opening sizes are really quite simple. Just add 2″ to the width of the actual door size. You should add 2-1/2″ to the height of the actual door. This will give you room to space the door frame off of the sub-floor.

How much space should be between door and frame?

The frame should be 3/16″ wider than the slab (1/16″ clearance on the hinge jamb and 1/8″ clearance on the strike jamb) and tall enough (usually 1/4″ – 1/2″ taller) to allow 1/8″ clearance on the head jamb and allow the slab to operate without rubbing on any flooring.

How much clearance should a door have?

What is the ideal clearance between the door bottom and the finished floor? The ideal clearance, or height, of a door above finished flooring is 3/8 inch and certainly no more than 1/2 inch. The height of interior doors above finished floors can also be an issue.

How much smaller should a door be than the jamb?

Ideally, there should be a gap of about 1/8 inch at the top and along each side, and about 3/8 inch at the bottom.

What is the difference between a door jamb and a door frame?

A jamb is the flat surface that runs vertically up either side of the door frame. This is where the hinges are placed to hang the door, as well as the striker plate on the opposite door jamb which helps you to open, close and lock your door. The door frame is all the elements combined.

How much space should be between rough opening and door jamb?

There should be a 1/8” gap between the latch-side jamb and the door slab edge at the top and bottom of the door only. Drive a 3” installation screw through the vacant hole in each hinge, through the jamb, shims and into the stud.

How thick is a door jamb?

Standard interior door jamb thickness on pre-hung doors is 4-9/16 inches. The door jamb is the frame that installs in the wall and supports the door via hinges. This thickness is designed for installation in a standard two-by-four wall (constructed by studs that are actually 1½ inches by 3½ inches).

How do I measure door jamb?

How thick is an exterior door jamb?

The jamb is the outermost portion of the frame on the sides and top of a door system. Measure the thickest part of the jamb. Add 2 1/2″ (Frames generally measure 1 1/4″ thick each x2). Add 3/4″ to unit width measurement.

How do I install a door jamb?

Door jamb thickness is almost always 3/4 inch. Measure this by removing the casing from one side to reveal the side of the door jamb. Casing is easy to pry loose with a pry bar, or even a screwdriver. There will be a gap between the jamb and the rough framing.
