In respect to this, how do you measure the thickness of a door?

Hold a tape measure to the edge of the door and record its thickness. Measure this edge on the door frame (known as the jamb), as well. These numbers should be close to the same, but it can be helpful to know both of them. The most common thickness is 1.75 inches (4.4 cm).

  3. Set a miter saw at 45 degrees.
  4. Measure across the top of the door jamb.

Generally speaking, all interior doors have a standard width of 34 inches. This is for bedroom, bathroom, and hallway doors. A good way to visualize these measurements is to think of two people being able to walk through the door at the same time.

How thick is an exterior door jamb?

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). An alternate jamb thickness is 6-9/16 inches.
