Blue in-swinging door opening into bedroom.
This in-swinging door is hinged on the right.

To ensure proper installation and use, we recommend you seek the advice of a professional. However, you can use the following method to obtain a rough size estimate:

  • Remove the interior casing and measure the width, then height, of the existing door frame.
  • Measure the door slab.
  • Measure the thickness of the wall to determine the jamb width needed.

Determine the door swing you’ll need (e.g., in-swing or out-swing, left or right). Door swing refers to the direction the door swings, based on the location of the hinges as viewed from the outside.
