How to Measure Closet Doors?

It is wise to take at least two measurements, as a doorway may lean (a little bit) on either way.

It may be hard to find a door for an opening that is not square. You have two options in this scenario.

  1. Reframing the doorway is the first option. In this scenario, you have to cut and remove the existing trim and jamb. The corners and edges become square in this manner.

  2. The second option is easier. You may search for a door that fits into the existing perimeter. In this scenario, there may be some imperfections (gaps) in some areas. However, you may hide these imperfections using a few trims along the edges of a doorway.
