How to Measure Your Door Properly

If you are looking to replace a door you currently have, measure the existing door from top to bottom. Continue by measuring the door from left to right. You also want to measure the thickness of the door. Most doors have a thickness of 1 ¾ inch. Your door shouldn't be too far from that measurement. It is also important to measure the width of the door jamb and the height and width of the frame. Be sure not to include the trim in your measurement.

The Rough-In Calculation Rule

Finally, you should add 2 inches to the width measurement of the door and 2 inches to the height for the doorway opening. This is called a rough-in measurement. A rough-in measurement applies whether or not you are using a pre-hung door.

Example: A 36" x 80" door requires a 38" x 82" rough-in space.
