How to Measure a Door? 

Before you can replace a door in your home or building, you must measure the width, height, and thickness of your existing door to get the right size for your replacement door. If you are replacing your existing door with a panel rather than a pre-hang, these are all the measurements you need to choose the correct size. Remember that the door measurement only includes the doorway, not the frame or opening.  

Measure your door from top to bottom for door height, left to right for door width, then measure door depth to determine replacement material thickness. If you have a door that won't fit into your frame or if you have a frame without a door, you can measure the door jamb to determine the door size you need. Find the width of the door jamb by measuring the top, middle, and bottom of the inside of the frame, and find the height of the door jamb by measuring from floor to top. The girder thickness can be found by measuring the beam between the stops and the back.
