How To Measure For a New Door Set
Measure the height of the opening from the head of the doorway to the floor or sill. Make sure you take into account the type of flooring you have, especially if it has not been installed yet. Take measurements from three different places for each dimension and use the smallest. Take away 10mm from the final measurement.
Measure the width from wall to wall. Take three measurements across the top, middle and bottom of the walls, use the smallest measurement and take away 10mm.
Measure the thickness of the rough opening. It’s best to take two or three measurements for this also. Find the thickness which is the closest match for the door set you want. If there is any architrave or trim around the rough opening make sure you don’t include this in your measurement. Remember, exterior walls are usually much thicker than interior walls. You will then be able to purchase your new Door Casings & Linings.
