There is no rocket science involved in measuring for a door replacement. Whether you are measuring an empty door frame or an old door that needs replacing, it is a relatively simple process. All you need is a tape measure and the knowledge of how to use it for accurate measurements. You can measure the door in use, just the door frame, or the entire opening of the door.
To understand the measurements, you will need to have basic knowledge of the door’s construction. It will help you with how to measure the door for replacement.
There are two types of door replacement options available in the market.
Did you know you have the option to replace not just a door, but the entire door unit? These are called pre-hung doors. A pre-hung unit consists of a door hanging with hinges fitted in a jamb frame. A pre-hung door has two variants.
These units include top and side jambs without any door threshold, sill, or decorative trims.
Exterior pre-hung units come with a four-sided frame and a threshold. Most of them have exterior trims included with them. This exterior trim is a molding made of traditional thick wood, known as “brick mold.” However, you have a choice to use either a brick mold, or you can replace it and use a molding that suits your taste or need.
If you only want a replacement door, then you have an alternate option to get just that. These replacement doors are called door slabs and come without any hinges and jambs. However, do not confuse the door slab with the slab style door or slab door. The latter are doors with flat or dull sides and do not have decorative contours or panels.
The process of measuring a replacement door is similar in both interior and exterior doors. However, a pre-hung door requires additional measurements. It is critical to ensure the trim fits the opening for the sliding.
A rough opening is the structural opening for a door in the wall. Wall studs at the side, top, and sill at the bottom help create this opening.
It is commonly known as a door frame made of wood or a door to hang from it. In the case of an interior door, it consists of side jambs, head, or top jamb. In the case of an exterior door, it also comes with a threshold.
Interior door frames traditionally have “stops,” which are narrow strips nailed within the frame to create edges and the door closes against these edges. In exterior doors, jambs have built-in steps to serve as stops.
The door frame usually measures half an inch shorter and half an inch to three-quarter of an inch narrower than the rough opening. This measurement provides you room to fit the door frame into the rough opening and square it up before you can fasten it up. Once the door is in place, you can use decorative trim to cover the gaps between the frame and the finished wall and around the bride and frame. These trims are casting that need to be removed when taking measurements for a pre-hung door. You can leave them on in case you only need a door slab.
A pre-hung door comes with a fitted door; therefore, its measurement focuses mainly on the frame. The measurement includes the following steps:
This one is straightforward, as you only have to measure an old door.
