To measure for a replacement double entry door, you typically measure the existing rough opening in the wall. This ensures the new door frame will fit correctly.
Key Steps for Measuring a Double Entry Door Rough Opening
Measuring the rough opening is crucial for selecting or ordering a new double entry door. The reference video, "JELD-WEN Tip: Measuring for Entry Door Replacement," highlights the standard method.
Here's how to measure:
Measure the Width
Measure the horizontal distance of the rough opening. According to the reference, you should take horizontal measurements in three places across the width: at the top, middle, and bottom of the opening.
- Measure from one edge of the door frame to the opposite edge of the frame.
- Record the smallest of these three measurements. This is your effective width.
Measure the Height
Measure the vertical distance of the rough opening.
- Take measurements from the top of the rough opening down to the floor or the sill plate (depending on the structure). It's best to take measurements on both sides and possibly the middle.
- Record the smallest of these vertical measurements. This is your effective height.
Important Considerations
- Rough Opening: You are measuring the structural opening in the wall, not the size of the old door slab itself or the exterior trim.
- Take Smallest Measurement: Always use the smallest measurement for both width and height. This accounts for any inconsistencies or non-squareness in the opening and ensures the new frame will fit.
- Frame to Frame: As specified in the reference, measurements are taken "from one edge of the frame. To the opposite edge of the frame."
Summary of Rough Opening Measurements
Here's a quick look at the essential measurements needed:
| Measurement Type | How to Measure | Notes |
|---|---|---|
| Width | Horizontal, frame edge to frame edge, 3 places | Use the smallest measurement |
| Height | Vertical, top of opening to bottom, multiple places | Use the smallest measurement |
By accurately measuring the rough opening using these steps, you can determine the correct size requirements for your new double entry door unit, which includes the frame and door slabs.
