Measuring double doors for replacement involves determining the precise size needed for the new door unit to fit correctly into the existing opening. For double doors specifically, a key measurement is the combined width of both door slabs.
Essential Measurement for Double Doors
When measuring double doors, the primary focus is on the width of the two door slabs measured together. This combined measurement helps determine the overall width of the replacement door unit required.
According to the reference:
For Double Doors, measure the width of the two door slabs together. Example: If your door measures 35-7/8" wide and 79-1/2" tall, you'll be looking for a 36" x 80" door.
This means you need to measure the total width from the outside edge of one door slab to the outside edge of the other when they are closed. You also need to measure the height of the door slabs.
Step-by-Step Measuring Guide
Here's a simplified process based on the reference and standard practices:
- Measure the Width: Close both double doors. Measure the total width across the face of the two door slabs, from the outside edge of one door to the outside edge of the other.
- Practical Tip: Measure in at least three places (top, middle, and bottom) and use the smallest measurement to ensure the new door will fit.
- Measure the Height: Measure the height of a single door slab from the top edge to the bottom edge.
- Practical Tip: Measure in at least three places (left, middle, and right) and use the smallest measurement.
Example Measurement
Following the reference's example:
- Measured Width: 35-7/8 inches (This is the combined width of both slabs)
- Measured Height: 79-1/2 inches (This is the height of one or both slabs)
- Replacement Door Size Needed: 36 inches x 80 inches (Standard size rounded up from measurements)
This example shows how field measurements are typically rounded up to the nearest standard door size to select the correct replacement unit.
Why This Measurement Matters
Understanding the combined width and height of your existing door slabs is crucial for ordering the correct size replacement door unit. Double doors, sometimes called French doors, require careful measurement to ensure proper sealing, operation, and fit within the existing frame or rough opening.
Quick Measurement Summary Table
Measurement Type | How to Measure | Purpose |
---|---|---|
Combined Slab Width | Across face of both closed doors | Determines total door unit width |
Slab Height | From top to bottom of one door slab | Determines total door unit height |
Always measure carefully and consider consulting with a professional if you are unsure, as incorrect measurements can lead to significant installation issues and added costs.
