How To Measure A Patio Door

Measuring a patio door is an important step in the process of replacing or installing a new one. By taking accurate measurements, you can ensure that the new door will fit perfectly and function properly. Here's a step-by-step guide on how to measure a patio door:

Step 1: Determine the type of patio door you have.

There are two main types of patio doors: sliding doors and hinged doors. Sliding doors move horizontally on a track, while hinged doors swing open like a traditional door. The type of patio door you have will determine how you measure it.

Step 2: Measure the width of the door opening.

For sliding doors, measure the width of the entire opening, including the frame. For hinged doors, measure the width of the door itself, not including the frame.

Step 3: Measure the height of the door opening.

Measure the height of the opening from the bottom of the threshold to the top of the header. For hinged doors, also measure the height of the door itself.

Step 4: Measure the thickness of the wall.

For sliding doors, measure the thickness of the wall where the door will be installed. This measurement will determine the type of door frame you need. For hinged doors, you don't need to measure the thickness of the wall.

Step 5: Add extra space for the door frame.

When ordering a new patio door, you'll need to add extra space for the door frame. For sliding doors, add 2 inches to the width and height of the opening. For hinged doors, add 3 inches to the width and height of the opening.

Step 6: Double-check your measurements.

It's important to double-check your measurements before ordering a new patio door. Make sure that the width, height, and thickness are all accurate. You can also have a professional measure the door opening for you to ensure accuracy.

By following these steps, you can accurately measure a patio door and ensure that the new door will fit perfectly and function properly.
