How To Measure Patio Door

Measuring a patio door correctly is essential for ensuring a perfect fit when installing a new one. Here's a step-by-step guide to help you measure your patio door accurately:

Step 1: Determine the Type of Patio Door

There are two main types of patio doors: sliding and hinged. Sliding patio doors consist of two or more panels that slide horizontally, while hinged patio doors open and close like a traditional door.

Step 2: Measure the Width

For both sliding and hinged patio doors, measure the width of the opening between the two jambs (door frames). Measure from the inside edge of the left jamb to the inside edge of the right jamb. Record this measurement in inches.

Step 3: Measure the Height

For sliding patio doors, measure the height from the top of the threshold (bottom track) to the top of the head jamb (top track). For hinged patio doors, measure the height from the top of the threshold to the top of the head jamb.

Step 4: Measure the Rough Opening

The rough opening is the opening in the wall where the patio door will be installed. Measure the width and height of the rough opening. This will help determine the size of the patio door frame you need.

Step 5: Determine the Threshold Type

There are two main types of thresholds: zero-threshold and raised-threshold. Zero-threshold doors are level with the floor, while raised-threshold doors have a raised lip. Measure the height of the threshold to determine which type you have.

Step 6: Measure the Jamb Depth

The jamb depth is the thickness of the door frame. Measure the depth of the jamb from the inside edge to the outside edge. This will help determine the thickness of the patio door you need.

Step 7: Other Considerations

In addition to the basic measurements, there are a few other factors to consider when measuring a patio door:

Overlap: Measure the overlap between the door panels on sliding patio doors.
Handle Placement: Determine the desired placement of the handle on hinged patio doors.
Screen Size: If you plan on installing a screen door, measure the size of the screen opening.
