How to Measure Patio Door?

1. Measure the Width of The Opening

The first step in measuring your patio door is to measure the width of the opening. To do this, use a long measuring tape and measure the length of the opening from the inside of the trim on one side to the inside of the trim on the other side.

Measure the width at the top, middle, and bottom of the opening and use the smallest measurement of the three. This will be the width of your patio door.

2. Measure the Height of The Opening

It is important to measure the height of the opening in order to ensure that your patio door will fit properly. To do this, you will need to measure from the top of the opening to the bottom of the frame.

Make sure that you measure in a straight line and not at an angle, as this will give you an inaccurate measurement. Measure the width of the opening in a similar manner, measuring from one side of the frame to the other.

Be sure to write down your measurements so you can refer to them when selecting a patio door.

3. Measure the Width of The Casing

After you’ve measured the length and height of your patio door, you’ll need to measure the width of the casing. To do this, use a tape measure to measure the width of each side of the casing, from the inside edge to the outside edge. Make sure to measure all sides, including the top and bottom.

If you are measuring a 2-panel sliding door, make sure to measure the width of each panel separately. Remember to take note of the measurements and write them down, so you’ll have them handy when you’re ready to purchase a new patio door.

4. Measure the Height of The Casing

To measure the height of the casing for a patio door, start by measuring from the top of the floor to the top of the casing. Take this measurement, then subtract the thickness of the casing from it.

This will give you the inside height of the casing. Finally, measure from the inside of the bottom of the casing to the ceiling. This will give you the total height of the casing.

5. Measure the Depth of The Door Wall for The Trim

Once you have correctly measured the height and width of the door wall, you will need to measure the depth. This is important for making sure that the trim you buy is the right size for the door.

To measure the depth, use a tape measure or a ruler to measure from the front of the door wall to the back. Make sure to measure from the deepest point of the wall so that you get an accurate measurement. After you have the measurement, you will know the size trim you need to buy.

Conclusion

Measuring your patio doors accurately is essential if you want to get the right fit. There are many different methods that you can use, so find the one that works best for you. If you are still unsure, there are professionals available who can help you to get the perfect measurements. Taking the time to measure your patio doors correctly will make sure you get the perfect fit and enjoy your patio doors for many years to come.
