In this guide, we’ll look at how to measure sliding glass door. So what are you waiting for? Keep on reading. 

What is a sliding glass door?

A sliding glass door is a form of sliding door where one or two glass panels move horizontally to open and close them. Because of their design, they are frequently utilized in areas where easy access and a lack of natural light are needed. Also, depending on their design, the panels will glide smoothly and can open partially and fully. This makes the modern architecture door an ideal choice among many buyers because of its streamlined design, functionality, and ventilation.


How To Measure Sliding Glass Door Accurately?

 The following are the steps you should take to obtain an accurate measurement:

Know the Information

Before starting your measurement, you must know the process. The first thing you need to do is research the standard measurements that you can follow. There are also other types of sliding glass doors that have a specific measuring process. For instance, patio sliding doors should always start their measurement from the inside edge to the outside. If you are also replacing your old sliding doors, the measurement should be taken before you remove the old sliding doors.


Prepare the Materials

The next thing you should do is prepare the materials you will need. Some of these materials include the following:

Tape Measure

You need a tape measure with at least 25 feet of length. With this length, you won’t need multiple tape measures to measure huge openings. 


Level

Using a level, you can estimate whether the door frame is diagonal or straight. With this equipment, you can get precise measurements. 


Paper and Pencil

This is basic equipment to record your measurements. This is important if you want a precise measurement, especially when incorrect marks arise. 


Screwdriver

This material is important to make an accurate measurement underneath the door frame. You can use this to remove moldings or hardware that might interfere with your measurement. 


Step Ladder

To measure the top points of the door area, you need to use a step ladder. This is true, especially if the door opening is large. 


Measure the Width

measure the width

After getting the things you need for measurement, you can begin measuring the width. Using the tape measure, measure the width of the opening from the left to right using a tape measure and record the measurement. You must include the rough opening, especially if it’s a double sliding door, where the siding to siding measurement is recorded. 

Additionally, you must subtract an allowance from the measurement. Approximately 20 mm (1 inch) must be reduced to the measurement because you will still add sealing to the door. 


Measure the Height

Measure the Height

The next step is to measure the height of the doorway. In measuring the height, you will have to follow the steps in measuring the width to ensure an accurate measurement. So, you will start by measuring the height from the top of the wall opening to the bottom. 

After doing so, you can first measure the height of the opening on the left side and record the measurement. Then, move to the height of the opening on the right side and record the measurement. If these two measurements vary, it is vital to choose the lesser value as the official measurement. Additionally, you must deduct at least 10 mm (0.4 inch) for the final measurement. 


Measure the Wall Depth

You also need to measure the wall depth. By doing so, you can guarantee that the frame fits correctly without protruding or being recessed. It is also best to account for any trim or molding because this will impact the door’s overall depth and appearance. 


Note the Floor Level

To ensure that the door will fit into the level surface, you must measure the floor level at various locations in the doorway. When the floor of the doorway is uneven, this might change the measurement and alignment of the floor. 


Measure the Rough Opening

This measurement step is crucial for new installations. The rough opening is the distance between the studs of the wall. With this, you must ensure enough space between the door frame and any shims. 


Recommendations on Choosing the Ideal Sliding Glass Door Measurement

The following are some of the recommendations you can follow:

Wall Strength

You have to ensure that the wall has enough strength to accommodate the weight of the sliding door. There are two common thicknesses, which are 10 cm and 12.5 cm. With this measurement, it would be enough to install your door. 


Door Size

You can get standard door sizes. However, many manufacturers allow you to customize the sizes to meet your needs and demands. If you are unsure of the measurement, you can ask them for guidance. They can certainly provide it accurately. 


Frame Size

The frame size can alter the measurement of the door. When designing and estimating your space, you need to account for the frame size or make adjustments to the measurement. This will ensure that you will have no problems when you install the door after. 


Conclusion

Now that you know how to measure the sliding glass door, you can easily obtain the measurement. This sliding door will not only look great but also be highly functional. In this regard, your next step would be choosing the high-quality sliding doors on the market.
