Sliding Glass Door Measurement
Property owners planning to install a new sliding glass door will require precise measurements. When the property owner orders their door, the accuracy of the measurement eliminates complications. To obtain correct measures and eliminate errors, contractors follow stringent criteria.
Do sliding doors come in a standard size?
Depending on the area, a standard sliding glass door is 80 inches tall and 60 to 72 inches wide. Whether you’re building a new house or remodeling an existing one, a sliding glass door is a fantastic addition that gracefully allows fresh air and sunlight into your home.
Where Should You Begin Measuring?
- Determine the width of the door from stud to stud with a tape measure. The dimension reflects the existing door’s rough opening. The width of the door is measured at the top, center, and bottom of the aperture. Begin at the broadest accessible area of the side posts. The door width should be measured using the smallest of the three measurements.
- Then, determine the opening’s height. Begin with the far left, then the center, and finally the far right. The tallest accessible piece should be measured between the top or head jamb and the bottom or seal. The door height is determined by the smallest of the three measurements.
- The depth of the door aperture should then be determined. Without the trim, measure the width of the jamb. Measure the width of the current door frame from edge to edge. When ordering your sliding glass door, bring all three dimensions to your contractor.

What Factors Influence the Door’s Dimensions?
The exact measurements may be affected by the type of sliding glass door used.
To suit your choices, contractors installing the doors may need to knock out pieces of the surrounding wall. When establishing an accurate price for the whole installation, the contractor needs specific dimensions of the space.
How to Calculate the Size of a Screen Door
A screen door invites a pleasant breeze into your home while keeping annoying insects out on warm spring and summer days. When measuring a screen door, it’s important to get the height and width right, which includes knowing exactly where to lay your measuring tape on the door. To guarantee a proper fit, you’ll need to change the numbers slightly to account for the clearance between the door and the frame.
Choosing the Right Height and Width
- Determine the squareness of the door.
If it is level and even, a door is square, find the distance between the door’s bottom left and top right corners with a tape measure. Then, from the bottom right to the top left corner, take a measurement. The dimensions must be identical.
If the specifications differ by even a few millimeters, you’ll need to square the door and/or jamb before proceeding.
- Measure from the bottom of the sill to the underside of the top frame.
Pull the tape up to the underside of the upper door frame, starting at the bottom inside of the door frame. Just in case the frame isn’t straight, set it about 6 inches (15 cm) from the opposing door jamb. As the height of the door, jot down the number.

- Measure the frame’s width in 3 places.
Pull the measuring tape over to the opposite side of the door frame, about 6 inches (15 cm) from the top. After that, lower the measuring tape to about 6 inches (15 cm) above the bottom of the door frame and measure again from side to side. Finally, pull the tape measure across from one side to the other from the approximate middle of the door frame. The width of the door is the smallest measurement.
Hold the tape measure parallel to the ground for each of the measurements.
You don’t have to locate the door frame’s exact center. It’s a good idea to repeat the measures to ensure that the tape measure is roughly in the middle.
- For clearance, subtract 14 inches (6.4 mm) from each measurement.
When you’ve double-checked your measurements, make sure to account for the 1/8-inch (3.2 mm) gap between the screen door and the frame. You may get the right size for the door by subtracting 14 inch (6.4 mm) from both the height and width.
Sliding glass doors are ordered to replace existing patio doors or to complete the installation of a patio or pool. The stunning doors provide the homeowners with a picturesque view of their property’s outside while blocking damaging sun rays.
