The topic of what a conventional sliding glass door size should be is a good one to ask, especially if you’re upgrading or building a new apartment.

Sliding doors provide a number of distinct advantages that are just too important to overlook. If you have a house near the ocean or a huge landscape, for example, you could prefer a transparent door that can provide a calming view to satiate your eyesight and calm your racing thoughts. The glass door also allows natural light to enter the building, brightening it significantly. So, let’s start with the most basic questions about sliding glass door dimensions and work our way through them one by one.


What Is the Dimensions of a Sliding Glass Door?

A standard glass sliding door measures 80 inches in length. The breadth, on the other hand, could range from 60 to 72 inches, depending on how much area you have to work with. The reason for retaining one standard measurement is to make things easier for owners who are just looking for a replacement and don’t want to go through the hassle of looking at all the possibilities. It’s also important to keep in mind that a sliding glass door can be made up of several different components, including a sliding glass window, a static glass installation, and several panels. When it comes to sliding glass door dimensions, it’s important to remember that different sections of the sliding glass door will have completely different measurements.

So far, the normal measurements for a glass sliding door have been determined to be 80 inches in length and 60 to 72 inches in width.

But what if your patio door is a multi-panel sliding glass door? In such instance, how wide should a sliding glass door be?

So, in the case of panel sliding doors, below are a few elements and measurements to be aware of. If you’re looking for a replacement or want to install a brand new glass door in your freshly constructed mansion, you’ll need the following information to get started.

A sliding glass door is one of the best features to add to your home if you want it to feel more like you’re on vacation. These let in more natural light and conjure up images of days spent lounging on tropical beaches in luxury.

One of the first things you’ll need to decide while shopping for sliding doors is how big you want them to be. The difference between a door that appears packed in at the last minute and a door that seems like it was always supposed to be there is choosing the appropriate sliding door measurements. Continue reading to find out how to choose the finest sliding door measurements for your home.


Taking Measurements of an Existing Door

It’s critical to have exact dimensions on the existing hole if you’re replacing an existing sliding door. Although most sliding glass doors are available in standard sizes, many customers choose custom-made doors. You’ll want to make sure your new doors fit snugly and that you know whether you’ll need them altered.

The first step in measuring your existing door is to take out the internal trim. This can help you get a better understanding of how big the door is. Make sure you take accurate dimensions and write them down for your door seller.

Three vs. two panels

Sliding glass doors are commonly available in two configurations: two doors and three doors. One door can move in front of the other to produce the opening with two-panel doors. The middle panel of three-panel doors is normally fixed, with the doors on each side sliding in front of it.

Two-panel doors are often available in one of three widths: five feet, six feet, or eight feet. Because door panels are typically three to four feet wide, three-panel doors are available in one of two standard widths. They’ll either be nine or twelve feet broad.



Sliding glass doors are available in a variety of heights. Your choice will be determined by the height of your ceilings. You want to make the most of the wall space, but you also don’t want to push a sliding glass door in under a slanted ceiling, which will make the room appear claustrophobic.

If your home has eight-foot ceilings, you’ll want to go with a door that’s little under seven feet tall. For this height, sliding glass doors come in two sizes: six feet eight inches and six feet ten inches. If your ceilings are ten feet high, you may wish to acquire sliding doors that are eight feet high.


It’s possible that bigger is better.

One of the most appealing features of a sliding glass door is the view it provides of the outside world. You want to be able to see as much of your view as possible, whether it’s a spectacular cliff-side perspective or lush backyard landscaping. As a result, some sliding door manufacturers have begun to produce doors that are twelve feet tall.

These wider doors can provide a breath-taking sense of openness and stunning views like you’ve never seen before. They do, however, have their own drawbacks; for example, they are more expensive than smaller sliding door options. Furthermore, because these doors are so enormous and heavy, producers have had to work hard to make them easier to move.


The Golden Ratio is a proportion that exists in nature.

There’s a number you should bear in mind when determining what dimensions to employ for your sliding glass doors: 1.618. This is the golden ratio, the most beautiful shape in all of mathematics. The golden ratio can be found in nature in many locations, but it can also help you choose the most attractive size for your sliding glass doors.

You should obtain a three-panel door that is twelve feet wide and six feet ten inches tall if you have an eight-foot ceiling. This will give you the golden ratio’s closest dimensions. To obtain the same look as ten-foot ceilings, get doors that are eight feet high and twelve feet wide.


How to Install a Sliding Glass Door in Your Home

Of course, the golden ratio is excellent, but the most important element to consider is how well the sliding door will fit into your area. If you’re installing the doors in a small location, you don’t want it to appear claustrophobic. Be honest with yourself about what will work in your space.

A sliding glass door should have at least a foot or two of clearance around the sides and top. It all boils down to how much natural light you want to let in and how much wall space you’re willing to give up.


Optional Extras

You can obtain custom-built sliding glass doors if none of the sizes we specified are a good fit for your space. You should expect a greater price for these, so plan accordingly. However, because you’ll be investing in a permanent element of your home, it can be worthwhile to spend the extra money to obtain exactly what you want.

If you do have a custom-made sliding door, make a note of the dimensions somewhere. You’ll need that information if you ever need to sell the house or if the doors need to be repaired.
