If you want to add some elegance to your place, a sliding glass door can be just the thing. But there are different types and sizes of sliding doors. Which one is right for you? Well, in this guide I will tell you what is considered a standard sliding glass door size for each type.

The standard size of a glass sliding door is about 80 inches tall. The width can vary though. Mostly, you will find sliding doors with widths between 60 inches to 72 inches. Two-panel sliding doors that are 80 inches x 60 inches are best for most.

This isn’t all though. There are some nuances here. If you want something larger, you can also go with a three-panel sliding door. But those are very large and cost more too. Let's take a deeper look.

What Is The Standard Size of a Sliding Glass Door?

The good thing about door panels is that they are made to a standard. This is done to make replacements easy. And it also makes choosing new doors convenient too. Before we get into more specifics, let’s check out some standard sizes.

Typically, sliding glass doors will be about 80 inches tall. This is the standard height for all sliding doors. But the width is a bit tricky. They can be from 60 inches to 72 inches.

There are other size options for sliding glass doors as well. You can choose from two types of sliding doors. A two-panel and three-panel sliding doors.

Two-Panel Sliding Glass Doors

Two-panel sliding doors are pretty common. And they look gorgeous too. It can elevate the space quite a lot if you install it correctly. So, what is the standard size? Well, two-panel sliding glass doors come in different widths. But the height is 80 inches tall.

When mentioning the width of a sliding door, the whole door is taken into account. I am talking about only the part you would be walking through.

The door opening can be a little less than half. Widths for two-panel sliding glass doors can be between 60 inches to 96 inches. Here is a more detailed table in inches and Ft measurements.

Two-panel sliding doors are more common, as I mentioned earlier. They will have a fixed section. And another part which you can slide to open or close the door. If you want something grander, three-panel sliding doors are your go-to.

Three-Panel Sliding Glass Doors

Next, we have the three-panel sliding glass doors. You can think of these as the step-up version of the two-panel ones. And they are quite huge. But if you have the space for it, these look downright majestic.

You will get a luxurious feeling. Anyway, three-panel sliding glass doors still have the same standard height of 80 inches. But there are some caveats here.

More on this a bit later. The widths are different. They can be 108 inches or even 144 inches. Which is around 9 Ft or 12 Ft respectively. Quite larger than their two-panel counterparts.

Sliding Glass Door Heights

Although 80 inches is a pretty standard height for sliding glass doors, you can find different heights as well. Other common heights are 82 inches and also 92 inches. So, you can imagine these look pretty awesome when installed.

It gives you a large opening which I think looks fantastic. But before you get starry eyed, you need to make sure to install the right size for your place.

Whether you are installing a sliding glass door for the patio or any other place, you need to think of the overall aesthetic. If you cramp a door too large just for the size and large open area, it might look weird and out of place. So, take a step back and think about which size works for you.


The size of the sliding glass door is not only important for knowing whether it will fit or not. It can also dictate the cost. Of course, larger sliding doors will cost you more. If you are looking for something more affordable, going with a standard 80 inches x 60 inches is a good option.

It will be cheaper and will fit in most places too. So, you have that peace of mind and will not second guess the decision. And I am talking about two-panel sliding doors here.

Apart from the size, there are a couple of other things that will come into play for the cost of a sliding glass door. Material and features are mostly the main things.

If you choose one with high-end materials, the cost will naturally be higher. It might be worth it though. When I am talking about material, I am referring to what the door frame is made of. So, you might just want to invest in higher-quality materials.

Then any kind of upgrades you get will add to the costs. You can think of these as customizations mainly. Say unique patterns, textures, or colored glass if that's something you fancy. There is even the option to use any kind of non-standard hardware for a customized experience.

But do not get turned away. These are just extras and not something you need. Standard two-panel sliding doors will still give you that awesome décor and luxurious feeling.

Wrapping Up

Alright, so there you have it. Hope this answers your question about what is the standard sliding glass door size. Although a big sliding door might seem intriguing, it can be costly. And if there is not enough space for it, you might even end up making your overall décor worse.

For most people, a standard two-panel sliding glass door that is 80 inches x 60 inches will work just fine. But here is the thing. Sliding glass doors are an investment. If you are going to get one, make sure you get the right one for your place and the look you are after. You won’t regret it.
