Standard Sliding Glass Door Size, Width, Dimensions

One of the top considerations when building a new house or renovating an old one is lighting. For many people, fancy light fixtures are enough, but others are beginning to consider natural lighting as the best option. And glass doors usually provide excellent natural light in any location.

If you are considering installing sliding glass doors, you must consider the standard size, especially as it applies to the house size and available space. You must also check the type of sliding glass door you want and whether or not your floor plan can accommodate it.

So, what is the standard sliding glass door size? This article explains the right size based on the door type. The various sizes will help you decide what works best for your house.

Sliding Glass Door Sizes Based on Type

Sliding Glass Door Sizes Based on Type

You must have the correct measurement for your doors before selecting any type, including sliding glass doors. You must also remember that the house type you have in mind or are already constructing is vital to the type you select.

There are three standard glass door sizes:

  • 92 inches or 243.8 cm
  • 82 inches or 208.2 cm
  • 80 inches or 203 cm

The most common widths of the doors can range from 60 inches or 152 cm to 72 inches or 183 cm. However, note that these varying sizes and dimensions can affect the price and house layout. In other words, it may significantly affect your budget and the result of the construction.

Every sliding glass door typically has two sections. You will find the sliding glass section, which is the part you open and close, and the fixed glass panel, which is the stationary part supporting the door. But some sliding doors have three or four panels, completely changing the size and dimensions.

Let’s discuss different sliding glass door types, from smallest to widest.

1. Pocket Sliding Glass Door

This type of sliding glass panel is popular for small houses, but bigger houses can also use it because of its space-saving feature. Architects and contractors like using them because they provide the natural lighting and the look of a larger floor space without compromising on space.

This door slides into a gap in the wall, leaving the entire door space open instead of taking up extra space on the fixed panel side. In other words, the sliding door does not feature a fixed panel side but has only one panel, which is the side that slides in and out.

A pocket sliding glass door typically has a width of 30 inches or 70 cm, although some can be 36 inches or 80 cm. So, this type is either 30 or 36 inches, with an opening height of approximately 80 inches. A contractor can slightly adjust these dimensions, although they are standard.

It is ideal for door spaces too small to hold the standard swinging door, such as patio doors. This glass door suspends from the ceiling and attaches to the wall on a track, so it easily fits into the custom hole in the interior wall when you open it.

2. Standard Two-Panel Sliding Glass Door

This type of sliding glass door is the commonest, and you will find it in many houses, including residential homes and apartments. The door can slide both ways, which means you can create an open door space on one side or another. Some two-panel door types can have a fixed panel on one side, meaning you cannot open it.

Another advantage of using this type of sliding glass door is the lighting it provides. Instead of getting natural light from one opening, you get a double dose with a better view. However, you must ensure you have the space and fit for the door for the best results, especially if you do not mind using extra space.

The standard size of this sliding door type can vary, but it is usually the 80-inches height seen with other glass door heights. But the width can be 60 inches, 72 inches, or 90 inches, translating to 152.4 cm, 182.9 cm, or 243.8 cm. These sizes are standard, making it easy to replace the doors when necessary.

3. Three-Panel Sliding Glass Door

Three-Panel Sliding Glass Door

A three-panel sliding glass door will provide better visibility, view, and lighting than its two-panel counterpart. The middle panel is the one that you can slide open, but you have the option of moving it to the right or the left, creating the opening space.

Another perk of this sliding glass door type is its close fit within the weather stripping and surrounding frame. It keeps the cold air and draught out when the weather is cold while keeping the cold air from the air conditioner within the room during the hot season.

It also fills every gap around the door opening better than other sliding door types. The standard door height is 80 inches, the same as the others already discussed, but there are various door widths:

  • 144 inches or 365.8 cm
  • 108 inches or 274.3 cm

As mentioned, manufacturers keep the size as standard as possible to make door replacements easy.

4. Four-Panel Sliding Glass Door

This type of sliding door is not common in many buildings, but it is getting more popular daily. It features four panels, with the middle two moving to create a wider opening than the standard three-pane model.

You can slide one middle panel to the left and the other to the right. That means you will have a much better view and lighting than those provided by the other types. Some four-panel doors can open so that all the panels slide together to the left or right instead of opening two at a time.

The standard door width is 108 inches or 274.3 cm, with a standard height of 80 inches like the other doors.

5. Stacker Sliding Glass Door

There are usually two movable glass doors attached to this type, and you can move them toward another pane that does not open. In other words, one glass panel slides in front of the second one, and both slide in front of the fixed panel, forming a stack of doors.

It creates a wider view and lighting without taking up more space than the standard three-panel door. The opening size is usually about 295 inches or 749.9 cm because of the number of panels. But the standard width can be 59 or 354 inches, depending on the panel number.

Standard Sliding Glass Door Size: Considerations

Standard Sliding Glass Door Size: Considerations

Several factors determine the type and size of sliding glass doors you use. The following are common ones to consider:

1. Dimensions

As with everything you buy, the price determines the choice you make. The same applies to sliding glass doors. The more elaborate the glass door dimensions are, the pricier the doors will be.

For example, the cost of buying and installing a three-panel sliding door is not the same as those of a pocket sliding door because of the dimensions.

2. Function

The effect and function you hope to get will determine the door size. For example, you may have a scenic view, and installing the door lets you enjoy it. Also, you may love painting, which requires bright light.

So, using sliding glass doors provide excellent lighting. Besides, these doors may be handy when you need more air than the fan provides in hot weather. Several other functions for a sliding glass door make it convenient for many homes.

3. Material of the Frame

Before deciding on the glass door size, you must check the door frame’s weather viability, durability, stability, and balance. These determine how long and well the door lasts, especially where it is frequently used.

A weak frame material may easily wear out with extensive door dimensions. Vinyl is a popular choice because of its low-maintenance nature and affordability. Besides, it holds up well under different weather conditions and comes in various colors.

4. Wall Thickness

The thickness of the wall must suit the door size to extend its durability. This is especially true if you use the pocket sliding door type. It must be sturdy and wide enough to hold the door type.

Weak walls may affect how long it lasts; you may want professional assistance if you are constructing or designing the house yourself. This ensures you use the correct frame and wall thickness to hold the sliding glass door type and size of your choice.

5. Glass Material

You must also consider the glass material when deciding the door size. The thicker the glass is, the less light it will provide, although the dimensions will change. Furthermore, the glass quality and energy efficiency are critical to your choice, particularly if the door faces outside. It must have the capacity to handle the weather without breaking or cracking.


Knowing the standard sliding glass door size that fits your house and style is crucial for getting the best results. Fortunately, getting the information you need is not difficult; it is even better that the size ranges are close together, so selecting one is not challenging.

However, remember the functions and style you want before picking a glass door based on its size. The wider the door is, the better the view and lighting, making the room look bigger and more elegant.
