A 2-panel sliding glass door is a popular choice for homeowners looking to improve the flow of light and air in their living spaces. With its sleek design and energy-efficient properties, it’s no wonder that these doors have become a go-to option for many modern homes.

One of the most important aspects to consider when purchasing a 2-panel sliding glass door is its width. In this comprehensive guide, we will explore the standard widths of 2-panel sliding glass doors, factors that influence their size, and how to choose the right width for your home.

Standard Widths of 2-Panel Sliding Glass Doors

Sliding Glass Door Dimensions

2-panel sliding glass doors are typically available in a range of standard widths. While there is some variation among manufacturers, the most common widths for these doors include:

  • 60 inches (5 feet)
  • 72 inches (6 feet)
  • 96 inches (8 feet)

It is essential to keep in mind that these measurements refer to the overall width of the door, including both panels. Each panel will usually be half the total width. For example, a 72-inch wide door would have two 36-inch wide panels. These standard sizes are designed to fit most residential door openings and can be easily customized to meet your specific needs.

Factors Influencing the Width of a 2-Panel Sliding Glass Door

Sliding Glass Door Sizes

Several factors can influence the width of your 2-panel sliding glass door. Some of the most common factors to consider include:

Existing Door Opening

The size of your existing door opening will determine the maximum width of your new sliding glass door. Measure the width and height of the opening to determine the appropriate size for your door.

Space Constraints

The available space around the door opening will also impact the width of your sliding glass door. Ensure that you have enough space on either side of the opening for the door panels to slide freely.

If you require a specific size that is not available in the standard widths, many manufacturers offer customization options. Keep in mind that customized doors may come at a higher cost and may require longer lead times.

Local Building Codes

Depending on your location, local building codes may dictate the minimum and maximum widths for sliding glass doors. Be sure to check with your local building department before making a final decision.

Selecting the perfect width for your 2-panel sliding glass door will depend on your specific needs and preferences. Here are some tips to help you make the right choice:

Evaluate Your Needs

Consider how you plan to use the sliding glass door. Will it serve as a primary entrance or simply provide access to an outdoor living area? Larger widths are often more desirable for main entrances, while smaller widths may be suitable for secondary access points.

Assess Your Home’s Style

The width of your sliding glass door should complement the overall design of your home. Wider doors tend to create a more modern and open feel, while narrower doors may be better suited for traditional or smaller homes.

Consider Energy Efficiency

Wider sliding glass doors can allow more natural light and fresh air into your home, reducing your reliance on artificial lighting and air conditioning. However, they may also result in more heat loss during the winter months. Be sure to choose a door with energy-efficient glass and a high-quality weatherstripping system to minimize heat transfer.

Installing Sliding Glass Doors

Factor in Installation Costs

Larger sliding glass doors may require additional structural support and could result in higher installation costs. Be sure to consult with a professional contractor to determine any potential cost implications associated with the width of your door.


Wider sliding glass doors can make your home more accessible for individuals with mobility challenges, such as wheelchair users or those with limited mobility. Ensure that your chosen width meets any accessibility requirements you may have.


While wider sliding glass doors can provide a more expansive view and increased natural light, they may also be perceived as a potential security risk. To mitigate this concern, invest in a door with a robust locking system and consider additional security measures, such as security bars or an alarm system.
