how wide is a double garage door

When selecting the right garage door for your home, understanding the standard dimensions can significantly influence your decision. Double garage doors, known for offering ample space for vehicles and storage, are popular among homeowners. How wide is a double garage door? The width of a double garage door plays a crucial role in not only the functionality of your garage but also in enhancing the aesthetic appeal of your home’s exterior. This practical guide aims to shed light on the standard dimensions of double garage doors to help you make an informed choice. Whether you’re building a new garage or considering a replacement, knowing the typical sizes available will assist you in planning your space more effectively.

Standard Dimensions of Double Garage Doors

Double garage doors are essential to any home garage, providing enough space for two vehicles to enter and exit comfortably. Understanding the standard dimensions of these doors can help homeowners make informed decisions when selecting the right garage door for their needs.


The width of double garage doors is the first consideration. Typically, the standard width for a double garage door is 16 feet. This measurement is spacious enough to accommodate two cars side by side, allowing for a comfortable margin of space between them and ensuring the doors can open without interference. However, widths can range from 12 feet to 18 feet, depending on the manufacturer and the homeowner’s specific requirements. It’s crucial to note that while a 12-foot door may work for smaller cars, larger vehicles like SUVs and trucks may require the more comprehensive option to fit side by side comfortably.


The standard measurement for double garage doors is usually 7 feet, comfortably accommodating most vehicles. Nevertheless, options are available up to 8 feet for those who own taller vehicles, such as vans with roof racks or trucks. It’s important for homeowners to consider the height of their vehicles when selecting a garage door to ensure it meets their needs without any issues.

Factors to Consider When Choosing a Double Garage Door

Selecting a double garage door involves more than just understanding the standard dimensions; several other factors play a crucial role in determining the right choice for your home.

Vehicle Size

The size of your vehicle is the most obvious factor to consider. If you own two large cars or anticipate switching to larger models, opting for a garage door on the wider spectrum is wise. Additionally, the height of the door should accommodate your tallest vehicle, especially if it’s equipped with top-mounted accessories that add to its height. This consideration ensures you will avoid issues with the garage door’s dimensions as your vehicle needs to evolve.

Space Restrictions

The physical space available on your property can influence the garage door size you can install. In urban areas or neighborhoods with smaller lots, space constraints limit your garage door’s width and height options. It’s essential to measure the available space carefully, including the surrounding areas where the door will open and operate, to ensure it fits well within the property lines and does not infringe on adjacent spaces or structures.

Personal Preferences

Lastly, personal preferences play a significant role in choosing a double garage door. This includes aesthetic considerations, such as the door’s material, design, and color, which should complement the overall architectural style of your home. Additionally, functionality preferences should be considered, such as the desire for insulated doors for climate control or specific opening mechanisms like manual or automatic. Understanding your preferences in these areas will help narrow the choices and guide you toward the garage door that best fits your lifestyle and home’s design.

In conclusion, the standard dimensions of double garage doors typically offer sufficient space for most homeowners’ needs. However, when selecting a door, it’s essential to consider the size of your vehicle, any space restrictions on your property, and your personal preferences regarding aesthetics and functionality. By considering these factors, you can ensure that the double garage door you choose enhances your home’s convenience, security, and curb appeal.

Tips for Measuring for a Double Garage Door Installation

Choosing the right size for your double garage door is fundamental to ensure both functionality and aesthetics. A timely measurement could lead to costly adjustments or replacements. Correctly measuring the space designated for your double garage door is the first step toward a successful installation.

Tools Required

Before embarking on the measurement process, gathering the necessary tools is essential. These tools will help you achieve accuracy and ensure that the process is smooth:

  • Tape measure: A long, flexible tape measure is necessary for precise measurements.

  • Notepad and pen: To record measurements and make notes during the process.

  • Level: Ensuring the header (the top part of the doorway where the door is installed) and the floor are level is crucial for proper door operation.

  • Ladder: In some cases, a ladder may be needed to reach the top part of the garage opening.

Step-by-Step Process

Measuring for a double garage door involves several critical steps. Each step must be followed carefully to ensure accuracy:

1. Measure the Width: Measure the width of the opening at the widest point. This is usually from the bottom of the door opening. Ensure you measure across the garage door opening, not the existing door (if replacing). Record this measurement in feet and inches.

2. Measure the Height: Next, measure the door opening height from the highest point of the floor to the bottom of the header. The door opening might be partially square, so measuring the height at different points is crucial to ensure accuracy. Use the smallest measurement to determine the door height needed.

3. Side Room: Measure the spaces next to the openings on both sides. This “side room” is necessary for installing the door’s vertical track. Typically, at least 3.75 inches on each side are needed.

4. Headroom: Measure the distance from the top of the door opening to the nearest obstruction (like a ceiling or a beam). This “headroom” space is crucial for installing the door’s horizontal track and springs. Around 12 inches is standard, but more might be needed for certain openers.

5. Backroom: Finally, measure the depth of the garage (from the door opening to the back wall). This “backroom” measurement helps determine the space for the door to retract or roll up. The required backroom is typically the door height plus an additional 18 inches.

The aesthetics of your double garage door significantly impact your home’s curb appeal. Today’s market offers various styles and materials, catering to diverse tastes and home designs. Understanding the available options can help you make an informed decision that complements your home’s architecture and meets your practical needs.

Traditional vs. Modern Styles

  • Traditional Style: Garage doors often feature raised panels, decorative hardware, and windows. These doors fit well with classical home designs and are available in various materials and colors. They can bring a timeless elegance to your home’s exterior.

  • Modern Style: Modern garage doors emphasize clean lines and minimalist designs and often incorporate materials like glass, aluminum, or steel. These doors suit contemporary homes and can be customized in various finishes and colors to match your home’s modern aesthetics.

The contrast between traditional and modern designs allows homeowners to align their garage door’s style with the overall look of their home, ensuring a cohesive appearance.

Steel, Wood, or Aluminum Options

Each material offers distinct advantages and can influence the door’s durability, maintenance, and price. Here’s a brief overview:

  • Steel: Steel doors are highly durable, low maintenance, and offer excellent insulation options. They can be painted to match your home and are available in various styles. Steel doors can mimic the look of wood without the associated maintenance.

  • Wood: Wooden garage doors offer a premium and natural look, adding warmth and elegance to your home’s exterior. They require more maintenance than steel or aluminum doors but provide unmatched aesthetic appeal. Wood is perfect for traditional designs but can be customized for a modern look.

  • Aluminum: Aluminum doors are lightweight, rust-resistant, and suitable for homes in humid or coastal regions. They offer a sleek, modern appearance and can include large glass panels to let in natural light. While not as insulating as steel, aluminum doors can be an aesthetically appealing, lower-maintenance option.

When selecting the material for your double garage door, consider your home’s architectural style, your aesthetic preference, your climate, and how much maintenance you are willing to perform. Each material brings unique features that enhance your home’s value and appeal.

Cost Factors to Consider When Buying a Double Garage Door

Choosing the right double garage door involves understanding the upfront and ongoing costs associated with its purchase, installation, and maintenance. While the size of a garage door significantly impacts its price, several other factors play crucial roles in determining the overall investment required. When buying a double garage door, let’s dive into two main cost areas.

Installation Costs

The installation process of a double garage door is intricate and requires professional expertise. Here are a few factors that can affect the cost of installation:

  • Type of Door: The material and design of the garage door significantly influence the installation expenses. For instance, while aesthetically pleasing, wooden garage doors can be heavier and more complex to install compared to their steel or aluminum counterparts.

  • Openers and Technology: Modern garage doors have various openers and high-tech features, including app-controlled operations, security cameras, and automatic lighting. Opting for these technologies can increase the complexity and, therefore, the installation cost.

  • Structural Modifications: Sometimes, installing a new double garage door requires structural changes to the garage. These could include enlarging the door opening or reinforcing the walls, which will increase the installation costs.

  • Labor Rates: Installation costs also vary based on the rates charged by the contractor. These can be influenced by the contractor’s experience, your geographical location, and the time of year.

You can better understand and compare the installation costs involved by getting several quotes from different contractors and asking for detailed breakdowns of their estimates.

Maintenance Expenses

After the initial investment of purchasing and installing a double garage door, you’ll also need to consider the ongoing costs of keeping it in good condition. Regular maintenance is crucial to ensure your door operates safely and efficiently over its lifetime. Here are some maintenance aspects to budget for:

  • Routine Inspections and Tune-ups: At least once a year, hiring a professional to inspect your garage door and perform any needed adjustments and lubrication can prevent costly repairs down the line.

  • Repairs: Over time, parts of your garage door, such as springs, cables, and rollers, may wear out and require replacement. The cost of these repairs can vary based on the parts and labor required.

  • Weatherproofing: Depending on your climate, you may need to spend on weatherstripping and sealing to prevent heat loss and water damage. This not only protects your garage but can also save on energy costs.

  • Upgrades: As technology advances, you can upgrade components of your garage door system for enhanced security, convenience, or energy efficiency.

Investing in preventative maintenance can extend the life of your double garage door and help avoid unexpected repair bills.


When deciding on the width and other dimensions for a double garage door, it’s essential to consider not just the immediate cost of the door itself but also the installation and ongoing maintenance expenses. Factoring in these costs will help you budget more effectively and choose a door that meets your needs and preferences without any surprising financial strain. Whether you’re prioritizing security, aesthetics, or technological features, understanding the full scope of your investment ensures that you’re satisfied with your double garage door for years to come.
