Here are the primary purposes for which garage doors are designed:

1. Vehicle Storage and Protection:

The primary purpose of a garage door is to provide a secure and enclosed space for the storage of vehicles. Garage doors shield cars, motorcycles, bicycles, and other vehicles from the elements, such as rain, snow, sun, and debris, helping to preserve their condition over time.

2. Security:

Garage doors are a critical component of home security. They act as a barrier against unauthorized access, protecting the belongings stored inside the garage, including vehicles, tools, and other valuable items. Many modern garage doors come equipped with advanced security features like smart locks and alarms.

3. Convenience and Accessibility:

Garage doors offer convenience by providing easy access to the garage without the need to manually open and close a door. Automatic garage door openers allow homeowners to operate the door with the push of a button, enhancing convenience and saving time.

4. Enhanced Curb Appeal:

Garage doors contribute significantly to the overall aesthetics of a property. They are a prominent feature that can enhance or detract from the curb appeal of a home or business. Many homeowners choose stylish and well-designed garage doors to complement the architectural style of their property.

5. Versatility in Design:

Garage doors come in a variety of designs, materials, and finishes, allowing homeowners to choose a style that matches their preferences and complements the overall design of the property. This versatility in design contributes to the visual appeal of the entire structure.

6. Temperature Control:

Insulated garage doors help regulate the temperature inside the garage. This is particularly important in regions with extreme weather conditions. Insulation can help keep the garage cooler in hot weather and warmer in cold weather, creating a more comfortable environment.

7. Storage Space Extension:

Garages often serve as additional storage space for items such as tools, outdoor equipment, and household items. Garage doors provide easy access to this storage space, making it convenient for homeowners to store and retrieve items as needed.

8. Property Value Enhancement:

Well-designed and functional garage doors can contribute to the overall value of a property. They are considered a key feature in real estate, and high-quality, aesthetically pleasing garage doors can make a positive impression on potential buyers.

9. Work and Recreational Space:

Garages are frequently utilized as workspaces, hobby areas, or recreational spaces. The design of garage doors allows for flexibility in using the garage as an extended living space, providing versatility for various activities.

In summary, garage doors are multifunctional elements that go beyond their basic purpose of securing vehicles. They contribute to the overall safety, convenience, and aesthetic appeal of homes and businesses. The design and features of garage doors continue to evolve to meet the changing needs and preferences of property owners.

The Dimensions of a Garage Door

Standard one-door and two-door garage door dimensions

Standard garage door dimensions, in most cases are:

  • Single door: 7ft (2,134 mm) x 7ft (2,134 mm)
  • Double door: 14ft (4,267 mm) x 7ft (2,134 mm) or 16ft (4,877 mm) x 7ft (2,134 mm)

A single garage door provides enough space for one vehicle, while a double door should be big enough to accommodate larger or multiple vehicles.

It isn’t always that straightforward though and often dimensions can be subject to several other factors including building regulations, the width of the space and the design of your garage door. You can also choose a bespoke garage door that is custom-made to suit the unique dimensions of your space. 

When Choosing a Garage Door

Choosing the right size for a garage door is crucial to ensure functionality, convenience, and a seamless fit with your property.

Here are several factors to consider when determining the size of a garage door:

Vehicle Dimensions

Consider the size of the vehicles you plan to store in the garage. Measure the width, height, and length of your vehicles to ensure that the garage door is wide and tall enough to accommodate them comfortably. Your vehicle dimensions may dictate your garage door dimensions. 

Number of Vehicles

If you have multiple vehicles or plan to use the garage for storage in addition to parking, factor in the number of vehicles you need to accommodate. A single-car garage door is typically smaller than a double-car garage door.

Garage Usage

Determine how you intend to use the garage. If you plan to use it for more than just vehicle storage, such as a workshop, storage space, or recreational area, you may need a larger door to accommodate various activities.

Architectural Style

Consider the architectural style of your home. The garage door should complement the overall design of the property. Some architectural styles may benefit from specific garage door designs or sizes to maintain aesthetic harmony.

Local Building Regulations

Check with local building regulations. Some areas have specific requirements regarding the size and dimensions of garage doors. Adhering to these requirements is essential to ensure compliance with local regulations.

Headroom and Side Room

Measure the available headroom and side room in your garage. Headroom refers to the space between the top of the garage door opening and the ceiling, while side room is the space on each side of the door. Different garage door styles require varying amounts of headroom and side room.

Type of Garage Door

The type of garage door you choose can impact the required size. Traditional up-and-over doors, sectional doors, and roller doors have different mechanisms that may affect the available space inside and outside the garage.

Consider Future Needs

Anticipate future needs when choosing the size of your garage door. If you plan to upgrade to a larger vehicle or use the garage for additional purposes, it’s advisable to select a door size that accommodates potential changes.


The size of the garage door can influence the overall cost. Larger doors typically cost more than smaller ones. Consider your budget and balance it with your size requirements to find a suitable option.

Professional Advice

Consult with a professional garage door installer or contractor. They can assess your specific needs, take accurate measurements, and provide guidance on the most appropriate size for your garage door. Seeking professional advice ensures that your choice aligns with safety regulations, local building codes, and the unique characteristics of your property.
