Standard Garage Door Sizes for Residential Homes

Standard Garage Door Sizes for Residential Homes

Residential homes typically have standard garage door sizes, including single car doors ranging from 8' x 7' to 9' x 8', double car doors ranging from 7' x 16' to 8' x 18', and triple car doors usually measuring around 7' x 20'.

Single car garage doors (8' x 7', 8' x 8', 9' x 7', or 9' x 8')

Single car garage doors come in several standard sizes. These include 8 feet by 7 feet, 8 feet by 8 feet, 9 feet by 7 feet, and finally the largest - being a full nine square feet.

Each size serves different space needs within your garage. The smallest one at eight by seven fits most compact cars with room to open both doors comfortably. For taller vehicles like trucks or SUVs, consider an eight-by-eight door.

It gives extra vertical clearance that prevents any accidental scrapes from occurring on your vehicle’s roof rack. Alternatively, homeowners with longer cars can opt for a nine-foot-wide version available in two heights: Seven or eight foot tall doors prevent you risking damage to the front or rear of lengthy vehicles while manoeuvring through tight spaces..

Double car garage doors (7' x 16', 7' x 18', 8' x 16', or 8' x 18')

Double car garage doors put a premium on space. They cover four standard sizes: 7' x 16', 7' x 18', 8' x 16', or 8' x 18'. Homeowners generally choose these larger door sizes when their garages need to accommodate two vehicles simultaneously.

It's also an excellent choice for those who own bigger, bulkier vehicles like SUVs, trucks, or vans.

A double garage door offers more than just car parking. The extra room can serve as storage space for bikes, tools and sports equipment without cramping the area needed for cars. Also, with these dimensions (from seven feet high and ranging from sixteen to eighteen feet wide), they bring added convenience allowing drivers to park without worrying about hitting the sides of the openings.

Despite its size, current models come equipped with automatic openers making it easy and convenient for homeowners.

Triple car garage doors (generally 7' x 20')

Triple car garage doors, usually measuring 7 feet tall by 20 feet wide, provide ample space for three vehicles side-by-side. This type of door is typically found in larger homes or properties with extensive garages.

These doors don't just offer room for more cars but also accommodate larger vehicles such as SUVs and trucks. It's crucial to ensure enough clearance on both sides of the garage opening when considering this size, as an extra-wide door may require additional structural support.

You also need sufficient driveway space to easily maneuver your cars into and out of the garage efficiently. Opting for a triple car garage door can significantly enhance your home's curb appeal while providing you with increased storage capabilities.

Carriage house-style garage doors

Carriage house-style garage doors add a touch of elegance and charm to any home. These doors are designed to resemble the traditional carriage houses from the past, with their rustic wood or faux-wood finishes and decorative hardware.

They often feature swing-out operation or fold-up technology, giving your garage a unique and eye-catching look. Carriage house-style doors can be customized to fit your specific garage dimensions, ensuring a perfect fit every time.

Whether you want to enhance the curb appeal of your home or create a statement piece for your garage, carriage house-style garage doors are an excellent choice.

Factors to Consider When Choosing a Garage Door Size

Factors to Consider When Choosing a Garage Door Size

When choosing a garage door size, factors such as the number and size of vehicles to be parked, available headroom and clearance for a garage door opener, and the layout and style of the garage should be considered.

Number and size of vehicles to be parked

Consider the number and size of vehicles you plan to park in your garage when choosing a garage door size. If you have one car, a single car garage door with dimensions like 8' x 7' or 9' x 8' would be suitable.

For two cars, opt for a double car garage door measuring around 7' x 16', 8' x 16', or similar sizes. Triple car garage doors are generally about 7' x 20'. Keep these factors in mind to ensure that your garage can accommodate your vehicles comfortably without any issues.

Available headroom and clearance for garage door opener

Ensure that you have enough headroom and clearance for your garage door opener. This is important to make sure that the opener can function properly without any obstacles in its way.

Measure the distance between the top of your garage door opening and the ceiling to ensure there is enough space for the opener to be installed. Additionally, check for any obstructions or objects like light fixtures or beams that could get in the way of the opener's movement.

Proper headroom and clearance are essential for smooth operation of your garage door opener.

Layout and style of garage

Consider the layout and style of your garage when choosing a new garage door. The size and shape of your garage can impact the type of door you need. For example, if you have limited space in front of your garage, a sectional door that opens vertically may be more suitable than one that swings open.

Additionally, consider the overall aesthetic of your home and choose a door style that complements it. Whether you have a modern or traditional design, there are various options available to match your garage's layout and style perfectly.

How to Measure for a New Garage Door

To measure for a new garage door, first determine the width and height needed for the opening. Consider the door thickness and consult with a professional for custom garage door sizes if necessary.

Determine the width and height needed

To determine the width and height needed for your new garage door, you will need to take accurate measurements of the opening. Measure the width between the side walls at several points, including near the floor and at mid-height.

Take note of the smallest measurement as this will be the width needed for your door. Next, measure the height from the floor to just beneath any obstructions such as ceiling beams or light fixtures.

Again, record the smallest measurement as this will be your required door height. Remember to account for any necessary clearances and consider leaving a little extra space for ease of use.

Consider the door thickness

The thickness of the garage door is an important factor to consider when choosing a new one. Thicker doors provide better insulation and can help with energy efficiency. They also tend to be more durable and resistant to damage.

On the other hand, thinner doors may be less expensive but may not offer the same level of insulation or durability. Make sure to take into account your specific needs and budget when deciding on the thickness of your garage door.

Consult with a professional for custom garage door sizes

For custom garage door sizes that go beyond the standard options, it is important to consult with a professional. They have the expertise and knowledge to help determine the right dimensions for your specific needs.

Whether you have unique requirements due to an existing structure or want something completely customized, a professional can guide you through the process and ensure that your new garage door fits perfectly.

Don't settle for off-the-shelf solutions when you can get a custom-sized door that meets all of your specifications.


Consider these standard garage door sizes for your residential home. Whether you have a single, double, or triple car garage, there are options available to suit your needs. Remember to factor in the number and size of vehicles, headroom, and clearance for openers, and the layout of your garage when choosing the right size. Measure carefully before purchasing or consult with a professional for custom sizes.
