Three-Car Garage Door

Three-car garages have a bit more flexibility by having one large door or a combination of smaller doors along the whole garage. A common size for a single three-car garage door is 24 feet wide by 7 feet high leaving space to comfortably fit your vehicles.

Alternatively, you might see configurations with two doors, one 16 feet wide by 7 feet high and another 8 feet wide by 7 feet high, or three individual doors, each 8 feet wide by 7 feet high.

These options allow for various combinations to fit your specific needs whether it’s a side of the garage for storage or simply fitting three different vehicles in your garage.

Custom Garage Doors

Now normally the garage doors we’ve already mentioned meet most homeowner’s needs, custom garage doors are available for those who have unique requirements or wishes. These custom doors can be tailored to fit unusual garage dimensions, oversized vehicles, or specific design preferences you have for your garage. When planning a custom garage door, make sure to consider the following:

RV/Oversized Garage Door

This is a bit more specific but for those who own recreational vehicles (RVs) or large trucks, the standard garage door might not be tall enough at only 8 feet or 9 feet. RV garage doors are typically 12 to 14 feet high and 10 to 12 feet wide which allow the larger height and width RVs park safely and conveniently.

What to Consider When Choosing a Garage Door

Now when selecting your garage door sizing or repairing/replacing your current garage door, there are a few things you should consider when doing so. 

Vehicle Size

The size of your vehicles is a primary factor in determining the garage door dimensions. Ensure that the door is wide and tall enough to accommodate your vehicles comfortably. It’s no fun to have a garage door that is hard to enter and exit. 

Garage Layout

Consider the layout of your garage when selecting a door size. If you have storage or other features inside the garage, make sure the door size allows for easy access and movement. Tight spaces make moving items around tough and getting in and out of your car a hassle. 

Future Needs

The classic but make sure you’re thinking about future purchases and needs. Whether that be a larger vehicle or the need for ample storage space, choosing a slightly larger garage door can help you save the hassle of replacing it later and just focus on garage door repairs if needed. 

Aesthetic Appeal

Now your garage door might not be the first thing you think of when home aesthetic but it certainly has an impact. It’s normally front and center which makes it one of the first eye catching pieces of your home. Make sure to choose a size and design that helps complement your home and enhance curb appeal.
