When it comes to updating or replacing a garage door, the question always comes up: what is the average garage door size? It’s a practical detail that matters when you’re planning renovations or buying a new home. Whether you’re looking to fit a single car, a pair of SUVs, or need extra space for storage, understanding common garage door sizes can make the process less stressful and help you avoid costly mistakes.
While garage door sizes aren’t one-size-fits-all, there are standard options that fit most residential needs. These guidelines have made shopping for a new door simpler, but it’s still worth knowing what’s typical and what might work best for your home. Throughout this guide, we’ll look at the most common garage door sizes, what “standard” really means, and how to measure for the right fit.
When people talk about “standard” garage door sizes, they’re referring to the dimensions that fit most homes and vehicles across the country. These measurements aren’t random—they’ve been shaped by decades of building trends, vehicle sizes, and homeowner needs. Choosing a door that matches these standards often makes installation easier. Still, there’s flexibility, and understanding the full range of options can help you find the best fit.
Standard Single Garage Door Size
Most single-car garages use sizes that have proven to be the most practical over time. The two most common sizes you’ll see are 8 feet wide by 7 feet high and 9 feet wide by 7 feet high. These standard garage door sizes are designed to comfortably fit a single passenger vehicle, with some room to spare for storage or opening car doors. In newer homes, the 9-foot width is popular because it gives just a bit more clearance, which makes parking and unloading easier.
Standard Double Garage Door Size
If you have a two-car garage, you’ll often be looking at a standard double garage door size. The classic measurement here is 16 feet wide by 7 feet high. This size is spacious enough for two vehicles to park side by side without feeling squeezed, and it’s become the go-to choice for many suburban homes. You’ll also find some homes with slightly wider or taller doors, but 16 by 7 feet is the baseline for double doors in residential garages.
Common Garage Door Heights and Widths
While 7 feet is the standard height for most residential garage doors, 8-foot-tall doors are also widely available. The extra height can be a smart choice if you drive a larger SUV, truck, or even if you want to store items like roof racks or bikes on top of your car. If you have a camper or oversized vehicle, taller doors—sometimes 9 or even 10 feet high—are an option, though these are less common and often require special ordering.
Width can vary, too. Single doors can range from 8 to 10 feet wide, while double doors typically run from 12 to 18 feet wide. The key is to match the size of a garage door to your actual needs, factoring in the vehicles you drive now and what you might own in the future.
Not every garage is built to standard specifications. Older homes, unique architectural designs, or special vehicle storage needs sometimes call for something different. Whether you need an extra-wide door for a workshop, a taller opening for an RV, or a non-standard size to fit an unusual opening, customization options are available.
Double Garage Door Size
The standard double garage door size is 16 feet wide by 7 feet high. This dimension gives you enough room to park two cars side by side, open the doors comfortably, and still have a bit of breathing room for bikes or lawn equipment.
Of course, not every garage is built the same. Some homeowners opt for wider double doors—up to 18 feet wide. Height can also be adjusted. While 7 feet is the default, 8-foot-tall doors are increasingly common. Taller doors (9 feet or more) are available for those with lifted vehicles, roof racks, or who just want extra clearance for storage shelves or sports gear hanging from the ceiling.
What Size Cars Fit in a Double Garage Door?
A standard double garage door size—16 feet wide by 7 feet high—comfortably fits two average sedans, crossovers, or smaller SUVs. If you have a pair of full-size trucks or larger SUVs, the 16-foot width still works, but parking may require a touch more precision.
If you’re parking just one car but want lots of space for storage, a double door can also make sense. Ultimately, the right fit depends on your vehicles, your storage needs, and the way you use your garage day to day.
While most homes stick to standard garage door sizes, there are plenty of situations where something a bit different is needed. Maybe you’ve got a boat or a workbench that takes up extra space. Maybe your garage is part of a historic property, or you’re working with a unique architectural design. In these cases, less common garage door sizes (or even a fully custom door) can be the perfect solution.
When Are Less Common Sizes Needed?
It’s not unusual to see doors that are 10, 12, or even 14 feet tall if you’ve got an RV or oversized vehicles. Garages with high ceilings, or homes that use their garage for entertaining space, may use extra-wide doors—sometimes up to 20 feet. These sizes go well beyond the typical residential options, but they’re available through special order and are becoming more popular as homeowners look for flexibility.
Custom-Sized Garage Doors
If your opening doesn’t match the standard measurements, custom garage doors are an option. Clopay® offers a range of custom sizes for residential projects, whether you need a door that’s a few inches taller, extra-wide, or built to fit an unusual shape.
Custom doors are also a great way to match the look and proportions of your home’s architecture. If you’re restoring an older house or building something one-of-a-kind, a custom garage door can help everything look seamless.
Benefits and Drawbacks of Custom Garage Doors
There are a few things to keep in mind with custom garage doors. On the plus side, you get a door that fits perfectly, works for your vehicles and storage needs, and matches your home’s style. On the downside, custom doors typically cost more than standard options, and you may need to wait a bit longer for manufacturing and delivery.
Getting accurate measurements is necessary for a custom garage door, taking note of any irregular features—like angled ceilings or unusual framing—that could affect the fit. It’s always a good idea to consult with a Clopay® dealer or installer for help with measurements and to discuss your options. That way, you can be confident your custom door will fit and operate exactly as it should.
Before settling on a size for a garage door, it helps to think through your current needs and what might change in the future. Try to keep in mind and plan for:
Your Vehicle Size: If you drive a compact car, a standard single garage door size will likely do the trick. But if you own a full-size truck, SUV, or plan to upgrade to a larger vehicle down the line, it’s smart to consider a wider or taller door. Extra clearance means less stress when parking and reduces the risk of accidental scrapes or dings.
Storage Space: If you need extra storage, a larger door can make a real difference. It’s easier to move bulky items in and out, and you can use every inch of available space without worrying about squeezing through a narrow opening.
Local Building Codes: Before making any decisions, check your local building codes and homeowners’ association guidelines. Some areas have specific requirements for garage door sizes, particularly in historic neighborhoods or in flood zones.
Resale Value: Buyers look for homes with garages that will accommodate their vehicles and provide ample storage. A garage that feels cramped or can’t fit today’s larger cars may be a drawback for some. On the other hand, a generously sized garage door signals versatility and convenience. Choosing a more spacious, double garage door size can be a smart investment that appeals to a broader range of buyers.
