Standard Garage Door Sizes (And Why They Work for Most Homes)
Deciding between a single garage door size vs. double garage doors depends on your vehicles and lifestyle. These are the go-to dimensions most homeowners install.
Single Car Garage Doors
Single car garage doors typically measure 8′ x 7′ or 9′ x 8′.
This size car garage door is perfect if you have a compact car or only one vehicle. The width gives you enough space to open doors comfortably, and you can still squeeze bikes or storage along the sides.
An 8-foot-wide single garage door fits most sedans and smaller SUVs. If you drive something wider or want a bit of breathing room, the 9-foot option gives you that extra room. Height usually sits at 7 feet high for standard dimensions, though 8 feet high works better if you want extra vertical space for tall vehicles or overhead storage.
Double Garage Doors
Double garage doors run 16′ x 7′ or 18′ x 8′.
These are best if you have multiple cars or larger vehicles. The extra width opens up more storage or workspace potential inside your garage.
A 16-foot-wide double car lets you park two cars side by side with minimal clearance. An 18-foot-wide option gives you ample space for larger vehicles like trucks or SUVs.
You’ll find these door sizes on most double garages in residential neighborhoods.
Two Single Doors vs. One Double Door
Double garages can use either setup; it just depends on your style and what functionality you need. For example, two single doors give you flexibility. If one vehicle is gone, you can open just one side. This setup also works when your garage layout has a center support beam.
One large door creates a cleaner look and maximizes door opening width. You get better access for moving furniture or equipment in and out.
When deciding between a single and double garage door, consider side room for garage door openers and how each door can increase curb appeal.
Custom Garage Door Sizes: When Standard Just Doesn’t Cut It
If you custom-built your home or have large equipment, common garage door sizes might not work. Plus, your home is a reflection of who you are. The right garage door should fit and look perfect. Here’s a look at creating a customized garage door.
Why Go Custom?
Custom garage door sizes solve specific problems. Maybe you need extra space for SUVs, RVs, workshops, or storage. You could be matching unique architectural features on your home or increasing its value. Custom doors can boost your home’s curb appeal by creating better visual proportions.
What Affects Custom Garage Door Sizes?
When figuring out the right garage door size, garage dimensions are your best bet. Depth, height, and side room all play a role. For example, a garage with high ceilings can accommodate taller doors, giving you clearance for lifted trucks or storage racks.
Your rough opening structure also sets the limits. The rough opening is the space in your frame where the door installs. It needs to be slightly larger than the actual door size to allow for tracks and hardware. Check your back wall clearance, too. You need room for the door to roll up completely.
Measuring for a Custom Garage Door
Precise measurements make or break a custom garage door project. Grab your tape measure, measure the door opening width at three points (top, middle, bottom), and note all three; our technician confirms the size before ordering. Do the same for height on both sides.
But measuring is only half the story. Sometimes there are uneven openings, insufficient clearance or structural concerns to look into before ordering. That’s why professional installation helps you avoid costly mistakes.
A garage door specialist catches issues like these. We’ve seen homeowners order custom doors based on rough estimates, only to find they don’t fit when delivery arrives. Then they’re stuck with a haggle over replacements with manufacturers, behind on renovations, and stuck with extra costs all because of the wrong garage door measurements.
Choosing the Right Garage Door Size for Your Space
When looking into custom or standard garage door sizes, think about your space and daily life.
Vehicles and Usage
If you have larger vehicles, you’ll need to go bigger. A single-car garage won’t comfortably fit a full-size pickup truck. Similarly, if you’ve got only one car but need storage space, factor that into your garage size planning.
Is this a garage gym, workshop, or hobby area? Different garage door sizes work better for different uses. For instance, a woodworking shop benefits from a wider door opening for moving materials, while a simple home gym works fine with standard garage door sizes.
Consider Future Needs
If you’re planning on getting a larger vehicle down the road, plan ahead; a new garage door typically lasts 15 to 30 years with proper maintenance. Choosing different garage door sizes now saves you from another replacement down the road.
A starter home or investment property can really benefit from a great garage door. An oversized door on a small home looks off-balance. Smaller doors on a large facade feel cramped, for example.
Don’t Forget Insulation and Materials
Insulated garage doors might need slightly different dimensions or framing. The insulation quality adds thickness to panels, affecting the clearance needs. Material weight can impact door size and opener strength, too.
Heavier doors need more extensive hardware and stronger openers. Steel doors weigh more than aluminum, while wood doors are the heaviest.
Measuring Like a Pro: What You Need to Know Before Ordering
Ready to shop? Don’t skip these garage door measurements must-dos. Getting accurate dimensions prevents ordering mistakes that cost time and money.
Here’s what you need to measure and understand before placing your order:
Garage Door Opening vs. Actual Door Size
- The rough opening is the framed space where your door is installed.Â
- Garage doors are ordered to match the finished opening; the tracks, springs and hardware need side room and headroom around it.
- Typically requires 3-4 inches of side room on each side.
- It needs about 12 inches of headroom above the door opening.
- Always confirm these specs before ordering.
For example, a 16-foot-wide opening takes a 16-foot-wide door, plus about 4 inches of side room on each side for the tracks.
Back Wall and Side Room Clearance
- Clearance needs depend on your door type and track system.
- Standard sectional doors need backroom of about the door height plus 18 inches (more with an opener) to open fully.
- Minimum clearances for smooth operation include side room for vertical tracks (usually 3.75-4 inches on each side).
- Low-profile tracks reduce headroom requirements if your garage has a low ceiling.
- High-lift or vertical-lift tracks need more space but work great in garages with extra vertical space.
When to Call In the Pros
If you have a complicated layout, sloped ceilings, or odd architecture, a garage door specialist knows how to properly account for everything. Our technicians measure, identify problems, and recommend solutions before you commit to purchasing a new garage door.
Unusual garage dimensions might have hidden surprises, like structural beams in odd places, insufficient clearance, or framing that’s not square. Catching these issues early saves you from ordering a door that won’t work.
What Style Door Fits Which Size?
Some styles work better in certain sizes. Here’s a look at common garage door styles.
Carriage Style Doors
Carriage-style doors are usually heavier. They also have plenty of good side and overhead space for swing clearance (the sectional mechanism underneath the decorative exterior). These doors add traditional charm and can really increase your property’s curb appeal. Just make sure your garage has enough space to accommodate the weight and movement requirements.
Sectional Doors
Sectional doors are the most common garage door type and are flexible. They work with most standard garage door sizes. They roll up in sections along tracks, making them compatible with nearly any garage layout. This style works for both single garage door and double garage door configurations.
Single-Panel Doors
Single-panel doors swing out, so they need clear space in front of your garage. If you park close to your garage or have a short driveway, this style won’t work well. They’re less common today, but look beautiful in specific architectural styles when you have the clearance.
Side-Hinged Doors
Side-hinged doors need multiple doors or a wide single garage door opening. They swing open like regular doors, making them a great fit if you use your garage door as a second front door. They’re great for wider openings where you want easy walk-in access without operating the full door.

Frequently Asked Questions
What size RV garage door do I need?
Most RV garage doors measure 10 to 14 feet wide by 12 to 16 feet high, depending on your vehicle’s height and roof attachments. If you have slide-outs or a taller RV, custom garage door sizes can give you enough clearance for smooth entry and exit.
Measure your RV at its tallest and widest points, then add at least 2 feet to both dimensions for comfortable clearance.
When should I consider a garage door replacement?
You might need a garage door replacement if your current door is damaged, lacks insulation, or doesn’t align with your garage’s rough opening. Upgrading from an old door to a modern style can improve safety, energy efficiency, and curb appeal. Visible wear, excessive noise, or difficulty opening are all signs it’s time for a new garage door.
What is the standard garage door width for a two-car garage?
A typical two-car garage uses a door that’s 16 to 18 feet wide and around 7 to 8 feet high. If your vehicles are larger or you want more side clearance, larger garage doors may be a better fit. The 18-foot option gives you comfortable room for trucks or SUVs parked side by side.
How do I compare different garage door sizes for my new garage?
When planning a new garage, review the garage door dimensions based on how many vehicles you plan to park and how much storage space you’ll need. Comparing various garage door sizes helps you pick the one that works best for your garage layout and lifestyle. Consider future needs, too. Will you upgrade to larger vehicles down the road? Plan ahead and avoid multiple updates.
Are single car doors better than a single large garage door?
Single car doors give you flexibility if one side needs access while the other stays closed. This can be more energy-efficient. However, a single garage door with wider dimensions is usually easier to open and gives homes a cleaner look. It all depends on your garage type and usage. For example, two single doors work better with center support beams, while one large door maximizes the door opening width.
