Choosing the right garage door size is one of the most important decisions when building a new garage, replacing an old door, or upgrading your home’s storage and parking space. A garage door that is too small can make parking difficult, increase the risk of vehicle damage, and limit future flexibility. On the other hand, selecting the right dimensions improves convenience, safety, curb appeal, and even property value.
Whether you own a compact car, a full-size pickup truck, an SUV, or an RV, understanding standard garage door sizes helps you make an informed decision. This guide covers everything from common residential dimensions to custom options, pricing considerations, and expert recommendations based on vehicle type.
Garage Door Sizes at a Glance
The table below summarizes the most common residential garage door dimensions.
| Garage Door Type | Common Widths | Common Heights |
|---|---|---|
| Single Garage Door | 8 ft, 9 ft, 10 ft | 7 ft, 8 ft |
| Double Garage Door | 12 ft, 14 ft, 16 ft, 18 ft, 20 ft | 7 ft, 8 ft |
| Triple Garage Configuration | Varies | 7 ft, 8 ft |
| RV Garage Door | 10 ft–14 ft | 12 ft–16 ft |
| Custom Garage Door | Custom | Custom |
Among residential properties, the most common garage door sizes are:
- 9′ x 7′ for a single-car garage
- 16′ x 7′ for a double-car garage
- 16′ x 8′ for larger vehicles and modern homes
Many newly built homes now feature 8-foot-tall garage doors because modern vehicles continue to grow in size.
Standard Single Garage Door Sizes
Single garage doors are designed to accommodate one vehicle and are commonly found in smaller homes, detached garages, and workshops.
Common Single-Car Garage Door Dimensions
Standard single garage door sizes include:
| Size | Best For |
|---|---|
| 8′ x 7′ | Compact cars |
| 8′ x 8′ | Compact SUVs |
| 9′ x 7′ | Sedans and small SUVs |
| 9′ x 8′ | SUVs and crossovers |
| 10′ x 8′ | Larger trucks and SUVs |
The 9′ x 7′ size remains one of the most popular choices because it offers a good balance between accessibility and construction costs.
What Vehicles Fit in a Single Garage Door?
A standard single garage door works well for:
- Sedans
- Hatchbacks
- Compact SUVs
- Crossovers
- Small pickup trucks
Modern vehicles are wider than many people realize. For example, several popular SUVs exceed 78 inches in width without mirrors. When mirrors are included, parking space becomes even more important.
Pros and Cons of Single Garage Doors
Advantages
- Lower purchase cost
- Less maintenance
- Better energy efficiency when opening
- Simpler installation
Disadvantages
- Limited flexibility
- Difficult parking for larger vehicles
- Less room for future upgrades
Standard Double Garage Door Sizes
Double garage doors are designed for two vehicles and are the most common option in suburban homes.
Common Double Garage Door Dimensions
Typical double garage door sizes include:
| Size | Typical Use |
|---|---|
| 12′ x 7′ | Compact two-car garages |
| 14′ x 7′ | Smaller double garages |
| 16′ x 7′ | Standard two-car garage |
| 16′ x 8′ | Larger vehicles |
| 18′ x 8′ | Luxury homes |
| 20′ x 8′ | Extra-wide garages |
Why 16′ x 7′ Is the Most Popular Double Garage Door Size
The 16-foot-wide garage door offers enough space for:
- Two average-sized vehicles
- Comfortable entry and exit
- Mirror clearance
- Additional maneuvering room
Builders often prefer this size because it balances practicality and affordability.
Vehicle Capacity and Clearance Considerations
When planning a double garage door, consider:
- Vehicle width including mirrors
- Driver and passenger door opening space
- Storage shelves
- Workbenches
- Bicycle storage
A garage may technically fit two vehicles, but comfortable daily use often requires additional clearance.
One Large Door vs Two Separate Doors
Many homeowners debate whether to install one double garage door or two single doors.
One Large Door
Benefits:
- Lower installation cost
- Modern appearance
- Easier access
Drawbacks:
- More heat loss when opened
- Larger replacement cost
Two Single Doors
Benefits:
- Better insulation performance
- Individual operation
- Traditional appearance
Drawbacks:
- Higher installation cost
- More hardware to maintain
Triple Garage Door Sizes and Layout Options
Triple garages are increasingly popular among families with multiple vehicles, recreational equipment, or workshop needs.
Common Triple Garage Configurations
Most triple garages use one of these layouts:
Three Single Garage Doors
This design places three separate doors across the front of the garage.
Benefits include:
- Independent operation
- Enhanced architectural appeal
- Better energy efficiency
One Single Door and One Double Door
A common configuration includes:
- One 9-foot single door
- One 16-foot double door
This setup provides flexibility while minimizing construction costs.
Is There a Standard Triple Garage Door Size?
Unlike single and double garage doors, there is no universal standard for one large triple-width door.
Most builders prefer multiple-door configurations because extremely wide doors:
- Require stronger hardware
- Cost more
- Place greater stress on tracks and springs
Custom Triple Garage Door Solutions
Custom garage door manufacturers can create oversized triple-width doors for modern homes, luxury garages, and specialty vehicle storage.
Recommended Garage Door Sizes by Vehicle Type
Not all vehicles require the same garage door dimensions.

This size provides sufficient width and comfortable clearance for most passenger vehicles.

Additional height helps accommodate roof racks and cargo carriers.

Plan for Future Vehicle Upgrades
One common mistake homeowners make is selecting a garage door that only fits their current vehicle.
If you anticipate purchasing:
- A larger SUV
- A truck
- A camper
- A recreational vehicle
Choosing a slightly larger door today can prevent expensive modifications later.
Garage Door Width Guide
Width affects more than just whether your vehicle fits through the opening.
How Much Width Do You Really Need?
A garage door should provide enough space for:
- Vehicle mirrors
- Driver visibility
- Safe maneuvering
- Passenger access
Recommended Side Clearance
Experts generally recommend leaving at least:
- 12 to 18 inches of clearance on each side of a parked vehicle
More space improves comfort and reduces accidental scratches.
Parking Comfort vs Minimum Requirements
A garage may technically fit your vehicle, but practical use often requires additional room.
For example:
- A compact sedan can fit through an 8-foot opening.
- A large SUV is significantly easier to park through a 9- or 10-foot opening.

Height is increasingly important as vehicles become taller.
Standard 7-Foot Garage Doors

They work well for:
- Sedans
- Compact SUVs
- Small crossovers
Benefits of 8-Foot Garage Doors
Advantages include:
- Easier parking
- Accommodation of roof racks
- Better future-proofing
- Increased resale appeal
When You Need a Taller Door
You may need a 10-foot, 12-foot, or taller garage door for:
- Lifted trucks
- Cargo vans
- RVs
- Boats on trailers
Roof Racks and Cargo Boxes Matter
Many drivers forget to account for:
- Kayak carriers
- Cargo boxes
- Bike racks
- Roof storage systems
These accessories can add significant height.
Garage Door Sizes for Attached vs Detached Garages
The type of garage affects sizing decisions.
Attached Garages
Attached garages often prioritize:

How to Measure Garage Door Size Correctly
Accurate measurements prevent costly mistakes.
Tools You Need

Garage door systems require adequate headroom for tracks and springs.
Measure Side Room

Backroom is the distance from the opening to the rear wall.
The garage door must have enough space to fully open.
Common Measuring Mistakes
Avoid:

- Forgetting headroom requirements
- Estimating dimensions
Garage Door Rough Opening Dimensions Explained

Builders typically size the rough opening to match the garage door dimensions.
Construction Considerations
When building a new garage, ensure adequate space for:
- Tracks
