How Wide Is a Single-Car Garage Door? A Size Guide
If you have ever stood in front of your garage and wondered whether your door is the right size, you are not alone. The right fit helps protect vehicle mirrors, improves daily convenience, and supports an efficient garage setup.
This guide explains common dimensions for single- and double-car doors, why size matters, and how to measure the opening before selecting a new door.
What Is the Standard Width of a Single-Car Garage Door?
A single-car garage door is commonly 8 or 9 feet wide, with many standard residential options measuring 7 feet high. An 8-by-7-foot door may work well for compact cars or sedans, while a 9-foot-wide opening offers more clearance for many larger vehicles.
The best width for your home depends on your existing opening, the type of vehicle you drive, and the amount of maneuvering space you need. Drivers of SUVs or trucks may prefer extra clearance when the garage layout allows it.
Common Single-Car Garage Door Sizes
Single-car doors commonly range from 8 to 10 feet wide and are often 7 or 8 feet high. Typical options include:
- 8 feet wide by 7 feet high: A classic size for compact cars and sedans.
- 9 feet wide by 7 feet high: A roomier option for full-size cars and many smaller SUVs.
- 10 feet wide by 7 feet high: A wider option for bays that need extra side clearance.
- 9 feet wide by 8 feet high: A useful option for taller vehicles or vehicles with roof racks.
Before choosing a size, measure your opening carefully and consider the vehicle you plan to park inside.
Standard Double Garage Door Sizes
For two-car garages with one wide opening, a common double-door size is 16 feet wide by 7 feet high. A 16-foot-wide by 8-foot-high option is also available for garages that need more height.
Some garages use two separate single-car doors instead of one large opening. Larger bays or special-use spaces may require wider or custom-sized doors.
Single and Double Garage Doors: What Is the Difference?
A single door serves one parking bay and takes up less wall space. A double door opens across a larger bay so two vehicles can park side by side. Each option has different framing, layout, and installation considerations.
When building a new garage or replacing an existing door, identifying the appropriate configuration before shopping can help you avoid costly adjustments later.
Why Garage Door Size Matters
Selecting the right size is not only about fitting your vehicle inside. It can also affect ease of parking, airflow, appearance, and everyday convenience.
- Vehicle clearance: An 8-foot door may be sufficient for a compact car, while an SUV or truck may need more space around the mirrors.
- Energy efficiency: A properly fitted door can help reduce unwanted airflow in an attached garage or workshop.
- Parking ease: A wider opening can make entering and exiting the garage more comfortable.
- Resale appeal: A garage that comfortably accommodates modern vehicles may appeal to future buyers.
How to Measure Your Garage Door Opening
Before ordering a new door or scheduling installation, measure the finished opening carefully.
Use a tape measure and record the following:
- Measure the width of the opening from one side of the framing to the other.
- Measure the height from the floor to the top of the opening.
- Check the available headroom above the opening for tracks and opener hardware.
- Note any obstructions, such as windows, framing supports, or roofline features.
When your measurements do not align with common sizes, a professional can determine whether a custom option is needed.
When to Consider a Custom Garage Door Size
Older homes, workshop bays, recreational vehicle storage areas, and unusually framed garages may not match standard dimensions. A custom-sized door can be made for the opening while allowing you to choose suitable materials, such as steel, wood, or insulated panels.
Custom sizing can also be helpful when a larger truck, specialized storage need, or unique parking layout requires more clearance than a standard option provides.
Using a Garage Door Size Chart
A size chart can help you compare available widths and heights from a supplier or manufacturer. Match the dimensions to your measured opening, then confirm clearance requirements for tracks and opener hardware.
For added confidence, a trained technician can verify your measurements and recommend an option that fits your opening, vehicle, and budget.
Conclusion
A single-car garage door is commonly 8 or 9 feet wide, while many double doors are about 16 feet wide. Before choosing a door, measure your opening and consider vehicle clearance and available headroom.
