Meta Description: Wondering how wide a single garage door is? Our 2025 expert guide breaks down standard sizes, custom options, and tips for Texas homeowners.
Many homeowners underestimate the importance of proper sizing until they face clearance issues or functionality problems. Suppose you’re wondering how wide a single garage door is. In that case, the standard width typically ranges from 8 to 10 feet; however, several factors may influence the ideal dimensions for your specific needs. At Keller TX Garage Door, we’ve helped countless homeowners navigate these critical decisions to enhance the function and form of their homes.
Understanding the correct garage door width affects more than just whether your car fits inside. It influences your home’s curb appeal, impacts energy efficiency, determines the ease of daily use, and can limit or expand the versatility of your garage space. Before making any decisions about installation or replacement, it’s essential to understand the standard measurements and options available in today’s market.
How Wide Is a Single Garage Door?
When homeowners ask, “How wide is a single garage door?” They’re usually seeking a straightforward answer to what seems like a simple question. In reality, single garage doors come in several standard widths, each designed to accommodate different vehicle types and needs.
The standard width range for a single garage door typically falls between 8 and 10 feet, with 9 feet being the most common dimension in modern homes. Standard heights generally measure between 7 and 8 feet, with 7 feet being the most prevalent.
Here’s a breakdown of typical single garage door size options.
- 8 feet wide × 7 feet high – Suitable for compact cars and motorcycles
- 9 feet wide × 7 feet high – Most common size, accommodates standard sedans and smaller SUVs
- 10 feet wide × 7 feet high – Provides extra clearance for larger vehicles
- 8-10 feet wide × 8 feet high – Taller option for cars with roof accessories or lifted trucks
For homeowners needing a quick reference, this comparison of width options can be helpful.
| Door Width | Best For | Clearance | Installation Complexity |
| 8 feet | Compact cars, limited space | Minimal | Standard |
| 9 feet | Mid-sized vehicles, standard homes | Moderate | Standard |
| 10 feet | Larger vehicles, workspace needs | Generous | Standard |
| Custom | Specific vehicle or usage requirements | Tailored | Complex |
While these dimensions represent industry standards, it is essential to note that the actual measurement needs for your specific situation may vary based on several factors that we will explore in the next section.
What Factors Determine Garage Door Width?
Vehicle Type (Sedan vs SUV vs Truck)
The primary consideration when determining the width of your garage door is the type of vehicle you plan to own. A standard sedan requires less clearance than a full-sized SUV or pickup truck. While an 8-foot door might suffice for a compact car, trucks and larger SUVs often need at least 9 feet of width for comfortable clearance. For those with extended-cab trucks or vehicles equipped with towing mirrors, a 10-foot width may be necessary to avoid tight squeezes or potential damage.
Remember to account not only for the vehicle’s width but also for the space needed to open doors comfortably and move around the vehicle while parked.
Driveway Layout and Turning Radius
Your property’s layout plays a significant role in determining the ideal width for your garage door. A straight, head-on approach to the garage allows for a standard-width door to be installed. In contrast, properties with sharp turns or angled approaches benefit from a wider opening to accommodate the required turning radius.
Consider how cars enter your garage from the street or driveway. If drivers must navigate a curve or angle to approach the door, additional width provides a more forgiving target, reducing the likelihood of accidental impacts with the door frame.
Building Code Requirements in Texas
Texas building codes establish minimum requirements for residential garage door dimensions, which can vary slightly by municipality. Most local codes in the Keller area require single garage doors to be at least 8 feet wide, though 9 feet has become the de facto standard for new construction to accommodate today’s larger vehicles.
Beyond width requirements, Texas building codes also address structural support, wind resistance ratings (especially important in areas prone to severe weather), and safety features such as auto-reverse mechanisms. Always check with local building authorities before proceeding with a new installation or significant modification.
Builder/Architect Design Preferences
The architectural style of your home can influence the appropriate size of your garage door. Colonial and craftsman-style homes often feature proportionally sized garage doors that complement the overall aesthetic, while contemporary designs might incorporate oversized doors as a design statement.
Builders and architects consider not just functionality but also visual balance, ensuring the garage door doesn’t overwhelm the home’s façade. This is especially important for front-facing garages, which significantly impact curb appeal.
Are There Custom Sizes for Single Garage Doors?
While standard sizes meet the needs of most homeowners, custom garage door dimensions are ideal for specific situations. Custom widths, such as 9.5 feet or 10.5 feet, can provide the “just right” solution when standard options are too tight or unnecessarily large.
Custom sizing becomes necessary in several scenarios.
- Accommodating oversized vehicles like dual vehicles or cars with extended mirrors
- Converting existing structures into garages where standard framing isn’t present
- Creating multi-purpose spaces where vehicles share space with workshop areas
- Retrofitting historic homes where modern standard sizes don’t align with original construction
- Addressing unique architectural designs or unusual lot configurations
The advantages of custom sizing include perfect space utilization, improved aesthetic alignment with unique architectural styles, and optimal functionality for specific vehicle needs. However, these benefits come with considerations: custom doors typically cost 15-30% more than standard sizes, may have longer lead times for fabrication, and might require more extensive framing modifications during installation.

Common Mistakes When Measuring Garage Door Width
Measuring From the Wrong Points
The most frequent error homeowners make is measuring the existing door rather than the opening itself. Proper measurement requires identifying the finished opening width—the distance between the left and right sides of the jamb where the door will be installed. Measuring the current door panel alone doesn’t account for tracks, weather stripping, and clearance requirements.
For accurate measurements, use a tape measure to determine the width at three points: the top, middle, and bottom of the opening. The smallest of these three measurements should be considered your actual opening width.
Ignoring Header Clearance
While focusing on width, many homeowners overlook the equally important headroom clearance—the space between the top of the door opening and the ceiling or obstructions, such as beams or light fixtures. Insufficient header space can limit door options or require expensive structural modifications.
Standard new garage doors need at least 12 inches of headroom for proper track installation, while high-lift or specialized doors may require significantly more. Always measure both width and height clearances before selecting your door.
Not Factoring in Trim and Framing
Another common oversight is failing to account for finishing elements, such as trim, molding, or decorative accents, that may protrude into the opening. These elements can reduce the functional width by several inches on each side.
Similarly, many DIYers don’t consider the structural framing requirements. A 9-foot door requires an opening slightly larger than 9 feet to accommodate proper installation hardware and weather sealing.
Measuring Tips
- Always use a metal tape measure, not cloth or plastic, for accuracy
- Measure the width at three points and use the smallest measurement
- Verify the squareness of your opening by measuring diagonally in both directions
- Include notes about any obstructions like light switches, outlets, or pipes
- Take photos of your measurements and the opening for reference

FAQs About Single Garage Door Width
Can a truck fit through a standard 8-foot garage door?
Many standard-sized pickup trucks can fit through an 8-foot-wide garage door, but it can be a tight squeeze, especially with larger trucks or when extra room is needed for mirrors or maneuvering. To be sure, it’s wise to measure your truck’s width, including mirrors.
Is a 9-foot-wide garage door sufficient?
A 9-foot wide garage door offers significantly more clearance than an 8-foot door and is generally considered a good size for single vehicles. This extra foot of width can make it easier to drive in and out, especially for larger cars or less experienced drivers.
What size garage door do I need for my SUV?
An 8-foot-wide new garage door should be sufficient for most standard SUVs. However, a 9-foot-wide door is often recommended for larger SUVs or if you prefer more maneuvering room. Consider the width of your specific SUV, including the mirrors, when making your decision.
How do I know if I need a custom width?
You may need a custom-width garage door if you have oversized vehicles, such as large trucks or RVs, if your garage opening is non-standard, or if you require extra space for specific reasons. Measuring your vehicle and the garage opening will help determine if a custom size is necessary.
