Standard residential garage door sizes are a crucial factor when choosing the right door for your home. The correct size ensures smooth operation, improves curb appeal, and guarantees proper insulation and security. Whether you’re building a new home, replacing an old garage door, or upgrading for better style and function, understanding standard sizing will save you time, money, and headaches.
In this detailed guide, we’ll explore the 7 most popular standard residential garage door sizes, their uses, and important considerations so you can make the best choice for your home.
1. Why Knowing Standard Residential Garage Door Sizes Matters
Selecting the wrong garage door size can lead to costly modifications, poor fit, and reduced performance. Standard residential garage door sizes are designed to match the majority of homes in the U.S., ensuring that homeowners can replace or upgrade doors without expensive structural changes.
Having the right measurements also allows you to shop more easily for pre-manufactured doors, saving you time and reducing custom manufacturing costs.
2. Standard Residential Garage Door Sizes for Single Cars
One of the most common standard residential garage door sizes is for single-car garages. The typical width is 8 to 9 feet with a height of 7 to 8 feet.
- 8’ x 7’ – Ideal for compact cars and small SUVs.
- 9’ x 7’ or 9’ x 8’ – Offers extra clearance for larger vehicles like full-size SUVs or trucks.
If you’re upgrading, make sure your measurements account for side room and headroom required for tracks and openers.
3. Standard Residential Garage Door Sizes for Double Cars
For households with two vehicles, 16’ x 7’ is the most common standard residential garage door size. This allows comfortable space for two cars side-by-side.
Other double-door variations include:
- 14’ x 7’ – For smaller double garages.
- 18’ x 7’ – For oversized double garages or larger vehicles.
When choosing a double door, ensure your garage’s structural opening can support the extra width without compromising stability.
4. Oversized Standard Residential Garage Door Sizes
If you own tall vehicles like RVs, boats, or lifted trucks, you may require oversized standard residential garage door sizes.
Popular oversized dimensions include:
- 10’ x 8’
- 12’ x 12’
While these aren’t as common in residential neighborhoods, many modern homes with workshops or RV storage include them. These doors may require special hardware and heavier-duty openers.
5. Factors That Affect Choosing the Right Standard Residential Garage Door Size
When deciding between the different standard residential garage door sizes, consider:
- Vehicle type and height – Measure your tallest vehicle, including roof racks.
- Storage space – Extra clearance may be needed for shelving or storage inside the garage.
- Future needs – If you plan to upgrade to a larger vehicle, size accordingly now.
- Aesthetics – Proportional balance with your home’s façade matters for curb appeal.
6. Measuring for Standard Residential Garage Door Sizes
Accurate measurement is key before purchasing or ordering a door. To measure correctly:
- Width – Measure the distance between the left and right sides of the finished opening.
- Height – Measure from the floor to the top of the finished opening.
- Headroom – Measure from the top of the opening to the ceiling.
- Backroom – Measure from the garage door opening to the back wall.
A professional installer can double-check your numbers to ensure the door fits perfectly.
