Standard Garage Door Sizes: A Complete Guide
While installing or upgrading to a new garage door, one of the key things to consider is the size. Garage doors are available in various sizes. There is a range of standard sizes to fit different vehicles, storage requirements, and home designs.
Therefore, it is important to know the standard garage door sizes so that you can choose the right one without facing issues during installation.
In this post, we will understand the most common garage door dimensions, walking through the differences between single and double garage door sizes, and learn how to measure properly.
Why Garage Door Sizes Matter
A garage door is not just for your car. Rather, it is an entry point to your home. It enhances your curb appeal. A door should match your garage door opening size. Otherwise, you can encounter problems with installation, insulation, and routine use.
Choosing the right size ensures:
- Enough clearance for vehicles
- Smooth operation of the door
- Proper sealing against weather and pests
- Long-lasting performance with minimal repairs
Typical Garage Door Measurements
Although custom sizes are available, the manufacturers tend to make typical garage door measurements that will fit ‘most’ homes. These sizes are based on decades of construction standards and vehicle sizes.
Here are ranges for some of the most common sizes for residential garage doors:
- Width: 8 feet to 18 feet
- Height: 7 feet to 8 feet
Custom options are usually anything larger or smaller.
Single Garage Door Dimensions
This type is suitable for a single vehicle. It’s the most popular option for older houses and compact garages.
A standard single garage door has the following sizes:
- Width: 8 feet to 10 feet
- Height: 7 feet to 8 feet
- 8 feet x 7 feet – Found in older homes or for small cars
- 9 feet x 7 feet – Common size for today’s standard automobile and SUV
- 10feet x 7feet — Provides extra space for larger vehicles such as trucks.
If you have a big SUV or pickup, opt for a 9- or 10-foot wide door for more comfortable parking.
Double Garage Door Dimensions
The two-car garage has a double garage door. It accommodates two cars through a single large opening instead of the twin smaller ones.
Here is the standard double garage door size:
- Width: 16 feet to 18 feet
- Height: 7 feet to 8 feet
- 16 feet x 7 feet – The most common choice for two-car garages
- 18 feet x 8 feet – Offers extra width and height for oversized vehicles or storage space
Other homeowners may choose not to have a single double door but two total single doors. This allows a little more freedom of design and means that one side of the garage is usable even if the other side experiences a problem and needs repairing.
Garage Door Height and Width
Garage doors are typically 7 feet or 8 feet tall. Garage door heights and widths depend on the size of the garage, measurements for the overhead door, as well as your vehicle size and clearance availability.
- 7 feet tall: The most typical height, fits well for all cars except very large SUVs
- 8 Foot High: Typically for the taller vehicles, including trucks, or if you use roof racks.
For width, 8-10 feet works for single doors and 16-18 feet for double doors — wide enough to fit any SUV.
Average Garage Door Size
Generally speaking, in terms of average garage door size, what they mean is:
- Door 1: 9 feet 0 x 7 feet 0 Single Door
- Double Door: 16feet W X 7 feet H
This encompasses the majority of more contemporary homes (those built in the last 20 years).
Oversized and Custom Garage Doors
Home — not every home or vehicle is a standard size. Not all garages need large doors.
- Garage doors for RVs: typically 10–12 feet wide as well as 12–14 feet tall
- Commercial Garages: Over 20 feet wide, and over 14 feet high
- Custom designs: Could be created for specific architectural styles or unusual cars

Measuring a Garage Door
Make sure to have accurate garage door measurements in place before ordering. Here’s how you can take the measurement.
Width: Measure from side to side across the opening.
Height: Measure from the bottom of the opening to the top of the opening.
Headroom: From the ceiling above the opening.
Backroom: Take depth of garage (needed for tracks)
Sideroom: The measurement space for both sides of the opening
Tip: Consider multiple spots for measurements, as walls and floors are not exactly a perfect square.
Factors That Influence Garage Door Size
When choosing a door, consider:
- What kind of vehicle do you have? Do you have a truck, SUV, or small car?
- Are you looking to buy a larger car or RV?
- Garage Layout–Attached vs detached, ceiling height, storage.
- Aesthetics is also important. Do you like two single doors or one double door?
- Climate is also a major factor, as bigger doors might require more insulation.
Final Thoughts
By this point, you must be clear about your choices. Garage doors are a big investment. Therefore, it is important to ponder over all the factors before choosing them. Most homes use standard single garage door sizes or standard double garage door sizes for a simple process.
It all boils down to these key points.
