If you are planning to build, renovate, or simply replace a garage door, understanding the right size is crucial. The garage door is not just an entry point; it impacts your home’s convenience, security, and even its curb appeal. Among various types, the double wide garage door is a popular choice for homes with two-car garages. But how wide is a double wide garage door, really? Is there a standard, or does it vary? Let’s explore every angle, from industry standards to customization options, and help you make the best decision for your home.
A double wide garage door is designed to cover the opening of a garage that can fit two vehicles side by side. This is different from having two single doors, where each door covers one car space. Instead, a double wide door offers a single, large opening. This makes it easier to drive in and out, especially if you have bigger vehicles or need extra space for storage and movement.
Most American homes with two-car garages use this style because it is practical, saves building costs, and often looks more modern. But while double wide doors are common, their exact width can vary depending on several factors, such as manufacturer, region, and custom needs.
The most common question is: How wide is a double wide garage door? Let’s look at the industry standards. In the United States, there are typical measurements that most manufacturers follow.
These sizes are measured in feet and inches, and they refer to the width of the door itself, not the frame or the opening.
While width is the main topic, height also matters. The standard height for double wide garage doors is usually:
Some custom homes may require different heights, but these are the most widely used.
To help you visualize, here is a simple comparison:
| Width (ft) | Width (in) | Common Use |
|---|---|---|
| 14 | 168 | Older homes, tight spaces |
| 15 | 180 | Small double garages |
| 16 | 192 | Standard two-car garages |
| 18 | 216 | Large garages, bigger vehicles |
As you can see, 16 feet is the most common. However, knowing the other sizes is helpful if your garage is not standard or you have special needs.

Choosing the right width is not just about fitting your cars. The width of the garage door affects:
One insight many beginners miss: The door width must match not only your cars but also your everyday habits. For example, if you carry bikes, lawn equipment, or have kids running in and out, extra width can make life easier.
Some people ask: Should I get two single doors or one double wide? Let’s compare the two options.
| Feature | Double Wide Door | Two Single Doors |
|---|---|---|
| Width | 14-18 feet | 8-9 feet each |
| Ease of access | Better for large vehicles | Can be tight for big cars |
| Cost | Usually cheaper to install | Higher, two doors needed |
| Appearance | Modern, clean look | Traditional style |
| Repair | One door may block both cars if broken | One door can still work if the other fails |
Most homeowners choose double wide doors for the convenience and modern appearance, but two single doors offer more flexibility if one breaks down.

Not every garage fits the standard. Some homes are older, have unique layouts, or owners want a special look. In these cases, garage doors can be custom-made.
Custom garage doors can be made in nearly any width, but most manufacturers recommend not going much wider than 20 feet for residential use. Beyond that, doors may become heavy, require stronger motors, and cost much more.
It’s wise to talk with a contractor or garage door specialist before ordering a custom width.
If you want to replace or install a new door, accurate measurement is key. Many beginners make mistakes here, leading to costly errors.
Always measure in several places. Garages can be uneven, so check the width at the top, middle, and bottom. If the measurements vary, use the smallest number. This prevents the door from getting stuck.
The width is just one factor. The style of your garage door impacts your home’s look and function. Let’s explore popular styles.
Sectional doors are the best choice for most homes due to their reliability and ease of use.
Many manufacturers offer insulated options, which help with energy efficiency and noise reduction.
A double wide garage door is heavier and larger than a single door, so it needs a strong opener.
Most standard double wide doors require at least a ½ horsepower motor. For doors wider than 16 feet or made of heavy materials (like wood), a ¾ horsepower or higher motor is recommended.
Modern openers include:
Some homeowners try to reuse a single door opener for a double wide door. This rarely works well and can wear out the motor quickly.
The price of a double wide garage door can vary based on width, material, style, and installation needs.
Installation costs depend on local labor rates and complexity. Wider doors may need extra supports or stronger openers, which can increase the price.
| Door Width (ft) | Material | Estimated Cost (Installed) |
|---|---|---|
| 16 | Steel | $1,200–$2,500 |
| 18 | Wood | $4,000–$6,000 |
| 16 | Insulated Aluminum | $2,000–$3,800 |
| Custom (20+) | Specialty | $5,000+ |
Installing a double wide garage door is more complex than a single door. Here’s what you need to think about:
If you live in a region with hurricanes or earthquakes, extra reinforcement may be needed. Check local building codes before buying.
A double wide garage door has more moving parts and weight, so regular maintenance is important.
Proper care extends the life of your door, prevents costly repairs, and ensures safe operation.
Many homeowners forget that wider doors can develop alignment issues faster than single doors. It’s smart to schedule professional inspections every couple of years.
Garage doors are a major entry point, so security matters.
Double wide doors especially benefit from these features because their size makes them more noticeable and potentially more vulnerable.

Garage doors can impact your home’s energy use. Wide doors let in more air, so insulation is important.
If your garage is attached to your home, investing in insulation is wise. It pays off in comfort and savings.
Deciding the best width for your garage door involves several factors:
If you are unsure, 16 feet is safe for most two-car garages. If you own larger vehicles or want extra space for storage, 18 feet may be better. Only choose custom sizes if you have unique needs and are ready for higher costs.
Let’s look at some real-life scenarios:
These examples show that the right width depends on your situation, not just a standard.
Most cities and states in the US have codes that affect garage door installation. For double wide doors, you may need:
Check with your local building department before ordering or installing a door.
Wide garage doors require more materials, energy, and resources. If you care about the environment:
Some manufacturers offer eco-friendly options. For more information, visit the U.S. Department of Energy.
A standard double wide garage door is 16 feet (192 inches) wide. This fits most two-car garages in the United States. Some homes may use doors that are 14, 15, or 18 feet wide, but 16 feet is the most common.
You can install a wider door, but your garage opening and framing must be expanded. This usually requires professional construction work and may involve moving walls or supports. Always check with a contractor before making changes.
Both options have pros and cons. Double wide doors are easier for large vehicles and usually cost less to install. Two single doors offer more flexibility if one fails and can match traditional home styles. Consider your needs, budget, and preferences.
The minimum width is usually 14 feet. This may be tight for modern cars, but works in older homes or where space is limited. For comfortable access, 16 feet is better.
Yes, wider and heavier garage doors require stronger openers (at least ½ horsepower, preferably ¾ for large or heavy doors) and sturdy tracks and supports. Using hardware designed for single doors is not safe or efficient.
The width of a double wide garage door plays a big role in your home’s function, safety, and value. While the standard is 16 feet, options range from 14 to 18 feet and can be customized for special needs. Choosing the right width depends on your garage size, vehicle type, and lifestyle. Remember to measure carefully, check local codes, and invest in quality materials and installation. With the right door, your garage will be more convenient, secure, and energy-efficient for years to come.
