How Wide 2 Car Garage Door Should Be: Expert Sizing Guide
Thinking about installing a new garage door or replacing your old one? One of the first questions that comes up is: How wide is a 2 car garage door? Whether you’re building a new house, remodeling, or just want to park two cars comfortably, knowing the right garage door width is essential. The right size makes daily use easier, keeps your vehicles safe, and even affects your home’s curb appeal.
But choosing the correct width is not as simple as picking a number. There are standard sizes, but also custom options for special needs. Factors like the type of vehicles, available space, and even local weather can affect your choice.
Many people make mistakes by guessing the size or following old standards that no longer fit today’s cars. In this guide, you’ll find clear explanations, real examples, and tips that most people miss.
Let’s explore everything you need to know about the width of a 2 car garage door. By the end, you’ll be able to choose the right size with confidence.
What Is A 2 Car Garage Door?
A 2 car garage door is designed to allow two vehicles to enter and exit side by side. It usually means a single, wide door that opens to a space big enough for two cars. Some garages use two separate single doors, but this guide focuses on the single door style.
This type of door is common in family homes, suburban houses, and properties where space is important. It’s popular because it provides easy access, a modern look, and better security for two vehicles compared to separate single doors.
Standard Widths For 2 Car Garage Doors
The most common question is: What is the standard width for a 2 car garage door? In the United States, the answer is clear but not always simple.
Most 2 car garage doors are:
- 16 feet wide (192 inches)
- 18 feet wide (216 inches)
These widths fit most modern vehicles comfortably. Some older homes or custom garages may have doors as narrow as 14 feet (168 inches), but this is less common today.
Here’s a quick comparison:
| Width (feet) | Width (inches) | Typical Use | Pros | Cons |
|---|---|---|---|---|
| 14 | 168 | Older or small garages | Fits in tight spaces | Very narrow for two cars |
| 16 | 192 | Modern standard | Fits most cars, SUVs | May be tight for large trucks |
| 18 | 216 | Luxury or custom homes | More space, easier parking | Needs more wall space |
Key insight: The 16-foot width is the most popular and fits most needs, but larger vehicles or families with extra storage needs may prefer 18 feet.
Why Garage Door Width Matters
Choosing the right garage door width isn’t just about fitting two cars. It affects your daily life in many ways:
- Parking Comfort: A wider door means less risk of scratching car doors or mirrors when parking.
- Vehicle Types: If you drive large SUVs, trucks, or vans, a narrow door can make entry and exit difficult.
- Storage Needs: Many people store bikes, tools, or lawn equipment in the garage. More width means easier access.
- Home Value: A modern, properly sized door can make your home more attractive to buyers.
Many homeowners don’t realize how quickly a garage can feel cramped if the door is too small. It’s not just about the cars—it’s about everything you use the garage for.
Measuring For A 2 Car Garage Door
Before you buy or install a new door, you need to measure your garage opening correctly. Even a small mistake can lead to expensive problems.
Steps to measure:
- Width: Measure from the left to the right side of the garage opening at the widest point.
- Height: Measure from the floor to the top of the opening.
- Side Room: Check the space on each side of the opening. You need at least 3.5 to 5 inches on each side for the tracks.
- Headroom: Measure the space between the top of the opening and the ceiling or any obstructions. Standard doors need at least 12 inches.
- Backroom: Measure the depth from the opening to the back wall. You need enough space for the door to fully open.
Common mistake: Many people forget to check the side and headroom, leading to installation issues or the need for expensive modifications.
Factors That Affect Garage Door Width Choice
Not every home or family needs the same size door. When choosing how wide your 2 car garage door should be, consider:
Vehicle Size
Think about the cars you own and may own in the future. Compact cars fit almost anywhere, but large SUVs, pickup trucks, or vans need more room. Measure the width of your widest vehicle, add space for opening doors, and check if a 16-foot door is enough.
Number Of Vehicles
Some families have two small cars, while others might park a car and a motorcycle, or even use part of the garage for storage. If you need extra space for hobbies or equipment, consider going wider.
Garage Layout
Is your garage long and narrow, or does it have extra depth? Is there a step or storage shelf along one wall? These details can affect how much usable width you really have.
Local Building Codes
Some cities or neighborhoods have rules about garage door sizes. Check with your local building office before making a final decision.
Budget
Wider doors cost more—not just for the door itself, but also for installation and possible structural changes. Balance your needs with your budget, but don’t sacrifice daily convenience.
16-foot Vs 18-foot Garage Doors
The choice usually comes down to 16 feet or 18 feet. Each has advantages and disadvantages.
16-foot Garage Door
- Fits most homes and cars
- Usually less expensive
- Easier to install, especially in existing garages
- Can feel tight for two large vehicles
18-foot Garage Door
- More comfortable for large vehicles or extra space
- Better for families with kids or those who need to move items in and out often
- May require changes to garage framing
- Higher cost
Practical tip: If you’re unsure, mark the width on your garage wall with tape and try parking your vehicles side by side. See how it feels before making a final decision.
Custom Garage Door Widths
While 16 and 18 feet are standard, some situations call for a custom size. This is common in:
- Older homes with non-standard garages
- Luxury homes needing extra-wide doors (up to 20 feet)
- Garages with special requirements, like for RVs or boats
Custom doors can be made to almost any width, but costs rise quickly. Lead times are also longer, since these doors are built to order.
Non-obvious insight: If you need a custom width, ask about repair and replacement costs. Special sizes can be harder and more expensive to fix in the future.
Height Of 2 Car Garage Doors
While width is the focus, don’t ignore the garage door height. The standard height for 2 car garage doors is usually:
- 7 feet (84 inches)
- 8 feet (96 inches)
Most modern vehicles fit under a 7-foot door, but if you own a tall SUV, van, or truck with a roof rack, you may need 8 feet or more.
Here’s a quick height comparison:
| Height (feet) | Height (inches) | Vehicles Supported | Notes |
|---|---|---|---|
| 7 | 84 | Most cars, SUVs | Standard for most homes |
| 8 | 96 | Tall SUVs, trucks | Better for large vehicles |
Practical tip: Always measure the total height of your vehicle, including roof racks or antennas, before choosing the door height.
Single Vs Double Garage Doors
Some garages have two single doors instead of one wide door. There are pros and cons to each choice:
Single Wide Door (one 2 Car Door)
- Easier to drive in and out, especially with wide vehicles
- Cleaner, more modern look
- Only one opener system to maintain
- If the door breaks, both cars can be trapped inside
Two Single Doors (side By Side)
- If one door breaks, you can still use the other
- More energy efficient (smaller opening = less heat loss)
- Offers more flexibility in garage design
- More expensive to install and maintain (two openers)
Non-obvious insight: Single doors are often narrower (8-9 feet each), making it harder to park wide vehicles. If you have a choice, a single wide door is usually more convenient for modern families.
Impact Of Door Width On Garage Design
The width of your 2 car garage door affects more than just parking. It changes the way you use your garage and even how your home looks from the street.
Curb Appeal
A well-sized, attractive garage door can boost your home’s value. Too narrow, and the garage looks cramped. Too wide, and it can dominate the front of the house. Many designers recommend matching the door style and color to your home’s exterior for a balanced look.
Interior Space
Wider doors mean you need more wall space for tracks and hardware. This can limit shelves, cabinets, or storage along the sides of your garage.
Energy Efficiency
Large garage doors let out more heat in winter and let in more heat in summer. Insulated doors and good weatherstripping are important if you use the garage as a workspace.
Security
A wide, sturdy door with modern locks keeps your cars and belongings safer. Avoid old or flimsy doors that can be forced open easily.
Installation Considerations
Installing a 2 car garage door is not a simple DIY project. It’s heavy, complex, and requires precise measurements. Here’s what to expect:
- Professional installation is almost always recommended
- Door panels are large and heavy (especially 18-foot doors)
- Tracks, springs, and openers must be aligned perfectly
- Incorrect installation can cause safety problems or void warranties
Before installation, check:
- Your garage’s framing can support the door’s weight
- There’s enough clearance for the door to open fully
- Electrical outlets are available for the opener
Practical tip: Ask your installer about service and warranty options. Garage doors need regular maintenance for safe operation.
Cost Of 2 Car Garage Doors By Width
Prices vary by size, material, brand, and features. Here’s a general idea of what you might pay for standard steel doors (excluding installation):
| Door Width | Average Price Range | Installation Cost (Estimate) | Total Cost |
|---|---|---|---|
| 16 feet | $800 – $2,500 | $500 – $1,000 | $1,300 – $3,500 |
| 18 feet | $1,000 – $3,500 | $700 – $1,200 | $1,700 – $4,700 |
| Custom | $2,000 – $6,000+ | $1,000+ | $3,000 – $7,000+ |
Extra costs can include insulation, windows, custom colors, smart openers, or heavy-duty springs.
Non-obvious insight: The price difference between 16 and 18 feet can be small if you buy a basic model, but rises quickly for premium or custom designs.
Materials And Their Effect On Width
The material of your garage door can affect the maximum width you can install safely.
- Steel: Most common, strong, supports wide doors
- Aluminum: Lightweight, less strong for very wide doors
- Wood: Classic look, but heavy, may need extra support for wide doors
- Fiberglass/Vinyl: Good for insulation, but less common in wide sizes
If you want a very wide door (18 feet or more), choose materials and hardware rated for that span.
Garage Door Openers And Width
Not all garage door openers can handle very wide or heavy doors. For a standard 16-foot door, a 1/2 horsepower opener is usually enough. For 18 feet or more, or if the door is heavy, a 3/4 horsepower or higher opener is better.
Tip: Consider a belt-drive opener for quieter operation, especially if there are bedrooms above the garage.
Accessibility And Special Needs
If someone in your family uses a wheelchair, walker, or has mobility issues, a wider garage door makes life much easier. Wider doors also help if you often carry groceries, strollers, or sports equipment in and out.
Practical example: A family with a child who uses a wheelchair found that a 16-foot door was too tight for easy access, but an 18-foot door made daily routines much smoother.
Mistakes To Avoid When Choosing Door Width
Many homeowners make simple but costly mistakes when picking garage door width:
- Guessing instead of measuring: Always measure your space and vehicles.
- Ignoring future needs: Buy for the cars you might own in the next 10 years, not just today.
- Forgetting about storage: Leave space for bikes, tools, or shelves.
- Overlooking building codes: Some areas have minimum or maximum door sizes.
- Choosing price over function: Saving a few hundred dollars now can lead to years of frustration.
When To Choose A Custom Width
While standard sizes work for most homes, you might need a custom width if:
- Your garage was built before 1980 and has a non-standard opening
- You have extra-large vehicles (like a van, RV, or boat)
- You want to combine two single doors into one extra-wide door
Always work with an experienced garage door company for custom projects. They can help with design, permits, and installation.
Real-world Examples
Family With Two Suvs
A family with two large SUVs found that their 16-foot garage door was a tight fit. Car doors would bump into each other or the wall. They replaced it with an 18-foot door, and now parking is easy and stress-free.
Homeowner With Classic Cars
A car collector wanted to store two classic cars side by side without risk of scratches. He chose a custom 20-foot door, plus extra insulation to protect the cars. The extra cost was worth the peace of mind.
Older Home Renovation
A homeowner with a 1950s garage had an opening less than 15 feet wide. They chose a custom 15-foot door instead of widening the opening, saving money on construction.
How To Choose The Best Width For Your Home
Follow these steps for a smart decision:
- Measure your garage opening carefully.
- Check your current and future vehicle sizes.
- Think about how you use your garage (storage, hobbies, etc. ).
- Consider your budget for both door and installation.
- Check local codes and HOA rules.
- Talk to a professional installer for advice.
Choosing the right width is not just about numbers. It’s about making your daily life easier and your home more valuable.
Additional Tips For Garage Door Planning
- If you’re building a new garage, plan for at least a 16-foot door—even if you only have one car now.
- Insulated doors help with noise and temperature control.
- Windows add light but can affect privacy and security.
