what is a standard 2 car garage door size

Ever struggled to fit your SUV through your garage door? You're not alone. Many homeowners face this frustrating challenge daily.

Choosing the correct standard 2 car garage door size is crucial for your home's functionality. The wrong dimensions can limit vehicle access and damage your property's curb appeal.

In this post, you'll learn the exact measurements for standard two-car garage doors. We'll cover width, height, and clearance requirements for comfortable everyday use.

Understanding Standard 2 Car Garage Door Dimensions

The Most Common Standard 2 Car Garage Door Size

When shopping for a two-car garage door, you'll encounter several standard sizes. The most common dimension is 16 feet wide by 7 feet high. This industry standard has served homeowners well for decades.

Newer homes often feature 16 feet wide by 8 feet high doors. This extra foot of height accommodates today's larger vehicles. SUVs, trucks, and vans benefit from this additional clearance.

For homeowners needing extra space, 18 feet wide variations are available. These wider doors provide more comfortable entry and exit for two vehicles. They're especially helpful if you own larger cars.

Regional differences exist across the United States. In some areas like Florida, taller garage doors (up to 10 feet) are more common. Western states often favor wider doors for bigger vehicles.

Here's a quick reference for standard two-car garage door dimensions:

Why These Dimensions Matter

The relationship between vehicle size and door width is crucial. Most cars measure between 5.2 to 6.5 feet wide. A 16-foot door leaves about 3-5 feet of clearance when two cars are parked.

Comfortable parking requires adequate space to open doors on both sides. We recommend at least 24 inches between vehicles. This prevents door dings and makes entering easier.

The standard dimensions have evolved significantly over time. In the 1950s, car widths averaged 5.5 feet. Today's SUVs and trucks can exceed 6.5 feet wide.

Modern garages now accommodate more than just vehicles. Many homeowners use garage space for:

· Storage

· Workshops

· Home gyms

· Laundry areas

This multi-purpose use has pushed manufacturers to offer larger standard sizes. Your garage door's dimensions directly impact how you use this valuable space.

Consider your specific needs when selecting a door size. The right dimensions make daily life more convenient and protect your investment.

Measuring for a 2 Car Garage Door: The Complete Process

Getting accurate measurements is crucial before ordering your standard 2 car garage door. Incorrect dimensions can lead to costly mistakes. Let's walk through the essential measurements you need to take.

Four Essential Measurements to Take

1. Rough Opening Width and Height

The rough opening is where your new garage door will be installed. Measure the width from side to side at the widest point. Standard two-car garage doors typically need 16 feet of width.

For height, measure from the floor to the top of the opening. Take this measurement in three places: the center and both sides. Always use the smallest measurement to ensure proper fit.

Pro tip: Add an extra inch on each side for insulation and safety. This extra space prevents the door from binding.

2. Side Room Requirements

Side room refers to the space on either side of your garage door opening. Most vertical track systems need at least 3.75 inches of clearance on each side.

Some track systems require up to 5.5 inches per side. This space houses the torsion springs and other hardware components.

Without adequate side room, your door won't operate properly. Make sure to check manufacturer specifications for your specific door model.

3. Headroom Considerations

Headroom is the space between the top of the door opening and your garage ceiling. Standard systems need 10-12 inches of headroom.

If you're installing an automatic opener, add an additional 3 inches. This means you'll need 13-15 inches total for most standard 2 car garage doors.

Insufficient headroom can prevent proper installation. Some low-headroom track systems are available if space is limited.

4. Backroom Measurement

Backroom refers to the depth of your garage from the door opening to the back wall. For a standard 2 car garage door, you need space equal to the door height plus 18 inches.

For example, a 7-foot tall door requires at least 8.5 feet of backroom depth. This allows the door to fully open without obstruction.

Common Measurement Mistakes to Avoid

Forgetting to Account for Trim and Framing

Many homeowners measure only the visible opening. They forget to account for trim and framing materials. This mistake can result in a door that's too large.

Remember: Measure the actual opening where the door will fit, not just the visible space. Standard trim materials are typically 3/4 inch thick.

Not Measuring at Multiple Points

Garage openings aren't always perfectly square or level. Taking just one measurement can lead to problems.

Always measure the height in three places: left side, center, and right side. For width, measure at both the top and bottom of the opening.

Use the smallest measurements to ensure your standard 2 car garage door will fit properly. This simple step prevents headaches during installation.

Overlooking Garage Door Opener Space Requirements

Your garage door opener needs adequate ceiling clearance. Many homeowners forget to factor this into their measurements.

Standard openers require about 3 inches of additional headroom. Track-mounted openers need space for both the door and opener mechanism.

Double-check that your ceiling can accommodate both components. This is especially important with standard 2 car garage doors, which are heavier than single doors.

Taking accurate measurements is the most critical step when ordering a new garage door. A measuring mistake of just an inch can cause significant installation problems. When in doubt, consult with a professional garage door specialist.

Two Single Doors vs. One Double Door for a 2 Car Garage

When designing your two-car garage, you face an important decision. Should you install one standard 16-foot double garage door or two separate 8-foot single doors? Each option offers unique advantages and potential drawbacks.

Pros and Cons of a Standard Double Garage Door (16'×7')

Visual Impact and Curb Appeal

A standard double garage door creates a clean, uninterrupted look. It provides a single visual element rather than two separate doors. This unified appearance often complements modern home designs.

Many homeowners prefer the streamlined aesthetic. However, a larger door can be visually dominant on your home's façade. This prominence might not suit every architectural style.

Convenience of a Single Opener System

With one standard 2 car garage door, you only need one opener system. This simplifies both installation and maintenance over time. You'll have one motor, one remote, and one set of safety sensors to manage.

The convenience extends to daily use as well. One button press opens access to your entire garage space. No need to decide which door to open when arriving home.

Cost Comparisons for Purchase and Installation

Let's break down the costs:

While the doors themselves cost about the same, the opener savings make a double door slightly more economical. You save both on initial purchase and future maintenance costs.

Energy Efficiency Concerns

Larger doors can affect your garage's temperature. When you open a 16-foot door, more air exchanges with the outside. This might impact energy efficiency, especially in extreme climates.

During winter, cold air rushes in faster. Summer heat enters more quickly too. If your garage connects to your home, this could affect your overall energy bills.

Benefits of Two Single Doors

Structural Advantages with Center Support Column

Two single doors require a center post between them. This column provides crucial structural support for your garage. It helps bear the weight of the header and roof above.

The center support makes the overall structure stronger. Many builders prefer this design for long-term durability. It can be especially important in areas with heavy snow loads.

Practical Benefits If One Door Malfunctions

Here's a scenario worth considering: What happens when a garage door breaks? With two separate doors, you still have access to half your garage.

If your only double door malfunctions, both vehicles might be trapped inside. Having two independent systems provides valuable backup access. This redundancy can be a lifesaver during emergencies.

Aesthetic Considerations for Different Home Styles

Two single doors often complement traditional architectural styles. They evoke carriage houses and historic designs. Many colonial, craftsman, and farmhouse-style homes look best with paired doors.

The center post creates visual separation that breaks up the garage façade. This can make the garage appear less dominant on your home's exterior. For larger homes, this balanced look often works better.

Parking Flexibility for Different Sized Vehicles

With two separate doors, you gain flexibility in how you use your garage space. Each bay can accommodate different vehicle sizes or purposes.

You might park your car in one bay while using the other for:

- A workshop area

- Storage space

- A home gym

- Lawn equipment

This divided approach makes it easier to organize your garage. You can open just one door when you only need access to half the space.

The choice between one standard 2 car garage door or two single doors depends on your specific needs. Consider your home's style, your practical requirements, and your budget when making this decision. Both options provide adequate space for two vehicles when properly sized.

Beyond the Standard: Custom 2 Car Garage Door Sizes

While standard 2 car garage door sizes work for most homes, they don't fit every situation. Sometimes, you need something bigger or differently proportioned. Let's explore when and why you might need custom dimensions.

When to Consider Non-Standard Dimensions

Accommodating Larger SUVs and Trucks

Today's vehicles are getting bigger. Many modern SUVs and trucks struggle with standard 7-foot height clearances. They might fit, but with very little room to spare.

If you own a full-size truck or large SUV, consider a taller door. Even a few extra inches can make a huge difference. You'll appreciate the extra space when loading roof cargo or bike racks.

Some telltale signs you need a larger door:

· Your vehicle's antenna scrapes the top

· You need to fold in mirrors to enter

· You hold your breath every time you pull in

· Your roof rack won't clear the opening

Options for RVs and Specialty Vehicles (10+ foot heights)

Standard two-car garage doors won't accommodate recreational vehicles. RVs need significantly more height clearance than regular vehicles.

If you own an RV, you'll need a specialized garage door. These typically range from 10 to 14 feet in height. They also require wider openings, usually 12 to 14 feet wide.

Many custom home builders now offer RV garages with these oversized doors. They provide shelter for your investment and easy access when preparing for trips.

Solutions for Older Homes with Non-Standard Openings

Many older homes have oddly sized garage openings. They were built when cars were smaller and before standardization became common.

Rather than rebuilding your entire garage, consider a custom-sized door. Manufacturers can create doors that perfectly fit unusual openings. This preserves your home's character while improving functionality.

Custom doors might cost more initially. However, they save you from extensive reconstruction expenses.

Popular Custom Sizes for Two-Car Garages

18×8 Feet Dimensions for Modern Vehicles

The 18×8 feet garage door has become increasingly popular. It offers two additional feet of width compared to standard doors.

This extra space provides several benefits:

· More room to open car doors without bumping walls

· Easier entry and exit for wider vehicles

· Additional peripheral vision when backing out

· Less stress when parking multiple vehicles

Many new construction homes now feature these larger openings. They accommodate today's bigger vehicles while providing extra breathing room.

20×8 Feet for Maximum Clearance

For the ultimate in spaciousness, some homeowners opt for 20×8 feet doors. These extra-wide openings provide maximum clearance for any vehicle combination.

They're particularly useful if you:

· Own multiple large vehicles

· Need space for a car plus workshop area

· Have mobility issues requiring extra door clearance

· Want flexibility for future vehicle purchases

While less common, these oversized doors create a luxurious garage experience. They eliminate the tight squeezes associated with standard-sized openings.

Height Variations for Taller Vehicles and Roof Racks

Height customization is becoming increasingly important. Many homeowners are choosing 8-foot tall doors instead of the standard 7-foot option.

The extra height allows for:

· Roof-mounted cargo carriers

· Bike racks and kayak mounts

· Lifted trucks and SUVs

· Future flexibility as vehicles continue to grow in size

Remember that customizing your garage door dimensions may require structural modifications. Always consult with a professional before making significant changes to your garage opening. The right size door enhances your home's functionality and your daily convenience.

Garage Door Thickness and Materials for 2 Car Garages

When selecting a standard 2 car garage door, thickness and material choices significantly impact durability, insulation, and appearance. These factors affect both performance and price.

Standard Thickness Options

The thickness of your garage door determines its insulation value and durability. Your climate and how you use your garage should guide this decision.

Non-insulated doors (approximately 1/8 inch thick) 

These basic doors consist of a single layer of steel or aluminum. They're the most affordable option but offer minimal temperature control. They work well in mild climates or detached garages where insulation isn't critical.

Basic insulated doors (1/4 to 1/2 inch foam insulation) 

These mid-range options add a layer of foam insulation to the interior of steel panels. They provide moderate temperature regulation and sound dampening. The insulation helps maintain a more consistent garage temperature year-round.

Well-insulated options (1 to 1.5 inches of insulation) 

Premium doors feature a sandwich construction with foam between two panels. They offer maximum energy efficiency and noise reduction. If your garage shares walls with living spaces or you use it as a workshop, this thickness is ideal.

Material Considerations for Standard Two-Car Garage Doors

Your door material affects appearance, maintenance needs, and lifespan. We've outlined the four most popular options below.

Steel doors: durability and maintenance 

Steel remains the most popular choice for standard 2 car garage doors. These doors resist dents and dings while requiring minimal upkeep. They come in various price points and insulation levels. Many homeowners choose steel for its strength and low maintenance requirements.

Key benefits include:

· Weather-resistant

· Available in numerous styles and colors

· Can mimic the look of wood at lower cost

· Relatively lightweight for opener systems

Wood doors: aesthetics and customization 

Nothing matches the warmth and character of wooden garage doors. They offer unparalleled customization options and classic beauty. However, they require regular maintenance to prevent warping, rotting, or fading.

Wood doors work beautifully with:

· Craftsman-style homes

· Tudor designs

· Rustic or farmhouse aesthetics

· Carriage house themes

Aluminum and glass: contemporary options 

For modern homes, aluminum frames with glass panels create a stunning visual impact. These doors let natural light into your garage while maintaining a sleek appearance. They're resistant to rust but can dent more easily than steel.

Modern designs often feature:

· Full-view glass panels

· Frosted privacy options

· Anodized aluminum frames

· Industrial-inspired looks

Fiberglass: lightweight alternatives 

Fiberglass doors offer excellent resistance to humid conditions. They can mimic wood grain without the maintenance concerns. Their lightweight nature makes them easier on garage door openers. They generally cost more than steel but less than real wood.

Installation Considerations for Standard 2 Car Garage Doors

Installing a standard 2 car garage door requires careful planning. The success of your installation depends on proper measurements and structural preparation.

Space Requirements

Headroom needed for different lifting mechanisms 

Standard track systems require 10-12 inches of headroom above the garage door opening. This space accommodates the horizontal tracks and torsion springs. Low-headroom alternatives exist but may affect performance.

If you're installing an automatic opener, add 3 more inches to your headroom requirements. These measurements ensure smooth operation without binding or jamming.

Side clearance for tracks and hardware 

Most standard 2 car garage door systems need at least 3.75 inches of space on each side. This room allows for proper track installation and operation. Some systems require up to 5.5 inches per side.

Without adequate side clearance, your door may:

· Stick during operation

· Fail to seal properly

· Cause premature wear on components

· Create safety hazards

Depth requirements for opened door position 

Your garage must be deep enough to accommodate the open door. For standard 2 car garage doors, you need a distance equal to the door height plus 18 inches. A 7-foot door requires about 8.5 feet of backroom depth.

Structural Concerns

Header support for 16-foot and wider openings 

The header above your garage door opening bears significant weight. For standard 16-foot openings, proper support is crucial. Wider doors place even more stress on this structural element.

Most builders use:

· LVL (laminated veneer lumber) beams

· Steel reinforced headers

· Multiple 2×12 boards laminated together

Always consult a structural engineer when installing doors wider than 16 feet. They can ensure your header can handle the load.

Center post removal considerations 

If you're upgrading from two single doors to one standard 2 car garage door, you'll need to remove the center post. This isn't a DIY project! The post likely provides crucial structural support.

Before removal, you must:

· Install a properly sized header beam

· Add temporary support during construction

· Ensure the new beam meets local building codes

· Consider wind load requirements for your area

Reinforcement needs for wider door installations 

Doors wider than 16 feet often need additional reinforcement. Horizontal struts prevent bowing and provide stability. For premium insulated doors, reinforcement also helps maintain energy efficiency.

Cost Factors for Standard 2 Car Garage Doors

Your budget plays a major role in selecting a standard 2 car garage door. Understanding the full cost picture helps avoid surprises.

Price Ranges Based on Size and Materials

Average costs for 16×7 foot doors by material 

The standard 16×7 two-car garage door price varies significantly based on materials. Let's break down typical costs:

Premium options and their price points 

Premium features add to the base cost of standard 2 car garage doors. These might include:

· Designer window patterns ($200-$800 extra)

· Custom colors ($150-$500 extra)

· High-R-value insulation ($200-$600 extra)

· Decorative hardware ($50-$300 extra)

Budget considerations for different households 

How much should you spend? A good rule of thumb: invest 1-2% of your home's value in your garage door. This ensures appropriate quality without overspending.

For a $300,000 home, consider budgeting $3,000-$6,000 for a quality door and installation. The investment makes sense given the door's impact on curb appeal and home value.

Additional Expenses to Consider

Opener systems suitable for double-width doors 

Standard 2 car garage doors require proper opener systems. These heavy doors need openers with adequate horsepower:

· 1/2 HP: Sufficient for lightweight doors

· 3/4 HP: Recommended for most 16-foot doors

· 1+ HP: Best for heavily insulated or custom wood doors

Expect to spend $300-$700 for a quality opener system with safety features and smart connectivity.

Installation costs and potential structural modifications 

Professional installation typically ranges from $300-$800 for standard sizes. Complex installations or structural modifications add significantly to this cost.

Potential additional expenses include:

· Header replacement ($500-$2,500)

· Center post removal and reinforcement ($1,000-$3,000)

· Electrical work for opener ($200-$500)

· Disposal of old door ($100-$200)

Long-term maintenance expenses 

Factor in ongoing maintenance costs when budgeting. Steel doors need minimal upkeep, while wood requires regular refinishing. Annual professional tune-ups cost $75-$200 and help extend your door's lifespan.

Upgrading from Non-Standard to Standard 2 Car Garage Door Sizes

Many homeowners consider upgrading unusual garage door openings to standard sizes. This renovation improves functionality and market appeal.

Renovation Considerations

Assessing if your current opening can accommodate a standard size 

First, determine if your garage can physically fit a standard 2 car garage door. Measure your current opening and compare it to standard 16×7 dimensions.

Key questions to answer:

· Is the opening width at least 16 feet or easily expandable?

· Is there adequate headroom (12-15 inches minimum)?

· Do side walls provide enough clearance (4+ inches each)?

· Is the garage deep enough for the door's travel path?

Structural modifications that might be necessary 

Converting to a standard size often requires significant structural work. Common modifications include:

· Widening the door opening (requires header replacement)

· Raising the header height for taller doors

· Reinforcing side supports for wider openings

· Adjusting ceiling structures for track systems

These changes can add $2,000-$5,000 to your project costs. Always work with qualified contractors for structural modifications.
