What Are the Standard Garage Door Sizes?

Standard garage door sizes range from 8×7 feet to 20×8 feet, with 9×7 feet being the most common single-car size in the United States. Single-car doors measure 8-10 feet wide and 7-8 feet high. Narrower doors fit compact cars and sedans, while taller or wider options such as 8×8, 9×8, and 10×8 provide extra clearance for SUVs, pickup trucks, and roof-mounted accessories. Two-car garage doors range from 12-20 feet wide and 7-8 feet high, with 16×7 being the most popular. 

For larger vehicles, RV and oversized garage doors span 10-14 feet wide and 12-16 feet high, accommodating motorhomes, trailers, lifted trucks, and other high-profile vehicles with extra clearance for mirrors, roof racks, and cargo. Commercial garage door sizes start at 8×7 feet for single doors and 16×7 feet for double doors, with taller or wider options used in service stations, warehouses, and industrial facilities to allow safe access for trucks and equipment. This full range of garage door sizes ensures nearly every vehicle and garage type is accommodated efficiently.

What Are the Standard Single Car Garage Door Sizes?

Standard single car garage door sizes range from 8 to 10 feet wide and 7 to 8 feet high, with 8′ × 7′ and 9′ × 7′ being the most common options. Narrower doors fit compact vehicles, while wider and taller options provide additional clearance for SUVs, pickup trucks, and storage needs.

Here is a table highlighting different standard single-car garage door sizes:

Sing Car Garage Door Size	Vehicle Fit	Common Application
8′ × 7′	Compact cars, sedans	Older homes and smaller garages
8′ × 8′	Taller vehicles	Additional vertical clearance
9′ × 7′	Sedans, crossover SUVs	Most common residential garage door size
9′ × 8′	SUVs with roof racks	Increased headroom and easier access
10′ × 8′	Trucks, vans, larger vehicles	Extra width and height clearance

8×7 Garage Door

An 8×7 garage door is a standard single-car residential size, measuring 8 feet wide by 7 feet tall (or 96 inches by 84 inches), making it an ideal choice for compact suburban properties or historic homes with limited space. To ensure a seamless installation and a proper weather seal, the rough opening framed into the garage wall must be 96 inches wide and 84 inches high to accommodate a standard 2-inch-thick door panel. While this garage door setup comfortably fits small cars, compact SUVs, and basic household storage, homeowners comparing alternative single-car garage door sizes can consider a 9×7 door or choose 8×8- or 9×8-inch variations.

8×8 Garage Door

Measuring at 96 inches wide by 96 inches high, an 8×8 garage door is a standard single-car sizing option engineered specifically for homeowners who require significant vertical clearance without expanding the horizontal footprint of their garage bay. This specialized dimension is frequently used in detached garages, custom residential builds, and workshop sheds where standard 8×7 or 9×7 options lack sufficient overhead clearance for tall equipment. The primary advantage of this garage door size is its ability to comfortably clear taller modern vehicles, such as lifted SUVs, four-wheel-drive trucks, or commercial work vans equipped with permanent roof racks. 

9×7 Garage Door

A 9×7 garage door is the most common industry-standard single-car garage door size in the United States, measuring 9 feet wide (108 inches) by 7 feet tall (84 inches). Sitting squarely within the single-car dimensions of 8 to 10 feet wide and 7 to 8 feet tall, this configuration accommodates virtually all modern sedans, crossovers, and small SUVs with ease. The benefit of selecting a 9×7 garage door over an 8×7 variant is the extra width it provides, which allows drivers to safely open vehicle doors inside the garage bay and navigate entry without scraping side-view mirrors.

9×8 Garage Door

A 9×8 garage door is a standard residential single-car size tailored to fit the dimensions of modern full-size SUVs, crossovers, and light-duty work trucks. This garage door size offers an optimal balance of parking ease and overhead storage capacity. While standard single-car garage door widths range from 8 to 10 feet, upgrading to an 8-foot height for this configuration meets the vertical clearance needs of vehicles equipped with roof racks, cargo shells, or lifted suspension kits. Successful installation of a 9×8 garage door requires a precisely framed rough with a minimum side clearance of 3 to 4.5 inches on each side to properly house the vertical tracks and structural brackets.

10×8 Garage Door

With a width of 10 feet and a height of 8 feet, a 10×8 garage door provides extra clearance for full-size pickup trucks, large SUVs, vans, and vehicles with roof-mounted accessories. The wider and taller opening makes parking easier while reducing the risk of contact with mirrors or roof racks. For proper installation of this garage door size, the rough opening should be 10 feet wide by 8 feet high. This garage door size is also a practical choice for homeowners who need additional space for equipment storage or walk-through access.

What Are the Standard Two-Car Garage Door Sizes?

Standard two-car garage door sizes range from 12 to 20 feet wide and 7 to 8 feet high, with 16×7 being the most common size for residential garages. These garage door sizes provide enough space for two vehicles parked side by side, while wider options offer additional clearance for larger trucks, SUVs, and storage needs.

Below is the table highlighting different standard two-car garage door sizes:

Two Car Garage Door Size	Vehicle Fit	Common Application
12′ × 7′	Two compact cars	Smaller double-car garages with limited wall space
14′ × 7′	Compact and midsize vehicles	Homes requiring more parking clearance than a 12-foot door
16′ × 7′	Sedans, SUVs, pickup trucks	Most common residential double garage door size
16′ × 8′	SUVs, trucks with roof racks	Additional vertical clearance and modern garage designs
18′ × 7′ or 18′ × 8′	Full-size trucks and large SUVs	Easier vehicle access and extra parking space
20′ × 7′ or 20′ × 8′	Oversized vehicles, trailers, storage access	Maximum residential width for flexibility and convenience

12-Foot Garage Door

A 12-foot garage door is a practical option within the range of standard two-car garage door sizes, used in smaller two-car garages or spaces designed for compact vehicles and storage. This width accommodates two smaller cars side by side while still allowing room for maneuvering and basic storage. When selecting a 12-foot door, consider vehicle dimensions, storage needs, and available headroom and side clearance. Larger vehicles may require wider doors, and building codes or limited interior space can affect installation. Evaluating these factors ensures the door provides a safe, functional, and well-fitted solution for your garage.

14-Foot Garage Door

For garages that require extra width, a 14-foot garage door provides ample space while remaining within the limits of your available structure. A 14-foot garage door is ideal for garages accommodating two mid-size vehicles side by side, providing additional maneuvering room and storage along the sides. Choosing this garage door size starts with accurately measuring the interior width, depth, and overhead height of your garage to ensure the door panels and track system fit correctly. Precise measurements prevent framing conflicts, misaligned tracks, and operational issues, ensuring safe and reliable garage door performance.

16×7 Garage Door

The 16×7 garage door is the standard double-car size for residential garages, offering ample space for two vehicles. Its installation is primarily determined by the garage door opening width, which is the clear horizontal distance between the finished interior sides of the garage frame. This measurement establishes the maximum width of the door panels that can be safely mounted while clearing the entry threshold. To ensure an accurate fit, a professional technician measures from the left finished jamb to the right, selecting a door width that matches or slightly exceeds the opening. This approach guarantees a proper weather seal and allows the door to operate smoothly along its tracks.

16×8 Garage Door

A 16×8 garage door is a taller, upgraded option for standard two-car residential garages, commonly used in homes with SUVs, trucks, or vehicles that require extra vertical clearance. Its installation is determined by the garage door opening height and the clear vertical distance from the finished floor to the lowest point of the structural header. This measurement sets the maximum height the door system can occupy. Accurate measurement from the floor to the bottom of the header ensures the door panel transitions smoothly from closed to open. This extra height provides safe clearance for taller vehicles while maintaining the door’s efficient operation.

18-Foot Garage Door

An 18-foot garage door is an ultra-wide residential option commonly used in homes with larger vehicles or garages that require additional maneuvering space. This garage door size provides ample clearance for two full-size vehicles and ensures easy entry, exit, and movement within the garage. Determining the required clearance involves adding a safety margin to the width of your largest vehicle, accounting for exterior accessories such as wide mirrors, roof racks, or cargo pods. Properly calculating this buffer prevents scraping, collisions, or operational issues, ensuring safe and smooth daily use of the garage door.

20-Foot Garage Door

For homeowners seeking maximum width, a 20-foot garage door offers a luxury double-car setup ideal for oversized vehicles, high-end SUVs, or garages that require extra space for multiple vehicles or storage. This size is often used in custom residential garages, homes with large driveways, or estates where extra maneuvering room is needed. Installing a 20-foot door depends heavily on ceiling height, the total vertical clearance above the door opening required to accommodate tracks, torsion springs, and automatic opener systems. Accurately measuring this overhead space is essential, as insufficient or obstructed headroom can prevent proper installation and compromise safe operation.

What Are the Standard RV and Oversized Garage Door Sizes?

Standard RV and oversized garage door sizes range from 10 to 14 feet wide and 12 to 16 feet high, depending on the vehicle being stored. Unlike standard garage door sizes, these larger doors are designed to accommodate RVs, motorhomes, oversized trucks, boats, and trailers while providing additional clearance for safe maneuvering. As a general guideline, allow at least 12 inches of height clearance and 18 inches of width clearance beyond the vehicle’s dimensions.

10×10 Garage Door

The 10×10 garage door is ideal for larger personal vehicles, work vans, and lifted SUVs, providing both extra width and height compared to standard single-car doors. Its dimensions allow safe entry and exit for high-profile vehicles while also accommodating roof-mounted accessories like cargo carriers or ladder racks. Installation requires a precisely framed rough opening of 10′ × 10′, with 12-15 inches of headroom and 4-5 inches of side clearance to properly fit the track system and hardware. This garage door size also provides additional vertical storage space and flexibility for maneuvering tools or equipment, making it suitable for residential garages that store oversized vehicles or light commercial vehicles.

10×12 Garage Door

A 10×12 garage door is suited for tall RVs, large trailers, and commercial work trucks that exceed standard residential clearances. The extra height requires high-lift track systems and heavy-duty hardware to ensure safe and smooth operation. At 10 feet wide and 12 feet tall, it provides enough room for vehicles with roof-mounted ladders, awnings, or accessories, as well as recreational equipment in residential garages. Compared with standard single doors (8-10′ wide × 7-8′ high) and double doors (16′ × 7-8′), this size gives extra vertical clearance critical for avoiding scraping or damage, making it a practical solution for homeowners or light commercial users with specialized vehicle needs.

12×12 Garage Door

The 12×12 garage door is a versatile oversized option used for RV storage, farm equipment, large boats, or Class C motorhomes. Its generous width and height allow wide-body vehicles to enter safely while leaving ample room on the sides for mirrors, roof racks, and walking clearance. Standard in light commercial settings, this garage door size supports easy movement of equipment and provides flexibility for storing additional items behind vehicles. Installing a 12×12 garage door requires ensuring that the rough opening, headroom, and side room can accommodate heavy-duty track systems and panels. 

12×14 Garage Door

The 12×14 garage door is designed for extremely tall or wide vehicles, including Class A RVs, trailers, or commercial machinery. Its expansive dimensions allow for easy clearance of roof-mounted ladders, cargo carriers, or wide mirrors while also providing significant overhead and side room for vehicle maneuvering. Proper installation requires careful verification of headroom, backroom, and side clearance to accommodate heavy-duty vertical tracks and commercial-grade automatic openers. This garage door size is best for homeowners or businesses anticipating long-term storage needs, future vehicle upgrades, or specialized equipment that cannot fit through standard garage doors, making it a top choice for maximum accessibility and flexibility.

What Are the Standard Commercial Garage Door Sizes?

The standard commercial garage door sizes range from 8′ × 7′ for single doors to 16′ × 7′ for double doors, though many commercial facilities require larger openings to accommodate trucks, equipment, and high-traffic operations. A 7-foot-high door fits most passenger vehicles, while 8-foot or taller doors are better suited for vans, trucks, and vehicles with roof-mounted accessories. For proper installation and operation, commercial garage doors require 10-12 inches of headroom and 4.5-5 inches of side room.

Service Station and Auto Shop Garage Door Size

Service station and auto shop garage doors range from 10-12 feet wide and 10-14 feet tall to accommodate passenger vehicles and commercial lifts. These garage doors fall into three thickness categories: Basic (1/8″-1/2″), Heavy-Duty (1/2″-1″), and Well-Insulated (1.5″-2″+), which affect durability and thermal efficiency. Standard panel heights range from 18 to 24 inches and can be customized with various architectural styles. Choosing the right thickness and insulation ensures energy efficiency, withstands high-frequency use, and maintains smooth daily operation.

Warehouse and Loading Dock Garage Door Size

Designed for commercial freight vehicles, warehouse and loading dock garage doors measure 8-10 feet wide and 8-10 feet tall. Proper installation begins with measuring the clear width, height, side room, and headroom to ensure the track system fits correctly. Adding a 1-inch safety margin to each side of the rough opening helps achieve an airtight weather seal. For comparison, standard residential single-car doors are 8-9 feet wide by 7-8 feet high, while double-car doors measure 16 feet wide by 7-8 feet high.

Industrial and Semi-Truck Garage Door Size

Industrial and semi-truck garage doors measure 12-14 feet wide and 14-16 feet tall to accommodate oversized trucks, trailers, and heavy equipment. These garage doors are built for frequent use in warehouses, distribution centers, and industrial facilities, requiring robust construction and precise installation. Choosing a qualified garage door technician with proper licensing, insurance, a labor warranty, and experience with large-scale doors ensures smooth operation, minimal downtime, and safe access for vehicles and equipment.

What Are the Standard Garage Door Sizes by Vehicle Type?

The standard garage door sizes by vehicle type range from 8′ × 7′ to 12′ × 14′, depending on the vehicle’s size and type. These garage door sizes are designed to match the dimensions of common vehicles while providing sufficient clearance for doors and roof accessories, and for safe maneuvering within the garage.

Garage Door Size for Sedans and Small Cars

Garage door sizes for sedans and small cars are 8 feet wide by 7 feet high and 9 feet wide by 7 feet high. An 8-foot-wide opening neatly accommodates compact vehicles, coupes, and small subcompact cars, making it a highly practical choice for properties with limited structural footprints. A 9-foot-wide opening serves as a highly versatile alternative, providing ample side buffer for standard passenger vehicles and small crossovers and reducing the risk of scraping side mirrors. 

Garage Door Size for SUVs and Pickup Trucks

Garage door size for SUVs and pickup trucks is 10 feet wide by 8 feet high for a single-car bay and 18 feet wide by 8 feet high for a double-car layout. These garage door dimensions provide sufficient clearance for wide tow mirrors, roof racks, and larger cargo boxes, allowing vehicles to enter and exit safely. For heavily modified or lifted vehicles, custom door sizes may be necessary to accommodate extra height or width beyond standard utility vehicle dimensions.

Garage Door Size for Lifted Trucks

Garage door size for lifted trucks is 10 feet wide by 8-9 feet high, depending on the vehicle’s lift and tire size. Standard 7-foot-high residential doors are too short to clear high-clearance suspensions safely, and typical 8-9-foot widths are inadequate for trucks with oversized tires or roof-mounted accessories. A taller door provides the necessary clearance to avoid contact with the overhead panels.

Garage Door Size for Vans and Campers

Garage door size for vans and campers is 10-12 feet wide by 10-14 feet high, depending on the vehicle’s profile and accessories. Smaller low-profile camper vans may fit specialized 8-foot-high openings, but high-roof commercial vans and Class C motorhomes benefit from at least a 12×12-foot footprint to prevent side scrapes and overhead contact. Custom or oversized doors are required for safe access.

How Do You Measure for a Standard Garage Door?

To measure for a standard garage door, measure width, height, and the space available for tracks, headroom, and backroom. Accurate measurements ensure the door fits properly, allows safe vehicle entry, and provides enough clearance for smooth operation of the tracks and opener.

Key factors to measure for a standard garage door are:

1. Garage Door Width: Measure the distance between the inside of the left and right door jambs at the widest point. Take several measurements to account for any bowing. Standard single doors are 8, 9, or 10 feet wide, while double doors are 16 feet wide.
2. Garage Door Height: Measure from the concrete floor to the underside of the header on the left, middle, and right sides, using the smallest measurement. Standard heights are 7 feet, with 8-foot doors becoming more common in modern garages.
3. Rough Opening: The framed space in the wall where the door will be installed. Both width and height must match the door size to ensure proper sealing and smooth operation.
4. Headroom: Measure the distance from the top of the opening to the ceiling or lowest overhead obstruction. Standard tracks require 10-12 inches, with an extra 3 inches if installing an automatic opener.
5. Side Room: Check the flat space on each side of the opening. Most vertical track systems need 3.5-5.5 inches per side. For two-car garages with separate doors, allow at least 10 inches on the center post.

When Should You Choose a Custom Garage Door Size?

You should choose a custom garage door size if you have oversized vehicles, non-standard garage openings, workshop garages, extra-tall vehicles, or large storage access needs. Carefully evaluating these factors and consulting with professional garage door service providers ensures that your garage door fits your space, safely accommodates your vehicles, and meets your long-term functional or storage requirements.

Choose a custom garage door size if you have:

• Oversized Vehicles: Vehicles such as lifted trucks, RVs, large vans, or boats exceed standard residential entry widths, making a custom garage door size necessary to avoid scraping side mirrors or damaging exterior bodywork during transit.
• Non-Standard Garage Openings: Older homes, historic properties, or unique architectural designs may have asymmetrical, warped, or unusually sized openings. A custom garage door ensures a precise and secure fit.
• Workshop Garages: Garages used for hobbies, workshops, or storage may require wider or taller doors to allow vehicles and equipment to move freely without obstruction.
• Extra-Tall Vehicle Clearance: High-profile vehicles, such as RVs or lifted trucks, require vertical clearance beyond the standard 7- or 8-foot door height. Custom sizing prevents damage and allows easy access.
• Large Storage Access Needs: If you regularly move bulky items, recreational equipment, or multiple vehicles in and out of the garage, custom widths or heights maximize usability and convenience.

How Do You Go From the Right Size to the Right Door?

To go from the right size to the right door, start by matching your measured garage opening dimensions, including width, height, headroom, and side room, to the available standard or custom garage door options. Selecting a door that aligns with your measurements and clearance requirements ensures safe operation, a proper fit, and long-lasting performance.

Steps to choose the right door from the right size:

• Compare Dimensions: Match your garage opening measurements to standard or custom door sizes.
• Allow Clearance: Choose a door slightly larger than the opening for proper sealing and smooth movement.
• Check Headroom: Standard vertical track systems require 10-12 inches; automatic openers need an additional 3 inches.
• Check Side Room: Ensure 3.75-5.5 inches per side for track installation and safe operation.
• Finalize Selection: Confirm that the door fits your space, safely accommodates vehicles, and meets your functional needs.
