If you’re planning to build a new home or renovate an existing space, a common question is, what is the size of a standard two car garage. A standard two-car garage size is designed to accommodate most modern sedans and SUVs, typically requiring a minimum width of 20 feet. However, that’s just the starting point, and many factors can influence the final dimensions you’ll need.
This guide will walk you through everything you need to know about two-car garage dimensions. We’ll cover the standard measurements, explain why you might want to go bigger, and discuss important considerations for doors, storage, and functionality.
What Is The Size Of A Standard Two Car Garage
The most commonly cited standard size for a two-car garage is 20 feet wide by 20 feet deep. This 20’x20′ footprint provides 400 square feet of space. For many years, this was the default specification for countless suburban homes, aimed at fitting two vehicles side-by-side with minimal extra room.
In practice, this size can feel quite tight with today’s larger vehicles. A typical midsize sedan is about 6 to 6.5 feet wide. Parking two of them in a 20-foot width leaves only about 7 feet of total space between them and the walls. This makes getting in and out of the cars a careful maneuver.
Because of this, the modern standard has shifted. Most new construction now uses more generous dimensions to provide comfort and utility.
The Modern Standard And Minimum Dimensions
Today, a more practical and widely accepted standard size is 24 feet wide by 24 feet deep. This 24’x24′ layout offers 576 square feet, a significant 176-square-foot increase over the older 20×20 standard. The extra space makes daily use much more comfortable.
Here is a breakdown of common two-car garage sizes you will encounter:
- Minimum/Adequate: 20′ W x 20′ D (400 sq ft)
- Modern Standard/Comfortable: 24′ W x 24′ D (576 sq ft)
- Spacious/With Storage: 26′ W x 26′ D (676 sq ft) or 28′ W x 24′ D (672 sq ft)
- Oversized/Workshop Potential: 30′ W x 30′ D (900 sq ft) or larger
The absolute minimum width for two car garage is generally considered 18 feet, but this is extremely cramped and only suitable for very small vehicles. It is not recommended for most homeowners.
Why Depth Is Just As Important As Width
While everyone worries about width, depth is a critical factor that’s often overlooked. A standard garage door is 16 feet wide. Behind that door, you need enough room for the vehicles themselves, plus space to walk in front of them and perhaps store items.
A 20-foot deep garage might fit your car, but once you account for storage shelves or a workbench at the front wall, space becomes limited. A depth of 22 to 24 feet is much more functional, allowing for a vehicle and clear walking space in front of it.
Consider the length of common vehicles:
- Compact Sedan: ~14-15 feet long
- Full-Size Sedan: ~16-17 feet long
- Midsize SUV: ~15-16 feet long
- Full-Size SUV/Truck: ~18-21 feet long
With a 24-foot depth, even a long truck can fit with several feet to spare for storage or movement.
Accounting For Door Swing And Storage
The usable space inside your garage is less than the total dimensions. You must account for the swing of car doors. This is the primary reason wider garages are better. You also need to consider the space taken up by wall thickness, insulation, and interior finishes.
The Impact Of Garage Door Size
The door opening itself dictates how easily you can drive in. A standard double garage door is 16 feet wide. For wider garages or for accommodating larger trucks, an 18-foot wide door is a smart upgrade. The height is also important; standard doors are 7 feet tall, but an 8-foot tall door is essential for larger SUVs or if you plan to add a roof rack.
Key Factors That Influence Your Ideal Garage Size
Choosing the right size involves more than just your cars. Think about how you will actually use the space both now and in the future.
Vehicle Sizes And Types
Measure your current vehicles. If you have two compact cars, a 20×22 garage might suffice. If you have a pickup truck and a large SUV, you should seriously consider a 26×26 or 28×24 layout. Remember to plan for future vehicle purchases, as cars tend to get larger over time.
Storage Needs And Workshop Space
For most people, the garage is the primary storage area for tools, holiday decorations, sporting equipment, and lawn care items. If you want shelving, cabinets, or a workbench, you need to allocate space for them. A good rule is to add at least 2-3 feet of depth or width for storage along a wall.
Local Building Codes And HOA Regulations
Always check your local building codes and any Homeowners Association (HOA) covenants. They may have specific requirements for garage size, setback from property lines, or even the appearance of the structure. These rules can limit your options or dictate a minimum size.
Budget And Property Constraints
Larger garages cost more to build due to increased materials and foundation work. Your property lot size and shape will also determine how big of a garage you can build. You need to maintain required setbacks from property lines and other structures.
Benefits Of Choosing A Larger Than Standard Garage
Opting for a garage that exceeds the minimum standard offers numerous advantages that enhance your home’s functionality and value.
- Improved Usability: Easy in-and-out access for passengers, especially children. No more squeezing along the side of your car.
- Adequate Storage: Dedicated space for bins, shelves, and cabinets without compromising parking space. This keeps your cars protected and your items organized.
- Workshop or Hobby Area: Space for a permanent workbench, tool chest, or area for hobbies like woodworking or crafting.
- Increased Home Value: A spacious, functional garage is a strong selling point. It appeals to buyers who need storage and see the potential for a workshop or gym.
- Future-Proofing: Accommodates larger future vehicles, additional freezers, or other large items you may acquire.
Many homeowners who build a standard 20×20 garage later regret not making it bigger. The incremental cost during initial construction is usually less than the cost and hassle of an addition later.
Planning Your Two Car Garage Layout
Once you’ve settled on dimensions, think about the internal layout. Good planning maximizes every square foot.
- Mark Your Vehicle Footprints: Use tape or chalk to outline the space your cars take up on the floor of the planned area. This gives you a visual of the remaining space.
- Plan Door Clearance: Ensure there is enough room for car doors to open fully without hitting walls, storage, or the other vehicle. At least 2-3 feet between vehicles is a good target.
- Designate Storage Walls: Decide which walls will host shelving, racks, or cabinets. The back wall is common, but side walls can be used if width allows.
- Consider Traffic Flow: Plan a clear path from the vehicle doors to the entry door into your house, especially important for carrying groceries.
- Electrical and Lighting: Plan for ample overhead lighting and numerous electrical outlets along the walls for tools, chargers, and garage door openers.
Including Additional Features
Think about other features you might want to include, such as a utility sink, a dedicated electric vehicle charging station, or enhanced insulation for climate control. Planning for these during construction is far simpler and cheaper than retrofitting them later.
Common Mistakes To Avoid When Sizing A Garage
Being aware of these frequent errors can save you from frustration down the road.
- Building to the Absolute Minimum: This is the number one mistake. It leaves no room for error, storage, or future needs.
- Ignoring Door Height: Forgetting to specify an 8-foot tall door can prevent you from parking a taller vehicle or using a roof-top cargo box.
- Forgetting About the Driveway: The garage is useless if the driveway approach is too steep or too narrow to easily maneuver cars into it.
- Poor Placement of Service Doors: The entry door from the garage into the house should be positioned for easy access, not blocked by a parked car.
- Neglecting Lighting and Ventilation: A dark, stuffy garage is unpleasant to use. Include windows or skylights and plan for good air circulation.

Is a 20×20 garage big enough for 2 cars?
A 20×20 garage can fit two average-sized cars, but it will be tight. It offers minimal space for opening doors or storing other items. For comfortable daily use, a larger size is highly recommended.
What is a good size for a 2 car garage with storage?
A good size for a two-car garage with storage is at least 24 feet wide by 26 feet deep (624 sq ft). Even better is 26 feet by 26 feet or 28 feet by 24 feet. This allows for parking two vehicles while dedicating an entire wall or the back area to shelving and cabinets.
How wide should a two car garage door be?
A standard two-car garage door is 16 feet wide. For larger vehicles or easier access, an 18-foot wide door is a valuable upgrade. The height should be at least 7 feet, with 8 feet being preferable for SUVs and trucks.
Can you fit 2 trucks in a standard 2 car garage?
It is very difficult to fit two full-size pickup trucks in a standard 20×20 garage. You would need a significantly oversized garage, such as 30 feet wide or more, to comfortably accommodate two large trucks with space to open doors and walk around.
Final Thoughts On Selecting Your Garage Size
Determining the right size for your two-car garage requires balancing your current needs, future plans, budget, and property limits. While the historical standard was 20×20 feet, the modern reality demands more space.
The most practical and popular choice for new builds is a 24×24 foot garage. It offers a great balance of cost and functionality. If your budget and lot allow, moving to a 26-foot width or depth provides a noticeable improvement in daily usability and storage capacity.
Take the time to carefully plan. Measure your vehicles, list your storage needs, and consult with your builder or contractor. Investing in a well-sized garage will pay off in convenience and satisfaction for as long as you own your home, and it will be a feature that future buyers will also appreciate. Remember, its almost always better to build a little bigger than you think you need right now.
