Size of a 3 Car Garage

When deciding to build or purchase a 3 car garage, it’s essential to know the correct size to make sure it accommodates your vehicles accurately.

To calculate the square footage of your 3 car garage, follow these simple steps:

Step 1: Measure the Width

Measure the width of the garage by locating the two walls perpendicular to each other along the length of the garage. These two walls represent the width of the garage.

Step 2: Measure the Depth

Measure the depth by locating the two walls parallel to each other and perpendicular to the width of the garage. These two walls represent the depth of the garage.

Step 3: Calculate the Total Square Footage

Multiply the width (in feet) by the depth (in feet) to determine the total square footage of the garage.

It’s also important to consider any additional spaces you may want in your garage.

This can include storage spaces, workbenches, laundry or mudrooms, and other amenities. By adding these additional spaces, you can determine the recommended square footage required for your needs.

Importance of Considering Space for Each Car

To park a car in a garage comfortably, you need a standard size garage of at least 12 feet wide by 20 feet deep. For a 3 car garage, this would mean a space of at least 36-48 feet wide by 60-72 feet deep.

Still, this size can vary depending on the width and length of your vehicles. It’s important to account for these variations to ensure you have ample space for the vehicles to park safely and comfortably.

By doing so, you will also leave room for circulation space to move around the parked vehicles and other functional spaces in your garage.

Renovating a 3 Car Garage

If you have a garage that needs some upgrading, renovation can maximize the functionality and aesthetic appeal of your space. Before embarking on any garage renovation project, it’s crucial to consider your needs, available square footage, and budget.

Here are some factors to consider when planning a 3 car garage renovation. 1.

Size and Layout

A garage’s size and layout play a critical role in its functionality. When planning your renovation, take into consideration the space available and how you can utilize it best.

Think about the size of your vehicles and ensure that parking spaces leave sufficient space for opening car doors. You might want to work with a professional garage designer or architect to help create the most efficient and effective layout for your space.

2. Storage Needs

Most homeowners use their garages as storage spaces, so adequate storage options should be included in your renovation plans.

You may consider wall storage, modular storage systems, or multi-functional furniture like workbenches with built-in cabinets to maximize storage space. Keep in mind that the garage needs to be cleared of all clutter and unwanted items before work begins.

3. Additional Features

If you plan to spend more time in your garage than just parking your cars, you may want to include amenities like a laundry area, a half or full bathroom, or a workshop space to accommodate your hobbies.

You may also incorporate racks for sports equipment or a bike stand for a bike collection. 4.

Lighting and Ventilation

Make sure your garage has adequate ventilation and lighting. Good ventilation helps to regulate temperature, remove harmful chemicals, and eliminate dampness.

Many garage renovation projects focus on improving energy efficiency, with the installation of insulation and thermal barrier systems. Adequate lighting, such as LED lighting, enhances visibility and promotes safety.

5. Finishes and Materials

When planning your garage renovation project, consider the different finishes and materials to use.

You might consider most of the sealing of the floors or installing of an epoxy coating to protect and add value to your space. You might also focus on the walls and ceiling with paint or storage systems to add an aesthetic appeal to your new garage’s look.

6. Hiring a Professional

It’s crucial to work with a professional when renovating your garage.

They can help you plan the layout better, recommend cost-effective materials and finishes, and oversee the project to make sure it goes smoothly. A professional contractor can help ensure that your new garage meets the necessary building codes and is safe for use while protecting the resale value of your home.

Maximizing Square Footage

One of the most important aspects of your garage renovation will be maximizing the available square footage. Here are some tips to maximize your garage space:


Use Vertical Space

Just like you would in a small apartment, use your garage’s vertical space by installing overhead or wall-mounted storage. This frees up valuable floor space and keeps your clutter organized and out of sight.

2. Wall Storage

Adding storage to the walls increases usable space in your garage.

Modular storage systems are versatile and can be customized to fit your specific needs. They allow you to hang items such as tools, ladders and may feature built-in cabinets and shelving.

3. Multi-Functional Furniture

Choose furniture and features that perform more than one function.

Look for workbenches with storage, fold-down tables, or benches, or custom-built cabinets that feature storage and a work area. 4.

Mezzanine Installation

Mezzanine installation increases usable square footage in your garage. A mezzanine system can be as small or as large as you need, and it’s an excellent way to make better use of the vertical space in your garage.

It also offers space for storage or work, and can be used for entertaining when needed.


In conclusion, finding the right size for your 3 car garage may seem daunting, but it’s essential to make sure it serves your needs adequately. Additionally, renovating your garage involves careful planning, maximizing square footage, and investing in high-quality finishes to add value to your home.

With these tips, you can create a beautiful and functional space that keeps your vehicles safe while enhancing storage and usable square footage. A 3 Car Garage with a Car Lift: Size and Other Considerations

If you’re a car enthusiast or a mechanic, a car lift can make working on your vehicles much easier.

However, it’s essential to consider the size of your garage before installing a car lift. Let’s explore how much square footage is needed for different types of car lifts and some other important things to consider when installing a car lift.

Square Footage of a 3 Car Garage with a Car Lift

Car lifts can take up varying amounts of space, depending on the type of lift you choose. Two of the most common types of car lifts are two-post lifts and four-post lifts.

The two-post lift will need an area of about 20-25 square feet to fit it comfortably, while the four-post lift will need about 40-50 square feet. It’s essential to take note of the lift height as the overhead may influence the total height of the garage, and if it has adequate clearance.

Damaging your garage roof or ceiling due to improper measurements will be costly, and therefore, you should avoid it at all costs. You might also want to consult with a professional designer or architect to ensure that your garage space accommodates the size of the car lift, fits your specific needs, and complements the layout of your garage.

Considering Car Lift Height

Many car lifts are tall and require a garage with sufficient ceiling clearance. A standard 3 car garage has a height of about 8-9 feet, which is not enough to accommodate a car lift.

It’s crucial to note the headroom your car lift requires to ensure it fits in the garage you intend to install it.

Consulting a Professional Designer or Architect

It’s essential to consult a professional garage designer or architect when considering installing a car lift. They can help you determine if your garage is large enough for a car lift and design the best layout to ensure an efficient and safe working space.

Calculating Square Footage for Insurance Purposes

Another important aspect to consider is the accurate calculation of square footage for insurance purposes. Here are the steps to follow:

Step 1: Measure the Length and Width

By using a measuring tape, measure the length and width of your garage space and write down the figures in feet.

If your garage has an irregular shape, break the garage into smaller, more regular areas, and measure those individually. Step 2: Multiply to Get Total Square Footage

Multiply the length by the width to determine the total square footage of the garage.

Step 3: Consider Any Irregular Shapes or Features

Consider any irregular shapes or features like alcoves, storage areas, or utility closets within the garage space. These areas should be measured separately and included in the total square footage calculation.

Importance of Accuracy in Calculation for Insurance Purposes

Accurately calculating your garage’s square footage is crucial when determining the value of your property for insurance purposes. Failing to do so may lead to discrepancies that can result in underpayment or overpayment of coverage costs.

This can lead to disputes with your insurance company and may impact your ability to get adequate coverage in case of a loss or damage. In conclusion, installing a car lift in your garage can enhance your car maintenance workflow.

However, you need to ensure that you have adequate space and that your garage’s layout allows for the installation of the car lift. Also, an accurate calculation of your garage’s square footage is crucial for insurance purposes.

By following these guidelines, you can enjoy your car lift without any stress or hassle. A 3 Car Garage with a Mezzanine: Square Footage and

Safety Considerations

A mezzanine can be a fantastic addition to a 3 car garage to maximize the usable space.

However, it is essential to consider the size of your garage, the intended use for the mezzanine, and other safety considerations.

Square Footage of a 3 Car Garage with a Mezzanine

The size of a mezzanine depends on the intended use, available space, and other essential factors. Generally, a mezzanine may take up an area of around 200-400 square feet, although the size can vary depending on the specific dimensions and size of the mezzanine.

Before adding a mezzanine, it’s imperative to ensure that it will fit comfortably and that it won’t be overly crowded. Keep in mind that the intention of the mezzanine may require additional space for movement or equipment, and it’s essential to account for this.

Safety Considerations

When designing and constructing a mezzanine, several safety considerations must be taken into account. Here are some things to consider:


Height of the Garage

The height of the garage will determine the height of the mezzanine. To meet code requirements, a minimum of 7.5 feet of height clearance is required.

Keep in mind that the installation of a mezzanine will reduce the head clearance below it. Make sure that there is sufficient overhang distance above the mezzanine to ensure that you will not hit your head on the ceiling when standing on the mezzanine.

2. Weight Capacity of the Mezzanine

The weight capacity of the mezzanine will be a critical factor in its design and installation.

It’s essential to ensure that it can support the intended load capacity without exceeding its weight limits. A structural engineer can assist in calculating to determine the correct weight capacity.

3. Accessibility

Accessibility is another crucial factor to consider when designing your mezzanine.

You may opt for either a permanent stair or ladder, to enable you to move up and down easily and safely. Keep in mind that you will need enough floor space to place the stairs or ladder.

Consulting with a Professional Designer or Architect

It’s highly recommended to consult with a professional designer or architect when designing your mezzanine. They can help you determine the right size and layout for your garage space and ensure that all safety considerations are met.

They can also help you determine the right weight capacity for your mezzanine to ensure that it is safe to use. In conclusion, adding a mezzanine to your 3 car garage can be a great way to maximize the usable space, but it’s important to consider safety and other essential factors.
