For most homeowners, having a garage is essential. Not only does it serve as a place for parking vehicles, but it can also be used to store tools, equipment, and other belongings. That said, determining the right size for your garage can be a daunting task. Do you need a two-car or three-car garage? Should it have a second floor or be attached or detached? These questions can only be answered based on your specific needs. But, in this blog post, we’ll provide tips on how to determine the right size for your garage.

Consider Your Parking Needs

The primary purpose of a garage is to park your vehicles. Determine the number of cars and the type of vehicles you have. If you have a larger pickup truck or SUV, it’s important to make sure the garage is tall enough to accommodate them. Also, take future purchases into consideration. You don’t want to build a garage that’s too small, only to find out later that it’s not sufficient for your needs. You don’t want to end up down the road purchasing a nice truck that you can’t park in your new garage.

A standard two car garage for small sized cars is a minimum of 20’x20’ for parking cars only. A 24’x24’ is recommended for ease of walking around the cars especially if you’re hauling groceries, kids in tow, or sports gear constantly in and out every day. A three car garage minimum is 32’x22’, but a 36’x24’ is recommended.

Think About Storage Needs

Apart from parking, a garage is also an excellent space for storage. Many homeowners use their garage to store seasonal items like holiday decorations, bicycles, and camping gear. Others store tools and equipment, workbenches, and other DIY essentials. If you’re planning to use your garage for storage, make sure you factor this in when determining the size. Consider building shelves or cabinets to maximize the storage space. By adding more square feet to the overall size of the garage leaving extra width on each car bay, then you’ll have some designated space for storage.

Draw out the dimensions on paper of the total square feet of the garage, and then measure your car or trucks width and length so you can visually see how much extra room is left over for getting in and out of your vehicles, and can you fit shelves or a work bench. Expand the dimensions to fit your needs and wants.

Determine The Level Of Functionality You Want

Not all garages are created equal. Some are basic and used only for parking, while others are more elaborate and have multiple functions. If you want to use your garage as a workspace or entertainment center, you’ll need to add extra square footage. A second floor is typically a great option for those who want to add extra space.

While you’re asking yourself all these questions about how you want to use the garage, and you realize that you do want some extra space for DIY projects, or car mechanic work and maintenance projects, or simply you could really use some serious extra storage space. You might consider going with a three car garage, leaving the third bay for projects and storage. Or, you could add a second story and have an entire room with windows and maybe a deck overlooking your property. Now you’re really thinking about how a whole room could add to your lifestyle and future needs. Buying a garage is a pretty big investment that will add value to your life and home. Definitely take the time to make it perfect.


Consider Whether You Want An Attached Or Detached Garage

Another important consideration is whether you want an attached or detached garage. If you live in an area with extreme temperatures, an attached garage may be your best option, as you’ll avoid stepping outside during harsh weather. Detached garages offer more privacy and can enhance the aesthetics of your property. They also give homeowners more flexibility in terms of design and size.

If you already have a one car garage attached to your house or you have a split entry style home that has a garage under it already then you might be thinking about adding more garage space to your property. You could add a detached garage off to the side and turn your one existing garage into a more usable house space like a home office or gym. Now that would be adding more interior square feet and the value of a detached garage.

Consult With A Professional

Finally, it’s always a good idea to consult with a professional before making any decisions. A builder or architect can help you determine the right size and design based on your specific needs. They can also provide insight into zoning restrictions, building codes, and other considerations you may not be aware of. It’s never recommended to just simply build a garage without the right permits, as they will make you take it down eventually.  Besides consulting with a professional garage builder, you’ll find answers to questions and opportunities for customization that you’d never have thought to ask about.


In conclusion, determining the right size for your garage depends on several factors. Consider your parking needs, storage requirements, and the level of functionality you want. Choose between an attached or detached garage based on your preferences and area restrictions. Finally, consult with a professional to ensure that your garage is not only functional but also aesthetically pleasing and meets all necessary building codes. With these tips, you’ll be well on your way to creating the perfect garage for your home.
