Common Garage Size Guide: How to Select the Best

So, you’re thinking of adding a garage to your property, but you’re not sure how big to make it? Obviously, you want the goldilocks of garage sizes – nothing too big or too small, and something that is just right for your budget.

Choosing the right garage dimensions maximizes space and functionality, ensuring your garage meets your needs now and in the future. With key factors influencing average garage dimensions like vehicle size, storage needs, and available space, how do you decide what size to pick?

Whether you need room for one car or three, considering these elements will help you select the best garage size for your lifestyle and property. Proper planning ensures your garage is a versatile, practical addition to your home – so let’s dive in!

Understanding Average Garage Size

The term “average garage size” can vary widely depending on where you look, but a detached garage can range anywhere from 12×18 to 28×40 with even larger custom dimensions available! Let’s break these common garage sizes down into some common categories.

Single Car Average Garage Sizes

For a single-car storage building, the average garage dimensions typically range from 12 to 16 feet in width and 20 to 24 feet in depth. This size is perfect for a standard vehicle with a bit of extra room for storage or a small workbench!

Double-Car Average Garage Dimensions

Double-car garages are often around 20 to 24 feet wide and 20 to 24 feet deep and are one of the most popular choices among homeowners. This common garage size provides ample space for two vehicles, with enough room to comfortably open car doors and move around. If you’re someone who enjoys tinkering with tools or needs additional storage space for bicycles, lawn equipment, or holiday decorations, a double-car garage might be the ideal choice.

Extra-Large Garage Sizes

For those with multiple vehicles or a desire for extra space, custom garages are the way to go. These garages typically measure 30 to 36 feet wide and 20 to 24 feet deep. Not only can you park three cars, but you also gain a significant amount of storage or workspace. This is an excellent option for hobbyists, car enthusiasts, or families with multiple drivers.

How to Determine Your Ideal Garage Size

As noted above, there are a lot of options in garage dimensions and sizes, ranging from small single-story options to massive additions. Sometimes, finding the right garage size is more complicated than just picking some numbers. To simplify the process, consider asking yourself the following questions to determine the garage dimensions that will best fit your space, budget, storage needs, and style.

  1. How Much Space Do You Have Available? Measure your available land to see what size garage will fit comfortably. It’s important to consider any zoning laws or building codes in your area that might affect the size of your garage. This will help you determine the maximum dimensions you can work with.
  2. What Is Your Budget? Larger garages will naturally cost more due to the additional materials and labor required. Determine your budget and find a balance between size and affordability. Keep in mind that investing in a slightly larger garage now could save you from needing an expansion later.
  3. Do You Have Future Plans That Might Affect Your Garage Needs? Think about your long-term plans. Will you be adding more vehicles to your household? Do you foresee needing additional storage space or a larger workspace in the future? Planning ahead can help you choose a garage size that will continue to meet your needs for years to come.
  4. What Is the Primary Use of Your Garage? Is your garage primarily for parking vehicles, or will it also serve as a workshop or storage area? If you plan to use it as a multifunctional space, consider how much room you’ll need for each function. A versatile design can make your garage more useful and enjoyable.
  5. How Much Room Do You Need to Move Around? Ensure there is enough space to comfortably open car doors and move around without bumping into anything. Additional space for walking around can make the garage more functional and enjoyable to use. Think about your daily routines and how much space you’ll need to maneuver easily.

By thoroughly considering these questions, you can make an informed decision on the ideal garage size for your specific needs and lifestyle. Of course, our garage experts are always available to help you select dimensions through our website or over the phone!

I am truly pleased with our garage built by Glick Woodworks. Daniel, David and the crew worked very quickly and professionally. I couldn't be happier with the building they crafted, and I know the addition of this garage has added value to our property. Special thanks to Derek for the hard work he put into removing, and moving, sheds all in one day during nonstop, steady rain.Very impressed!

We ordered a 24x24 two story gambrel shed/garage. Couldn’t be happier. They had great customer service throughout. I had some issues with permits and they got me all the documents I needed quickly. The crews that came to set it up did a fantastic job. The building is really made with quality materials. Would definitely recommend.

This is one stop shop. They came in and removed my 33 yr old (in (bad shape) shed, leveled out the pad location, bought in stone of at least 4 inches, outlined the new pad with 4x4's and bought in my new shed which was perfectly level. All of this in less than 7 hours. Very happy with the whole process!!!

I had my 12x24 Victorian shed installed yesterday. I can't say enough good words of the great customer service received by from Dave, Dan & the installers Amos, Jeff & Galen!Good quality craftmanship & price not bad either for the type of shed. They accommodated me by preparing the foundation & installing the shed all in one day because bad weather is expected today! Thank you men for a job well done! I definitely would highly recommend Glick Woodworks for anyone in the market for a shed!
