Choosing A Garage Size

By Jill Siragusa, 11/01/2014 - 5:15pm

We get phone calls almost every day from customers looking for a quote on a garage… but they don’t know what size they want!

For the sake of comparison, the most common sizes for garages are 12 x 24, 14 x 28, 20 x 20, and 24 x 24. There are two factors to consider when determining what size garage you need: what size vehicle(s) you’ll park and how much extra storage or work space you want.

If you’ve got a tape measure handy, the best thing you can do is go out and measure your vehicle. Allow whatever room you want to walk around the car, then whatever you might need for storage. Keep in mind that our buildings are measured to the outside, so the interior dimension will be slightly smaller.

The minimum suggested building lengths for different types of cars are as follows:
• Small pickup truck: 18’
• Full pickup truck, SUV, or van: 20’ or 22’

For storage, allow at least 4’ if you are looking to store small things like bikes or tools. For more storage or for a workbench and work area, add about 10’. A 24’ – 28’ building will accommodate a regular-sized vehicle and a work area. And keep in mind if you want a workbench, Horizon can install it for you! A 24” deep workbench is an inexpensive addition. For storage of larger things like mowers or ATVs, a 32’ or longer building will provide enough room.

Width is the other dimension to consider. Our single garages come in 10’, 12’, and 14’ widths. 10’ may be small for anything besides compact cars or motorcycles; 12’ and 14’ are more common. For double-wide garages, we can do 20’, 24’, or 28’. Be aware, however, that 14’ and 28’ wide buildings cost quite a bit more to ship than the other widths.

A garage is an investment in your property. Make sure you get the right size.

Width also affects the size of the overhead doors. An 8’ wide x 6’6” high door is put on 10’ and 20’ wide buildings. A 9’ wide x 7’ high door goes with 12’, 14’, 24’, and 28’ structures. For a small upcharge, a 10’ wide x 7’ high door may be installed on 14’ and 28’ wide garages.

Remember that any size garage is also available in a two-story version. So consider building up instead! A garage attic can come with a full staircase and rail, and the floor extends all the way across the building to effectively double your space. You can keep a standard A-frame roofline, or enhance the useable space and appearance even more with a gambrel roof or two different styles of dormers.

Beware of garage apartment plans you may see online. When it's all said and done, you may be further ahead in both time and money by going the PRE Built Garage or prefabricated garage apartment combination route.

We hope this article has been helpful for you in planning your garage. When in doubt, remember bigger is better when planning for a garage and storage space. You won’t be sorry to have extra breathing room. And if you have any other questions, just let us know!
