Sizing A Garage For Optimal Usage

Homeowners do not give much design attention to their garages because they don’t live in that space. After all, we only use it to shelter our cars, trucks, and sport utility vehicles (SUV). However, in the scheme of things, the garage is just as much an important aspect of good house design despite it being merely a car storage room. Whether it is an attached or detached garage, you should be just as deliberate with the use of the space when designing and sizing a garage.

The size of your motor vehicles should be considered in addition to the need for storage space when sizing a garage for optimal usage. There are typical sizes you can use for your garage. However, I will not go into minimum and maximum sizes because that is not the point of this article. If you are interested in that information, you can read our article on how to design a garage layout. What I am more concerned with here is the maneuvering between vehicles, storage and how to design the garage according to what will occupy its space.

Regardless of the size of your transportation unit, there should be enough room to enter and exit your car free from obstruction. I recommend at least 2′-6″ of minimum clearance between vehicles and the same on either side of each. I also suggest having at least two feet of clear space in front and back of the car. Keep in mind that this does not include space for storage.

Using vehicle dimensions when sizing a garage

Let’s take for example a family that has a Chevrolet Suburban SUV and a Ford Taurus midsize sedan. The SUV bumper to bumper length equal 222.40″ (approx. 18′-6″) and the width without door mirrors is 79.10″ (approx. 6′-7″). The midsize car length is 197.6″ (approx. 16′-5″) and the width is 73.0″ (approx. 6′-1″). These dimensions establish the basis by which the garage will be sized. Using the width of both vehicles, we add the aforementioned minimum clearance on the front, rear, and sides to get our interior parameters. So in this example, the garage interior dimensions should be at least 20′-2″ in width and 22′-6″ in length. These interior dimensions set the basis for expanding your garage space as you desire.

As with any aspect of home design, it all comes down to the math. Establish a minimum width and depth when sizing a garage. This will ensure that the space will work for your specific needs. You also avoid wasting valuable unheated square footage. If you plan to add storage (i.e. cabinets, lawn mower, bicycles, an extra refrigerator, freezer, etc.), consider adding an additional two feet minimum to the length or width of the garage. However, if your budget and available land space allows, you can expand as needed in order to size a garage for optimal usage.
