When it comes to buying a new garage door or putting one in a new home, size makes a big difference.

For instance, we have a two-bay garage with two single garage doors.  They are very narrow.  We’ve already lost a side-view mirror backing out.  We only have a couple of inches to spare.

If I were to build a house from scratch or a new garage, I’d go with wider garage doors because I like the space.

Regardless, below are your options for various garage door dimensions depending on the type of garage and garage size.

Garage doors, being plural, can be twice the size of a single garage door plus about three feet of space between the vehicles parked in the garage. Alternatively, with proper structural support between them, two identical doors can be hung side by side.

Standard garage doors are 8 feet wide by 7 feet tall. Larger doors are common and available for garages which are intended to house vans, SUVs, boats, RVs, or heavy work trucks.

Double Garage Door Sizes

Double sized garage doors can be twice the size of a single garage door plus about three feet of space between the vehicles parked in the garage. Such doors can be convenient as opening for a large space, but consideration is the door is much heavier and is going to require a more powerful garage door opener motor, and is going to need heavier springs and pulleys as part of the opening system.

Garage Residential Track Option

Residential track options, to be blunt, aren’t very popular as a current building style, but they are available and can be a great option for certain residential building styles. It’s a double door specially designed to allow access to either side at any time, but not to both sides of the garage at once.

Garage Commercial Track Option

Modern garage doors raise upward and fold across the garage ceiling. Traditional barn and utility building garage door designs opened sideways as sliding doors. Track option doors provide such a classic design style with a functioning garage door built to modern expectations for practical use. They can generally be the appropriate size as expected for a single car, two-car, or larger garage.
