There isn’t a single standard size for double-car garage doors. That said, most doors will range in size from 12 to 18 feet wide and six to eight feet tall, generally correlating with the size of the garage. If you don’t like your current doors, you can always change them!
The width and height of garage doors are aesthetic issues for most people because even a small garage door will fit a car or two. However, homeowners with large assets like oversized vehicles or boats may need to invest in irregularly sized doors. Unfortunately, changing out your garage doors can cost a pretty penny. Take some time to find an affordable contractor before you get started.
