Another general rule is that your driveway should be around 10 to 12 feet wide, and a few feet wider at the curves. If you have space, itâs always a good idea to provide a larger area at the top for turning around or for additional parking when needed. A 12âx18â space or larger is ideal for this.
1 15' wide is too narrow for a double wide driveway and too wide for a single car and should not be used as a driveway dimension unless there is a reason. 2  10 - 12 feet wide for a Single Car driveway. 3  14 feet wide if Surrounded by Walls. 4  18 - 20 feet wide for a Double Wide driveway.
