For a single-car driveway, the typical length is 18 to 20 feet, and the typical width is 10 to 12 feet. The width and length of a two-car driveway, when the vehicles are parked side-by-side, should be 18 to 20 feet.
A larger driveway enables people to exit the car without stepping on the lawn or flowerbeds, with a minimum width of 10 feet. Despite the fact that these measurements are typical, more room is advised if other structures, such as a retaining wall encircling the property, are close to the driveway.
For each additional vehicle that a homeowner must park behind the other, they need an additional 18 to 20 feet of space.
