Two Car Garage Dimensions

A two car garage is at least 20 x 20 ft (400 sq ft), but that only fits two small cars with the doors barely opening. 24 x 24 ft (576 sq ft) is the size most designers recommend, and 24 x 30 ft or more leaves room for a workbench, storage or a full-size truck.

Two car garage door sizes

One double door: 16 ft wide x 7 ft tall is standard. 16 x 8 ft fits lifted trucks and roof racks, and is common on custom builds.
Two single doors: 8 x 7 ft or 9 x 7 ft each, with a post between. 9 ft doors are easier to drive through with wide vehicles.
Leave about 2 ft of wall beside the door on each side for the door track and shelving.

How much space a car really needs

Most cars are 6 to 7 ft wide without mirrors and 15 to 20 ft long. Add about 2 1/2 to 3 ft beside each car to open doors and get out, and 3 ft in front to walk past. Two midsize SUVs (about 6.5 ft wide each) need roughly 6.5 + 6.5 + 3 x 3 = 22 ft of width for a comfortable fit, which is why 24 ft wide garages feel right.

A crew-cab pickup is about 19 to 20 ft long, so it needs a garage at least 24 ft deep, and 26 ft or more if there is a workbench at the front.

Ceiling height

A 7 ft door works with an 8 ft ceiling. An 8 ft door needs about 9 to 10 ft of ceiling for the opener and track. Storage racks hung from the ceiling need more again, and a car lift usually needs about 12 ft. Check the door and lift makers' specs before you set the wall height.
