The ideal 3 car garage size, here are 2 of 3 car garage mock-ups. One is 20 feet deep by 30 feet wide, and one is 24 feet by 36 feet. Starting with the 20 by 30 garage, the door is 36 inches wide. The 2012 Ford Explorer here is 16 and a half feet long by 6 and 1/2 feet wide, and the 2013 Chevy Malibu is 16 feet long by 6 feet wide, the third vehicle that clearly does not fit is a 2013 Chevy crew cab pickup. 30 inches wide is the ideal space between two cars in the garage, allowing you to open the car door and get out. The 24 by 36 garage larger 3 garage dimensions work a lot better. With 30-inch wide line show you have room for opening doors between two cars. The ideal three-car garage dimension is at least 24 feet deep by 36 feet wide.
