Single Car Garage Dimensions. An average single car garage will have the dimensions of 12 feet width X 22 feet length (264 square footage), but 14 feet wide is recommended for the ease of opening up your car doors. Knowing the square footage your home desires will help in determining what else can be stored in the garage with your car.
A standard double wide garage door is 16 feet wide. But you can by them in narrower sizes or up to 20 feet wide. I recommend the 18 foot width when possible. This gives a bit more room between your cars when they are parked in the garage.
