A standard four-car garage is designed to provide sufficient space for parking and storage while accommodating the dimensions of typical cars. In the metric system, a four-car garage typically has a width of 12.19 meters, a depth of 6.10 meters, and a height ranging from 2.13 to 2.74 meters. These dimensions ensure ample room for comfortably parking four cars side by side.

The width of 12.19 meters allows for parallel parking of four standard-sized cars. This dimension takes into account the average width of a car, which is approximately 1.83 meters. With this width, there is enough space for each car to be parked comfortably without any risk of collisions or difficulty in opening car doors.

The depth of 6.10 meters provides adequate space for the length of each car. Considering that the average length of a standard car is around 4.88 meters, this depth allows for each car to be parked with enough room to spare. This extra space not only facilitates easy entry and exit but also provides some additional storage capacity.

The height of the garage is a critical dimension, ensuring that there is sufficient clearance for different types of vehicles. The recommended height ranges from 2.13 to 2.74 meters. This accommodates the height of standard cars, as well as taller vehicles like SUVs and trucks. A minimum height of 2.13 meters is recommended, but having a taller garage (2.74 meters or more) is ideal for versatility and accommodating larger vehicles.

For ease of access, a four-car garage typically features four garage doors. Each door is typically 3.66 meters wide and 2.44 meters tall. This allows each car to have its dedicated entrance and exit, facilitating convenient parking and retrieval.

Design Considerations for a Four-Car Garage

When embarking on the design of your four-car garage, several crucial considerations can significantly impact its functionality and aesthetics:

Door Placement

  • Cost-Effective Design: Placing garage doors on the side rather than the front (gable) end can be more cost-effective, resulting in a shorter and less expensive roof structure.

Windows and Access Doors:

  • Natural Light: Strategically placing windows ensures sufficient natural light, creating a more pleasant environment.
  • Convenient Entry Points: Consider the placement of access doors for convenient entry and exit, enhancing the overall usability of the space.

Exploring Oversized Four-Car Garages

For those seeking even more space or planning to store larger vehicles, opting for an oversized four-car garage brings several benefits:


  • At least 44 feet wide, 24 feet deep, and 8 feet tall.


  • Larger Vehicles: Accommodate larger vehicles, SUVs, or trucks comfortably.
  • Additional Space: Allows for storage shelves, workstations, or a dedicated area for hobbies and crafts.
