Two-car garages are available in a variety of sizes and can be either attached to a home or freestanding. In addition to protecting vehicles and providing storage space, a two-car garage can increase a home's property value.
The smallest standard width of a two-car garage is 610 cm (20 feet), which will provide just enough space to fit two cars side by side. A 690 cm (22 foot) garage will provide a small amount of additional space for storage.
The minimum standard depth of a two-car garage is 610 cm (20 feet). Increasing the garage depth to 850 cm (28 feet) will provide enough space for longer vehicles or additional equipment such as a work bench or shelving.
The standard height of a two-car garage is 240 cm (8 feet).
The standard height for a two-car garage door is between seven and nine feet. The standard door width is between 360 and 540 cm (12 and 18 feet).
Attached vs. Free-Standing Garages
The size of an attached two-car garage is typically based on the size of the house and cannot be altered by the homeowner. If building a free-standing garage, the homeowner can determine the size based on vehicle dimensions and storage needs.
