What else matters here
Four hundred and eighty square feet, and the most common two car garage built in the United States.
Twenty feet of width is the practical minimum for two cars: two mid size vehicles are about 6 feet wide each, which leaves roughly 8 feet split across three gaps, and that is enough to open a door but not enough for a person to walk between them with shopping. Twenty two by twenty four is noticeably better. Twenty four feet of depth takes a full size pickup at around 19 to 20 feet with a few feet at the end for a bench or a mower, which is what the depth is really for.
What this calculator assumes
- Length times width, times how many areas are that size. For an L shaped room, split it into two rectangles and run this twice.
- Square yards are square feet divided by nine, which is how carpet is still quoted in much of the country.

480 square feet, which is 53.33 square yards and 44.59 square meters.

How deep should a garage be?
At least 22 feet for a full size pickup, and 24 feet if you want a workbench or storage across the end wall.
