Every material calculator on the site starts here, which is why this one also gives square yards and square meters. Odd shapes get broken into rectangles and added on, because a rectangle is the only shape a tape measure is honest about.

What else matters here

Five hundred and seventy six square feet is the standard detached two car garage, and unlike the 20 by 20 it is the size that actually works: two vehicles, both doors open, and a bench along one wall.

The number is convenient in other ways too. Twenty four feet is exactly two twelve foot sheets, three eight foot studs laid end to end, or four six foot post bays. Framing, sheathing and roofing all land on whole units, which is part of why this footprint is so common in kit buildings.

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.

How many square feet is a 24x24 garage?

576 square feet, which is 64 square yards and 53.51 square meters.

How much concrete for a 24x24 garage slab?

About 11.7 cubic yards at six inches with waste, which is what a floor carrying two vehicles should be. There is a dedicated page for that slab on this site.
