One-thousand square feet is a size that describes the area of a surface, such as a floor or parcel of land. An area that occupies 1,000 square feet can come in a variety of shapes.

The square footage of an area is calculated in a variety of ways, based upon its shape. The square footage of a square or rectangular space can be determined by multiplying the width of the space by the length of the space.

For example, a room that is 50 feet long and 20 feet wide could occupy 1,000 square feet. A triangular room that contains one right angle and has a length of 40 feet and a width of 50 feet could also occupy 1,000 square feet.
