Before installing plants, sod grass, mulch or other landscape materials you might need to determine the total square footage of the space you intend to fill. Here are simply formulas for determining the total square feet in a given area.

Calculating Total Square Feet in a Square or Rectangular Area

To determine total square feet in a square or rectangular space, simply multiply the length of the area by the width of the area. For example, if the length of a square area is 50 feet and the width of the area is 50 feet the equation would look like this:

50' x 50' = 2,500 Total Square Feet

Here is the equation for a rectangular area measuring 100 feet long by 25 feet wide:

100' x 25' = 2,500 Total Square Feet

You can also plug measurements into this Square Footage Calculator.

Calculating Total Square Feet in a Circular Area

The formula for determining the total square feet in a circular area is: A = Pi x R2 (Area = Pi x R-squared). This formula may mean nothing to you so here's a explanation:

To determine the total square footage in a circular area you will first need to determine the radius of the circle. The radius of the circle is the distance from the center of the circle to the outside (perimeter) of the circle, as shown in the illustration below. Once you know the length of the radius of a circle multiply the radius by 2. Then multiply this figure by Pi, which is 3.1416, to determine total square feet in the circular area.

Here is the equation for a circle that has a radius of 20 feet.

3.1416 x 20' x 20' = 1256 Total Square Feet

Here is the equation for a circle that has a radius of 5 feet:

3.1416 x 5' x 5' = 78.54 Total Square Feet
