Calculating Square Footage

Step One: Measure

Use a tape measure to determine the width and the length of your rectangular area. Make sure you’re measuring in feet!

Step Two: Write

Be sure to write down each measurement as you go along so you don’t forget them.

Step Three: Multiply

For a rectangular space, multiply the length by the width. Remember: length x width = area. This will yield the square footage.

Step Four: Different Shapes

To calculate the square footage of a triangular area, measure the base and the height, multiply those numbers, then divide it by two. Base x height / 2 = area

For the square footage of a circular area, measure the middle of the circle, or the diameter, then use this formula: pi x half the diameter squared, or π x (d/2)2
