At times, it is necessary to calculate the square yardage of a room or property to place a value on it, or to figure the proper quantity of materials or supplies that you will need to buy. When figuring square yardage, it is always best to break up the area you are measuring into a series of squares or rectangles. These smaller areas can then be measured individually, and the sum of their square yardage or square footage can be added together to get the total area.

Divide up the area you wish to measure into a series of rectangles or squares. This will make the total square yardage easier to measure.

Measure the length and width of each rectangular area you have split the region up in, and multiply the two numbers together. For example, an area with a width of 10 feet and a length of 14 feet has an area of 140 square feet.

Repeat Step 2 for each region and add them all together to get the total square footage of the area. For example, if the individual areas were 50 square feet, 100 square feet and 60 square feet, the total square footage would be 210 square feet.

Divide the total square footage by 9 to get the square yardage of the area. Using the example above, the square yardage would be 23.33 square yards. (210/9).
