# How to Calculate Square Yards for Grass Sod

By Athena Hessong ; Updated September 21, 2017

Never run out of grass sod or have an unused pile left over to rot when sodding your lawn. These incidences occur when you miscalculate the number of square yards in your lawn. Some people erroneously believe that if they know their yard's square footage, they can use that number to purchase grass sod, but landscapers sell grass sod by the square yard, not the square foot. Learning how to measure your lawn and find the square yardage will ensure you purchase the correct amount of grass sod for your lawn, without any excesses or shortages.

Measure the length and width of your yard in feet.

Multiply the length by the width of your yard to determine to total area in square feet. For instance, a yard measuring 90 feet by 90 feet would be 8,100 square feet in area.

Divide the total square footage by nine to find the number of square yards in your lawn. For instance: 8,100/9 = 900 square yards.

Use your total square yards when purchasing grass sod from a landscaper or garden supply store.
