How Do I Calculate How Much Topsoil I Need?

To calculate how much topsoil you need using your specific project requirements and our topsoil calculator, follow these steps tailored to your needs:

  • Top Dressing Lawn: If you’re looking to top dress your existing lawn, you need to calculate a 1-inch depth. Simply enter the length and width of the lawn area into the calculator, then input 1 inch as the depth.
  • Vegetable Garden: For a vegetable garden that requires a healthier amount of soil, enter a depth between 8 inches to 12 inches, depending on your preference and the specific needs of your garden plants.
  • New Home Seed Lawn: If you’re seeding a new lawn at home, set the depth in the calculator between 4 inches and 6 inches. This ensures the seeds have adequate coverage to germinate effectively.
  • New Home Sodded Lawn: For laying new sod, a depth between 3 inches and 5 inches provides solid ground for the sod to establish its roots. Enter this range into the calculator based on the sod specifications or your landscaper’s recommendations.
  • Raised Planting Beds: Raised beds for flowers or vegetables often require deeper soil for root growth, drainage, and nutrient availability. Calculate a depth between 12 inches and 18 inches for the healthiest raised planting environment.

Once you have measured the length and width of the area and decided on the appropriate depth for your specific project, input these values into the respective fields in our topsoil calculator. The calculator will then compute and provide you with the cubic feet or cubic yards of topsoil required. If you are purchasing topsoil in bags, select the bag size in the calculator to determine the number of bags needed for your project.
