For raised beds, you typically need 6-12 inches of soil depth. Use our calculator by entering your bed's length, width, and desired depth to get the exact cubic yards needed.
A cubic yard equals 27 cubic feet, so you'd need about 13.5 bags of 2 cubic foot topsoil bags to equal one cubic yard of soil.
Ground cover and annual flowers need 2-4 inches, vegetables require 6-8 inches, and deep-rooted plants like tomatoes need 10-12 inches of quality soil.
Select 'Circle' in the shape dropdown, then enter the diameter as the length. The calculator will automatically compute the area using the circle formula.
