Planning a landscaping project? Use Leonberg’s free Materials Calculator to estimate how many cubic yards of mulch, topsoil, compost, decorative stone, gravel, or sand you’ll need.
Simply enter the length and width of your project area in feet, along with your desired material depth in inches. Our calculator will estimate the cubic yards required, helping you plan your purchase and delivery.
How to Calculate Your Materials
Rectangular or square areas: Measure the length and width of the area in feet and enter your desired material depth in inches.
Circular areas: Measure the radius (half the diameter) in feet. Calculate the area using 3.14 × radius × radius, then divide that area by the material depth conversion to estimate cubic yards.
Irregularly shaped areas: Divide the space into smaller rectangular sections, calculate each area separately, and add the quantities together.
Calculator results are estimates. Actual material requirements may vary based on application depth, surface conditions, and settling.
