Material Calculator


Please use our volume calculator to estimate the volume of material that your job requires. The average depth of material normally ranges between two and three inches, depending on the product you select and your surface condition.




Volume Calculator

Enter the approximate length and width of the shape you want to cover, then the desired depth (standard depth for mulch is 3"), then click Calculate.
The calculator will estimate the approximate cubic yards of material you'll need. When entering your numbers, please use decimals. It is also a good idea to add 10% extra to account for settling.

Note: Coverage will vary slightly depending on the product. To calculate the amount needed for products with coverage other than 120 sq.ft./ton, use this formula: length x width / coverage.
