Measure Your Space

Start by measuring the length, width, and depth of the area you plan to fill with the desired material. Use a tape measure or measuring wheel to get accurate measurements.

Calculate Volume

Once you have your measurements, calculate the volume of the space in cubic feet. Multiply the length by the width by the depth to find the total volume.

Convert to Cubic Yards

Most materials are sold in cubic yards, so you'll need to convert your volume from cubic feet to cubic yards. Divide the total volume by 27 (since there are 27 cubic feet in a cubic yard) to get the needed cubic yards.

  • 1 acre = 43,560 square feet
  • 1 cubic yard = 27 cubic feet
  • 1 ton = 2,000 pounds

Adjust for Compaction

Remember that some materials, like gravel and sand, may compact over time. Add 3-5% to your calculated volume to account for compaction, which is recommended.

Consider Shape and Slope

If your space is irregularly shaped or has a slope, you may need to adjust your calculations accordingly. Break the area into smaller, more manageable sections and calculate the volume for each section separately.

Square or Rectangle Spaces


Multiply the length by the width to get the square footage. Then, use the coverage chart for depth or rock specifics to get the tons or yards needed.

Triangle Spaces

Multiply the base by the height (or length times width) and divide in half for square footage. Then, use the coverage chart for depth or rock specifics to get the needed tons or yards.
