Volume Breakdown

Ordering bulk material?

Enter the surface area and desired thickness to find out how much soil, mulch, or gravel you need to order.

Overview

In most construction and landscaping projects, materials like concrete, gravel, and mulch are sold by volume (cubic yards or cubic meters). Since project areas are usually measured in square feet or meters, this converter bridges the gap, allowing you to accurately estimate your load requirements.

💡

Pro Tips

Materials like mulch and screen soil will settle over time; order 10-15% more than the calculated volume to reach your target depth.
For gravel, if you plan to compact it with a plate compactor, you may need up to 20% extra material.
One cubic yard covers 324 square feet at 1 inch deep.

Fun Facts

"One cubic yard is a cube that is 3 feet long, 3 feet wide, and 3 feet deep."
"Most standard full-size pickup trucks can carry about 1 to 1.5 cubic yards (0.75-1.1 cubic meters) of light material like mulch."
"Professional concrete mixer trucks typically hold between 9 and 11 cubic yards (7 to 8.5 cubic meters) of wet concrete."

Formula: Yards³ = [Area (ft²) × (Depth (in) / 12)] / 27
