Cubic Yards Calculator

Determine exactly how much bulk material you need to order. This tool calculates the yardage for any shape and even estimates your total project cost.

Basic Method: 1. Find Area in square feet. 2. Volume (ft³) = Area × (Depth in inches ÷ 12) 3. Cubic Yards = Volume (ft³) ÷ 27
A 10ft x 20ft flower bed at 3 inches deep: Area = 200 sq ft. Volume = 200 × 0.25 = 50 cu ft. Cubic Yards = 50 ÷ 27 ≈ 1.85.

How do I calculate cubic yards?

To calculate cubic yards, find the volume of your area in cubic feet (Length × Width × Depth) and then divide that number by 27. Formula: Cubic Yards = Volume in Cubic Feet / 27.

How deep should mulch or gravel be?

For garden mulch, a depth of 3 inches is standard. For gravel driveways, 4 inches is typical. For walkways, 2-3 inches usually suffices.

How many bags are in a cubic yard?

Standard bags of mulch or soil are usually 2 cubic feet. Since one cubic yard is 27 cubic feet, you would need 13.5 bags to equal one cubic yard.

Why divide by 27?

A yard is 3 feet long. A cubic yard is a cube that is 3ft x 3ft x 3ft, which equals 27 cubic feet. Dividing your cubic foot total by 27 converts the measurement to yards.
