Planning a landscaping or gardening project requires precise soil calculations. Whether you are filling a garden bed, leveling a lawn, installing new sod, or preparing land for planting, knowing the correct amount of soil is essential.
Our Soil Calculator on our website helps you determine exactly how much soil you need based on your project dimensions. This eliminates guesswork, reduces waste, and helps you stay within budget.
What Is a Soil Calculator?
A Soil Calculator is a practical tool designed to compute the total soil volume required for a specific area.
It calculates soil volume using:
- Length
- Width
- Depth
The results are typically shown in:
- Cubic feet
- Cubic yards
These are the standard units used by soil suppliers.
Required Inputs
To use the Soil Calculator, you need:
- Length of the area (in feet or meters)
- Width of the area (in feet or meters)
- Desired soil depth (in inches or feet)
All measurements must use consistent units for accurate results.
Expected Outputs
After entering the values, the calculator provides:
- Total soil volume in cubic feet
- Equivalent volume in cubic yards
This allows you to place accurate orders with soil suppliers.
Calculation Logic and Formula
Step 1: Calculate Surface Area
Area = Length × Width
Step 2: Convert Depth to Feet (if necessary)
Depth (feet) = Depth (inches) ÷ 12
Step 3: Calculate Volume
Volume (cubic feet) = Area × Depth
Step 4: Convert to Cubic Yards
Cubic Yards = Cubic Feet ÷ 27
Since 1 cubic yard equals 27 cubic feet, dividing by 27 converts the result.
How to Use the Soil Calculator
Step 1: Measure Your Area
Use a measuring tape to determine the length and width.
Step 2: Determine Soil Depth
Decide how thick the soil layer should be.
Step 3: Enter the Values
Input your measurements into the calculator.
Step 4: Get Instant Results
The calculator immediately shows the required soil volume.
Practical Example
Imagine you want to fill a backyard section with:
- Length: 20 feet
- Width: 15 feet
- Depth: 4 inches
Convert depth:
4 inches ÷ 12 = 0.33 feet
Calculate area:
20 × 15 = 300 square feet
Calculate volume:
300 × 0.33 = 99 cubic feet
Convert to cubic yards:
99 ÷ 27 = 3.67 cubic yards
You would need approximately 3.7 cubic yards of soil.
