How the Raised Bed Soil Calculator Works
The calculator uses simple volume formulas to determine how much soil is needed for your raised bed.
Soil Volume Formula
The total soil volume is calculated using:
V=L×W×D
Where:
- V = Volume
- L = Length
- W = Width
- D = Depth
Depth Conversion Formula
Since depth is entered in inches, the calculator first converts inches into feet.
Depth in Feet=12Depth in Inches
Cubic Yard Conversion Formula
Garden soil is commonly sold in cubic yards. The calculator converts cubic feet into cubic yards automatically.
Cubic Yards=27Cubic Feet
Soil Bag Formula
The calculator also estimates how many 2 cubic foot soil bags are needed.
Bags Needed=2Cubic Feet
The result is rounded up to ensure enough soil is available.

Example Raised Bed Soil Calculation
Here is a practical example to understand how the calculator works.
Example Measurements
Suppose your raised bed dimensions are:
- Length = 8 feet
- Width = 4 feet
- Depth = 12 inches
Step 1: Convert Depth to Feet
1212=1 foot
Depth in feet = 1 foot
Step 2: Calculate Cubic Feet
8×4×1=32 ft3
Total soil volume = 32 cubic feet
Step 3: Convert to Cubic Yards
2732≈1.19 yd3
Soil required = 1.19 cubic yards
Step 4: Calculate Soil Bags Needed
232=16 bags
You will need approximately 16 soil bags.
