How the Raised Garden Bed Calculator Works
The calculator uses standard volume and measurement formulas to determine soil and lumber requirements.
Soil Volume Formula
The amount of soil required is calculated using:
V=L×W×H
Where:
- V = Soil volume
- L = Length
- W = Width
- H = Height
Height Conversion Formula
Since height is entered in inches, it must first be converted into feet.
Height in Feet=12Height in Inches
Cubic Yard Conversion Formula
Bulk soil is commonly sold in cubic yards, so the calculator converts cubic feet into cubic yards.
Cubic Yards=27Cubic Feet
Perimeter Formula
The perimeter helps estimate the amount of lumber needed.
Perimeter=2(L+W)
Board Feet Formula
The calculator estimates lumber board feet using the bed perimeter and height.
Board Feet=Perimeter×Height
Lumber Cost Formula
If lumber price is entered, the calculator estimates the total lumber cost.
Lumber Cost=Board Feet×Price Per Board Foot
How to Use the Raised Garden Bed Calculator

Example Raised Garden Bed Calculation
Here is a practical example.
Example Dimensions
Suppose your raised garden bed measurements are:
- Length = 8 feet
- Width = 4 feet
- Height = 12 inches
- Lumber Cost = $3 per board foot
Step 1: Convert Height into Feet
1212=1 foot
Height in feet = 1 foot
Step 2: Calculate Soil Volume
8×4×1=32 ft3
Soil required = 32 cubic feet
Step 3: Convert to Cubic Yards
2732≈1.19 yd3
Soil volume = 1.19 cubic yards
Step 4: Calculate Perimeter
2(8+4)=24
Perimeter = 24 feet
Step 5: Calculate Board Feet
24×1=24
Lumber needed = 24 board feet
Step 6: Calculate Lumber Cost
24×3=72
Estimated lumber cost = $72
