Raised garden bed calculator

How to use the calculator

1. Enter the length, width, and height of your raised garden bed in feet.
2. Enter the spacing between plants in feet. This helps calculate the usable area.
3. Click the "Calculate" button to get the results.
4. The calculator will display the volume of soil needed, the area that can be covered, and the approximate number of soil bags required.

Understanding the results

The volume of soil needed is calculated by multiplying the length, width, and height of the garden bed. This gives you the total cubic feet of soil required.

The area that can be covered is calculated by subtracting the space taken by plants from the total area of the garden bed. This helps you plan how many plants you can grow.

The number of soil bags needed is an approximation based on standard bag sizes (1.5 cubic feet each). This helps you estimate how many bags to purchase.

Example

For a garden bed that is 4 feet long, 3 feet wide, and 1 foot high with 1 foot spacing between plants:

• Volume of soil needed: 4 × 3 × 1 = 12 cubic feet
• Area that can be covered: (4 - 2) × (3 - 2) = 2 square feet
• Approximate number of bags needed: 12 / 1.5 = 8 bags
