What Is a Garden Bed Calculator?
A Garden Bed Calculator is a simple tool that helps you estimate how much soil or compost you need to fill a garden bed based on its dimensions.
It is especially useful for:
- Raised garden beds
- Planters and pots
- Vegetable gardens
- Flower beds
How Does It Work?
The calculator uses this basic formula:
Volume = Length × Width × Depth
For circular beds, it calculates volume using the radius. The result is then converted into soil bag estimates.
Why Use a Garden Bed Calculator?
- Accurate soil estimation
- Budget friendly planning
- Prevents soil wastage
- Saves time and effort
Example Calculation
If your bed is:
- 6 feet long
- 3 feet wide
- 1 foot deep
6 × 3 × 1 = 18 cubic feet
With 1.5 cu ft soil bags, you will need 12 bags.
Soil Mixing Tip
For best results in raised beds:
- 60% topsoil
- 30% compost
- 10% potting mix
