How to Use the Soil Calculator
Our soil calculator helps you estimate the exact amount of soil needed for your garden beds. Simply follow these steps:
- Select the shape of your garden bed: rectangle, circle, ring (for circular paths), or irregular (combination of rectangles)
- Enter your measurements in feet. For rectangles, provide length and width. For circles, enter the radius. For rings, enter both outer and inner radii.
- Specify the soil depth. Common depths are 2-3 inches (0.17-0.25 feet) for most applications
- Optionally, enter the price per bag (typically $5-8 for 2 cubic foot bags) to calculate total cost
The calculator instantly shows you the area in square feet, volume in cubic yards, number of bags needed (based on 2 cubic feet per bag), and total cost. This helps you purchase exactly the right amount of soil, minimizing waste and saving money.
Frequently Asked Questions
How deep should soil be?
For most garden beds, a soil depth of 2-3 inches (0.17-0.25 feet) is recommended. Too thin won't suppress weeds effectively, while too thick can prevent water and air from reaching plant roots.
How much area does one bag of soil cover?
A standard 2 cubic foot bag of soil covers approximately 6 square feet at 4 inches deep, 8 square feet at 3 inches deep, or 12 square feet at 2 inches deep.
What's the best time to apply soil?
Early spring (after soil warms) and fall (before ground freezes) are ideal times for soiling. Avoid soiling frozen ground or during extreme heat.
