How It Works

This calculator finds the total volume of your garden bed. It then uses the provided density (average dry topsoil is ~80 lbs/ft³ or 1281 kg/m³) to convert that volume into weight. If you provide bag details, it will estimate the number of bags and total cost.

Understanding Top Soil Calculations

Topsoil is the upper, outermost layer of soil, usually the top 2 to 8 inches. It has the highest concentration of organic matter and microorganisms and is where most of the Earth's biological soil activity occurs.

Settling is Real

Like gravel, soil contains a lot of air when it's first delivered (fluffed up). Once you spread it and water it, it will settle.

Settling Factor: Add 15-20% to your calculated volume.
1 Cubic Yard covers ~100 sq ft at 3 inches deep.
