Top Soil Size Formula:
From: | To: |
Top soil volume refers to the amount of topsoil needed for a gardening or landscaping project, calculated by multiplying the area to be covered by the desired depth of topsoil.
The calculator uses the simple formula:
Where:
Explanation: This calculation gives you the volume of topsoil required in cubic feet.
Details: Accurate topsoil calculation ensures you purchase the right amount of soil for your project, avoiding both shortages and wasteful excess.
Tips: Measure your area accurately in square feet and decide on the appropriate depth for your plants (typically 6-12 inches for gardens). Convert inches to feet (divide by 12) before entering.
Q1: How deep should topsoil be?
A: For lawns, 4-6 inches is typical. For gardens, 6-12 inches is recommended depending on plants.
Q2: How do I convert cubic feet to cubic yards?
A: Divide cubic feet by 27 (since 1 cubic yard = 27 cubic feet).
Q3: Should I account for compaction?
A: Yes, consider adding 10-15% extra to account for settling and compaction over time.
Q4: How do I measure irregular areas?
A: Break the area into simple shapes (rectangles, circles), calculate each separately, then sum the areas.
Q5: What's the difference between topsoil and garden soil?
A: Topsoil is the upper layer of natural soil, while garden soil is often enriched with compost and amendments.
