Volume Calculation:
From: | To: |
The Soil Volume Calculator helps gardeners and landscapers determine how much soil is needed to fill garden beds or other planting areas. It calculates the volume based on the dimensions of the space.
The calculator uses the basic volume equation:
Where:
Explanation: The equation calculates the total volume in cubic feet, then converts it to cubic yards (since soil is often sold by the cubic yard).
Details: Proper soil calculation ensures you purchase the right amount of soil - not too little that leaves your garden incomplete, nor too much that wastes money and resources.
Tips: Measure your garden bed's length and width in feet. Determine how deep you want the soil to be (typically 6-12 inches for most plants, which is 0.5-1 foot).
Q1: How do I measure irregularly shaped beds?
A: For irregular shapes, divide into rectangles, calculate each separately, then sum the volumes.
Q2: Should I account for soil compaction?
A: Yes, consider adding 10-15% more soil to account for settling over time.
Q3: What if my depth is in inches?
A: Convert inches to feet by dividing by 12 (e.g., 6 inches = 0.5 feet).
Q4: How many bags of soil is this?
A: Bag sizes vary, but common sizes are 1 cubic foot or 2 cubic feet. Divide total cubic feet by bag size.
Q5: Does this work for raised beds?
A: Yes, the calculation works the same for raised garden beds.
