Planning a garden, landscaping project, or yard improvement often requires knowing how much dirt you’ll need. Guesswork can lead to buying too little (causing project delays) or too much (wasting money). That’s where a Yard Dirt Calculator becomes a lifesaver.
This simple yet powerful tool helps you calculate the cubic feet and cubic yards of soil or dirt required for any space based on length, width, and depth. Whether you’re filling a raised bed, preparing a lawn, or starting a large landscaping job, our calculator gives you accurate results instantly.
Yard Dirt Calculator
What is a Yard Dirt Calculator?
A Yard Dirt Calculator is an online tool designed to measure the volume of dirt, soil, gravel, mulch, or any fill material required for a given space. It uses simple math formulas to convert length, width, and depth into:
- Cubic Feet – The total volume in feet.
- Cubic Yards – A standard measurement for bulk material (1 cubic yard = 27 cubic feet).
This calculator eliminates manual calculations, making it quick and easy to order the right amount of material for your project.
Why Do You Need a Dirt Calculator?
- Save Money – Prevents overspending on unnecessary dirt or fill.
- Avoid Shortages – Ensures you have enough material to complete the job.
- Save Time – Instant results without manual math.
- Accuracy – Helps contractors, landscapers, and homeowners make precise orders.
- Versatility – Works for soil, sand, gravel, compost, mulch, and more.
How to Use the Yard Dirt Calculator
Using this tool is extremely simple. Just follow these steps:
- Enter the Length (in feet):
Measure the longest side of the area you want to fill. - Enter the Width (in feet):
Measure the shorter side of the area. - Enter the Depth (in inches):
Input how deep you want the soil or dirt to be. Since most people measure depth in inches, the calculator automatically converts it into feet. - Click "Calculate":
The tool instantly shows you:- Cubic Feet
- Cubic Yards

Example Calculations
Let’s look at some real-life examples of how you might use the Yard Dirt Calculator:
Example 1: Garden Bed
- Length: 10 feet
- Width: 4 feet
- Depth: 12 inches (1 foot)
Result:
- Cubic Feet = 10 × 4 × 1 = 40 cubic feet
- Cubic Yards = 40 ÷ 27 = 1.48 cubic yards
👉 You’ll need about 1.5 cubic yards of soil.
Example 2: Lawn Topsoil
- Length: 30 feet
- Width: 20 feet
- Depth: 4 inches (0.33 feet)
Result:
- Cubic Feet = 30 × 20 × 0.33 = 198 cubic feet
- Cubic Yards = 198 ÷ 27 = 7.33 cubic yards
👉 You’ll need around 7.5 cubic yards of topsoil.
Example 3: Playground Sand Area
- Length: 15 feet
- Width: 15 feet
- Depth: 6 inches (0.5 feet)
Result:
- Cubic Feet = 15 × 15 × 0.5 = 112.5 cubic feet
- Cubic Yards = 112.5 ÷ 27 = 4.16 cubic yards
👉 You’ll need about 4.2 cubic yards of sand.
Tips for Accurate Results
- Always measure length and width inside the area where the material will go.
- Convert inches into decimals (e.g., 6 inches = 0.5 feet, 4 inches = 0.33 feet).
- Round up slightly to avoid running short on material.
- Consider soil compaction – dirt settles after spreading, so ordering 5–10% extra is wise.
- If your project area is irregular (like circular or triangular), break it into smaller sections, calculate separately, and add results together.
Who Can Use This Tool?
- Homeowners – for gardens, flower beds, and lawns.
- Landscapers – for larger yards, pathways, and outdoor projects.
- Contractors – for construction backfill and leveling.
- DIY Enthusiasts – for playgrounds, patios, or small projects.
20 Frequently Asked Questions (FAQs)
Q1: What does a Yard Dirt Calculator measure?
It measures volume in cubic feet and cubic yards based on area and depth.
Q2: How many cubic feet are in one cubic yard?
There are 27 cubic feet in one cubic yard.
Q3: Can I use this calculator for gravel or sand?
Yes, it works for soil, gravel, sand, compost, mulch, and other bulk materials.
Q4: How do I convert inches to feet for depth?
Divide the depth in inches by 12. For example, 6 inches = 0.5 feet.
Q5: Why do landscapers use cubic yards instead of cubic feet?
Cubic yards are the standard unit for bulk material deliveries.
Q6: How accurate is this calculator?
It provides exact math results, but you may need to order slightly more due to compaction or spillage.
Q7: Do I need to measure in feet only?
Yes, for length and width use feet. The calculator automatically converts inches for depth.
Q8: What if my area is round or irregular shaped?
Divide it into rectangles, calculate each, and then add the totals.
Q9: Can I use this calculator for raised garden beds?
Yes, it’s perfect for raised beds. Just enter length, width, and soil depth.
Q10: Is soil sold by cubic feet or cubic yards?
Bulk soil is usually sold by the cubic yard, while bagged soil is often measured in cubic feet.
Q11: How many bags of soil equal one cubic yard?
A 1.5-cubic-foot bag – You’ll need about 18 bags per cubic yard.
Q12: How do I know how much topsoil I need for my lawn?
Measure your lawn area and depth (usually 4–6 inches) and use the calculator.
Q13: What if I only know the area in square feet?
Multiply the square feet by depth (in feet) to get cubic feet, then divide by 27.
Q14: Can I calculate mulch with this tool?
Yes, mulch volume works the same way as dirt or soil.
Q15: How deep should topsoil be for grass?
A depth of 4–6 inches is recommended.
Q16: Do I need to round results?
Yes, round up to ensure you have enough material.
Q17: What’s the difference between cubic feet and square feet?
Square feet measure area (2D), while cubic feet measure volume (3D).
Q18: Will soil settle after filling?
Yes, expect about 5–10% compaction. Order extra to account for this.
Q19: Can contractors rely on this calculator?
Yes, it’s widely used for quick and accurate project estimates.
Q20: Is the calculator free to use?
Yes, our Yard Dirt Calculator is 100% free and available online.
Conclusion
The Yard Dirt Calculator is an essential tool for anyone working with soil, dirt, mulch, or fill material. By entering just three measurements—length, width, and depth—you’ll instantly know how much material to order in both cubic feet and cubic yards.
Whether you’re a homeowner planting a garden, a landscaper preparing a yard, or a contractor handling large projects, this tool saves time, money, and frustration. Try it now and make your next project hassle-free!
