Cubic Yard Calculator
Calculate the volume in cubic yards for your construction, landscaping, or home improvement project. Perfect for concrete, soil, gravel, mulch, sand, and more. Get accurate estimates, reduce waste, and plan your material orders with confidence.
What is a Cubic Yard?
A cubic yard is a unit of volume commonly used in the United States for measuring large quantities of materials such as concrete, soil, gravel, mulch, sand, and debris. One cubic yard is equal to 27 cubic feet (3 feet × 3 feet × 3 feet) or approximately 0.7646 cubic meters. Understanding cubic yards is essential for anyone involved in construction, landscaping, gardening, or home improvement projects, as it helps ensure you order the right amount of material and avoid costly shortages or excess.
Why Use a Cubic Yard Calculator?
Manual calculations can be error-prone, especially when dealing with irregular shapes, multiple layers, or waste factors. A cubic yard calculator streamlines the process, providing quick, accurate results and helping you:
- Estimate material needs for concrete, soil, gravel, mulch, sand, and more
- Reduce waste and save money by ordering the right amount
- Plan deliveries and storage efficiently
- Compare costs between suppliers
- Ensure compliance with project specifications
Types of Projects That Use Cubic Yards
- Concrete: Slabs, footings, foundations, driveways, sidewalks, patios
- Landscaping: Soil, compost, mulch, decorative rock, fill dirt
- Gravel: Driveways, walkways, drainage, base layers
- Sand: Playgrounds, sports fields, paver bases
- Debris Removal: Construction waste, demolition debris, yard cleanup
- Gardening: Raised beds, planters, topsoil
How to Use the Cubic Yard Calculator
- Measure the length and width of the area in feet.
- Measure the depth in inches (for most projects, 2-12 inches is typical).
- Enter your measurements into the calculator fields above.
- Adjust the waste factor if needed (default is 10% to account for spillage, compaction, and irregularities).
- Click "Calculate" to see the results in cubic yards, cubic feet, cubic meters, and with waste included.
Common Specifications and Conversion Factors
- 1 cubic yard = 27 cubic feet
- 1 cubic yard = 0.7646 cubic meters
- 1 cubic foot = 0.03704 cubic yards
- 1 cubic meter = 1.30795 cubic yards
- 1 foot = 12 inches
Calculation Formulas
- Volume (cubic feet): Length (ft) × Width (ft) × Depth (in ÷ 12)
- Volume (cubic yards): Volume (cubic feet) ÷ 27
- Volume with Waste: Volume (cubic yards) × (1 + Waste Factor)
- Volume (cubic meters): Volume (cubic yards) × 0.7646
For irregular shapes, break the area into rectangles or circles, calculate each separately, and sum the results.
Material Considerations and Tips
- Compaction: Some materials (like soil or gravel) compact after placement. Add extra to account for this.
- Moisture Content: Wet materials may weigh more and take up less space than dry materials.
- Delivery: Order a little extra to avoid running short, especially for concrete pours.
- Supplier Rounding: Many suppliers round up to the nearest 0.25 or 0.5 cubic yard.
- Access: Ensure delivery trucks can access your site and have space to unload.

- Volume with Waste: 5.09 cubic yards
Frequently Asked Questions
What is a cubic yard?
A cubic yard is a unit of volume equal to 27 cubic feet. It is commonly used in the U.S. for measuring bulk materials in construction and landscaping.
Why include a waste factor?
Waste factors account for spillage, compaction, and irregularities. They help ensure you have enough material to finish your project without running short.
How do I measure the area?
Measure the length and width in feet. For irregular shapes, break the area into rectangles or circles and sum the results.
What if my depth is in feet?
If your depth is in feet, multiply by 12 to convert to inches before entering it in the calculator.
How accurate are the calculations?
The calculator provides mathematically precise results, but actual needs may vary due to compaction, moisture, and site conditions. Always order a little extra.
How do I convert between cubic yards and other units?
Use these conversions:
- 1 cubic yard = 27 cubic feet
- 1 cubic yard = 0.7646 cubic meters
- 1 cubic meter = 1.30795 cubic yards
What are common mistakes to avoid?
Common mistakes include:
- Incorrect area or depth measurements
- Forgetting to include a waste factor
- Not accounting for compaction or settling
- Ordering too little or too much material
How do I ensure accurate measurements?
Use a reliable tape measure or laser measure, double-check all dimensions, and keep detailed records. For large projects, consult with a professional.
What about safety and compliance?
Follow local building codes, use proper safety gear, and ensure safe access for delivery vehicles. Train workers on safe handling and placement of materials.
How do I plan for delivery and storage?
Schedule deliveries to minimize delays, ensure site access, and arrange for covered storage if needed. Coordinate with suppliers and contractors.
What are the cost implications?
Consider material costs per cubic yard, delivery fees, labor, equipment, and potential overages. Compare quotes from multiple suppliers.
How do I handle large projects?
Break the project into sections, order materials in phases, and coordinate with multiple suppliers. Plan for storage and logistics.
What about environmental considerations?
Choose sustainable materials, recycle waste, and comply with environmental regulations. Consider the long-term impact of your project.
Safety, Compliance, and Environmental Tips
- Wear gloves, boots, and eye protection when handling bulk materials
- Follow all local codes and regulations
- Keep work areas clear and organized
- Dispose of waste responsibly
