A Cubic Yard Calculator estimates the volume of material needed for landscaping, construction, or excavation projects. One cubic yard equals 27 cubic feet—roughly the size of a standard washing machine. This measurement is the industry standard for ordering bulk materials like mulch, topsoil, gravel, concrete, and fill dirt.
Whether you’re planning a garden bed, pouring a concrete patio, or leveling a backyard, knowing your cubic yardage prevents overordering (wasting money) or underordering (delaying your project). This cubic yard calculator accepts length, width, and depth in feet, yards, inches, meters, or centimeters—no manual conversion needed. Enter your dimensions, add an optional price per cubic yard, select your currency, and get instant volume and cost estimates. Powered by Toolraxy, all calculations happen locally in your browser. Your measurements never leave your device.

The cubic yard calculation follows standard construction and landscaping volume formulas used across North America and globally.
Cubic Feet = Length (ft) × Width (ft) × Depth (ft) Cubic Yards = Cubic Feet ÷ 27 Total Cost = Cubic Yards × Price per cubic yard
All dimensions convert to feet before calculation:
Length and Width conversions to feet:
Feet (ft) → Multiply by 1
Yards (yd) → Multiply by 3
Inches (in) → Divide by 12
Meters (m) → Multiply by 3.28084
Centimeters (cm) → Divide by 30.48
Depth/Height conversions to feet:
Inches (in) → Divide by 12
Feet (ft) → Multiply by 1
Yards (yd) → Multiply by 3
Centimeters (cm) → Divide by 30.48
Meters (m) → Multiply by 3.28084
Any dimension of zero or below shows “—” for all results
Negative numbers are treated as zero
Price of zero hides the cost row entirely
All volume results round to 2 decimal places
Cubic yards display with “yd³” suffix
Cubic feet display with “ft³” suffix
Mixed units (length in feet, width in inches, depth in centimeters)
Very shallow depths (0.1 inches for seed cover or sand)
Large areas (converts and displays with comma separators)
Price per cubic yard of 0.00 → cost section hidden
Non-numeric inputs → treated as zero
Real-world scenario: You’re landscaping a backyard and need to order mulch for a flower bed.
Length: 20 feet
Width: 8 feet
Depth: 3 inches (recommended mulch depth)
Price per cubic yard: $45.00
Currency: USD
Step 1: Convert all dimensions to feet
Length: 20 ft (already in feet)
Width: 8 ft (already in feet)
Depth: 3 inches ÷ 12 = 0.25 feet
Step 2: Calculate cubic feet
Length × Width × Depth = 20 × 8 × 0.25 = 40 cubic feet
Step 3: Convert to cubic yards
Cubic Feet ÷ 27 = 40 ÷ 27 = 1.48 cubic yards
Step 4: Calculate total cost
Cubic Yards × Price per yard = 1.48 × $45.00 = $66.60
You need 1.48 cubic yards of mulch costing $66.60. In practical terms, order 1.5 cubic yards (most landscape suppliers sell in 0.5 yard increments). At 1.5 yards, your cost becomes $67.50, and you’ll have a small amount leftover for future touch-ups.
Takeaway: Always calculate before ordering bulk materials. This cubic yard calculator saved you from guessing—1.5 yards is the right order, not 2 yards (wasting $22.50) or 1 yard (coming up short by 0.5 yards).
A cubic yard is a unit of volume measuring 3 feet long, 3 feet wide, and 3 feet high—27 cubic feet total. Think of a standard garden wheelbarrow; it takes about 9 to 14 wheelbarrows to move 1 cubic yard of material, depending on wheelbarrow size.
This measurement matters because bulk landscaping and construction materials are sold by the cubic yard. Mulch, topsoil, compost, sand, gravel, crushed stone, concrete, and fill dirt all use cubic yards as their standard pricing unit. When a supplier quotes $45 per yard, they mean per cubic yard. Understanding cubic yards helps you compare prices accurately across different suppliers and prevents costly ordering mistakes.
Manual calculation follows three steps: measure in feet, multiply for cubic feet, divide by 27.
Example: A driveway needs gravel that’s 30 feet long, 10 feet wide, and 0.33 feet deep (4 inches).
Cubic feet = 30 × 10 × 0.33 = 99 cubic feet
Cubic yards = 99 ÷ 27 = 3.67 cubic yards
If your measurements are in different units, convert everything to feet first. A common mistake is mixing inches and feet without converting—always convert depth from inches to feet by dividing by 12 before multiplying.
There’s no universal “good” cubic yard value—it depends entirely on your project scale. A small garden bed might need 0.5 cubic yards of compost. A 10×10 patio requiring 4 inches of gravel base needs about 1.23 cubic yards. A full driveway replacement could require 10–20 cubic yards of crushed stone. An entire house foundation might need 50+ cubic yards of concrete.
What matters is accuracy relative to your project dimensions. Measure carefully, calculate precisely, then add 10–15% extra for settling, compaction, and irregular areas. Landscape suppliers recommend ordering slightly more than calculated—it’s cheaper to have leftover material than to pay a second delivery fee.
Several variables influence your cubic yard total:
Area shape complexity: Rectangular areas calculate directly. Circular or irregular shapes require different formulas (π × radius² for circles) or breaking into smaller rectangles.
Depth consistency: Uneven ground requires average depth measurements. Take 5–10 depth readings across the area and average them.
Material compaction: Some materials like gravel and crushed stone settle and compact. Order 10–15% extra for compacting materials.
Unit selection: Mixing feet and inches without conversion is the most common error. Always standardize to feet before calculating.
Sloped surfaces: For sloped areas, measure the horizontal projection, not the slope distance. The volume formula uses horizontal length and width.
Moisture content: Wet materials weigh more but don’t change volume. Cubic yard measures volume, not weight. For weight concerns, ask suppliers for material density (pounds per cubic yard).
Too high: Check that your depth isn’t in feet when it should be in inches. 0.5 feet vs 0.5 inches creates a 12× difference. Also verify you used cubic yards (divide by 27) not cubic feet.
Too low: Confirm you divided by 27. Some beginners stop at cubic feet, thinking that’s cubic yards. For example, 54 cubic feet ÷ 27 = 2 cubic yards, not 54.
Other causes: Mixed units (length in meters but width in feet without conversion), decimal points entered incorrectly (0.5 vs 5), or forgetting that depth uses the same unit conversion as length and width.
Use a cubic yard calculator in these situations:
Before ordering landscape materials – Mulch, topsoil, compost, sand, and gravel for gardens, yards, and beds.
For construction projects – Concrete foundations, gravel driveways, crushed stone bases, and fill dirt.
During excavation planning – Determine how much dirt will be removed for basements, pools, or grading.
When comparing suppliers – Convert all quotes to cubic yards to compare pricing fairly.
For waste removal – Estimate dumpster or truckload volumes for debris and spoils.
Don’t use cubic yards for: Paint coverage (square feet), lumber (board feet), liquids (gallons), or lightweight materials sold by the bag (though bags often convert to cubic yards for bulk ordering).
Forgetting to convert depth from inches – The most frequent error. Always divide inches by 12 before multiplying.
Skipping the ÷27 – Cubic feet is NOT cubic yards. One cubic yard equals 27 cubic feet.
Mixing units without converting – Feet × inches × centimeters gives nonsense results. Convert everything to one unit (feet) first.
Measuring sloped surfaces incorrectly – Measure the horizontal distance, not the slope length. For a 10-foot sloped driveway, the horizontal length might be 9.5 feet.
Ignoring irregular shapes – For circles, use π × radius² × depth. For triangles, use (base × height ÷ 2) × depth.
Ordering exact calculated amount – Always add 10–15% for compaction, settling, spillage, and irregular areas.
You’re installing a 12×14 foot patio with a 6-inch gravel base, 1-inch sand layer, and 4-inch concrete pavers on top.
Gravel base calculation:
Area: 12 ft × 14 ft = 168 sq ft
Depth: 6 inches ÷ 12 = 0.5 ft
Cubic feet: 168 × 0.5 = 84 ft³
Cubic yards: 84 ÷ 27 = 3.11 cubic yards
With 15% compaction buffer: 3.58 cubic yards ordered
Sand layer calculation:
Depth: 1 inch ÷ 12 = 0.083 ft
Cubic feet: 168 × 0.083 = 13.94 ft³
Cubic yards: 13.94 ÷ 27 = 0.52 cubic yards
Total material needed: 4.1 cubic yards (gravel + sand)
At $55 per yard for gravel and $45 per yard for sand, the cubic yard calculator shows:
Gravel cost: 3.58 × $55 = $196.90
Sand cost: 0.52 × $45 = $23.40
Total material cost before pavers: $220.30
This calculator prevents underestimating by handling depth conversions automatically and including compaction factors in your decision-making.

The calculator is mathematically exact to 2 decimal places based on your inputs. Accuracy depends on your measurements—use a tape measure and take multiple depth readings for best results.
Yes. Multiply length (ft) × width (ft) × depth (ft) = cubic feet. Then divide cubic feet by 27. Convert all measurements to feet first.
Check your unit selections for depth. Switching depth from inches to feet multiplies your result by 12. Also verify all three dimensions have appropriate units for your project.
Yes. The formula (length × width × depth ÷ 27) is the industry standard used by landscapers, concrete contractors, and excavation professionals worldwide.
Cubic feet measure volume in foot increments. One cubic yard equals 27 cubic feet. Cubic yards are used for bulk materials because the numbers are smaller and more practical (1.5 yards vs 40.5 cubic feet).
Yes. Select meters or centimeters for any dimension. All values convert automatically to feet before calculation, returning cubic yards and cubic feet results.
The cost row hides when price per cubic yard is zero. Enter a price above 0 to see total cost displayed.
This calculator assumes rectangular areas. For circles, use π × radius² (in feet) for area, then multiply by depth in feet and divide by 27. For triangles, use (base × height ÷ 2) for area.

Order 10–15% extra for most materials. For compacting materials like gravel and crushed stone, add 15–20%. For mulch and compost, 10% is usually sufficient.
Yes. Concrete is sold by the cubic yard. Enter your slab or footing dimensions, use the price per cubic yard, and add 5–10% for spillage and form variations. Most concrete trucks charge for the full yard even if you use less.
Volume calculations are identical for all materials—one cubic yard occupies the same space regardless of material type. However, weight varies dramatically (sand weighs more than mulch). For weight limits (truck capacity, trailer towing), check material density separately.
