What Is This Tool?
The Cubic Yards Calculator works out the volume of a shape from its dimensions and returns the result in cubic yards, cubic feet, and cubic meters at the same time. It supports seven shapes — square, rectangle, rectangle with borders, circle, circle border, round with borders, triangle, and trapezoid — and lets you enter measurements in either centimeters or inches. You can also add a quantity and unit price to turn the volume into a quick material cost estimate, then download the result as a PDF.
How to Use This Tool?
- Select the shape that matches your area using the shape icons at the top.
- Toggle metric or imperial, then enter the required dimensions and the depth.
- Optionally enter quantity, price, and price-per-unit under Options for a cost estimate.
- Click Calculate to see the volume in all three units, then download the PDF if needed.
Key Features
- Seven shape modes: square, rectangle, rectangle with borders, round (circle and circle border), round with borders, triangle, and trapezoid.
- Outputs volume in three units at once — cubic yards, cubic feet, and cubic meters.
- Metric/imperial switch lets you enter dimensions in centimeters or inches with automatic conversion.
- Material cost estimate from quantity, unit price, and price-per-unit (cubic yard, foot, or meter).
- One-click PDF download of the calculated result.
Examples
- A square slab 49 cm per side at 95 cm depth returns its volume across cubic yards, feet, and meters.
- A rectangular bed measuring 49 × 95 cm at 95 cm depth uses length × width × depth.
- A circle 49 cm in diameter at 95 cm depth uses π × (diameter ÷ 2)² × depth.
- A triangle with 7, 6, and 5 cm sides at 95 cm depth uses Heron's formula for the area, then multiplies by depth.
Common Use Cases
- Estimating concrete needed for slabs, footings, or pads.
- Calculating soil, mulch, or compost for garden beds and borders.
- Sizing gravel or aggregate fill for paths and driveways.
- Working out fill volume for round, bordered, or trapezoidal planters and tanks.
- Budgeting a material purchase by converting volume into a cost estimate.
Tips & Best Practices
- Pick one measurement system before entering values and keep all dimensions consistent.
- Use the depth field for the full thickness of material, not just the surface dimensions.
- For bordered shapes, enter the inner dimensions and the border width in their separate labeled fields.
- Add a small overage to your quantity to cover compaction, settling, or waste.
- Match the price-per-unit setting to how your supplier quotes — per cubic yard, foot, or meter.
Limitations
- It covers seven preset shapes only; irregular or composite areas must be split and added up manually.
- Results assume exact measurements and a uniform depth, and don't account for slope, compaction, or settling.
- The cost figure is a simple price × quantity × volume estimate and excludes tax, delivery, and waste.
- Nothing is saved between sessions — only the current result can be exported as a PDF.
Frequently Asked Questions
- Does it only calculate cubic yards?
- No — despite the name, it shows the volume in cubic yards, cubic feet, and cubic meters at the same time.
- Can I enter measurements in inches instead of centimeters?
- Yes. Use the metric/imperial switch and your values are converted automatically.
- How is the price calculated?
- It multiplies your unit price by the quantity and the volume in the unit you choose — cubic yard, foot, or meter.
- Which shapes are supported?
- Square, rectangle, rectangle with borders, circle, circle border, round with borders, triangle, and trapezoid.
Key Terminology
- Volume
- The amount of three-dimensional space a shape occupies, expressed here in cubic units.
- Depth
- The thickness or height of material, multiplied by the area to produce volume.
- Cubic yard
- A unit of volume equal to a cube one yard on each side, commonly used for bulk materials.
- Border width
- The thickness of the surrounding frame in bordered shapes, added around the inner area.
- Heron's formula
- A method for finding a triangle's area from the lengths of its three sides.
