About Sand Calculations

Calculating the correct amount of sand for your project is crucial to avoid shortages or wastage. The volume of sand needed depends on the area to be covered and the desired depth.

Sand Density by Type
  • Play Sand: ~100 lb/ft³ (1,600 kg/m³)
  • Masonry Sand: ~105 lb/ft³ (1,680 kg/m³)
  • Concrete Sand: ~110 lb/ft³ (1,760 kg/m³)
  • Fill Sand: ~95 lb/ft³ (1,520 kg/m³)
  • Silica Sand: ~100 lb/ft³ (1,600 kg/m³)
Calculation Formulas

Volume Calculations:

  • Rectangular area: Volume = Length × Width × Depth
  • Circular area: Volume = π × (Diameter/2)² × Depth
  • Triangular area: Volume = (Base × Height × Depth) ÷ 2

Weight Calculation:

  • Weight = Volume × Density

Cost Calculation:

  • Cost = Weight × (Cost per unit weight)
  • Cost = Volume × (Cost per unit volume)
Tips for Purchasing Sand
  • Always add 5-10% extra to account for waste and settling
  • Sand is typically sold by weight (tons) or volume (cubic yards)
  • Check with suppliers for minimum order quantities and delivery fees
  • For small projects, bagged sand may be more practical than bulk delivery
Volume Formulas:
  • Rectangular Area: Volume = Length × Width × Depth
  • Circular Area: Volume = π × (Diameter ÷ 2)2 × Depth
  • Triangular Area: Volume = (Base × Height × Depth) ÷ 2
Weight Formula:

Weight = Volume × Density

Cost Formula:

Cost = Volume × Cost per Unit

What Is the Sand Calculator?

The Sand Calculator is a practical online tool that helps you estimate the amount of sand required for your construction or landscaping project. It calculates the total volume of sand needed, its approximate weight, and estimated cost based on your specific input measurements.

Whether you're filling a sandbox, preparing a foundation, or leveling ground for paving, this tool simplifies the process using common area shapes and a straightforward measurement converter. It saves time, reduces guesswork, and minimizes material waste.

How to Use the Sand Calculator

Follow these easy steps to get accurate sand estimates:

  • Select Calculation Type: Choose from Rectangular, Circular, Triangular area, or Direct Volume input.
  • Enter Measurements: Input your length, width, height, depth, or volume depending on your selection.
  • Choose Sand Type: Select the sand type based on your project — Play, Masonry, Concrete, Fill, Silica, or Custom Density.
  • Set Cost Details: Add the cost per unit (ton, cubic yard, bag, etc.) to estimate your total expenses.
  • Click “Calculate”: View total volume, weight, cost, and optional detailed steps.

Why This Calculator Is Useful

Accurately estimating sand requirements helps you:

  • Prevent over-purchasing or running short on materials
  • Plan your budget more effectively
  • Convert measurements using built-in conversion helper functions
  • Get instant results for both weight and volume in different units

It also serves as a helpful unit conversion tool — a feature common to various online converters like square feet to meters or cubic feet to cubic yards. If you’re working on projects where value conversion and material planning overlap, this calculator streamlines your workflow.

Sand Density Reference

The calculator uses average sand densities for each type:

  • Play Sand: ~100 lb/ft³
  • Masonry Sand: ~105 lb/ft³
  • Concrete Sand: ~110 lb/ft³
  • Fill Sand: ~95 lb/ft³
  • Silica Sand: ~100 lb/ft³

FAQ

Can I use this for metric measurements?

Yes. The measurement converter allows inputs in feet, meters, inches, and more. The conversion calculator automatically handles unit conversion in the background.

What if I have my own sand density?

You can select "Custom Density" and enter your value in either lb/ft³ or kg/m³. This makes the calculator flexible for unique materials.

How accurate are the results?

The results are estimates based on standard formulas and average densities. Always consider ordering 5–10% extra to cover waste or settling.

Is this just for sand?

While designed for sand, the tool works for any granular material with a known density. It's a general-purpose material volume and cost estimator.

Can I see the steps of the calculation?

Yes. By checking the “Show calculation steps” option, the tool displays each step in a detailed and easy-to-follow format.
