Sand Calculator

Estimate sand in cubic yards, tons, bags, and cost for pavers, patios, sandboxes, pool bases, landscaping, and fill projects.

Project setup

Estimate sand for paver bedding, patios, sandboxes, pool bases, landscaping, and fill projects.

Use this for a rectangular patio, bed, base layer, or fill area.

Overage percentage

Extra sand helps cover compaction, moisture changes, uneven ground, and spreading waste.

Leave blank if you only need quantities.

Density note

Actual sand density varies by material, moisture, compaction, and supplier. Use your supplier's density when available.

Enter the area and depth to estimate sand in cubic yards, tons, bags, and cost. For best results, use your supplier's sand density when available.

Choose a mode, enter measurements, then review volume, weight, bags, and optional cost.

Sand calculator formulas

Rectangle area = length x width.

Circle area = pi x radius squared.

Volume in cubic feet = area in square feet x depth in feet.

Cubic yards = cubic feet / 27.

Cubic meters = cubic feet / 35.3147.

Tons = cubic yards x sand density.

Total with overage = amount x (1 + overage % / 100).

Cost = amount x selected price unit.

Worked examples

A 200 sq ft patio at 1 inch deep is 16.67 cu ft, or 0.617 cu yd before overage. With 10% overage, plan about 0.679 cu yd. At 1.35 tons/cu yd, that is about 0.92 tons.

An 8 ft x 8 ft sandbox at 6 inches deep is 32 cu ft, or about 1.185 cu yd before overage.

If the total is 32 cu ft and each bag is 0.5 cu ft, the estimate is 64 bags. If the math gives 64.2 bags, round up to 65.

Sand depth, bags, and bulk ordering notes

Paver bedding and patio leveling layers often use a shallow sand layer, while sandboxes, pool bases, landscaping, and fill projects can use much deeper layers. Always match the depth to your project plan or supplier guidance.

Bag estimates are useful for small projects because bags are usually sold by volume. For larger projects, bulk sand may be more practical, but suppliers may quote by cubic yard, ton, delivery load, or minimum order.

Sand weight is only an estimate here. Moisture, compaction, grain type, and supplier measurement can change the actual tons per cubic yard, so use supplier density when available.

Common sand estimate mistakes

  • Using inches as feet for depth instead of converting first.
  • Forgetting overage for compaction, spreading loss, and uneven ground.
  • Confusing cubic yards and tons when comparing supplier quotes.
  • Using the wrong sand density for the selected material.
  • Ignoring moisture and compaction.
  • Buying by bag when bulk delivery may be more practical.
  • Not checking supplier minimum order, bag coverage, or delivery rules.

Quick answers

What this calculator answers

  • Result: Estimate sand in cubic yards, tons, cubic feet, cubic meters, bags, and optional cost.
  • Method: Area times depth gives cubic feet, then cubic feet divided by 27 gives cubic yards.
  • Project planning: Use depth, density, and overage for pavers, patios, sandboxes, pool bases, landscaping, and fill estimates. sand coverage and depth guide

Accuracy and limitations

Calzivo tools are built for practical estimates, conversions, and checks. Some tools use standard formulas or simplified assumptions, and results can be affected by input accuracy, rounding, units, local rules, or changing official requirements.

Construction estimates can vary with site conditions, waste, compaction, product coverage, local requirements, and measurement accuracy. Verify material orders before purchasing.

How to Use This Tool

Use these steps to enter the right inputs and interpret the result correctly.

1

Choose rectangle, paver bedding, sandbox, base/leveling layer, circle, multiple areas, or manual area input.

2

Select a project mode or preset, then adjust depth if your plan uses a different layer thickness.

3

Choose sand type or enter supplier density.

4

Add overage, bag size, and price if you want a buying estimate.

5

Review cubic yards, tons, bags, and cost before ordering.

Frequently Asked Questions

Common questions about Sand Calculator and how to read the result.

How do I calculate how much sand I need?

Calculate area, multiply by depth in feet to get cubic feet, divide by 27 for cubic yards, then multiply by sand density for tons.

How many cubic yards of sand do I need?

Cubic yards equal cubic feet divided by 27. This calculator shows cubic yards after applying your selected overage.

How many tons of sand are in a cubic yard?

Many sand types are roughly 1.25 to 1.40 tons per cubic yard, but moisture, compaction, and supplier measurement can change the real value.

How deep should sand be for pavers?

A common bedding layer is about 1 inch, but project requirements vary by paver system, base preparation, and local conditions.

How much sand do I need for a sandbox?

Multiply sandbox length by width by desired sand depth. A deeper sandbox can require much more sand than expected.

Should I order extra sand?

Often yes. Overage helps cover compaction, moisture changes, spreading loss, and uneven ground.

Why does sand density vary?

Sand density changes with type, grain size, moisture, compaction, void space, and supplier measurement methods.
