Sand Calculator

Estimate sand volume and weight for patios and sandboxes.

What Is a Sand Calculator?

The sand calculator estimates how much sand you need for a sandbox, paver bedding, or patio base. Enter the length, width, and depth of the area to get the volume in cubic yards and the weight in tons.

How It Works

Volume = Length × Width × (Depth ÷ 12). Weight ≈ Cubic yards × 1.35 tons.

Example

A 6 ft × 6 ft sandbox at 6 in deep: 18 cu ft ≈ 0.67 cu yd → ~0.9 tons.

How to Calculate

  1. Measure the length and width of the area in feet. A 6 ft by 6 ft sandbox is 36 sq ft.
  2. Set the depth. Fill a sandbox 6 in deep, but use only about 1 in of leveling sand under pavers.
  3. Enter the dimensions. At 36 sq ft and 6 in deep, the volume is 18 cu ft, about 0.67 cubic yards.
  4. Read the weight. Sand weighs roughly 1.35 tons per cubic yard, so this comes to about 0.9 tons.
  5. Choose the right sand for the job, such as play sand for a sandbox or paver sand for patios.

Frequently Asked Questions

What kind of sand should I use?

Play sand for sandboxes, masonry/paver sand for patios, and coarse sand for mixing concrete.

How much does sand weigh?

Roughly 1.35 tons per cubic yard depending on moisture.

How deep for paver bedding?

Mason Reid founded MeasureThen after two decades of hands-on work in construction and estimating. Across residential and light commercial projects, he sized concrete pours, framed walls, hung drywall, and priced out roofing, fencing, and deck work — learning the exact math that every job depends on. At MeasureThen he writes the formulas, checks every calculator against real-world assumptions, and makes sure each one is simple enough for a homeowner to trust and a contractor to use. When he is not measuring twice, he is helping projects stay on budget.

Every MeasureThen calculator uses simple, transparent formulas and standard industry assumptions drawn from common construction practice. We show the math behind each result and include worked examples so you can follow along and double-check the numbers. Results are estimates: materials, labor, and pricing vary by region and market, so always confirm important figures with a licensed professional and your local building codes.
