Sand Calculator

This page answers a narrow question: how much material occupies an entered rectangular or circular layer after a stated allowance and an entered bulk density are applied. It does not decide whether a particular product is appropriate for a paver system, concrete, a sandbox, a pool installation, artificial turf, drainage, fill, or any other use. Those uses can have different project documents, product instructions, gradation, preparation, compaction, and safety requirements.

Start with the layer you are actually estimating. Record its limits, installed depth, product name, and supplier sales unit. Keep excavation, aggregate base, bedding, joint material, concrete, and surface material in separate lines. The Federal Highway Administration's geotechnical reference is useful context: bulk unit weight changes with factors such as moisture, density, and voids, so a material label alone cannot supply a universal purchasing conversion.

Choose the shape that matches the documented layer. The code first converts every linear dimension to feet, then calculates base volume:

The page also displays cubic meters as adjusted cubic feet × 0.0283168. NIST's unit tables document the inch, foot, cubic-yard, and metric-volume relationships used in these conversions. The circle input is diameter, not radius.

The form starts masonry, concrete, and polymeric sand at 100 lb/cu ft; play and fill sand at 95; and sharp sand at 105. Those values are editable conveniences used for arithmetic. They are not a statement that every product sold under those names has the same bulk weight, gradation, moisture condition, packaging, or suitability.

Selecting a sand label overwrites the density field, so enter and preserve the supplier's stated value after choosing the product. Ask for the exact name, product data or specification, sales unit, bulk unit weight or tons-per-yard conversion, bag weight if applicable, minimum order, and delivery basis. Concrete aggregate, for example, is a product with defined quality and gradation requirements; it should not be selected from a generic calculator menu alone.

If a supplier sells by bags, this tool can still give a bulk-volume or weight cross-check, but it does not count bags. Divide only after the supplier confirms the actual bag coverage or net weight and product instructions.

The 0% to 20% slider simply multiplies geometry before all later conversions. It is not a density test or a compaction model. A higher allowance might be a documented purchasing decision for irregular edges, handling, or delivery rounding; it cannot fix an uncertain depth, an uneven subgrade, a missing drainage plan, or an unspecified product.

Do not insert a generic depth merely because the form asks for one. The right layer thickness and preparation depend on the actual product and project scope. For a landscape or bulk-material ledger that begins with measured area and keeps delivery rounding visible, read How to Calculate Yardage. Use the Cubic Yard Calculator to cross-check a defined volume and the Gravel Calculator for a distinct granular layer; neither replaces design or product instructions.

For a round layer, the page calculates π × (diameter ÷ 2)² × depth. It does not calculate an oval, a rounded rectangle, a circle with cutouts, a partial circle, a slope, or a varying-depth layer. Split a complex outline into measured components and maintain a ledger rather than entering an approximate diameter.

That distinction is especially important near pools, paving, and turf. This page cannot decide whether sand is approved under a liner, whether a pool base is level, whether a paver assembly meets its manufacturer's instructions, whether a turf base drains, or whether sand needs compaction or containment. Stop at a transparent quantity and return to the appropriate project information for those questions.

Compare the quantity with the plan and supplier quote: verify the layer footprint, depth, shape, allowance, product, density, sale unit, price unit, packaging, delivery access, stockpile location, and any separate base, excavation, or drainage work. The 14-ton result is only a fractional division; it cannot tell you how many legal or available loads a supplier will deliver.

The optional cost is equally narrow: price per short ton times calculated short tons. It excludes delivery and every other unentered cost. Confirm the final order with the supplier and responsible project parties. If an input or result on this page seems unclear, you can report a calculator issue for review.
