Sand Calculator
MATERIAL CALCULATOR
Estimate how much sand a rectangular area needs, including cubic yards, weight, overage, and material cost.
How it works
Area multiplied by depth gives volume. The calculator applies overage, then uses adjustable bulk density to estimate US short tons.
Formula
Cubic feet = length × width × depth ÷ 12 × (1 + overage)
Tons = cubic feet × density ÷ 2,000
Important limits
- Sand density changes with gradation, moisture, and compaction.
- Suppliers may sell by ton, cubic yard, bag, or minimum delivery.
- Allow for settlement and uneven subgrade where appropriate.
Frequently asked questions
How many cubic feet are in a cubic yard?
There are 27 cubic feet in one cubic yard.
Why can wet sand weigh more?
Moisture fills pore space and adds water mass, increasing bulk weight.
Planning a sand order
Measure the filled length, width, and compacted depth using the same unit before calculating volume. Sand settles during placement, and loose delivery volume may not equal the final compacted volume. Shape irregularities, grade changes, and spillage can also increase the quantity required.
Convert volume to weight only when a suitable bulk density is known. Moisture content and sand type can change weight substantially, so a supplier’s local value is better than a generic density. For bags, divide the required weight or volume by the amount listed on one bag and round up to a whole package. Consider adding a modest allowance for leveling and compaction, but avoid excessive surplus when storage or disposal is difficult.
Review notes
Volume and short-ton conversions were checked dimensionally; density remains user-adjustable. Last reviewed September 30, 2026.
