How to Use This Calculator
Enter your input values
Fill in all required input fields for the Sand Calculator. Most fields include unit selectors so you can work in your preferred unit system — metric or imperial, whichever matches your problem.
Review your inputs
Double-check that all values are correct and that you have selected the right units for each field. Incorrect units are the most common source of calculation errors and can produce results that are off by factors of 2, 10, or more.
Read the results
The Sand Calculator instantly computes the output and displays results with units clearly labeled. All calculations happen in your browser — no loading time and no data sent to a server.
Explore parameter sensitivity
Try adjusting individual input values to see how the output changes. This is a quick and effective way to develop intuition about how different parameters influence the result and to identify which inputs have the largest effect.

About Sand Calculator
Sand serves countless roles in construction: as a base for pavers and flagstone, a component of mortar and concrete mixes, fill material for leveling, and even play sand for children's areas. This calculator helps you determine the exact volume and weight of sand required for your project. Because sand is typically sold by the cubic yard or by the ton, the calculator provides both units so you can compare supplier quotes directly. Sand density varies depending on moisture content and grain size -- dry sand weighs about 100 pounds per cubic foot, while wet sand can weigh 120 pounds or more. Entering the correct density ensures an accurate weight estimate, which is especially important for delivery and cost calculations.
The Math Behind It
Formula Reference
Sand Volume
V = L x W x (D / 12)
Variables: L, W in feet; D in inches
Worked Examples
Example 1: Paver bed 15 ft x 10 ft, 1 inch deep
Length = 15 ft, Width = 10 ft, Depth = 1 in, Density = 100 lb/cu ft
You need about 0.46 cubic yards or 0.63 tons of sand.
Common Mistakes & Tips
- !Not accounting for moisture -- wet sand is significantly heavier than dry sand.
- !Forgetting to compact bedding sand, which reduces depth by 20-25 percent.
- !Using the wrong type of sand for the application (e.g., play sand instead of mason sand for mortar).

Frequently Asked Questions
How much does a cubic yard of sand weigh?
Dry sand weighs about 2,700 pounds (1.35 tons) per cubic yard. Wet sand can weigh up to 3,240 pounds (1.62 tons) per cubic yard.
What type of sand should I use for pavers?
Use mason sand (also called concrete sand or paver sand) for the bedding layer. For the joint fill between pavers, polymeric sand is recommended as it hardens and resists weed growth.
