Sand Calculator
A sand calculator is a material estimation tool used to determine the volume and weight of sand needed for pavers, sandboxes, play areas, or masonry projects. It provides results in cubic yards and tons.
How to use this calculator

Introduction to Sand Calculator
How to Use the Sand Calculator
- Measure the Project Area: Input the length and width of the area you need to cover in feet.
- Set the Desired Depth: Enter the thickness of the sand layer in inches. 1 inch is standard for paver leveling; 12 inches is common for play areas.
- Select Sand Type: Choose between beach/play sand, masonry sand, or fill sand. This affects the density and weight calculation.
- Account for Compaction: Add 15-20% extra if you plan to use a plate compactor, as sand compresses significantly when vibrating.
- Review Total Weight: The tool will provide the total volume in cubic yards and the weight in tons for bulk ordering.
Understanding Sand
Sand is typically sold by the ton at bulk yards, but by the cubic foot in bags at retail stores. One cubic yard of sand is equivalent to 27 cubic feet and generally weighs between 2,600 and 3,000 pounds (approx. 1.3 to 1.5 tons), depending on its moisture content. Wet sand is significantly heavier than dry sand, a factor our calculator considers to ensure your delivery truck isn't overloaded. When estimating for large projects, always round up to the nearest half-ton; quarries rarely sell in smaller increments for bulk delivery.
For paver projects, sand serves as the final leveling layer. A 1-inch bed of "concrete sand" (also called sharp sand) is laid over a compacted gravel base. The jagged grains of sharp sand interlock, preventing the pavers from shifting or "creeping" over time. For play areas, you should use "play sand," which has been washed and screened to remove dust and large pebbles, making it safer and cleaner for children. Understanding these material differences is key to project longevity. Additionally, "Polymeric Sand" is used to fill the joints *between* pavers; it contains a polymer that hardens when wet, locking the pavers together and preventing weed growth.
Environmental factors also play a role in sand management. Sand is highly prone to erosion from wind and water until it is secured by a top layer of pavers or contained within a sandbox frame. If you are storing sand on-site for more than a few days, it should be kept on a tarp and covered with another tarp to prevent it from washing into storm drains or becoming contaminated by local soil. Furthermore, the sieve size of sand determines its application; finer sands are used for finish masonry work, while coarser "torpedo sand" is used for structural concrete mixes.
Formula & Calculation Method
Volume is calculated as Area × Depth, then converted to yards. Weight is calculated by multiplying volume by the specific density of the sand type.
Example Calculation:
A 10x10 sandbox at 12 inches deep is 3.7 cubic yards. At 1.4 tons per yard, you need 5.18 tons of sand.
Tips for Accurate Results
- 1Always use a "weed barrier" fabric under sand in play areas to prevent soil and weeds from mixing with the clean sand.
- 2If you are using sand for a pool base, ensure it is perfectly level and free of any large rocks or debris that could puncture the liner.
- 3Order "Masonry Sand" for mortar mixes; it has a finer grain that allows for thinner, more consistent joints between bricks or blocks.
- 4When building a sandbox, ensure it has proper drainage at the bottom so it doesn't turn into a mud pit after a rainstorm.
- 5Keep sand covered when not in use to prevent it from becoming a litter box for neighborhood cats.
- 6If buying in bulk, have the truck dump the sand as close to the project area as possible; a ton of sand is roughly 15-20 wheelbarrow loads.
- 7Dampen the sand slightly before compacting it for pavers to help it pack tighter.
- 8Avoid using "Fill Sand" for pavers or play areas, as it often contains rocks, clay, and debris that make it difficult to level and uncomfortable for play.
- 9When mixing your own mortar, the standard ratio is 3 parts sand to 1 part masonry cement; use a consistent measuring bucket for every batch to ensure color matching.
- 10For athletic fields or volleyball courts, seek "silica-free" sand to protect the respiratory health of the players.
Key Facts About Sand
- •Sand density varies significantly based on moisture content; wet sand can be 20% heavier than dry sand.
- •Masonry sand is the standard for mortar, while concrete sand is used for structural work and paver bases.
- •One cubic yard of sand covers 324 square feet at 1 inch of depth.
- •Sand is a "non-compressible" material once the air gaps are removed, providing an excellent leveling surface.
- •Play sand should be certified for safety to ensure it doesn't contain crystalline silica dust.
- •Bulk delivery is usually 50-70% cheaper than buying sand by the bag for large projects.
- •The average dump truck can carry between 10 and 15 tons of sand per trip.
- •Sand is often sold by the "scoop" in smaller landscape yards, with one scoop typically equaling 0.5 to 1.0 cubic yards.
- •Washed sand is essential for pool filters and drainage systems to prevent clogging from fine silt.
- •Sand is the most consumed natural resource in the world after water, primarily used in construction and glass making.
Frequently Asked Questions
How much sand is in a ton?
One ton of sand is approximately 0.6 to 0.75 cubic yards, depending on the moisture content and grain size.
What is the best sand for pavers?
"Concrete sand" or "Sharp sand" is the best choice because its jagged edges interlock to create a stable base.
Is play sand different from regular sand?
Yes, play sand is washed, screened, and sometimes rounded to ensure it is clean, dust-free, and less abrasive for children.
How many bags of sand equal a yard?
If using standard 0.5 cubic foot bags, it takes 54 bags to equal one cubic yard.
Does sand expand when wet?
Yes, a phenomenon called "bulking" occurs where moisture increases the volume of sand. Our calculator uses a dry-weight standard for consistency.
What is "Concrete Sand"?
Concrete sand is a coarse-grained sand that has been washed and screened. It is the preferred base for pavers and an essential ingredient in many concrete mixes.
How deep should sand be under pavers?
A standard 1-inch layer of sand is recommended. If the sand is too deep, the pavers will be prone to shifting and sinking over time.
Can I use sand to level my lawn?
Yes, but you should use a mix of sand and topsoil (often 50/50). Pure sand can dry out too quickly and may not provide enough nutrients for the grass.
What is "Polymeric Sand"?
It is a specialized sand mixed with additives that harden when misted with water. It is used to fill the gaps between pavers to lock them in place and stop weeds.
How much does a cubic yard of sand weigh?
A standard cubic yard of dry sand weighs approximately 2,700 pounds. If the sand is wet, the weight can increase to over 3,000 pounds.
