How to Use the Sand Calculator
- Select Unit System: Choose between Imperial (feet/inches) or Metric (meters/cm) based on your measurements
- Choose Input Method: Select Area & Depth if you know the dimensions, or Known Volume if you already calculated the cubic volume
- Pick Sand Type: Different sand types have varying densities and costs - select the one matching your project needs
- Enter Measurements: Input length, width, and depth for area calculations, or direct volume for known quantities
- Adjust Waste Factor: Set waste percentage based on project complexity (typically 10-15% for most jobs)
- Review Results: Check volume needed, weight in tons, bag count, estimated cost, and coverage area
Sand Types and Applications
General Purpose Sand
All-around sand suitable for most construction and landscaping tasks. This versatile option works well for filling gaps, leveling surfaces, and mixing with other materials. Medium grain size provides good compaction while remaining workable for various applications.
- • Base layers for pavers and patios
- • General fill material
- • Playground surfaces
- • Leveling applications
Masonry Sand
Fine, clean sand specifically processed for mortar and masonry work. Particles are uniformly sized and free from debris, making it ideal for brick laying, block work, and stucco applications. Higher density than general sand provides stronger bonding in mortar mixes.
- • Bricklaying mortar
- • Concrete block work
- • Stucco and plaster
- • Paving stone joints
Play Sand
Specially cleaned and screened sand that meets safety standards for children's play areas. Fine texture is soft on skin while remaining firm enough for sandcastle building. Undergoes washing and filtering to remove dust, debris, and potentially harmful materials.
- • Sandboxes and play areas
- • Volleyball courts
- • Beach-style landscaping
- • Safe children's surfaces
Fill Sand
Economical coarse sand used for large-scale filling and grading projects. Contains mixed particle sizes that compact well, making it excellent for raising ground levels and filling low spots. Higher density provides maximum coverage per ton compared to finer sands.
- • Backfilling trenches
- • Site grading and leveling
- • Foundation preparation
- • Large area filling
Sand Project Guidelines
Depth Recommendations
Sand layer beneath pavers provides leveling and drainage. Compact thoroughly for stable surface.
Sufficient depth for children to dig and play comfortably. Allows for settling over time.
Creates level base and drainage layer under synthetic grass installations.
Calculating Sand for Common Projects
Measure patio dimensions in feet. Use 1-2 inch depth for sand base. A 12x16 foot patio needs approximately 0.74 cubic yards of sand at 1.5 inch depth. Add 10% waste for leveling adjustments and spillage during installation.
Standard 5x5 foot sandbox at 12 inches deep requires 0.93 cubic yards of play sand. Order slightly more since sand compacts when children use it. Plan to top up annually as sand disperses during play.
Three-foot wide path at 2 inches deep uses 0.019 cubic yards per linear foot. A 20-foot path needs 0.37 cubic yards total. Compact sand base before laying stepping stones or pavers for long-lasting results.
Tips and Best Practices
Ordering and Delivery
- Buy Extra: Always order 10-15% more than calculated. Sand compacts during delivery and installation, and you want enough material to complete the job without delays.
- Delivery Access: Ensure trucks can reach the installation site. Dumping closer to work area saves hours of wheelbarrow trips and physical labor.
- Bulk vs Bags: Buying bulk sand costs less for projects over 1 cubic yard. Bagged sand works better for small jobs and offers easier storage.
- Moisture Content: Wet sand weighs more than dry sand. If ordering by weight, account for moisture which can add 20% to total weight.
Installation Tips
- Compaction Matters: Compact sand in 2-inch layers using a plate compactor. Multiple thin layers compact better than one thick layer.
- Screening Level: Use a straight board or screed to level sand perfectly. This ensures pavers or stones sit uniformly without rocking.
- Weed Barrier: Install landscape fabric beneath sand for patios and paths. Prevents weeds growing through while allowing water drainage.
- Edge Restraints: Install borders before adding sand. Edges contain material and prevent spreading beyond project boundaries.
Frequently Asked Questions
How much does a cubic yard of sand weigh?
A cubic yard of sand typically weighs between 2,400 to 2,700 pounds (1.2 to 1.35 tons) depending on moisture content and sand type. Dry sand weighs less than wet sand. Coarse sand weighs slightly more than fine sand due to packing density.
Can I use regular sand for my sandbox?
No, always use play sand for sandboxes and children's areas. Play sand is specially washed and screened to remove dust, silica, and contaminants. Regular construction sand may contain harmful materials and creates excessive dust that irritates eyes and lungs.
How many bags of sand equal one cubic yard?
One cubic yard equals approximately 54 fifty-pound bags of sand. For smaller quantities, remember that one 50-lb bag covers about 0.5 square feet at 2 inches deep. Bulk delivery becomes more economical when you need more than 20-30 bags.
Should I compact sand before or after laying pavers?
Compact sand thoroughly before laying pavers. Use a plate compactor to create a firm, level base. After placing pavers, sweep polymeric sand into joints and mist with water to lock pavers in place. Never compact after pavers are down as this may crack them.
What's the difference between masonry sand and concrete sand?
Masonry sand has finer, more uniform particles ideal for mortar and laying bricks. Concrete sand contains coarser particles with varied sizes that provide strength when mixed with cement for concrete. Using the wrong type affects strength and workability of your project.
How long does sand last in outdoor applications?
Sand used as paver base or in construction lasts indefinitely when properly installed. Play sand in sandboxes needs replacement every 2-3 years as it breaks down and gets contaminated. Joint sand between pavers may need replenishment every 3-5 years depending on weather and traffic.
