Key Takeaways
- Sand is sold by the cubic yard or by weight (tons)
- Always add 10% extra for compaction, spillage, and irregular surfaces
- 1 cubic yard of sand weighs approximately 1.35 tons (2,700 lbs)
- Paver base typically requires 2 inches of sand depth
- Sandboxes need 8-12 inches of depth for proper play
Understanding Sand Calculations
Sand is sold by volume (cubic yards) or by weight (tons) for bulk delivery, or in bags for smaller projects. Accurately calculating your sand needs prevents costly overages or project delays from running short.
Types of Sand and Their Uses
| Sand Type | Best Uses | Approx. Cost/yd3 |
|---|---|---|
| Fill Sand | Backfilling, base material, drainage | $20-30 |
| Concrete Sand | Mixing concrete, masonry work | $25-35 |
| Mason Sand | Mortar, pavers, volleyball courts | $30-40 |
| Play Sand | Sandboxes, playgrounds, zen gardens | $35-50 |
| Paver Sand | Leveling base for pavers and stepping stones | $30-40 |
| Polymeric Sand | Filling joints between pavers (hardens) | $80-120 |
Recommended Sand Depths
| Application | Depth | Notes |
|---|---|---|
| Leveling/Smoothing | 1 inch | For minor surface corrections |
| Paver Base | 1-2 inches | After compaction, over gravel base |
| Patio/Walkway Base | 2-3 inches | For stable, level surface |
| Sandbox (Kids) | 8-12 inches | Deep enough for digging |
| Horseshoe Pit | 4 inches | In pit area only |
| Beach Volleyball | 12-18 inches | Requires mason or play sand |
Pro Tip: Ordering Sand
For bulk delivery, most suppliers have a minimum order of 1-2 cubic yards. For smaller projects, consider buying 50 lb bags from a hardware store - each bag covers approximately 0.5 cubic feet. Always verify delivery access to your property before ordering bulk sand.
Sand Calculator Formula
The basic formula for calculating sand volume is:
- Rectangular: Length (ft) x Width (ft) x Depth (ft) = Cubic Feet
- Circular: Pi x (Radius)2 x Depth = Cubic Feet
- To convert to cubic yards: Cubic Feet / 27 = Cubic Yards
- To convert to tons: Cubic Yards x 1.35 = Tons (approximate)
Tips for Success
- Always measure your area twice before ordering
- Add 10% extra for compaction, waste, and irregular edges
- Compact base sand before laying pavers
- Keep sand dry during storage to maintain workability
- Use landscape fabric under sand to prevent mixing with soil
- Wet sand before compacting for better results
- Consider drainage needs when planning depth
Bagged vs Bulk Sand
For projects requiring less than 1/2 cubic yard, bagged sand from a hardware store is often more convenient. For larger projects, bulk delivery is more economical. A standard 50 lb bag of sand covers approximately 0.5 cubic feet, so you would need about 54 bags to equal one cubic yard.
