Sand Calculator – Estimate Volume and Weight Accurately
Whether you’re working on a sandbox, patio, trench, or foundation, this sand calculator helps you determine how much sand you need for your next DIY or landscaping project. Just input your dimensions and choose your sand type to get accurate volume and weight estimates.
Key Features
- Supports both metric and imperial measurement systems
- Choose between dry, damp, or wet sand densities
- Calculates sand volume in cubic yards or cubic meters
- Provides weight estimates in tons or tonnes
- Suggests bulk bag quantities based on standard 0.5 cubic yard bags
Sand Volume & Weight Formula
Imperial: (Length × Width × Depth in feet) ÷ 27 = cubic yards
Then: Cubic feet × sand density ÷ 2000 = weight in tons
Metric: (Length × Width × Depth in meters) = cubic meters
Then: Cubic meters × kg/m³ ÷ 1000 = weight in tonnes
Always order a bit extra to account for compaction and surface leveling. For best results, consult with your sand supplier to confirm the appropriate density.
Common Uses for Sand in Home Projects
Sand is a versatile material used across a wide range of construction and landscaping projects. Whether you're filling a sandbox, leveling a paver base, or creating a foundation bed, getting the correct sand volume and weight is essential to avoid shortfalls or overspending.
- Play Sand: Fine and clean sand for children’s sandboxes and play areas.
- Construction Sand: Used in concrete mixing, foundation leveling, and backfilling.
- Sharp Sand: Ideal for paving, block laying, and drainage applications.
Tips for Ordering Sand
- Round up your volume estimate to account for compaction or uneven ground.
- For paver or patio bases, consider layering with gravel beneath the sand for better drainage.
- When ordering in bulk, check how your supplier defines a “ton” or “yard”—some base it on dry sand weight, others on wet.
Frequently Asked Questions
How much sand do I need for a sandbox?
Use our sand calculator by entering the internal dimensions of your sandbox and desired depth (usually 6–12 inches). For example, a 5' × 5' box with 1 foot of sand needs about 0.93 cubic yards.
How deep should my sand base be for pavers?
For patios or walkways, a 1 to 2-inch layer of leveling sand is typical. Beneath that, a compacted gravel base of 4–6 inches is recommended for stability.
Can I use this calculator for pool installations?
Yes, this tool is ideal for calculating sand needed under above-ground pools. Just make sure to include extra for slope leveling and compacting.
