Calculate exactly how much sand you need — cubic yards, tons, bags, cost, and coverage — for any construction or landscaping project.
1. Choose your shape: Rectangle for slabs and beds, Circle for round areas, Path/Strip for walkways and borders.
2. Adjust dimensions: Default values are pre-filled (10×10 ft, 2 in deep). Use depth preset chips or type any value. Toggle Imperial / Metric at any time.
3. Select sand type: Each type has a different density — the calculator adjusts automatically. A tip appears explaining the best use.
4. Set waste factor: 10% is recommended. Increase for uneven terrain or irregular shapes.
5. Optional cost: Enter price per ton or per cubic yard — whichever your supplier quotes.
Depth guide for common applications:
| Application | Recommended Depth | Sand Type |
|---|---|---|
| Paver base / bedding layer | 1 inch | Concrete sand or paver base sand |
| Sandbox (children's play area) | 6–12 inches | Play sand (washed & screened) |
| Concrete mixing sub-base | 2–4 inches | Concrete sand (dry) |
| Backfill / levelling | 4–6 inches | Fill sand |
| Mortar / masonry bedding | Variable | Mason sand |
| Volleyball court / sports surface | 12–18 inches | Mason sand or play sand |
| Above-ground pool base | 2–3 inches | Mason sand |
| Trench bedding / pipe surround | 6 inches min | Fill sand (compactable) |
Bags vs. Bulk: For projects under 0.5 cu yd (~700 lbs), bags are convenient. Over that threshold, bulk delivery is far cheaper — typically $25–$55/ton vs. $5–$7 per 50 lb bag at retail.
