Sand Calculator
Calculate how much sand you need by area and depth — cubic yards, estimated tons and bags. Paver bedding and leveling — usually a 1 in setting layer.

Sand at 1 in deep · density ≈ 1.35 tons/yd³ · 0.5 ft³ bags.
| Area ft² | Cubic yards | Tons (est.) | 0.5 ft³ bags |
|---|---|---|---|
| 50 ft² | 0.15 | 0.21 | 9 |
| 100 ft² | 0.31 | 0.42 | 17 |
| 200 ft² | 0.62 | 0.83 | 34 |
| 300 ft² | 0.93 | 1.25 | 50 |
| 500 ft² | 1.54 | 2.08 | 84 |
| 750 ft² | 2.31 | 3.13 | 125 |
| 1,000 ft² | 3.09 | 4.17 | 167 |
Per 100 ft² by depth
| Depth | Cubic yards | Tons | Bags |
|---|---|---|---|
| 1 in | 0.31 | 0.42 | 17 |
| 2 in | 0.62 | 0.83 | 34 |
| 3 in | 0.93 | 1.25 | 50 |
| 4 in | 1.23 | 1.67 | 67 |
| 6 in | 1.85 | 2.50 | 100 |
Tonnage is an estimate from loose, dry bulk density; damp or compacted material weighs more. Order ~5–10% extra for settling.
To find the right quantity of sand, multiply the area (length × width) by the depth and divide by 27 to convert cubic feet to cubic yards. This calculator does that automatically and also shows estimated tons and the number of bags you would need if buying in retail bags.
Bulk sand is usually sold by the cubic yard for delivery. The table above covers the most common project sizes at a 1 inches depth — if your depth differs, enter your exact dimensions in the main calculator. Always order about 5–10% extra to allow for settling, waste and uneven ground.
Frequently asked questions
How many cubic yards of sand do I need?
Multiply the area in square feet by the depth in feet, then divide by 27. For example, a 200 ft² bed at 1 in deep = 200 × 0.0833 ÷ 27 = 0.62 cubic yards.
How much does a cubic yard of sand weigh?
Sand weighs approximately 1.35 tons (2,700 lb) per cubic yard as loose, dry material. Damp or compacted material can weigh more — treat the tonnage as a planning estimate and confirm with your supplier.
How many bags of sand are in a cubic yard?
Sand bags are typically 0.5 ft³ bags. One cubic yard (27 cubic feet) takes roughly 54 bags. For any project bigger than a small area, bulk delivery by the yard is usually more economical.
