Sand calculator
Enter the area and depth of sand. You get cubic yards, tons, and an optional cost estimate.
Figures last reviewed October 2026. See sources.
Density used
Default density is 100 lb per cubic foot, about 1.35 tons per cubic yard. Dry sand is commonly quoted at about 1.3 to 1.5 tons per cubic yard and damp sand at about 1.5 to 1.7, so choose the option that fits or enter your supplier's number.
Depth: typical ranges
These are common ranges, not requirements. Your soil, climate, and local rules may call for something different.
| Use | Depth |
|---|---|
| Paver bedding layer | About 1 in |
| Sandbox | 6 in or more |
How this is calculated
Area times depth gives volume in cubic feet. Divide by 27 for cubic yards. Multiply by the density and divide by 2,000 to get tons.
A thin bedding layer is easy to over- or under-order because small depth errors change the total a lot. Check the finished depth after screeding, and keep a little extra.
Example: a 10 ft by 10 ft area at 1 inches deep, with 5% extra, needs about 0.44 tons (0.32 cubic yards).
How far does one ton go?
Area covered by one ton at different depths, before any extra material.
| Depth | Square feet covered |
|---|---|
| 1 in | 240 |
| 2 in | 120 |
| 4 in | 60 |
| 6 in | 40 |
Quick reference: common sizes
Amount needed in tons, including the default 5% extra. Use the calculator above for your exact size.
| Area | 1 in deep | 2 in deep |
|---|---|---|
| 10 × 10 ft | 0.44 | 0.88 |
| 10 × 20 ft | 0.88 | 1.75 |
| 12 × 12 ft | 0.63 | 1.26 |
| 20 × 20 ft | 1.75 | 3.50 |
Common questions
How much sand do I need?
Multiply the area in square feet by the depth in feet to get cubic feet, then divide by 27 for cubic yards. Multiply cubic feet by the density and divide by 2,000 for tons.
How many tons are in a cubic yard of sand?
At the default density, about 1.35 tons per cubic yard. Moisture and the type of sand change this.
How much sand goes under pavers?
A bedding layer of about 1 inch is commonly used, but follow your paver manufacturer's guidance, including the type of sand they recommend.
How much area does a ton of sand cover?
About 240 square feet at 1 inch deep and about 120 square feet at 2 inches deep.
Should I order extra sand?
A small allowance is common. The default is 5%. Change it under the advanced options.
Does moisture change how much sand I need?
The volume you need stays the same, but damp sand weighs more per cubic yard. If you buy by the ton, choose the damp option so the tonnage is not underestimated.
