Area covered by one ton of dry concrete sand (1.35 tons per cubic yard). Doubling the depth halves the coverage.

Sand Calculation Formula

Every sand calculator uses the same three steps, and you can check any result by hand:

Tons of sand = length × width × (depth ÷ 12) ÷ 27 × density

1. Sand volume

Multiply length by width in feet to get square feet, then by the depth in feet (inches ÷ 12). A 10 × 10 ft area 2 inches deep holds 100 × 0.167 = 16.7 cubic feet of sand.

2. Sand in cubic yards

Divide by 27, because a cubic yard is 3 × 3 × 3 feet: 16.7 ÷ 27 = 0.62 cubic yards.

3. Tons of sand

Multiply by the sand's weight in tons per cubic yard. Dry concrete sand is about 1.35, so 0.62 × 1.35 = 0.83 tons. Add 10 percent for spillage and settling and order about 0.9 tons, or 37 bags of 50 lb.

Sand Weight

Weight is what turns a sand volume into the tonnage a sand yard will load. Dry sand weighs about 100 lbs per cubic foot, but water fills the gaps between the grains and can add a fifth to that.

How Many Bags of Sand Do I Need?

A 50 lb bag of dry sand holds about half a cubic foot, so it takes about 54 bags to make a cubic yard and 40 bags to make a ton. One 50 lb bag covers roughly 6 sq ft at 1 inch deep or 3 sq ft at 2 inches. The sand calculator rounds bags up to the next whole bag. Bagged sand costs three to six times as much per ton as bulk, so once you need more than about a ton, delivery from a sand yard is usually cheaper.

Sand Types

Sand Cost

Bulk sand from a sand and gravel yard typically costs $15 to $30 per ton for fill sand, $30 to $50 for concrete and masonry sand, and $40 to $80 for washed play sand or silica sand. Delivery adds $75 to $200 per load. A 50 lb bag of all-purpose or play sand costs $5 to $8 at a home center. Enter your local price per ton and the sand calculator adds the material cost to the result.

Sand Calculator FAQ

How do I calculate how much sand I need?

Multiply length by width by depth in feet to get cubic feet, divide by 27 for cubic yards, then multiply by about 1.35 for tons of dry sand. A 10 by 10 ft area 2 inches deep needs 0.62 cubic yards, or about 0.83 tons of sand.

How much does a cubic yard of sand weigh?

A cubic yard of dry sand weighs about 2,600 to 2,700 lbs, or 1.30 to 1.35 tons. Wet sand can weigh 3,000 to 3,200 lbs per cubic yard.

How much area does a ton of sand cover?

One ton of dry sand covers about 240 sq ft at 1 inch deep, 120 sq ft at 2 inches, 80 sq ft at 3 inches and 60 sq ft at 4 inches.

How many bags of sand are in a yard?

About 54 bags of 50 lb sand make a cubic yard, because each bag holds roughly half a cubic foot and a cubic yard is 27 cubic feet.

How many cubic feet of sand are in a ton?

About 20 cubic feet. Dry sand weighs roughly 100 lbs per cubic foot, so a 2,000 lb ton fills about 20 cubic feet, or 0.74 cubic yards.
