Sand Calculator in Cubic Yards, Tons & 50-lb Bags

Calculate construction and masonry sand volume in cubic feet, cubic yards, tons, and 50-lb bags with compaction allowance.

Quick Answer:To calculate sand: multiply length × width × depth in feet to get cubic feet, divide by 27 for cubic yards, and multiply by 1.4 tons/yd³ for tonnage.

How to Use the Sand Calculator (Cubic Yards, Tons & Bags)

1Enter the length and width of the coverage area in feet.
2Enter the sand depth in inches (standard paver bedding is 1 inch).
3Adjust the compaction / waste percentage (5% to 10% is standard).
4View the calculated volume in cubic yards, weight in tons, and equivalent 50-lb bag count.

Formula & How It Works

ASTM C33 Aggregate Density Standard

Tons = (L × W × (D / 12) / 27) × 1.4

Volume (cu ft) = L × W × (Depth in inches / 12). Cubic Yards = cu ft / 27. Weight (tons) = Cubic Yards × 1.4 tons/yd³ (dry sand bulk density ~100–110 lbs/cu ft).

Worked Examples

10x10 Patio Paver Sand Base (1 inch depth)

Input: 10' L × 10' W, 1" Depth, 5% waste

Explanation: 100 sq ft × (1/12 ft) = 8.33 cu ft + 5% compaction = 8.75 cu ft = 0.32 cubic yards = ~900 lbs (18 bags).

Result: 8.75 cu ft, 0.32 cu yds, 0.45 tons, 18 bags (50-lb)

Children's Sandbox (8x8 ft, 6 inches depth)

Input: 8' L × 8' W, 6" Depth

Explanation: 64 sq ft × 0.5 ft depth = 32 cu ft + 5% = 33.6 cu ft.

Result: 33.6 cu ft, 1.24 cu yds, 1.74 tons, 70 bags

Above-Ground Pool Base (24 ft diameter circular pool)

Input: 24' L × 24' W (approx 452 sq ft area), 2" Depth

Explanation: Provides smooth base cushion beneath vinyl swimming pool liners.

Result: 79.1 cu ft, 2.93 cu yds, 4.10 tons

Frequently Asked Questions

How much does one cubic yard of sand weigh?▼

One cubic yard of dry sand weighs approximately 2,600 to 2,800 lbs (roughly 1.3 to 1.4 US tons); wet sand weighs up to 3,000 lbs (1.5 tons).

How many 50-lb bags of sand are in a cubic yard?▼

There are approximately 54 fifty-pound bags in one cubic yard of sand (2,700 lbs / 50 lbs).

How deep should sand be under patio pavers?▼

Standard ICPI (Interlocking Concrete Pavement Institute) guidelines call for exactly 1 inch of uncompacted coarse concrete sand over a compacted gravel base.

What sand should be used for a sandbox?▼

Use washed, non-toxic play sand or fine mason sand that is free of crystalline silica dust.

Does sand compact when installed?▼

Yes, sand typically compacts by about 5% to 8% when leveled and tamped, which is why a waste buffer is essential.

Is this calculation private?▼

Yes, everything runs directly in your browser with no uploaded data.

Quick Reference & Conversion Table

Area (sq ft)	Depth	Cubic Feet	Cubic Yards	US Tons	50-lb Bags
50 sq ft	1 inch	4.4 cu ft	0.16 yd³	0.23 tons	9 bags
100 sq ft	1 inch	8.8 cu ft	0.32 yd³	0.45 tons	18 bags
100 sq ft	2 inches	17.5 cu ft	0.65 yd³	0.91 tons	36 bags
200 sq ft	1 inch	17.5 cu ft	0.65 yd³	0.91 tons	36 bags
500 sq ft	1 inch	43.8 cu ft	1.62 yd³	2.27 tons	91 bags

⚠️ Common Pitfalls to Avoid

•Entering depth in feet instead of inches.
•Forgetting that sand compacts when tamped down (typically loses 5% to 8% volume).
•Buying small 50-lb bags for large projects where bulk quarry delivery by the ton is 70% cheaper.

💡 Practical Real-World Uses

•Paver patio, walkway, and driveway bedding sand layers.
•Masonry mortar preparation for bricklaying and stone setting.
•Equestrian arena footing, volleyball courts, and children's sandboxes.

Mason Sand vs Concrete Sand

✓Concrete sand (ASTM C33) has coarse, angular grains that lock together, making it ideal for paver bedding and concrete mixing.
✓Mason sand is fine, washed, and sifted, making it ideal for mortar joints, sandboxes, and pools.
