How the sand calculator works
Area x depth gives volume; density gives weight. The calculator multiplies length x width x depth to get cubic feet, converts to cubic yards, then multiplies by 1.3 tons per cubic yard. A 10 ft x 10 ft area at 6 inches deep needs 50 cubic feet — about 1.85 cubic yards, or 2.41 tons, or 100 bags of 0.5 cubic foot sand.
Depth guidance: 2 inches for a sand pit or play area top-up, 4 to 6 inches for levelling under pavers or a pool base. Add 5% for compaction and uneven ground. For anything over a cubic yard, bulk delivery is far cheaper per yard than bags.
