Volume needed = Length × Width × Depth, converted to cubic yards. Weight is estimated using a typical dry sand density of about 1.35 tons per cubic yard, a commonly cited planning figure, useful for play areas, paver bedding, garden paths, or as a base layer beneath other materials.
Play sand for a sandbox, leveling sand for pavers, and bedding sand for a paver base are all different products with slightly different properties, though this calculator's volume and weight math applies the same regardless of type. Depth requirements vary by use, a play area might use several inches, while paver bedding sand is typically just 1 inch.
For a 12 ft × 8 ft area, 2 inches deep: volume = 12 × 8 × (2 ÷ 12) = 16 cubic feet, or 16 ÷ 27 ≈ 0.593 cubic yards. Converting to weight at 1.35 tons per cubic yard: 0.593 × 1.35 ≈ 0.8 tons needed.
Entering depth in feet instead of inches, this calculator's depth field expects inches, entering the intended feet value directly would inflate the volume estimate twelvefold.
Assuming wet sand weighs the same as the dry sand density this calculator uses, wet sand can weigh noticeably more per cubic yard than the 1.35 tons per cubic yard dry estimate, adjust expectations if ordering damp material.
Using the same depth for every use case, a play area might need several inches of sand while paver bedding is typically just 1 inch, using the wrong depth for your specific application over- or under-orders material.
Yes, somewhat, moisture content and grain size affect density. 1.35 tons per cubic yard is a reasonable average estimate for dry sand; wet sand can weigh noticeably more per cubic yard.
The Paver Calculator includes a sand bedding estimate as one part of a larger paver project calculation (alongside paver count and gravel base). This calculator is a standalone, general-purpose sand estimator for any use, not tied to a paver project specifically.
For small quantities, bagged sand is convenient. For larger areas, generally more than a cubic yard or two, bulk delivery is usually significantly more cost-effective per unit of coverage.
