Patio Sand Calculator

Last updated July 11, 2026

For a 1 inch bedding layer with 10% allowance, a 10x10 patio needs about 0.34 cubic yards or 19 half-cubic-foot bags of sand. A 12x12 patio needs about 0.49 cubic yards or 27 bags. Use the calculator below for your area, depth, and bag size.

Quick answer

  • A 10x10 patio needs about 0.34 cu yd or 19 half-cubic-foot bags of bedding sand.
  • A 12x12 patio needs about 0.49 cu yd or 27 half-cubic-foot bags.
  • Use the sand layer for setting pavers, not for fixing an uneven or poorly compacted base.

Calculate paving sand by area

The formula is patio area x bedding sand depth. For a 1 inch layer, divide the square footage by 12 to get cubic feet before allowance, then add waste and convert to cubic yards or bags.

This page targets patio sand, paver sand, and paving sand wording because homeowners and suppliers use those terms interchangeably for the screeded bedding layer.

Bedding sand is not base material

Keep the bedding layer consistent. If the patio grade is low, correct the compacted base rather than adding extra sand.

Use the paver base calculator for road base, base rock, or crushed aggregate under the sand layer.
