Calculate how much sand you need for your project. Free online sand calculator with volume, weight, and bag estimation.
The sand calculator helps you estimate how much sand you need for construction, landscaping, or fill projects. Enter the area dimensions and depth to calculate volume, weight, and number of bags. Construction sand weighs about 100 lb per cubic foot or 2,700 lb per cubic yard.
Volume (cu ft) = Length × Width × (Depth / 12) | Weight = Volume (cu yd) × 2,700 lbsDepth is converted from inches to feet by dividing by 12. One cubic yard equals 27 cubic feet. Construction sand has a typical density of approximately 2,700 lbs per cubic yard (100 lb/cu ft). Actual weight may vary by sand type and moisture content.
