Sand Calculator – Estimate Cubic Yards, Tons & Weight
Use our free sand calculator to estimate how much sand you need in cubic yards, tons, and pounds. Enter dimensions and get instant results with cost estimate.
Sand Calculator Formula
Cubic Yards = (Length × Width × Depth in ft) ÷ 27; Tons = Cubic Yards × 1.35
How to Calculate Sand
- 1. Convert depth from inches to feet: Depth (ft) = Depth (in) ÷ 12
- 2. Calculate cubic yards: Cubic Yards = (Length × Width × Depth) ÷ 27
- 3. Calculate tons: Tons = Cubic Yards × 1.35 (sand density)
- 4. Calculate weight: Weight (lbs) = Cubic Yards × 2,700
- 5. Estimate cost: Cost = Cubic Yards × Price per Yard
Example Calculation
Let's say you're filling a 20ft × 10ft sandbox with 6 inches of sand.
- length: 20
- width: 10
- depth: 6
You need approximately 3.70 cubic yards or 5.00 tons of sand, weighing about 9,999 lbs
Tips
- Order 5–10% extra — sand compacts and settles, especially when wet
- Sand density is approximately 1.35 tons per cubic yard (2,700 lbs/yd³)
- Play sand and construction sand have different densities — play sand is lighter
- For paver base, use 1 inch of sand over 4-6 inches of gravel
Frequently Asked Questions
How much does a yard of sand weigh?
One cubic yard of sand weighs approximately 2,700 pounds (1.35 tons). The weight varies slightly depending on moisture content — wet sand can weigh up to 3,000 pounds per cubic yard.
How much does sand cost per cubic yard?
Sand costs between $15–$50 per cubic yard depending on the type and your location. Fill sand is cheapest ($15-25/yd³), while masonry sand and play sand cost more ($25-50/yd³). Delivery adds $50-100.
How much sand do I need for a sandbox?
For a rectangular sandbox, measure length × width × desired depth in inches. Calculate: Cubic Yards = (Length × Width × Depth ÷ 12) ÷ 27. A 4×4 foot sandbox with 12 inches of sand needs about 0.6 cubic yards.
