Stone Calculator
Calculate volume and weight of natural stone needed for a project.
Formula
Volume (cu yd) = L × W × D(ft) ÷ 27; Tons = cu yd × density
- Crushed stone/gravel: ~1.4 t/cu yd; Limestone: ~1.35; Fieldstone: ~1.5.
- Add 10% to volume for settling and waste.
- Sold in tons at most quarries and landscape suppliers.
20 ft × 10 ft, 3 in deep, crushed stone
Inputs
- Length: 20 ft
- Width: 10 ft
- Depth: 3 in
- Stone Density: 1.4
20 × 10 × 0.25 = 50 cu ft ÷ 27 = 1.85 cu yd × 1.4 = 2.59 tons.
