Gravel Calculator

Estimate crushed stone or pea gravel for driveways, paths and drainage layers. Volume comes from area × depth; weight uses a density you control (loose gravel is lighter than compacted crushed stone).

Calculation breakdown

  1. 1Volume: 29.73 × 0.102 × 1.10 compaction = 3.323 m³
  2. 2Weight: 3.323 × 1,551 kg/m³ = 5,152 kg
  • Landscape fabric under gravel suppresses weeds and keeps the stone out of the soil.

Volume = Area × Depth · Weight = Volume × Density.

Typical loose densities: pea gravel ≈ 1.4–1.5 t/m³ · crushed stone ≈ 1.5–1.7 t/m³ · compacted +10%.
