Formula & assumptions

How the pea gravel calculator works

Volume = length × width × depth. Cubic yards = cubic feet ÷ 27. Tons = cubic yards × selected density.

For a better estimate

Measure depth after deciding whether the gravel is decorative or structural.
Use landscape edging where needed to reduce migration.
Density is approximate; supplier values are best for ordering by weight.
