Pea Gravel Calculator

One ton of pea gravel covers about 100 square feet at 2 inches deep; a cubic yard covers 162 square feet at that depth.

Pea gravel is rounded 3/8-inch stone sold loose by the ton or bagged by the half cubic foot. Two inches is enough for beds and paths; play areas and patios usually want three.
