Pea Gravel: Coverage, Depth & Uses
Pea gravel is smooth, rounded ⅜″ stone commonly used for patios, paths, play areas, dog runs, and drainage. One cubic yard weighs about 2,700–2,800 lb and covers approximately 100 sq ft at a 3″ depth. For walkable surfaces, use a 2–3″ layer and edging to keep the gravel contained.
