Pea Gravel FAQs
Q: How deep should pea gravel be for a walkway or patio?
The optimal depth for a pea gravel walkway or patio is 2.5 to 3.0 inches. Depths greater than 3 inches feel spongy, causing your feet to sink, while depths under 2 inches will expose the landscape fabric or bare ground beneath.
Q: How much does a cubic yard of pea gravel weigh?
A cubic yard of pea gravel weighs approximately 1.40 US tons (2,800 lbs or 1,270 kg).
Q: How many bags of pea gravel cover 100 square feet?
At a standard 3-inch depth, 100 square feet requires 25 cubic feet of pea gravel, which equals 50 standard retail bags (0.5 cubic feet each) or approximately 0.93 cubic yards (1.3 US tons).
