Frequently Asked Questions
How much gravel do I need?
Multiply the length by the width of your project area to get square feet, then multiply by the depth in feet to get cubic feet. Divide by 27 to get cubic yards. A typical driveway layer is 3–4 inches deep; a walkway or patio base is usually 2–3 inches. Gravel Wiz does all of this math for you instantly.
How many tons is a cubic yard of gravel?
A cubic yard of gravel typically weighs 1.35 to 1.45 US tons (2,700–2,900 lbs) depending on the material. Crushed stone averages about 1.4 tons per cubic yard, pea gravel about 1.45, and river rock about 1.35.
How deep should a gravel driveway be?
A gravel driveway is usually built in two or three layers totaling 8–12 inches: a 4-inch base of larger crushed stone, an optional middle layer, and a 3–4 inch top layer of smaller gravel. For a simple refresh of an existing driveway, a 2–3 inch top-up is common.
Should I order extra gravel?
Yes — most contractors order 5–10% more than the calculated amount to account for compaction, settling, uneven ground, and spillage. Gravel compacts when driven on or tamped, so a little extra avoids a second delivery fee.
How much does gravel cost?
Bulk gravel typically costs $15–$75 per ton depending on the type and your location, plus delivery. Crushed stone and drainage rock sit at the lower end, while decorative river rock and specialty stone cost more. Enter your local price per ton in the calculator to estimate your total.
