Gravel Calculator.
Estimate gravel volume and weight for driveways, paths, and landscaping. Get cubic yards and tons from length, width, and depth.
Why Use a Gravel Calculator?
Ordering too little gravel means another delivery; ordering too much wastes money. This free gravel calculator converts your area and depth into cubic yards and tons so you can order the right amount for driveways, walkways, and beds.
How to Calculate Gravel Volume
Convert depth from inches to feet by dividing by 12. Then multiply cubic yards by density (about 1.4 tons per yd³ for typical gravel) to estimate weight.
Frequently Asked Questions (FAQs)
How do I calculate how much gravel I need?
Multiply length × width × depth (same units) for volume. Convert to cubic yards (÷ 27 from cubic feet), then multiply by density (~1.4 tons/yd³) for weight.
How deep should gravel be for a driveway?
Most gravel driveways use 4–6 inches of base gravel. Footpaths often need 2–3 inches. Add a little extra for compaction.
How many tons are in a cubic yard of gravel?
Dry gravel typically weighs about 1.4 tons (~2,800 lbs) per cubic yard. Confirm density with your supplier.
