How it works
Calculate your material requirement
Estimate gravel volume, cubic yards, and tons for driveways, paths, patios, and landscaping projects.
The formula
Cubic yards = length × width × (depth ÷ 12) ÷ 27. Estimated tons = cubic yards × material density.
Worked example
A 20 ft × 10 ft area at 3 in deep is 1.85 yd³ before waste. With 10% extra and a density of 1.4 tons/yd³, the order estimate is about 2.85 tons.
Before you order
- Compacted base gravel is commonly ordered by weight.
- Ask the supplier for the actual density of the product you selected.
- Irregular areas can be divided into rectangles and added together.
