Variables:
Worked Examples
20×30 ft driveway, 3 inches deep
- 1. Volume = (20 × 30 × 3/12) ÷ 27 = 5.56 cu yd
- 2. Tons = 5.56 × 1.4 = 7.78 tons
10×40 ft path, 2 inches deep
- 1. Volume = (10 × 40 × 2/12) ÷ 27 = 2.47 cu yd
- 2. Tons = 2.47 × 1.4 = 3.46 tons
Why Use This Calculator
- Avoid expensive over-ordering or project delays from under-ordering.
- Converts between cubic yards and tons for accurate ordering.
- Works for driveways, paths, landscaping beds, and drainage projects.
- Includes cost estimate based on local average pricing.
Tips & Best Practices
- Order 10% extra for settling and edge loss.
- Use 2-3 inches for walkways, 3-4 inches for driveways.
- Compact gravel in layers for best stability.
- Consider a weed barrier fabric underneath for low-maintenance results.
Common Mistakes to Avoid
❌ Using depth in feet instead of inches.
✅ Gravel depth is typically 2-4 inches. Make sure you enter inches, not feet.
❌ Not accounting for settling over time.
✅ Fresh gravel settles 10-15%. Order extra to maintain desired final depth.
