Gravel Calculator
Calculate gravel quantities and costs for your project
Our gravel calculator helps you determine the amount of gravel needed for your project. Follow these steps:
- Enter the length and width of your area in feet
- Specify the desired depth in inches
- Select your gravel type (density)
- Enter the price per ton of gravel
The calculator will provide the area, volume, weight, and estimated cost of the gravel needed.
Common gravel types and their typical uses:
- Pea Gravel (1.4-1.5 tons/yd³): Walkways, patios, playgrounds
- Crushed Stone (1.4-1.6 tons/yd³): Driveways, drainage
- River Rock (1.3-1.5 tons/yd³): Landscaping, water features
- Base Gravel (1.5-1.7 tons/yd³): Foundation, road base
- Decomposed Granite (1.3-1.4 tons/yd³): Pathways, landscaping
- Drainage Gravel (1.4-1.6 tons/yd³): French drains, drainage systems
Recommended gravel depths for different applications:
- Walkways: 2-3 inches
- Residential Driveways: 4-6 inches
- Commercial Driveways: 8-12 inches
- Landscaping: 2-4 inches
- French Drains: 8-12 inches
- Parking Areas: 6-8 inches
- Road Base: 6-12 inches
- Playground Areas: 3-4 inches
- Prepare the site by removing vegetation and topsoil
- Install proper edging to contain the gravel
- Use landscape fabric to prevent weed growth
- Ensure proper drainage slope (minimum 1%)
- Compact base material before adding gravel
- Add gravel in layers for better compaction
- Consider traffic patterns when choosing depth
- Plan for periodic maintenance and top-ups
How much gravel do I need for a driveway?
For a typical residential driveway, use 4-6 inches of gravel depth. The calculator will help you determine the exact amount based on your driveway dimensions.
What affects gravel density?
Gravel density varies by stone type, size, and shape. Angular stones typically have higher density than rounded ones, and larger stones may have more void space between them.
Should I order extra gravel?
Yes, it's recommended to order 5-10% extra gravel to account for compaction, uneven ground, and potential miscalculations. This ensures you have enough material to complete your project.
