- Set your desired gravel depth (2-4 inches is typical for most projects)
- Choose the type of gravel or enter a custom density
- Optionally add pricing to estimate total project cost
Recommended Gravel Depth by Project
The ideal gravel depth varies depending on your specific application. Here are general recommendations to ensure durability and proper drainage.
- Driveways: 4-6 inches for proper vehicle support
- Walkways: 2-3 inches for foot traffic
- Patios: 3-4 inches with proper compaction
- Landscaping: 2-3 inches for decorative coverage
- Drainage areas: 4-6 inches for optimal water flow
Frequently Asked Questions
For a typical driveway, you'll need approximately 1.5 cubic yards per 100 square feet at a 4-inch depth. For example, a 12ft x 50ft driveway (600 sq ft) would need about 9 cubic yards of gravel. Use our calculator above for precise measurements based on your specific dimensions.
Cubic yards measure volume while tons measure weight. The conversion depends on the gravel type and density. Generally, 1 cubic yard of gravel weighs between 1.3 to 1.5 tons. Our calculator automatically converts between volume and weight based on the gravel type you select.
Yes, it's recommended to order 5-10% more gravel than calculated. This accounts for spillage, settling, compaction, and irregular ground surfaces. For projects with significant slopes or uneven terrain, consider ordering 15% extra.
For driveways, crushed stone or gravel with angular edges (like #57 stone) works best because it interlocks and compacts well. A layered approach using larger base gravel (3-4 inches) topped with smaller surface gravel provides the most stable and long-lasting surface.
