Get precise weight and volume estimates for your driveway, pathway, or French drain. Compare tons vs. cubic yards instantly.
Quick Answer: To calculate gravel, multiply Length × Width × Depth to get cubic feet. Divide by 27 to get cubic yards. Multiply cubic yards by the gravel density (approx. 1.25 to 1.4 tons per cubic yard) to get the weight in tons. Always add 10% for compaction and waste.
Planning a landscaping project involves many variables, but none are as critical as the crushed stone calculator. Whether you're resurfacing a long country driveway or building a drainage solution with French drains, our gravel tonnage tool ensures you purchase the exact amount of material required. Eliminating guesswork saves hundreds of dollars in unnecessary transport fees and preventing mid-project material shortages.
If you prefer to run the numbers yourself, here is the standard formula used by contractors:
For a standard driveway gravel volume estimation, you typically need to plan for two or three layers of material. The base layer usually consists of larger crushed rock (around 2-3 inches), followed by a middle layer of smaller aggregate (3/4 inch minus), and finally a top dressing of decorative stone or clean gravel. When using our gravel requirement tool, remember to calculate each layer separately if the stone types differ. A standard residential driveway should have a total depth of at least 6 to 8 inches for stability.
Use this quick reference table to understand how much space a ton of different gravel types will cover at various depths.
| Gravel Type | Density (tons/yd³) | Coverage (1" depth) | Coverage (2" depth) | Typical Use |
|---|---|---|---|---|
| Crushed Stone | ~1.25 | ~320 sq ft | ~160 sq ft | Driveway base, drainage |
| Pea Gravel | ~1.20 | ~330 sq ft | ~165 sq ft | Walkways, playgrounds |
| River Rock | ~1.40 | ~280 sq ft | ~140 sq ft | Decorative borders, dry creeks |
| Lava Rock | ~1.10 | ~360 sq ft | ~180 sq ft | Lightweight landscaping |
Getting the depth right is crucial for a stable driveway. Here is the recommended layering:
| Layer | Material Type | Recommended Depth |
|---|---|---|
| Base Layer | #3 Crushed Stone (2-3") | 4 inches |
| Middle Layer | #57 Crushed Stone (3/4") | 2-3 inches |
| Top Layer | Pea Gravel or Crush & Run | 1-2 inches |
The term "ton" can be misleading because different rock types have varying gravel density. For example, river rock quantity requirements will weigh more per cubic yard than porous lava rock. Our pea gravel estimator defaults to the industry average of 2,400 to 2,800 pounds per cubic yard. When you order from a quarry, they will likely give you a price "per ton at the scale." Knowing your gravel coverage per ton helps you communicate effectively with suppliers and ensures your delivery truck has the right capacity.
Material costs can vary significantly based on your location and the type of stone you choose. As a general rule of thumb in 2026:
Our calculator includes a "Cost per Ton" input so you can instantly estimate your total material budget for bulk orders. Don't forget to factor in delivery fees, which can range from $50 to $150 depending on your location and order size.
A single cubic yard of gravel is equivalent to about 50 to 55 bags (50lb each) from a home improvement store. For any area larger than a small decorative border, quarry stone estimator results will show that bulk delivery is the only logical choice. A standard dump truck can carry between 10 and 20 tons of gravel, making it the most efficient way to handle large-scale driveway gravel volume projects.
Our calculator gives you the material estimate. Now connect with local gravel and aggregate suppliers for the best bulk pricing.

A: Most gravel and crushed stone weigh approximately 1.25 to 1.4 tons per cubic yard, depending on the rock size and moisture.
Q: What is the best depth for a gravel driveway?
A: For a new driveway, 8 inches of total depth is recommended (spread over 3 layers). For a refreshed surface, 2 to 4 inches is usually sufficient.
Q: How much does a ton of gravel cost in 2026?
A: As of 2026, bulk gravel costs range from $25 to $60 per ton depending on the type of stone and your location. Decorative stones like river rock can cost upwards of $100 per ton.
Q: Does gravel compact over time?
A: Yes, especially "crush and run" or "3/4 inch minus" gravel. You should always order 10% extra to account for compaction and settling into the subsoil.
Q: How do I prevent weeds from growing through my gravel path?
A: Use a high-quality landscape fabric (geotextile) beneath the gravel layer. This allows water to drain but blocks weed roots from reaching the soil.
