Gravel Density Chart
Different aggregates have vastly different weights. Use this reference chart to understand how material choice impacts your total tonnage requirements:
| Material Type | Average Density (lb/ft³) | Tons per Cubic Yard |
|---|---|---|
| Standard Gravel | 105 lb/ft³ | ~1.42 Tons |
| Crushed Stone (Clean) | 100 lb/ft³ | ~1.35 Tons |
| Pea Gravel | 105 lb/ft³ | ~1.42 Tons |
| River Rock | 110 lb/ft³ | ~1.48 Tons |
| Construction Sand | 100 lb/ft³ | ~1.35 Tons |
| Crushed Limestone | 95 lb/ft³ | ~1.28 Tons |
| Crusher Run (with fines) | 120 lb/ft³ | ~1.62 Tons |
Introduction
Whether you're planning a massive commercial parking lot or a simple residential fire pit, our Gravel Calculator is designed to help you instantly estimate how much gravel, crushed stone, river rock, sand, or aggregate you need. Accuracy is critical in landscaping and construction: under-estimating your material results in costly project delays and secondary delivery fees, while over-estimating wastes your project budget on material you don't need.
Using advanced volumetric conversion algorithms, this tool calculates cubic yards, tons required, approximate truckloads, and local material costs for driveways, patios, walkways, French drains, and foundations. Simply enter your dimensions, select a material type to apply its specific density, and let the calculator do the heavy lifting.
How to Use the Gravel Calculator
Our gravel yardage calculator eliminates the guesswork from your material ordering process. Follow these simple steps to calculate your exact aggregate needs:
- Select your project type: Choosing between a driveway, walkway, or patio helps you conceptualize the space, though the core mathematical volume remains length × width × depth.
- Enter the Length and Width: Measure the longest side and the widest side of your project area. You can input measurements in feet, inches, yards, or meters.
- Enter the desired Depth: Depth is crucial. A standard walkway may only need 2 inches of pea gravel, whereas a heavy-duty driveway base might require 6 inches of crusher run.
- Select your Material Type: Not all rock weighs the same. Sand is lighter than solid limestone. Our calculator dynamically adjusts the density (lb/ft³) based on whether you select River Rock, Pea Gravel, Crushed Stone, or Road Base.
- Adjust the Waste Factor: Construction best practices dictate adding a 10% waste margin. This accounts for spillage, compaction settling, and uneven ground grades.
- Enter Local Costs: Call your local quarry to get the current price per ton, enter it into the tool, and instantly see your estimated total material cost.
Gravel Volume Formula Explained
The foundation of any crushed stone estimate is calculating the cubic volume of the space you intend to fill. The formula is standard geometric volume:
Once the total cubic feet are established, our calculator automatically divides by 27 to find the Cubic Yards, which is the standard unit of measurement used by commercial quarries and landscape supply yards.
Gravel Weight Formula
Because rock is sold by weight (tons) rather than pure volume, calculating the tonnage is the final and most important step.
Standard gravel has an average density of 105 pounds per cubic foot. Therefore, one cubic yard (27 cubic feet) of standard gravel weighs approximately 2,835 lbs, or 1.42 tons.
Gravel Calculator for Driveways
Building a durable gravel driveway requires careful planning and the right materials. A typical residential gravel driveway needs a minimum depth of 4 to 6 inches to support the weight of passenger vehicles without rutting. For the base layer, contractors typically use larger angular stones like #3 crushed stone, topped with a binding layer like Crusher Run or #57 stone.
Use our driveway gravel calculator to determine exactly how many tons of base and top-coat material you need to order to ensure proper compaction and longevity.
Common Gravel Applications
Paths experience less weight than driveways, requiring only 2-3 inches of depth. Remember to factor in a weed barrier and rigid edging to contain loose stones.
A cost-effective alternative to poured concrete. Using crushed stone with "fines" (stone dust) allows it to compact tightly, creating a stable surface for furniture.
Use highly porous, washed aggregate (like 1.5" river rock) to allow water flow. Never use stone with fines, as the dust will clog the pipe perforations.
Gravel Coverage Chart
A quick reference guide for how much area a single Cubic Yard of gravel will cover at various depths:
- 324 sq ft coverage at a 1-inch depth
- 162 sq ft coverage at a 2-inch depth
- 108 sq ft coverage at a 3-inch depth
- 81 sq ft coverage at a 4-inch depth (Standard Patio)
- 54 sq ft coverage at a 6-inch depth (Standard Driveway)
Gravel Cost Estimator
Material costs fluctuate based on geographic location, proximity to local quarries, and the type of aggregate required. Below are national average costs for raw materials:
- Pea Gravel: $30 - $70 per ton (Popular for playgrounds and walkways)
- Crushed Stone (#57): $20 - $50 per ton (Standard utility rock)
- River Rock: $50 - $120 per ton (Premium decorative aggregate)
- Crushed Limestone: $25 - $60 per ton (Excellent compacting base)
Important Cost Note
The prices generated by our calculator represent raw material costs. They typically exclude delivery charges. Delivery fees often range from $50 to $150 per truckload depending on the distance from the quarry. Additionally, many suppliers enforce a "minimum tonnage" fee for orders under 3 to 5 tons.
Common Gravel Project Examples
To help you estimate, here are common dimensions for standard landscaping and construction projects:
- Small Garden Walkway: 20 ft Length × 3 ft Width × 3 inches Depth
- Single-Car Residential Driveway: 40 ft Length × 12 ft Width × 4 inches Depth
- Backyard Gravel Patio: 15 ft Length × 15 ft Width × 4 inches Depth
- Foundation French Drain: 50 ft Length × 1 ft Width × 12 inches Depth
Frequently Asked Questions
How much gravel do I need?
Measure the length, width, and depth of your project area. Multiply these dimensions together to find the total volume.
How many tons of gravel do I need?
After calculating the cubic volume, multiply by the density of the gravel (typically 105 lbs per cubic foot) and convert to tons.
How much does a cubic yard of gravel weigh?
A cubic yard of standard gravel weighs approximately 2,800 to 2,900 pounds, or about 1.4 to 1.45 tons.
What is the best gravel for driveways?
Crusher run or #57 crushed stone are ideal for driveways because the angular edges interlock and form a solid base.
How deep should driveway gravel be?
A standard residential gravel driveway requires a minimum depth of 4 to 6 inches.
How much does gravel cost per ton?
Gravel typically costs between $30 and $70 per ton depending on the type and location, excluding delivery.
How many cubic yards are in a ton of gravel?
One ton of gravel is approximately 0.71 cubic yards.
Can I use this calculator for sand and crushed stone?
Yes. You can select different material types like sand, pea gravel, or crushed stone, and the calculator will automatically adjust the density.
