Understanding Gravel Calculations
The core of any gravel calculation involves three simple measurements. Our calculator handles all the complex math for you!
Dimensions
-
Length & Width: Measure the two sides of your rectangular area in feet.
-
Radius: For circular areas, measure from center to edge.
Depth
Decide how deep you want your gravel layer (measured in inches):
Calculation
From Volume to Weight (Tons)
Gravel is almost always sold by weight (tons). Different types of gravel have different densities—some are heavier than others. Our tool stores the average density for common gravel types and converts the volume into the total weight you'll need to order.
Always add 5-10% extra to your final amount for compaction, settling, and minor waste during installation.

Your Step-by-Step Gravel Driveway Guide
Building a professional gravel driveway is a rewarding project. Follow these proven steps for a durable result that will last for years.
Planning & Calculation
Measure twice, order once.
Start by marking out your driveway's dimensions with stakes and string. Our tool is more than just a simple gravel calculator; it's a comprehensive driveway gravel calculator that removes the guesswork. It functions as a cubic yard calculator for gravel and a gravel ton calculator, giving you the precise volume and weight needed. By using it as a cost of gravel driveway calculator, you can budget effectively before you begin.
Excavation
Create a solid foundation.
Dig out the entire area to the recommended depth. For a durable drive, an excavation of 8 to 12 inches is crucial. This step prevents the gravel from sinking into the soil and ensures your driveway remains stable through all seasons. Remove all vegetation, roots, and organic matter.
Rent a mini excavator for large areas. Check for underground utilities before digging!
Base Layer & Materials
Choose the right stone.
Lay down landscape fabric to block weeds. For the base, the best gravel for driveway stability is a large, angular stone like #3 crushed stone or road base. Spread a 4-6 inch layer and compact it firmly with a plate compactor. This is the most important layer for your gravel for drives calculator estimates.
✅ Best Materials:
- • #3 Crushed Stone
- • Road Base Mix
- • Angular Aggregate
📏 Specifications:
- • 4-6 inch depth
- • Compact in 2" lifts
- • Proper drainage slope
Top Layer & Finishing
The final, visible surface.
Add a 3-4 inch middle layer of #57 crushed stone and compact it. For the top 2-3 inches, you can use a finer crushed stone or a decorative rock. While not ideal for a driveway's main surface, our pea gravel calculator can help if you're using it for adjacent decorative beds. Rake the surface smooth for a clean finish.
🎯 Finishing Checklist:
Long-Term Maintenance Tips
Rake Regularly
Smooth out ruts and redistribute gravel every few months to maintain appearance.
Control Weeds
Remove any weeds that appear promptly and apply pre-emergent herbicide annually.
Top Up Material
Add a fresh layer every 2-4 years to replace gravel lost to weather and traffic.
Frequently Asked Questions
How deep should my gravel be?
It depends on the project. For walkways and patios, 2-3 inches is enough. For a standard residential driveway, aim for 4-6 inches over a compacted base. For areas with heavy vehicle traffic, you might need 6-8 inches.
Do I need landscape fabric under my gravel?
Yes, it's highly recommended. Landscape fabric acts as a barrier that prevents weeds from growing up through your gravel and stops the stones from sinking into the soil below. It's essential for driveways and paths.
What is the difference between crushed stone and pea gravel?
Crushed stone is made of angular, machine-crushed rock. The sharp edges lock together, making it very stable and ideal for driveways and bases. Pea gravel consists of small, naturally weathered, rounded stones. It's more decorative and comfortable to walk on, making it perfect for paths, patios, and play areas.
How much does a cubic yard of gravel weigh?
A cubic yard of gravel typically weighs between 1.2 to 1.5 tons (2,400 to 3,000 lbs). The exact weight depends on the type of rock and how much moisture it contains. Our calculator uses average densities for its estimates.
