Gravel Calculator
Estimate gravel volume in cubic yards for paths and bases.
Use decimals when needed. This estimate updates live and is safe to tweak before you buy materials.
Gravel Buying Guide
This guide helps you turn your gravel calculator result into a cleaner purchase plan. Use it when you want fewer return trips, better waste assumptions, and a more realistic cart.
Step 1: Pick the right stone
Pea gravel is great for walkways but terrible for driveways because it shifts. Use crushed stone with jagged edges (like #57 stone or crusher run) for areas that need to compact.
Step 2: Convert volume to weight
While you measure the area in cubic yards, quarries sell gravel by the ton. A cubic yard of standard crushed stone weighs roughly 1.4 tons.
Step 3: Lay down fabric first
Always install heavy-duty, woven landscape fabric under the gravel. It stops weeds from growing up and prevents your expensive gravel from sinking into the mud.

Gravel cost planning rule of thumb
Budget for the gravel, delivery fees, heavy-duty weed barrier fabric, and steel landscape pins to hold the fabric down.
Understanding the Math
Formula: The basic formula for Gravel Calculator typically involves calculating the total area or volume (Length × Width × Depth) and dividing by the coverage of a single unit or package, then adding a waste factor (usually 10%).
Example: For example, if you have a 10x10 area and your material covers 10 square feet per unit, you need 10 units. With a 10% waste factor, you should purchase 11 units to ensure you don't run short.
