Gravel & Stone Calculator

Free Gravel & Stone Calculator to estimate cubic yards, tons, coverage area, and material costs for gravel, crushed stone, pea gravel, river rock, limestone, and sand.

How Much Gravel Do You Need?

Whether you're building a driveway, creating a walking path, installing drainage, or landscaping a yard, estimating the correct amount of gravel or stone is essential. Ordering too little can delay your project, while ordering too much increases costs and waste.

This Gravel & Stone Calculator estimates cubic feet, cubic yards, tons, and project cost based on your measurements and selected material type.

Gravel Coverage Formula

Cubic Feet = Length × Width × (Depth ÷ 12)

Cubic Yards = Cubic Feet ÷ 27

Estimated Tons = Cubic Yards × Material Density

Gravel Weight & Density Guide

  • Material: Gravel
    Approximate Tons Per Cubic Yard: 1.40

  • Material: Crushed Stone
    Approximate Tons Per Cubic Yard: 1.50

  • Material: Pea Gravel
    Approximate Tons Per Cubic Yard: 1.35

  • Material: River Rock
    Approximate Tons Per Cubic Yard: 1.40

  • Material: Limestone
    Approximate Tons Per Cubic Yard: 1.45

  • Material: Sand
    Approximate Tons Per Cubic Yard: 1.35

Different materials have different densities, which is why the estimated tonnage varies even when the volume remains the same. Crushed stone is generally heavier than pea gravel, while sand and decorative rock often fall somewhere in between.

Understanding density helps ensure accurate ordering and reduces the chance of running short on material during installation.

Gravel vs Crushed Stone

Although gravel and crushed stone are often used interchangeably, they serve different purposes.

Gravel

  • Rounded edges

  • Better appearance for landscaping

  • Improved drainage

  • Common for pathways and decorative applications

Crushed Stone

  • Angular edges

  • Compacts more effectively

  • Excellent for driveways and foundations

  • Provides greater stability under heavy loads

For driveways and structural applications, crushed stone is often preferred. For landscaping and decorative projects, gravel and river rock are popular choices.

Ordering Gravel & Delivery Tips

Most suppliers sell gravel, stone, and sand by the ton or cubic yard. Before ordering:

  • Measure carefully

  • Verify delivery access

  • Consider compaction and settling

  • Order 5%–10% extra material

  • Confirm supplier tonnage calculations

Many contractors recommend slightly overestimating material needs rather than risking shortages during installation.

Gravel & Stone Calculator FAQ

How many tons of gravel do I need?
Multiply cubic yards by the material density. Most gravel weighs approximately 1.4 tons per cubic yard.

How many square feet does a ton of gravel cover?
Coverage depends on material depth. Shallower depths cover larger areas while deeper installations cover less area.

Should I buy gravel by the ton or cubic yard?
Many suppliers price gravel by the ton because weight provides a more accurate measurement than loose volume.

What is the best gravel for a driveway?
Crushed stone is often preferred because its angular shape compacts well and provides excellent stability.

How deep should gravel be?
Most pathways use 2–4 inches of gravel, while driveways often require 4–6 inches or more depending on use.
