Planning a gravel project like a driveway, walkway, garden, or construction base? One of the most confusing parts is figuring out how much gravel you'll need. That's where our Gravel Yardage Calculator comes in. Whether you’re dealing with square feet, cubic yards, or tons, this tool helps you estimate the exact amount of gravel required saving time, money, and effort.

Whether you're laying 3/4 inch crushed stone for a driveway or building a concrete base, accurate yardage calculation is essential to avoid over- or under-ordering. This guide will show you exactly how to calculate gravel yardage and convert it to cubic yards or tons.

What is a Gravel Yardage Calculator?

A gravel yardage calculator is a digital tool that helps users estimate the volume of gravel they need for a specific area. It calculates the cubic yards or tons of gravel required based on your project’s length, width, and depth in feet or inches.

This calculator is perfect for home renovators, landscapers, and contractors who want to make smart purchasing decisions.

How to Use the Gravel Yardage Calculator

Using our gravel calculator is super simple. You just need to input the following:

  1. Length of the area (in feet)
  2. Width of the area (in feet)
  3. Depth (in inches)

The calculator then gives you:

  • Cubic yards of gravel required
  • Tons of gravel required (based on gravel type)

Formula to Calculate Gravel Yardage

Here’s the standard formula to calculate gravel in cubic yards:

Cubic Yards = (Length in feet × Width in feet × Depth in inches) ÷ 324

To convert cubic yards to tons, use:

Tons = Cubic Yards × Density factor (approx. 1.4 for 3/4 inch crushed stone)

Example: If you have a driveway that's 20 feet long, 10 feet wide, and you want 4 inches of gravel:

Cubic Yards = (20 × 10 × 4) ÷ 324 = 2.47 cubic yards

Tons = 2.47 × 1.4 = 3.46 tons
