Introduction
The Pea Gravel Calculator helps you figure out how much pea gravel you need for your project. Whether you're making a walkway, filling a garden bed, or covering a driveway, this tool tells you exactly how much material to buy.
Pea gravel is small, smooth stones about the size of a pea. People use it for paths, patios, and decorative areas because it looks nice and drains water well. Getting the right amount matters - too little means extra trips to the store, and too much wastes money.
This calculator works for different shapes like rectangles, circles, and triangles. Just enter your area size and how deep you want the gravel. The tool then shows you how many tons, cubic yards, or bags you need. It also figures out the total cost including delivery and taxes. You can even see how many wheelbarrow loads or truck trips it will take to move all that gravel. For similar material calculations, try our River Rock Calculator or Concrete Calculator.

What is Pea Gravel?
Pea gravel is a type of small, rounded stone that looks like little peas. Each stone is about the size of a pea, usually between 1/8 inch to 3/8 inch wide. These smooth stones come in many colors like tan, brown, white, and gray. People use pea gravel for driveways, walkways, gardens, and play areas because it looks nice and drains water well.
How to Use Pea Gravel in Your Project
When you plan to use pea gravel, you need to know how deep to spread it. For decoration around plants, 1 to 2 inches deep works well. For walkways where people walk, use 2 to 3 inches. Driveways need 3 to 4 inches because cars are heavy. Areas with lots of traffic need 4 to 6 inches to stay strong and last longer. If you're working on a driveway project, you might also need our Asphalt Calculator to compare material options.
