What Is a Pea Gravel Calculator?

A pea gravel calculator estimates volume, weight, bag count, and cost for landscaping projects. Pea gravel is small, rounded stone used on pathways, patios, drainage trenches, and decorative borders. Enter area dimensions and depth to plan material delivery.

How Much Pea Gravel Do I Need?

Volume from length, width, and depth:

$$\text{volume} = \text{length} \times \text{width} \times \text{depth}$$

Weight from pea gravel density (about 111.6 lb/ft³):

$$\text{weight} = \text{volume} \times \text{density}$$

Recommended depths vary by use: 2 to 3 inches for pathways and patios, 3 to 4 inches for driveways, and 6 inches or more for drainage. Compare with the Gravel Calculator and French Drain Calculator for related aggregate projects.

Frequently Asked Questions

How much does 5 cubic feet of pea gravel weigh?

Five cubic feet of pea gravel weighs about 558 lb at a typical density of 111.6 lb/ft³. A full cubic yard weighs close to 3,000 lb, so bulk delivery often needs a truck.

How many bags of pea gravel do I need?

Divide your total volume in cubic feet by the bag size. Most decorative stone bags hold about 0.5 cubic feet. A 12 cubic foot project needs roughly 24 bags.

Is pea gravel good for drainage?

Yes. Rounded pea gravel leaves gaps between stones so water flows freely. It works well in French drains, trench beds, and permeable landscaping layers.

What depth of pea gravel should I use for a patio?

Most patios use 2 to 3 inches of pea gravel for a comfortable walking surface. Driveways and load-bearing areas need 3 to 4 inches or more.

How much does pea gravel cost per yard?

Bulk pea gravel often costs $25 to $65 per cubic yard depending on region and delivery. Bagged material costs more per unit, so bulk delivery is usually cheaper for larger projects.
