How to Calculate Pea Gravel for Landscaping
Pea gravel is a popular choice for decorative paths, garden borders, and play areas. Because of its small, rounded nature, getting the right depth and calculating the proper volume is critical. Our Pea Gravel Calculator turns your project dimensions into an exact estimate of cubic yards and individual bags needed.

Pea Gravel Formulas
- 1) Volume RequirementsArea = Length × Width
Volume = Area × Depth - 2) Weight EstimationPea Gravel Density ≈ 100 lb / cubic foot
Weight = Volume (Cubic Feet) × 100 - 3) Bag CalculationTotal Bags = Total Weight ÷ Weight per Bag
Frequently Asked Questions
How much pea gravel do I need?
Measure your landscaping area and input it along with a standard 2-3 inch depth into our calculator to determine the required cubic yards, bags, and tonnage.
How deep should pea gravel be for landscaping?
For most garden beds and weed prevention over landscape fabric, 2 to 3 inches is ideal. For frequently walked paths, 2.5 inches gives a solid feel while avoiding loose slipping.
How many bags of pea gravel do I need?
A typical 0.5 cubic foot bag of pea gravel weighs about 50 lbs. If you need 1 cubic yard (which is 27 cubic feet), you would need 54 of these bags.
Is pea gravel sold by yard or ton?
Bulk pea gravel is traditionally sold by the cubic yard or ton at local soil/aggregate yards. For smaller projects, it is sold by the bag at home improvement stores.
