How Much Does 5 Cubic Feet of Pea Gravel Weigh?

Key Takeaways:

• Most pea gravel weighs 100 – 125 pounds per cubic foot.
• With a density of 110 pounds per cubic foot on average, 5 cubic feet of pea gravel weighs about 550 pounds.
• Weight per cubic foot varies slightly based on pea gravel type, moisture content, compaction, and size grading.
• Measuring width x length x depth and multiplying by 110 pounds estimates pea gravel weight in any space.

Understanding Pea Gravel Density

Pea gravel consists of small, naturally rounded rock fragments typically under 5/8″ in diameter. It is extracted from river beds or crushed from larger rocks in quarries. The smooth oval pebbles resemble green peas.

Pea gravel weighs 110 pounds per cubic foot on average. But density ranges from 100 – 125 lbs/ft3 depending on its composition and structure. Knowing pea gravel’s weight per cubic foot helps estimate amounts required for landscaping projects.

Since pea gravel is sold by the cubic yard or ton, you can calculate approximate weight and quantity needs based on project dimensions. 5 cubic feet equates to about 1/3 of a cubic yard. With pea gravel density at 110 lbs/ft3, 5 cubic feet weighs approximately 550 pounds.

Factors Affecting Weight

Several factors cause pea gravel density and weight per cubic foot to vary:

• Composition – Limestone pea gravel is heavier at 125 lbs/ft3 vs. lighter volcanic gravel at 100 lbs/ft3.
• Size distribution – A wider mix of rock sizes packs more densely than a narrow size range.
• Moisture content – Dry pea gravel weighs less than wet material.
• Compaction – Tightly compacted pea gravel concentrates particles and increases density.
• Measurement – Estimating origins like loose dump truck beds affects cubic foot accuracy.

Since these factors differ across suppliers and locations, request current density test data to dial in weight estimates. Testing your actual pea gravel is best.

With pea gravel’s bulk density around 110 pounds per cubic foot, you can easily convert between weight and volume for planning purposes using this average. Contact us to order pea gravel and other bulk landscaping aggregates.
