How Many Cubic Feet in a Yard of Gravel?

If you are planning a landscaping or construction project, you may wonder: how many cubic feet in a yard of gravel?

The exact answer is:

$1\text{ cubic yard}=27\text{ cubic feet}$ 1 cubic yard=27 cubic feet

This conversion applies to all bulk materials, including:

Gravel
Sand
Soil
Mulch
Concrete

Understanding cubic yard conversions helps you:

Estimate material needs
Avoid overordering
Save money
Plan delivery sizes accurately

In this guide, you will learn how many cubic feet are in a yard of gravel, how gravel coverage works, project examples, weight estimates, and practical formulas for calculating gravel volume.

Quick Answer

One cubic yard of gravel contains:

$27\text{ cubic feet}$ 27 cubic feet

Exact Conversion

A cubic yard measures:

$3\text{ feet}\times3\text{ feet}\times3\text{ feet}$ 3 feet×3 feet×3 feet

Multiply those dimensions:

$3\times3\times3=27$ 3×3×3=27

Final result:

27 cubic feet

Why It Matters

Gravel is typically sold by:

Cubic yard
Ton
Truckload

Knowing cubic-foot conversions makes it easier to estimate:

Driveway projects
Landscaping jobs
Drainage systems
Garden paths

Understanding Cubic Yards and Cubic Feet

Before calculating gravel needs, it helps to understand these measurements.

What Is a Cubic Yard?

A cubic yard is a volume measurement equal to:

3 feet long
3 feet wide
3 feet high

Volume:

$27\text{ cubic feet}$ 27 cubic feet

What Is a Cubic Foot?

A cubic foot is:

1 foot long
1 foot wide
1 foot high

It represents a much smaller volume.

How to Convert a Yard of Gravel Into Cubic Feet

The conversion formula is simple.

Conversion Formula

Use:

$\text{Cubic Yards}\times27=\text{Cubic Feet}$ Cubic Yards×27=Cubic Feet

Step-by-Step Example

Suppose you order:

2 cubic yards of gravel

Gravel Coverage Chart

Coverage depends on gravel depth.

Coverage by Depth

One cubic yard of gravel covers approximately:

Depth	Coverage Area
1 inch	324 sq ft
2 inches	162 sq ft
3 inches	108 sq ft
4 inches	81 sq ft
6 inches	54 sq ft

Thicker layers cover less surface area.

Common Landscaping Uses

Different projects use different gravel depths.

Typical recommendations:

Walkways: 2–3 inches
Driveways: 4–6 inches
Drainage systems: 6+ inches

How Much Does a Yard of Gravel Weigh?

Weight varies based on gravel type and moisture content.

Average gravel weight:

$2,400\text{ to }3,000\text{ pounds per cubic yard}$ 2,400 to 3,000 pounds per cubic yard

Gravel Type Differences

Different gravel materials include:

Crushed stone
Pea gravel
River rock
Limestone

Some are denser than others.

Moisture Effects

Wet gravel weighs more because water adds mass.

This affects:

Delivery limits
Truck capacity
Transportation costs

Real-World Gravel Project Examples

Driveways

Suppose your driveway measures:

$20\text{ feet}\times40\text{ feet}$ 20 feet×40 feet

Area:

$20\times40=800\text{ square feet}$ 20×40=800 square feet

At 4 inches deep, you may need approximately:

10 cubic yards of gravel

Walkways

A garden path may only require:

1–2 cubic yards

depending on width and depth.

Drainage Areas

French drains often require:

Deep gravel layers
Multiple cubic yards

for proper water flow.

Common Gravel Calculation Mistakes

Many homeowners underestimate gravel needs.

Ignoring Depth

Depth significantly changes material requirements.

A shallow decorative layer uses far less gravel than a driveway base.

Confusing Square Feet With Cubic Feet

Square feet measure:

Surface area

Cubic feet measure:

Volume

Both dimensions matter.

Forgetting Compaction

Gravel settles over time.

Many contractors order:

5%–10% extra material

to account for compaction and waste.

Tips for Ordering Gravel

Measure Carefully

Record:

Length
Width
Desired depth

before ordering.

Convert Inches to Feet

If depth is measured in inches:

$\frac{\text{Inches}}{12}=\text{Feet}$ 12Inches=Feet

Example:

4 inches = 0.33 feet

Order Slightly Extra

Extra gravel helps avoid:

Delivery delays
Coverage shortages
Uneven surfaces

Why Gravel Is Sold by the Cubic Yard

Bulk materials are sold by volume because:

Shapes vary
Pieces are irregular
Weight changes with moisture

Volume provides more consistent pricing and estimating.

Visualizing One Cubic Yard of Gravel

One cubic yard is roughly equal to:

A cube measuring 3 feet on every side
About the size of a large household appliance

It may look smaller than expected until spread across a surface.
