If you’re planning a concrete project, you’ve probably heard concrete sold by the yard. This often leads to the question:
How many feet is in a yard of concrete?
The answer depends on whether you’re talking about linear feet or cubic feet:
- 1 yard (linear) = 3 feet
- 1 cubic yard of concrete = 27 cubic feet
Because concrete is measured by volume, contractors almost always mean cubic yards, not linear yards.
This guide explains the difference, shows how to convert between cubic yards and cubic feet, and provides practical examples for estimating concrete.
How Many Feet Is in a Yard of Concrete?
For concrete, the standard measurement is a cubic yard.
A cubic yard measures:
- 3 feet long
- 3 feet wide
- 3 feet high
Its volume is:
3 × 3 × 3 = 27 cubic feet
Quick Answer
| Measurement | Equivalent |
|---|---|
| 1 yard (linear) | 3 feet |
| 1 cubic yard of concrete | 27 cubic feet |
✔ Final Answer: A yard of concrete means 1 cubic yard, which equals 27 cubic feet.
Understanding Linear Yards vs. Cubic Yards
Linear Yard
A linear yard measures length only.
- 1 yard = 3 feet
This measurement is commonly used for:
- Fabric
- Landscaping materials
- Fencing
Cubic Yard
A cubic yard measures volume.
It represents a cube measuring:
- 3 feet × 3 feet × 3 feet
Concrete, gravel, sand, and mulch are typically sold by the cubic yard.
Formula for Converting Cubic Yards to Cubic Feet
Use this conversion:
Example
For 1 cubic yard:
1 × 27 = 27 cubic feet
Step-by-Step Calculation
Step 1: Know the Conversion
1 cubic yard = 27 cubic feet
Step 2: Multiply
For 2 cubic yards:
2 × 27 = 54 cubic feet
Final Result
- 1 cubic yard = 27 cubic feet
- 2 cubic yards = 54 cubic feet
- 5 cubic yards = 135 cubic feet
Why Is Concrete Sold by the Cubic Yard?
Concrete fills three-dimensional space, so it must be measured by volume, not just length.
For example, a concrete slab has:
- Length
- Width
- Thickness
All three dimensions determine how much concrete you need.
How to Calculate Concrete Needed
Measure:
- Length (feet)
- Width (feet)
- Thickness (feet)
Then calculate the volume:
Finally, convert cubic feet to cubic yards:
Example Calculation
Suppose you’re pouring a patio:
- Length = 12 ft
- Width = 10 ft
- Thickness = 4 inches
Convert thickness:
4 inches ÷ 12 = 0.333 feet
Calculate volume:
12 × 10 × 0.333 = 39.96 cubic feet
Convert to cubic yards:
39.96 ÷ 27 ≈ 1.48 cubic yards
You’ll typically order 1.5 cubic yards (or slightly more to allow for waste).
Cubic Yard Conversion Chart
| Cubic Yards | Cubic Feet |
|---|---|
| 1 | 27 cu ft |
| 2 | 54 cu ft |
| 3 | 81 cu ft |
| 4 | 108 cu ft |
| 5 | 135 cu ft |
| 10 | 270 cu ft |
Approximate Coverage of One Cubic Yard of Concrete
| Thickness | Coverage |
|---|---|
| 2 inches | 162 sq ft |
| 3 inches | 108 sq ft |
| 4 inches | 81 sq ft |
| 5 inches | 65 sq ft |
| 6 inches | 54 sq ft |
These figures are approximate and assume no waste.
Common Uses for One Cubic Yard of Concrete
A cubic yard of concrete can be used for:
- Small patios
- Sidewalk sections
- Shed foundations
- Fence post footings
- Driveway repairs
- Garden paths
Tips for Ordering Concrete
Measure Carefully
Accurate measurements help avoid shortages or excess material.
Add Extra
Order about 5–10% more concrete to account for spills, uneven ground, and finishing.
Consider Ready-Mix
For larger projects, ready-mix concrete delivered by truck is often more efficient than mixing bagged concrete.
Common Mistakes
Confusing Linear and Cubic Yards
Remember:
- Linear yard = 3 feet
- Cubic yard = 27 cubic feet
Forgetting Thickness
Concrete calculations require length × width × thickness.
Not Converting Inches
Always convert slab thickness from inches to feet before calculating volume.
Frequently Asked Questions
How many feet are in a yard of concrete?
A linear yard equals 3 feet, while one cubic yard of concrete equals 27 cubic feet.
Why is concrete measured in cubic yards?
Concrete fills volume, so it is measured in cubic yards, not linear feet.
How many cubic feet are in a cubic yard?
27 cubic feet.
How much area does one cubic yard cover?
Coverage depends on thickness. At 4 inches thick, one cubic yard covers approximately 81 square feet.
How do I convert cubic feet to cubic yards?
Divide the total cubic feet by 27.

Conclusion
The answer to “How many feet is in a yard of concrete?” depends on the type of measurement:
- 1 linear yard = 3 feet
- 1 cubic yard of concrete = 27 cubic feet
Since concrete is sold by volume, you’ll almost always use cubic yards when estimating a project.
Using the conversion:
you can quickly calculate the amount of concrete needed for slabs, patios, driveways, footings, and other projects.
Quick Reference
- 1 yard = 3 feet
- 1 cubic yard = 27 cubic feet
- Concrete is measured by volume
- 1 cubic yard covers about 81 square feet at 4 inches thick
- Divide cubic feet by 27 to convert to cubic yards
Understanding the difference between linear yards and cubic yards will help you estimate concrete accurately, avoid costly mistakes, and ensure you order the right amount of material for your project.
