Quick Answer
A unit of area equal to 9 square feet, commonly used for carpet and paving.
Definition
Definition
A square yard is a unit of area equal to 9 square feet (3 feet × 3 feet). Square yards are used to price and specify flooring materials such as carpet and vinyl sheet goods, as well as asphalt paving materials and certain concrete flatwork applications. Converting between square feet and square yards requires dividing by 9.
Context
Why It Matters in Bidding
Mixing up square feet and square yards is one of the most common takeoff errors on flooring and paving bids, and a missed division by 9 inflates a quantity ninefold. Because carpet, sheet vinyl, and asphalt are often quoted by the square yard while plans dimension everything in feet, the estimator must convert cleanly to avoid either grossly overbidding or shorting the scope.
Example
Example
An estimator measuring a 1,800-square-foot office suite divides by 9 to order 200 square yards of broadloom carpet, then adds waste and pattern-match allowance before pricing the sub.

FAQ
Questions Contractors Ask
How do you convert square feet to square yards for a takeoff?
Divide the total square footage by 9, since each square yard equals a 3-foot by 3-foot area. For irregular rooms, calculate each rectangle in feet first, sum them, then convert once at the end to reduce rounding error. Always add a waste factor after converting, not before.
Why is carpet still priced by the square yard?
Broadloom carpet is manufactured in fixed roll widths, traditionally 12 feet, so material and labor pricing evolved around yard-based goods. Many mills and installers still quote per square yard out of convention, though some now use square feet, so confirm the unit on every quote before comparing subcontractor numbers.
Does asphalt paving get measured in square yards or tons?
Both. Surface area for a paving lot is typically taken off in square yards, while the asphalt material itself is purchased and delivered by the ton. Estimators convert square yards plus lift thickness into tonnage using the mix density so the area takeoff and the material order reconcile.
