About the Square Yard
Facts & Uses
- 1 yd² = 9 ft² = 0.83612736 m² exactly. The traditional unit for fabric and carpet sales in the US and UK.
- Standard for carpet pricing (per yd²), fabric and upholstery, landscape materials (mulch, gravel coverage), and concrete pours.
- Used in football field calculations: an American football field is 5,531 yd² (300 × 160 ft); a soccer pitch is around 8,000 yd².
- Convenient because fabric bolts are typically 1-1.5 yards wide, so width × length naturally produces square yards.
Curiosities
- Many US carpet retailers price by the square yard, while flooring (tile, laminate) prices by the square foot — a frequent source of cost comparison errors (1 yd² = 9 ft²).
- The yard was historically defined as the distance from the king's nose to fingertip; the international yard is now exactly 0.9144 m by 1959 agreement.
- A standard cubic yard of concrete covers about 81 ft² at 4 inches thick — useful for sidewalk and patio estimates.
- Approximate equivalents: 1 yd² ≈ 0.836 m² = 9 ft² = 1296 in².
