Convert square feet to square yards and back. 1 yd² = 9 ft². Use for carpet, fabric, landscaping, and US lot size estimates.
How the conversion works
1 square yard (yd²) equals exactly 9 square feet (ft²) because 1 yard = 3 feet, so 1 yd × 1 yd = 3 ft × 3 ft = 9 ft². To go from square feet to square yards, divide by 9. To go from square yards back to square feet, multiply by 9. Example: a 180 ft² living room equals 180 ÷ 9 = 20 yd² of carpet.
What is a square yard?
The square yard (yd²) is a unit of area in the US customary and imperial systems, defined as the area of a square with sides 1 yard (3 ft, 36 in, or 0.9144 m) long. It equals 9 ft², 1,296 in², or approximately 0.8361 m². Square yards are widely used in the US for carpet, fabric, landscaping, and concrete estimates.
Carpet and flooring
US carpet is priced per square yard, while room dimensions are almost always given in feet. To get the carpet order: measure the room length and width in feet, multiply for ft², then divide by 9. A 12 ft × 15 ft bedroom is 180 ft² ÷ 9 = 20 yd². Add 10% waste for cuts and seams — order 22 yd².
Fabric, upholstery, and yardage
Fabric stores in the US sell by the linear yard (36 in long, full bolt width typically 54–60 in). For upholstery jobs quoted in square feet, divide by 9 to estimate yardage. A 45 ft² sofa reupholstery needs 5 yd² of fabric, which at a 54-inch bolt width equals roughly 3.3 linear yards plus pattern-match waste.
Landscaping, sod, and concrete
Sod is usually sold in rolls or pallets rated by square feet, but larger landscaping estimates switch to square yards. For concrete slabs, contractors quote thickness in inches, area in ft², and volume in cubic yards: 1 yd³ = 27 ft³ covers 81 ft² at 4 in thick. Converting ft² to yd² helps sanity-check quotes across units.

Frequently asked questions
How many square feet are in a square yard?
One square yard equals 9 square feet exactly. This is because 1 yard = 3 feet, and area scales as the square of the linear ratio: 3 × 3 = 9. So 1 yd² = 9 ft², 2 yd² = 18 ft², 5 yd² = 45 ft², and 100 yd² = 900 ft².
How do I figure out carpet for a room?
Measure the room length and width in feet (round up to the nearest foot), multiply to get square feet, then divide by 9 for square yards. Always add 10–15% for waste, pattern match, and seams. For a 10 ft × 12 ft room: 120 ft² ÷ 9 = 13.33 yd², order 15 yd² with waste included.
Is a square yard the same as a yard squared?
Yes, "square yard" and "yard squared" mean the same area unit: a square with each side 1 yard long, or 9 ft². Do not confuse it with a linear yard (36 inches long), which is a length measurement used for fabric bolts and tape lines in US football.
How does a square yard compare to a square meter?
1 square yard = 0.83613 square meters, so a square meter is about 19.6% larger than a square yard. For quick conversions: multiply yd² by 0.836 to get m², or multiply m² by 1.196 to get yd². 1,000 yd² = 836.13 m² = 0.0836 hectares.
What is a typical US lot size in square yards?
A standard US suburban lot of 1/4 acre is 10,890 ft² = 1,210 yd². A 1/2 acre lot is 21,780 ft² = 2,420 yd². Urban townhome lots run 1,500–3,000 ft² (167–333 yd²), while rural parcels of 1 full acre equal 43,560 ft² or 4,840 yd².
Convert between square feet (ft²) and square yards (yd²) for US carpet, flooring, fabric, and landscaping estimates. The converter runs both directions with one tap and shows equivalent area in square meters, square inches, acres, and hectares. One square yard equals 9 square feet because 1 yd = 3 ft, and area scales as the square of the linear ratio. Example 1: a 12 × 15 ft bedroom is 180 ft² ÷ 9 = 20 yd² of carpet; add 10% waste and order 22 yd². Example 2: reupholstering a sofa that needs 45 ft² of fabric equals 5 yd², or about 3.3 linear yards of a 54-inch bolt.
