Quick answer: square yards = length (ft) × width (ft) ÷ 9. A 12 × 15 ft room is 180 sq ft = 20 sq yd.
How to calculate square yards
- Measure the length and the width. Any unit works; the calculator converts.
- Multiply length × width to get the area. In feet, that gives square feet.
- Divide square feet by 9 (a square yard is 3 ft × 3 ft). From meters, divide m² by 0.83612736.
Example: a bedroom 12 ft by 15 ft is 12 × 15 = 180 sq ft, and 180 ÷ 9 = 20 square yards. Measured in meters, 4 × 5 m = 20 m² = 20 ÷ 0.83612736 = 23.92 sq yd.

The factors follow from the international yard of 1959: 1 yd = 3 ft = 0.9144 m exactly, as published by NIST.
Frequently asked questions
How do I calculate square yards?
Measure the length and width in feet, multiply them to get square feet, then divide by 9. A room 12 × 15 ft is 180 sq ft, which is 20 square yards.
How many square feet are in a square yard?
Nine. A square yard is 3 ft × 3 ft, so it holds 9 square feet. To go back, multiply square yards by 9.
How do I convert square yards to square meters?
Multiply by 0.83612736. That figure is exact, because a yard is defined as exactly 0.9144 m. 20 square yards is about 16.72 m².
How many square yards of carpet do I need?
Work out the floor area in square yards and add extra for seams, pattern matching and the roll width, usually 5–15%. Carpet comes off a roll of fixed width (often 12 ft in the US), so the installer’s seam plan decides the final amount; use this result as the starting point.
How do I measure an L-shaped room?
Split it into rectangles, enter each one with “+ Add another area” and the calculator adds them up.
