How to Calculate Carpet Needed
Formula
Square Yards = (Length × Width) / 9
Carpet is sold by the square yard in the United States. One square yard equals 9 square feet (3 ft × 3 ft). Add 10% for waste due to seams, pattern matching, and room irregularities. Carpet typically comes in 12-foot wide rolls.
Example Calculation
A room 15 ft by 12 ft at $30 per square yard with 10% waste.
- 01Area = 15 × 12 = 180 sq ft
- 02Square yards = 180 / 9 = 20.00 sq yd
- 03With 10% waste = 20 × 1.10 = 22.00 sq yd
- 04Cost = 22.00 × $30 = $660.00
