How do I convert square feet to square yards for carpet?

Divide square feet by 9 to get square yards. One square yard = 9 square feet (3 ft × 3 ft). For example, a 180 sq ft room needs 180 ÷ 9 = 20 square yards of carpet.

How much extra carpet should I order?

Order 10-15% more carpet than your measured area to account for waste from cuts, seams, pattern matching, and irregularly shaped rooms. For patterned carpet, add 15-20%.

How wide is a standard carpet roll?

Standard carpet rolls are 12 feet (3.66 meters) wide, though some come in 15-foot (4.57 m) widths. Planning your layout around these widths minimizes seams and waste.

Key Carpet Conversion

Square yards = Square feet ÷ 9

Carpet is priced per square yard in many stores, but rooms are measured in feet. This single conversion is essential for accurate cost estimation.

Room Size Quick Reference

Room (ft)	Sq Feet	Sq Yards	Sq Meters
10 × 10	100	11.1	9.3
10 × 12	120	13.3	11.1
12 × 14	168	18.7	15.6
12 × 16	192	21.3	17.8
14 × 18	252	28.0	23.4
16 × 20	320	35.6	29.7

How to Measure a Room

Measure the longest width and length in feet
Multiply width × length = square feet
For L-shaped rooms, divide into rectangles and add areas
Add 10-15% for waste and cuts
Divide by 9 for square yards

Cost Estimation

If carpet is $30 per square yard and your room is 180 sq ft:

180 sq ft ÷ 9 = 20 sq yd
Add 10% waste: 22 sq yd
Cost: 22 × $30 = $660 for carpet material
