Frequently Asked Questions

Measure each room's length × width in feet, convert to square yards (divide sqft by 9). Carpet is sold from 12-ft wide rolls, so rooms wider than 12 ft require seams. Add 10% for waste. For a 12×15 ft room: 180 sqft = 20 sq yards.

Carpet itself costs $2-8/sqft for material. Padding adds $0.50-1.50/sqft. Professional installation is $1-3/sqft. Total cost for a 500 sqft area: $1,750-6,250. Budget for old carpet removal ($0.50-1.00/sqft) and furniture moving.

Nylon (plush or frieze) is most durable for high-traffic areas. Berber/loop pile resists crushing and shows less wear. Triexta (SmartStrand) offers excellent stain resistance. For bedrooms, plush or saxony provides the softest feel.
