A 12x12 room (144 sq ft) costs $500-$1,300 installed in 2026 with carpet, pad and labor. Mid-range nylon is typically $720-$1,000 installed.
About 17.6 sq yards (144 sq ft + 10% waste = 158 sq ft ÷ 9).
Standard mid-grade nylon ($720-$1,000 installed) gives the best 10-year value. Skip premium wool unless it's a master suite — the wear difference isn't visible in light-traffic bedrooms.
Home Depot charges $504-$1,274 to fully carpet a 12x12 room in 2026 ($3.50-$8.85/sq ft installed all-in).
